The advice in this book is designed to help you achieve the standard
of Cisco Certified Network Associate, which is Cisco’s foundation
internetworking examination. A CCNA can carry out basic router and
switch installations and troubleshooting. Before you carry out more
complex operations, it is advisable to seek the advice of experts or
Cisco Systems, Inc.
The practical scenarios in this book are meant to illustrate a
technical point only and should be used on your privately-owned
equipment, never on a live network. The output on our routers and
switches may differ from yours due to IOS and platform model.
FOREWORD
If you are reading this book, you are embarking on the road toward
becoming a Cisco-certified networking engineer. Or at the least, you
are contemplating the journey and are curious to know what lies
ahead.
It was not too many years ago that the only technical certification
Cisco Systems offered—indeed, the only serious internetworking
certification anyone offered—was the Cisco Certified Internetwork
Expert (CCIE) certification. Acquiring the CCIE meant months of
intensive study to tackle a hands-on lab, the details of which were
mysterious to most. Those who passed the lab (few passed on their
first or even second attempt) had lengthy hands-on experience in
internetworking before even beginning their course of preparation.
Only a very few intrepid individuals passed the CCIE lab without
extensive prior experience.
Cisco Systems has, since that time, added to their program a
number of intermediate certifications that can be used as stepping
stones toward the coveted CCIE. You must still, in the end, prove
your expertise in the dreaded hands-on lab, but these intermediate
certifications are wonderful for getting you acclimatized to the rigors
of testing your skills and knowledge without having to step into the
most difficult of them cold.
The first milestone on the certification path is the Cisco Certified
Network Associate (CCNA), the subject of Paul Browning’s
outstanding preparation guide. Within these pages, Paul imparts to
you the knowledge you need to pass the CCNA exam, step by step,
using abundant illustrations, examples, and exercises. But beyond
the coursework, in this book you will find the practical advice
necessary for gaining hands-on experience and preparing for the
certification exam that will benefit you not only for the CCNA but
also through subsequent Cisco certifications to whatever objective
you set for yourself.
Follow the advice and exercises Paul has provided for you here and
you will have made an excellent start.

INTRODUCTION TO THE 5TH
EDITION
I wrote the first edition of Cisco CCNA Simplified while working at
Cisco TAC. My manager had just informed us that our entire
department was being made redundant. All of our jobs were being
outsourced to Manila in the Philippines. We were thanked for our
hard work and asked to keep it up until our last day which, for some,
would be in the next month.
In a panic, I contacted a company I’d attended for some PC
assembly training a few years earlier. I offered to run a Cisco course
for the owner if he could fill it from his list of former students, and
we could split the profits. Within the hour, he called back and
accepted the offer. By the next week, I had a date to teach eight
students the Cisco CCNA syllabus.
I spent the next few weeks writing some study notes for the
students to accompany the course. At that time in 2002, there was
only the Cisco study guide and one from Sybex. Neither had any labs
included, which shocked me. Even though the CCNA exam was
theory only, surely students would want to get at least some hands-
on time with routers and switches.
I had a few advantages over the other publishers. I had started from
the bottom, I was still working on live networks, and I was regularly
teaching the material to students. I had feedback every day from
people telling me what was working, what needed further
explanation, and where more (or less) labs were required. I also
invented my own easy subnetting method to help students answer
any subnetting question within around 30 seconds (it’s in this book
also).
I eventually published the book and, to my amazement, it became
an Amazon best seller. All of a sudden I was receiving messages
from people all over the world from all walks of life who were using
my book to pass the exam, which led to networking jobs in large
corporations and even the government.
For this reason, I’ve updated this study guide every time Cisco
updated their exam, which is every three years, resulting in this
latest version.
The current CCNA Routing and Switching exam represents some of
the biggest changes in many years. Cisco has reintroduced many of
the networking basics they removed, such as topology types, but
also added many topics that were previously at the CCNP level, such
as BGP, GRE, QoS, DHCP snooping, and more. They have also added
Software Defined Networking, cloud computing, and virtualization.
The network engineer’s job is rapidly changing and this is reflected
in the Cisco CCNA syllabus. It’s important that you review the
syllabus from Cisco’s website before you take the actual exam
because they reserve the right to make changes. Bear in mind that
the syllabus is a guideline so they also reserve the right to ask you
questions about topics not included in the syllabus. I state this
because I get the occasional angry e-mail from students stating that
this happened to them and blaming me.
We’ve scrapped around 15% of the material from the previous
version of Cisco CCNA Simplified and added around 30%, so your
workload has increased as has the level of difficulty. The mini-labs
were really popular so you will find a lot more in this version. If you
need anything else or want more topics or labs, then visit the
support page at https://www.howtonetwork.com/ccnasimplified and
hit me up. Please bear in mind that it has to be relevant to the exam
though.
The URL above has a ton of exam support material, so please use it
BEFORE you attempt the exam or you will surely fail.

INTRODUCTION
The Problem with CCNA Study
Guides
I failed my first attempt at the Cisco CCNA exam. I studied four
hours per day for around three months, but I was smashed in the
exam and fell short of the required pass mark. With the benefit of
having worked for Cisco Systems, running my IT consulting
company, and then an IT training company specializing in Cisco
networking, I now realize the problem.
First, most Cisco manuals are written by trainers who haven’t
worked on a live network for years. They moved into training years
or decades ago and stayed there. As you know, IT changes quickly
and if you don’t use your skills on live networks, they get rusty fast.
I experienced this myself when I started teaching, which is why I
decided to keep freelancing on the side and hire three top Cisco
consultants who design, install, and troubleshoot enterprise
networks on a daily basis to help me write this book.
This inspired me to ask the technical editor, Dario, to add his
comments whenever he felt he had something useful to add. It could
be an important change to industry best practices, a change to
default IOS commands, or even a configuration tip that you will
benefit from in the real world. Keep your eyes peeled for a photo of
Dario when he has something to add.
“Hi, from me. I’m a Dual CCIE working on enterprise-class
networks that span the globe. Because I design, install, and
troubleshoot very large networks, I’ll be sharing with you some of
the things I’ve learned to help you pass the CCNA exam and
become a better network engineer.”
Second, if around 60% of the CCNA exam’s final score comes from
hands-on labs and troubleshooting, then where are all the labs? At
most, CCNA study guides will give you a few lines of configuration to
copy but this falls well short of the mark for what you need to know
for the exam. In the CCNA exam, you will be asked to configure and
troubleshoot complex topics, including routing, security, and
switching, using the Cisco configuration commands. All this will be
timed, adding even more pressure.
For this reason, I’ve added 43 mini-labs that you can copy to help
you understand how to configure the technologies. There are also 32
end-of-chapter full labs where you will follow my configurations of
more complex protocols and services, and you will see the full router
and switch configurations as well. I’ve also included advanced labs
that you will find particularly challenging. These advanced labs
feature multiple layers of routing, security, and protocols that would
test any CCNA-level engineer to his or her limits.
Cisco CCNA Simplified versus Cisco
CCNA in 60 Days
I seem to be best known for my Cisco CCNA in 60 Days study
system, but that was, in fact, the seventh Cisco study guide I’d
written.
I had no idea that when I printed the book, it would become an
international best-seller. It was used by many thousands of students
and Cisco trainers for years, but when Cisco added one of its three
yearly updates to the exam, I decided to replace Cisco CCNA
Simplified with another study guide called Cisco CCNA in 60 Days. I
figured that breaking everything down into daily study tasks, exams,
and hands-on labs was a far better solution, and the results were
amazing. Every week I hear from students who tell me that they’ve
finally passed the exam after wasting months or even years trying
other methods.
But over time, I also heard from other students—busy parents who
were raising young families and people who were working long
hours or had other time constraints simply couldn’t put in the two
hours per day required by the Cisco CCNA in 60 Days study system.
I realized that there needed to be an equally effective but somewhat
less intense study method. For this reason, I decided to do a
complete rewrite of Cisco CCNA Simplified, not only to update it with
all the latest exam topics but also to improve on the entire study
experience based on what I’ve learned over the last 15 years in the
IT industry that really works for students.
This is an entirely new and different book from Cisco CCNA in 60
Days, so you are best off using just one of these two study methods.
If you’ve bought this book (as opposed to reading a sample or
browsing through it at a book store), then stick with this book and
find another CCNA manual to use for reference if you need one.
Free Bonus Material
I’ve learned so much since publishing my first Cisco study guide.
One of the main lessons is that even with hundreds of proofreadings
and technical edits, mistakes still creep in. Even the mighty Cisco
Press is often heavily criticized for having a large number of errors in
their manuals. For this reason, I’ve added free bonus website
access. On the URL below, you will find:
Errata
End-of-chapter interactive exams
Bonus labs (with solutions)
Bonus exams
Other study goodies
https://www.howtonetwork.com/ccnasimplified
This gives me an easy way to ensure that I plug any gaps in the
learning that you get from the study guide, as well as save on the
size of the manual, which would be over 1,000 pages if I added all
the extra bonus goodies here.
I also have an older website for the old version of the CCNA exam.
Around 70% of the content is still relevant for the current exam, but
because I’ve updated it all I made it free access. Just bear in mind
that it doesn’t match the current exam syllabus but, nonetheless, it
has a lot of useful videos, exams, and labs. It’s at
www.howtonetwork.com.
Cisco CCNA Simplified Video Course
All you need to pass your CCNA exam is this book, the free online
exams you get access to, and hands-on time with some form of
Cisco rack. I will go into more detail on your rack options in the
“How to Do the Labs” section below.
I also run an online IT certification website called
https://www.howtonetwork.com/ccnasimplified, where I’ve added a
video training course to accompany this study guide. Membership
also includes access to over 30 other IT training courses and two live
Cisco racks. For those of you who are just about to jump over to
Amazon to kick me for “selling” stuff, I want to make it clear that
you DO NOT NEED the video course. It’s there for anyone who
prefers lectures as a learning style.
Unfortunately, I have to make a small charge for access to cover the
thousands of gigabytes of streaming video costs and the hosting and
power costs of the live Cisco racks and web hosting, but it works out
to be just 66 cents per day ($20 a month). Just to be clear once
again, you don’t need to use the video course to pass the exam, so
if money is tight, you are all set with what you already have.

minutes after he was there—I bet you. I bet it was sent in while you
were standing up at the corner watching where he went—I bet you.”
“Gee, some bets!” said Craig. “I bet that in a couple of days or so,
or in a week maybe, they’ll arrest somebody for that robbery and I
bet Chesty McCullen will admit it was the one that told him to send in
the alarm.”
“I bet you he won’t,” Hervey shouted.
“I bet you he will,” Craig shouted.
Hervey was aroused to high excitement. Ordinarily he was too
amiable, or perhaps too little interested in such matters, to get into
disputes with other boys. He was for action rather than argument. He
was too free and easy to quibble. And as for scouting, he was the
last one to be discussing its nice points with scouts in good standing.
He was not aroused about any such matter now. He was thinking of
poor little Chesty McCullen and trying to square himself with Chesty
by vigorously defending him.
“You’re a couple of tin-horn scouts,” he shouted. “Such swell
detectives, you get your names in the papers catching criminals and
everything, you make me laugh! If anybody rings the fire-alarm the
whistle will blow inside of one minute. You even admit it didn’t blow
for maybe ten minutes. How do you know what happened in those
ten minutes. Could you watch where Chesty was going and watch
that fire-box too? You’d have to have eyes in the back of your head
and you haven’t even got eyes in the front of your head!”
“Listen, Herve,” said Craig, becoming serious and very friendly;
“cut it out; what’s the use scrapping? The cops said what we did was
all right. Why don’t you be a scout yourself? You never come to
meetings, you never go round with us, you never chip in, you don’t
bother about merit badges or anything—gee! Now when Warner and
I do something like scouts are supposed to do, you come around
and jump all over us. What are you sore about, anyway? We saw
Chesty there, and we saw him run when he heard us, and we went
to the police station and told about it. Jiminy crinkums, what are you
so sore about, Hervey?”
Ah, that was it! What was he so sore about? This young free lance
who did not take any interest in the concerns and doings of other
boys. Why all this pother? And what was the matter with these two
good-natured scouts who had been content to camp on the Lewis
lawn while Hervey Willetts was driving the management to
distraction up at Temple Camp? They were pretty good scouts.
Suddenly, Hervey must descend upon them with technicalities and
storming denunciation. What was he so sore about?
“I never knew you took so much interest,” said Warner Lewis. “Will
you stay and help us cook lunch? We’ve got some spaghetti.”
“Do you say it wasn’t mean to get that kid arrested?” Hervey
demanded.
“We didn’t get him arrested, we only went and told what we saw,”
said Craig. “Any one would think he was your brother.”
“He let me use his father’s boat,” Hervey said. “If I stay and eat
with you will you go with me to-night and the three of us will set him
free? I know how we can do, I’ll show you! all we need is a rope.”
Craig and Warner laughed heartily. “Come out of it, Herve,”
Warner said.
“All right!” thundered Hervey. “I’ll show you who’s a real scout! I’ll
show you how to track a feller! I’ll show you how to get your name in
the papers!”
“I don’t see what you’re so sore about?” repeated Craig.
“I’ll show you how to make a noise like a scout!” Hervey fairly
yelled.
“Go ahead, now you’re talking,” said Warner.
“I’ll do more than talk,” Hervey screamed at him. “I can—I told my
father whatever a scout can do, I can beat him at it! I can do
anything that any scout in any troop can do, and then I can take him
out and lose him!”
“Goodness me,” said Warner.
“I’ll smash your little stunt for you—you see,” said Hervey with
gleaming eyes. “Do you dare me to? Do you dare me to? Do you say
I can’t set Chesty McCullen free—do you dare me?”
“There you go with your dares,” said Craig.
“Do you dare me to; do you say I can’t?” Hervey demanded with a
steely look.
“Yes, we dare you to, and we say you can’t, and we say you’re a
fool,” said Warner.
“I’ll make a noise like a scout for you!” shouted Hervey.
That was pretty good. It would be hard to analyze Hervey’s
impulses in all his boastful excitement, and to say whether he was
sore at those two boys or sore at himself. He himself hardly knew
what was the matter with him. But he was going to trample those two
boys in the dust and make a noise like a scout. Not for a moment did
he admit that he was going to hit the scout trail with a vengeance
and cleanse his own soul of a yellow stain that was upon it.
CHAPTER XIV
AT THE BAR
“If you fool around that jail, you’re crazy and you’ll get yourself in
trouble,” Craig called after him.
“I’ll free him,” shouted Hervey. “I’ll have everybody in town
laughing at you—a couple of half-baked detectives! You must have
been reading Young Sleuth, the Boy Detective. I’ll show you.”
“You’re a fool, Herve,” was the last he heard.
It was odd how, even at his best and on the right trail, he must
work differently from other boys and quite alone. He might have
sought the advice and co-operation of these good scout comrades.
But he must make them out worse than himself and leave them
astonished and bewildered. He must get things all askew in his mind
and conjure an honorable act into a sort of stunt. The throwing down
of a dare! He could not just do the right thing for its own sake. Yet he
could not bear the lashings of his own conscience. We can only
follow in his trail and see where it leads. And it leads through strange
and devious ways, I promise you.
In this episode of his story it led to a good destination—the police
station. There was nothing contrite or remorseful about him as he
faced the elevated desk at which the sergeant sat facing him. The
frowning officer gazed down upon him and took in at a glance the
brown face, the dancing, daredevil, gray eyes, the huge hole in his
stocking. He fixed a quizzical look of scrutiny on the rimless hat,
Hervey’s most treasured and original possession, which seemed to
set him apart from all other boys on the face of the earth, embodying
as it did the very essence of the bizarre. The sergeant leaned
forward and read with interest the largest tin button on that
perforated felt crown—Be good and you’ll be happy, and another
which said Keep smiling.
“You better take your hat off,” he said.
Hervey took off his hat.
“Well, young feller, what’s troubling you?”
“I came to tell you that I’m the one who turned in that false alarm,”
said Hervey. “I did it because a feller that I met dared me to. Maybe
he was a burglar, but anyhow you got to prove it to me first. Maybe
the police are only fools thinking he’s a burglar. Those two scouts
are a couple of fools because they admit they were up at the corner
and they didn’t even see me, they’re such punk scouts. I can show
you my own tracks in the field. So you better let Chesty McCullen go
home, because he didn’t do it.”
“Go easy, young feller,” warned the officer, “you’re puttin’ too many
fools in your talk. So you sent in the alarm, huh? What’s your
name?”
The chief strolled in, leaned against the desk and listened while
Hervey told the story of his encounter with the stranger who had
thought up the hot tamale stunt. Then this scout who was no scout,
or this happy-go-lucky boy who was one (suit yourself) was held on
the charge of malicious mischief.
“So that’s what you call a hot tamale, is it?” the sergeant asked.
“It’s a hot tamale,” said the chief. It was not clear whether he was
characterizing the stunt or the fact of Hervey’s coming and giving
himself up. That was a pretty good hot tamale. The chief was in
about the same uncomfortable predicament that Councilor
Wainwright was in when he dismissed Hervey from Temple Camp.
But like Councilor Wainwright he had his duty to perform.
So Hervey was held on the charge of malicious mischief and they
called up Walton’s Stationery Store and told poor Mr. Walton about it.
And meanwhile, they liberated little Chesty McCullen and told him
that he had better not loiter around on corners and near fire boxes.
He went scuffling home where his poor, scrawny, overworked mother
was relieved to learn that her elder son, absent from home, was no
longer wanted. Thus Chesty McCullen got a sort of a backwash from
scouting; he was later to be borne upon its rising tide.
Poor Mr. Walton hurried to the station, a lanky, elderly man with a
troubled countenance. They knew him and respected him. He was
more troubled than Hervey, for Hervey was triumphant, whereas Mr.
Walton was just humiliated.
“Well, Hervey,” was all he said.
“He came and told us of his own accord,” said the chief. “He’s a
little devil, but a white one.”
Mr. Walton nodded.
“They’re so smart, not; thinking they can send a feller to jail,” said
Hervey. “They dared me that I couldn’t set him free, so who’s got the
laugh?” Mr. Walton did not have the laugh, at all events. He listened
soberly as they told him that Hervey would have to be taken before
the recorder for proper disposition of the case. Such things get
around like wildfire and even before the little party with the culprit
had started for the recorder’s court, a couple of reporters were upon
the scene, scenting perhaps some move in the more important end
of the case. Instead of a burglar they saw only a rather bewildered
boy as the center of attraction. And they listened and made the most
of it as Hervey gave a description of the stranger for whom he had
performed. It may be told now that that stranger was never found;
nor was it ever proven that Hervey had played the dupe and all
unconsciously been an accessory to a major crime.
As for his own excursion in the dangerous field of malicious
mischief, he was lucky as he always claimed to be. Poor Mr. and
Mrs. Walton suffered more keenly than he.
“Of course this kind of thing can’t be tolerated,” said the recorder.
“Tampering with the public emergency apparatus is a serious
business.” Hervey had never supposed that he had done that. He
knew he had sent in a false alarm. But “tampering with the public
emergency apparatus”—that sounded pretty big. It had been even a
greater stunt than he had supposed. Mr. Walton could only stand
and listen. The recorder was a young lawyer and liked to hear
himself talk and see people hang with suspense upon his words. Let
no one say that the law is no respecter of persons. Poor Chesty
McCullen would have been fined for this offense and his father would
not have been able to pay the fine and Chesty would have spent a
week or two in jail. He owed more to Hervey than to the law.
“I think,” the recorder said, addressing Hervey, “that you have had
a good lesson. I think you realize the seriousness of what you did.”
(He was never more mistaken in his life.) “I think you are sufficiently
punished,” he added.
“Those fellers are punished too,” said Hervey.
“But if you are ever brought here again,” the recorder continued,
“this affair will be remembered and it will go hard with you.” He
glanced significantly at Mr. Walton, as if to say that he thought a little
warning of that sort was a good thing. “Now young man, you go
home and look out who you make friends with and don’t try to show
off.” He did Hervey an injustice there, for most of our hero’s exploits
were performed when he was quite alone and he never “showed off.”
If that were all there were to it, it would be easy to comprehend him.
Out of his mortification Mr. Walton, always fair, must say one last
word. “I think, your Honor, that it is to his credit that he came here
and gave himself up just when his safety seemed assured. I’m not
quite sure about his motive, but I suppose we ought to judge people
by their acts and get at their motives that way.”
“I’d rather you’d try to work out his motives than I,” smiled the
young judge. And Mr. Walton bowed acknowledgment.
He said not one single word to Hervey except to lay his hand on
the boy’s shoulder as they left the place. Perhaps it meant that he
was pleased that in the big essentials his stepson had not been tried
and found wanting. But he seemed disheartened and if Hervey had
been approachable through the channels of sentiment, he would
have felt a little twinge as this plain, kindly man went off down the
street, back to his stationery store.
CHAPTER XV
CHESTY, AMBASSADOR
There was time enough that afternoon for Hervey to stage the
climax of the latest dare. He wished to do this before the evening
paper appeared. It was not by way of showing off, but according to
the ethics of dares and stunts the performer must always report and
confound his challenger. It is amusing how punctilious Hervey was in
such matters.
He was probably the only boy in the upper world of Farrelton who
knew where to find Chesty McCullen. But Farrelton had an
underworld too, a sprawling group of hovels down by the river, and
here Chesty lived. The neighborhood was one of Hervey’s familiar
haunts. Chesty, now thoroughly aroused to the perils of Farrelton,
could not have been dragged there by wild horses, but for Hervey he
would do anything.
“I set you free,” said Hervey, “so you have to pay me back. You
have to go up to New Street and see Warner Lewis and Craig
Hobson and tell them I sent you. You must only just say to them that
they dared me I could get you out of jail so now they got their
answer. Seeing is believing, you tell them that. You’ll see a tent on
the lawn of one of those houses near the fire-alarm box; that’s where
they are. And you can tell them they’re a couple of sap-headed fools
and they can take their scout troop and go to blazes with it. You just
tell them that. You say I sent you because seeing is believing and
they get their faces washed with their own dare.”
Chesty did not know about this errand, undertaken so soon upon
his release from jail. But he could not refuse Hervey and he had not
the wit to inquire why his hero did not deliver this high-handed
address in person. It may be assumed that Hervey had his reasons;
perhaps he thought that the effect would be better with himself
withdrawn from the scene.
He was on time for supper that evening and did not venture to
absent himself afterward. Instead he waited for the talk which all
through the meal he suspected his father was reserving for a quiet
session in the living room.
“Now, Hervey,” said Mr. Walton, “this matter is closed. You did
right to go and give yourself up—I don’t want to hear your reasons.
What you did was right. And I think that you did it because you
couldn’t get comfortable till you did. So we won’t give too much credit
to your dare or your stunt or whatever it was. I⸺”
“Just the same I’ll never do anything for the scouts,” Hervey flared
up. “I’m through with that bunch for good and all. They got Chesty
McCullen in jail; one of those fellers is a monitor in school, so that
shows you what kind of a feller he is. Nix on that outfit. I’m going
perch fishing with Chesty to-morrow and I’m going to blow him to a
soda too. He’s a poor kid and look what he got—some deal, I’ll say.
That kid can beat any of that bunch swimming.”
Mr. Walton listened soberly, his lips pursed. “But you see if you
hadn’t sent in the false alarm, Chesty wouldn’t have got in trouble.
You got him out, but you also got him in. Isn’t that so, Herve?”
“I never squealed; no siree, I never did that.”
“Well, the matter is closed now anyway, Herve,” Mr. Walton said,
despairingly. “I’m sorry you’re dropping out of the Scouts. But of
course, I’d rather you’d drop out altogether than be a scout slacker.
So you’ll just have to suit yourself. Now what I want to say to you is
this. You mustn’t get into trouble again. Last year you caused us a
great deal of worry and I sent you up to Temple Camp thinking you’d
find a suitable field of enjoyment there. So far I haven’t heard you
say one word about your summer at Temple Camp. In the spring you
encouraged Mr. Allerton’s dog to follow you for miles and he got run
over and I had to settle with Mr. Allerton. You got in trouble for some
absurdities last Hallowe’en, taking furniture from porches.
“Now you heard the judge say that if you ever came before him
again, it would go hard with you. I just want to tell you, Herve, that in
such a case you can’t count on me; you’ll have to take the
consequences. I don’t mean that I’d let you go to jail; I know you
wouldn’t commit a crime—be dishonest. But if it should ever seem
advisable to send you away to some sort of military or training
school, perhaps, where you will be under rigid discipline I would not
discourage such a course. There are places where they send boys
who are hard to manage. I think school opens a week from Monday,
doesn’t it?”
“Yop, but Hairpin Wilkens isn’t going to teach mathematics this
year, that’s one good thing.”
“And you’ve left the Scouts?”
“I threw them down flat,” said Hervey. “But, one thing, I’m going to
show Chesty McCullen a good time; look what he was up against—
oh bimbo!”
“I think that’s a good idea, Herve,” said Mr. Walton. “Why don’t you
take him to the movies? Isn’t there a cowboy play at the Lyric?”
“Nix on looking at that stuff; it only makes me want to get out on a
mustang. That’s what I want to do most of all—ride a horse, a good
wild one. Montana, that’s where I’d like to go. Don’t you think the
train robbers are all dead—they’re not.”
“No, I don’t suppose so.”
“I want to go on a ranch, that’s what I want to do.”
“Yes, but even on a ranch you’d have to obey orders. Ranches are
run by rules. The whole world is run by rules, Herve.”
“Some punk rules, I’ll say.”
“Either you’ve got to do the world’s way, or else you’ve got to
make the world do your way—and I’m afraid you can’t do that. Isn’t
that so, Herve?”
“Bet your life,” said Hervey.
“Well, you take Chesty out and give him a good time; I think that’s
a fine idea.”
“Sure, after being in jail like that,” said Hervey. The very idea of
imprisonment was terrible to Hervey. To be confined, kept in; it was
horrible, unbearable. He was the grand champion of freedom.
CHAPTER XVI
TO PASTURES NEW
The next morning Hervey went hunting for Chesty McCullen. He
explored the neighborhood of Chesty’s wretched home and was
finally driven to make inquiry at the very portals. He had never been
squeamish about the character of his companions nor the scenes
into which his casual acquaintanceships led him. But he could not
fail to notice the squalid environment which was so different from
that of his own home. He never thought of anything he did in the light
of a good turn (that would be to pay a tribute to the Scouts), but he
was going to show Chesty McCullen a good time and “blow him to
soda,” because Chesty had been the unhappy victim of scout
bungling.
But Chesty was not to be found. His poor, scrawny mother, busy
with the washings that she took in and exhaling an odor of soap
suds, told Hervey that he had gone away early, she didn’t know
where. She thought he might have gone to bring home a “washing”,
but she corrected this supposition on seeing his ramshackle cart in
the yard. Hervey himself had often seen this outlandish vehicle on its
two wobbly wheels. It was so inseparable from its maker and owner
that it even looked strange standing in the cluttered back yard quite
apart from its motive power. Hervey had never seen it at home
before; poor Chesty was always pushing it around town with
“washings” or miscellaneous kindling wood piled into it.
He went away disappointed, not knowing what to do. He had (in
his own view) outlawed himself from the Scouts, and on the other
hand he could not venture forth on any adventurous escapade. He
knew that for a while he had better walk the straight and narrow
path, and not get into any kind of trouble. His stepfather had been
considerate with him, but just the same he sensed a certain
something in Mr. Walton’s demeanor which boded ill for any bizarre
and illicit enterprises. It seemed to him that his stepfather had
resolved to let this little matter of the fire-alarm dare pass and to
concentrate his anger and action on the next venture. There was
something ominous in his very leniency, which Hervey had not failed
accurately to construe.
That morning he occupied a place on the swinging crane of a
steam shovel that was relentlessly digging an excavation for a new
building on the business thoroughfare. He continued so enthroned, a
picturesque figure it must be admitted, until the boss of the job came
along, overruling the good-hearted workmen and ordering Hervey
from those delightful precincts of dirt and disorder. Ejections of this
sort were nothing new to Hervey.
At luncheon Mr. Walton was so casual and friendly in his talk that
the boy more than ever conceived himself to be on probation. There
were no threats, no warnings. But somehow he felt that his next
transgression would be followed by vigorous consequences. This
seemed to be in the home atmosphere.
In the afternoon he wandered forth and was lucky in seeing a
special bus parked near the station. Along the side of it was a
canvas sign that read:
FARRELTON BASEBALL TEAM
JUNIOR BUSINESS MEN’S ASSOCIATION
He lost no time in making inquiries of the waiting driver and, on
learning that the young business men’s team was to play the
Hanniford team at Farrelton Junction grounds, he asked if he might
join the imposing caravan.
“Guess they’ll have a full load, sonny,” said the driver. “The band’s
going and a lot of the merchants.”
“Well, my father’s a merchant,” said Hervey.
“Anybody from your father’s place playing?”
It was suggestive that the rather old-fashioned establishment of
conservative Mr. Walton was not represented on this gala occasion.
The team was made up of young men who were clerks in the
Farrelton stores and the band also was part of this young business
men’s organization. They were having a half holiday to beat the
Hanniford team. Wistful boys stood gazing at the special bus; some,
no doubt, would hike to Farrelton Junction. Hervey alone sought
acceptance into this merry adult company.
“Don’t I know Mr. Holmes? Don’t I get ice cream in his store?” he
demanded. “Do you bet he won’t let me get in? Do you dare me to
get in now?”
“Come ahead in,” called a burly young fellow in the bus. He was
resplendent in a gray baseball suit with F.B.T. on it. “Come on, I dare
you to.”
In went Hervey and down into a seat and the burly young fellow’s
arm was around his shoulder.
“Do you take it back?” Hervey demanded.
“What?”
“The dare; do you take it back?”
“Where did you come by that hat?” the ball player asked. “So you
want to root for the J.B.M.A. huh? All right, youngster.”
You see how it was with Hervey? Other boys, standing enviously
outside, could only stare aghast. Then one ventured to try Hervey’s
method and failed utterly. And there you are.
Soon the bus was crowded with ball players, business men, and
the band. Hervey was the only boy. It started off with a deafening
Sousa march leaving the stay-at-homes cheering.
In the mellow evening of that same day the bus returned bringing
a load somewhat less exuberant, for Hanniford beat the Farrelton
team eleven to one.
That one, however, was a home run. And it is with this home run
that we are now concerned.
CHAPTER XVII
OVER THE TOP
There probably was never a boy in the world who rendered so
much gratuitous service to his elders as Hervey Willetts. It was not
exactly the spirit of service that impelled him. Next to being alone he
liked to be mixed up in the manual activities of men and he was wont
to constitute himself a sort of utility boy in their labors. Whenever the
red wrecking car from the Mohawk Garage arrived upon the scene of
a smashup, you would be pretty sure to see Hervey perched upon
the seat with the mechanic. His boast that he knew the firemen was
well made; he had many times been allowed to ride to fires on the
bellowing apparatus. To paraphrase the familiar song Hervey had no
rights at all, but he got there just the same.
Exactly why he preferred to loll out in the field chasing the balls
which escaped the fielders, rather than to pitch or catch on a
younger boys’ team, I do not know. He could not get a very good
view of the game from his self chosen and remote post. But so it
was, he sprawled out there during the whole progress of the game,
occasionally running after the fugitive ball, which the players seemed
willing enough to let him do.
At intervals, as the spirit moved him, he encouraged caterpillars to
walk onto a stick, then dexterously projected them to a selected spot.
He seemed captivated by this novel form of outdoor sport. Once a
caterpillar alighted on his head and it was quite a stunt without the
aid of sight to lay the stick in just the right spot for the caterpillar to
proceed upon it. He missed several balls doing this, but no one
seemed to care. His contribution to the game was quite voluntary.
Suddenly came the home run, knocked by the young man who
was teller in the Farrelton Trust Company. At that moment the score
stood three to nothing in favor of Hanniford. Amid frantic cheering
the ball sped over the heads of the outfielders, over Hervey’s head—
over a fence even— a fence which no aspiring ball had ventured to
sail over in many a long month. And around went the runner, amid
deafening yells, past first, past second, past third—and home. It was
a spectacular run.
Pell-mell after the ball went Hervey. Before he had reached the
fence the pitcher was fondling another ball; there was to be no
interruption on account of a lost ball, but if he wished to go after it
they would be glad to have it back. Up the high iron fence he
scrambled, slipping, straining and catching his trousers on the
ornamental pickets. He stood between pickets, balancing himself. If
he didn’t jump he would fall. And he had better take care that one or
other of his feet did not get caught between those ornamental
arrowheads when he did jump. He swayed, swung his arms to get
his balance, and jumped. But he was afraid to give a springing jump
for fear his feet would catch in the narrow space between those
gilded arrowheads.
So he did not jump clear of the trim row of hydrangea bushes
which bordered the fence within. Instead he went sprawling down
into it and a shower of snowy flakes from the huge flowers
besprinkled his clothing and floated away on the air. For a few
seconds he literally swam in the yielding bushes, scattering the flaky
petals as he trod down the gorgeous clusters. “When you see those
things you know school is going to open,” Roy Blakeley of Temple
Camp had told him.
But now something even more tragic was going to happen. For a
few moments his sprawling legs did not even find the ground. Then
one landed on the damp earth underneath the spreading shrubs and
he strode out opening and tearing the flowered branches by main
strength. He emerged in the very teeth of a huge dog that had run up
barking furiously. In sheer self-protection, he backed into the
shrubbery and damaged it still more, the dog advancing menacingly,
the while barking with increasing excitement. The beast seemed in a
very delirium of rage.
Intent as the dog was on challenging Hervey’s progress, the
safest course seemed to be to mount the fence again. In having
recourse to this retreat he trampled the bushes still more till he had
made a sorry wreck of them. The dog’s frantic barking increased till
he seemed beside himself with wrath. What might have happened if
he had remained master of the situation it would be harrowing to
describe, he was deterred from further aggression by a bulky,
youngish man in a pair of overalls who came briskly along a flower-
bordered walk and dragged him by the collar, then gave him a kick.
He was quite as brisk and vigorous with Hervey as he had been
with the dog, reaching across the bushes, grabbing him by the collar,
and hauling him out into the path where he continued holding him in
a firm grip.
“You let me go,” said Hervey, his anger rising with this indignity.
“I’m not going to beat it, but you let me go. You needn’t think I’m like
a dog, you big⸺ You let me go, do you hear!” He accompanied his
demand with a vigorous kick in his captor’s shins.
“What are you doing in here?” the young man demanded angrily.
“Do you see what you did. I suppose you’re the youngster that was
in here last night after grapes.” He held his captive at arm’s length,
though indeed Hervey did not repeat the vicious assault with his feet.
“I came in after the ball,” he said.
“Yes, and did you see the sign out there as big as a house, or are
you blind?”
It was quite like Hervey that he had seen no sign; he seldom saw
them.
“Look at what you’ve done,” said his captor. “How much damage
do you suppose you’ve done there? Look at that. Look at that other
bush. Look at those two there. You’d think an earthquake had struck
them. Do you think you can do fifty or a hundred dollars’ worth of
damage to get a baseball? What do you think of this?” he added,
turning to another man who had just appeared. The man shook his
head dubiously. “Well, he’s going to learn his lesson this time.”
“It’s the first time I was ever in here,” said Hervey fearfully.
“And it will be the last,” said his captor. “You heard what the
governor told me before he left, Jake, that I should have the law on
any more trespassers? I’m expected to run this place, look after fifty
acres—cows, horses, poultry, and oversee three acres of this fancy
stuff—and look at it! Who got blamed about the rhododendrons—you
remember? I’ve got to be superintendent and detective and
everything else here. Go get Charlie and tell him to come and fix
these things up. You’d think a cyclone hit them.”
“I didn’t mean⸺” Hervey began.
“Oh, I know,” the man snapped. “You didn’t know private property
has to be respected. Well, I’m going to do what I was told to do, then
maybe you’ll learn a lesson. Every time anybody comes over that
fence he lands on my head, it seems. I’m the one to get the blame.
You go get Charlie; I’ll take care of this kid.”
If Hervey had not been too fearful to think he might have surmised
that the anger of this man, evidently superintendent of a large estate,
had not been aroused simply by this particular instance of trespass,
even with its destructive accompaniment. The man had evidently
been harassed by trespassers on the one hand and by his employer
on the other. Hervey had precipitated himself into those beautiful
gardens at a most unpropitious time. He was evidently to be the
terrible example to others who had made free in those fruited and
flowered precincts.
“All right, sir; you come along with me,” said the superintendent
briskly.
CHAPTER XVIII
GUILTY
“Can’t you take me to the man that owns this place?” poor Hervey
asked, as his captor strode along, holding him by the sleeve.
“I’d have to take you all the way to Europe to do that,” the man
answered with a kind of brisk pleasantry. “Switzerland and gosh
knows where all. And all I got is two men on the grounds.”
The unfortunate captive ventured to take advantage of this faint
sign of relenting. “If I promise never to⸺”
“You promise that to the man I’m going to take you to,” the
superintendent interrupted. “I’ve got nothing to do with it.” He
seemed not a bad sort, but rather a man keyed up to perform a plain
duty. “I was on the grill, now it’s your turn,” he said. “I’ve got the
harvests to get ready for and grading down the terraces and it seems
I’ve got to look out for every grape-stealing fence climber in the
state.”
Hervey tried another tack with this much-harassed man who
talked shop so freely with him. “Bimbo, I feel sorry for you,” he said.
The man glanced sideways at him. “Well, I reckon nobody’s going
to kill you,” he said.
He hurried along winding gravel walks, Hervey running to keep up
with him. Soon they passed along the side of a great brick mansion
covered with ivy. The windows on the ground floor were boarded up.
The lawn which they crossed was shaded by mammoth elms and at
a pretty granite bird bath, a robin was leisurely taking a drink,
pausing like an epicure after each draught. Hervey wished that he
was to be taken before the owner of this princely estate; somehow
he felt that he would stand a chance with a gentleman of such
wealth. He knew that wealthy gentlemen helped the Boy Scouts. But
then he was no longer a scout....
With brisk concentration on a palpably unpleasant task the
responsible custodian of the place passed out into the road and
along it for perhaps a hundred yards where there were several
houses, a couple of stores and a square white church. This was all
there was of Farrelton Junction. Down in the woods was a tiny
railroad station. The superintendent conducted Hervey to a white
peak-roofed house almost exactly like the one he lived in. Like most
New England houses it was porchless and severe. But it looked as if
it had been painted only that very day. On the front door a modest
sign proclaimed it to be the home of Alden Snibbel, Justice of the
Peace. Hervey was relieved that this time it was not a police station
he was to enter.
Mr. Snibbel himself opened the door and immediately a delicious
odor of cooking pastry was wafted to Hervey. Mr. Snibbel was
coatless with suspenders conspicuously visible. He was lanky and
had a sandy mustache. He was in need of shaving. He was easy
and pleasant. There was no suggestion of authority or the law in the
plainly furnished room where Hervey and his captor sat down on a
hair-cloth sofa. A parrot in a cage said, “Here we are. Stay to dinner.”
Hervey felt reassured; it was not so bad. Mr. Snibbel sat down at a
flat desk and this was the only suggestion of legal formality in the
whole scene.
Best of all, Hervey’s captor addressed Mr. Snibbel by his first
name. “Sniffs pretty good, Allie,” said he.
“The wife’s making pies,” said the justice. “Get your radio fixed all
right?”
“Had to get a tube up to the Center. Well, here’s the first catch—
hook, bait and sinker. Didn’t notice the sign a mile big, sprawled
down into the flower hedge; says he was after a ball.”
The justice of the peace glanced at Hervey, then back at the
complainant.
“I’m doing just what General Pond told me to do,” said the
superintendent. “I’m bringing this youngster here for trespass. The
general gave me his orders; no matter who it was, he said.”
“Yes, he was complaining to me,” said the justice casually. He
seemed to ponder for a few moments, then asked Hervey his name,
where he lived, if he attended school, etc. And Hervey told him how
he had not intended to trespass; how he was just pursuing the ball.
He said he was sorry he had done any damage. He protested that
he had not seen the sign.
“Well, if you think he’s punished⸺” the superintendent said. It
was amusing how at the point of sentencing he seemed to waver
and relent.
“I think it just simmers down to a plain case of trespass,” the
justice drawled impersonally and not unkindly. “He didn’t intend to do
any damage. He’s responsible for that, of course, but I sort of think
that just a little taste of the law and he’ll stay out of people’s grounds;
I think then he’ll pay more attention to signs. You don’t want to make
a charge of destroying property? Just trespass—that’s unlawful
entry.”
“No, I’m not the man to pile it on.”
The justice seemed to pause and consider. Then suddenly, as if to
make an end of the matter, he said, “Well, there’s no use of property
owners putting up signs if a boy that doesn’t care enough to take
notice comes along and just goes where he wants to. And besides, a
fence around private property is sign enough. You saw the fence, I
reckon.”
“Yes sir,” said Hervey, in panic apprehension.
“Hmm. And if the authorities don’t stand ready to enforce the law,
there’s not much use of anything.” He glanced at General Pond’s
superintendent in a way of pleasant query, as if to ask whether this
was not fair and reasonable.
“Seems so,” said the superintendent.
“Well, I’m going to fine you five dollars,” said the justice. “And that
really isn’t five dollars fine, because it includes the costs. You know
what costs are? Well every time a boy breaks the law and gets
caught it costs the community money. So the boy has to pay this;
that’s only fair. Five dollars fine including costs,” he added
conclusively.
“I haven’t got five dollars,” Hervey said pitifully. “So do I have to go
to jail?”

  • 21. FOREWORD If you are reading this book, you are embarking on the road toward becoming a Cisco-certified networking engineer. Or at the least, you are contemplating the journey and are curious to know what lies ahead. It was not too many years ago that the only technical certification Cisco Systems offered—indeed, the only serious internetworking certification anyone offered—was the Cisco Certified Internetwork Expert (CCIE) certification. Acquiring the CCIE meant months of intensive study to tackle a hands-on lab, the details of which were mysterious to most. Those who passed the lab (few passed on their first or even second attempt) had lengthy hands-on experience in internetworking before even beginning their course of preparation. Only a very few intrepid individuals passed the CCIE lab without extensive prior experience. Cisco Systems has, since that time, added to their program a number of intermediate certifications that can be used as stepping stones toward the coveted CCIE. You must still, in the end, prove your expertise in the dreaded hands-on lab, but these intermediate certifications are wonderful for getting you acclimatized to the rigors of testing your skills and knowledge without having to step into the most difficult of them cold. The first milestone on the certification path is the Cisco Certified Network Associate (CCNA), the subject of Paul Browning’s outstanding preparation guide. Within these pages, Paul imparts to you the knowledge you need to pass the CCNA exam, step by step, using abundant illustrations, examples, and exercises. But beyond the coursework, in this book you will find the practical advice necessary for gaining hands-on experience and preparing for the certification exam that will benefit you not only for the CCNA but also through subsequent Cisco certifications to whatever objective you set for yourself.
  • 22. Follow the advice and exercises Paul has provided for you here and you will have made an excellent start. Jeff Doyle CCIE #1919
  • 23. ACKNOWLEDGMENTS Thanks to Paul Bokor for helping with the technical edit. INTRODUCTION TO THE 5TH EDITION I wrote the first edition of Cisco CCNA Simplified while working at Cisco TAC. My manager had just informed us that our entire department was being made redundant. All of our jobs were being outsourced to Manila in the Philippines. We were thanked for our hard work and asked to keep it up until our last day which, for some, would be in the next month. In a panic, I contacted a company I’d attended for some PC assembly training a few years earlier. I offered to run a Cisco course for the owner if he could fill it from his list of former students, and we could split the profits. Within the hour, he called back and accepted the offer. By the next week, I had a date to teach eight students the Cisco CCNA syllabus. I spent the next few weeks writing some study notes for the students to accompany the course. At that time in 2002, there was only the Cisco study guide and one from Sybex. Neither had any labs included, which shocked me. Even though the CCNA exam was theory only, surely students would want to get at least some hands- on time with routers and switches. I had a few advantages over the other publishers. I had started from the bottom, I was still working on live networks, and I was regularly teaching the material to students. I had feedback every day from people telling me what was working, what needed further explanation, and where more (or less) labs were required. I also invented my own easy subnetting method to help students answer
  • 24. any subnetting question within around 30 seconds (it’s in this book also). I eventually published the book and, to my amazement, it became an Amazon best seller. All of a sudden I was receiving messages from people all over the world from all walks of life who were using my book to pass the exam, which led to networking jobs in large corporations and even the government. For this reason, I’ve updated this study guide every time Cisco updated their exam, which is every three years, resulting in this latest version. The current CCNA Routing and Switching exam represents some of the biggest changes in many years. Cisco has reintroduced many of the networking basics they removed, such as topology types, but also added many topics that were previously at the CCNP level, such as BGP, GRE, QoS, DHCP snooping, and more. They have also added Software Defined Networking, cloud computing, and virtualization. The network engineer’s job is rapidly changing and this is reflected in the Cisco CCNA syllabus. It’s important that you review the syllabus from Cisco’s website before you take the actual exam because they reserve the right to make changes. Bear in mind that the syllabus is a guideline so they also reserve the right to ask you questions about topics not included in the syllabus. I state this because I get the occasional angry e-mail from students stating that this happened to them and blaming me. We’ve scrapped around 15% of the material from the previous version of Cisco CCNA Simplified and added around 30%, so your workload has increased as has the level of difficulty. The mini-labs were really popular so you will find a lot more in this version. If you need anything else or want more topics or labs, then visit the support page at https://www.howtonetwork.com/ccnasimplified and hit me up. Please bear in mind that it has to be relevant to the exam though. The URL above has a ton of exam support material, so please use it BEFORE you attempt the exam or you will surely fail.
  • 26. BIOGRAPHIES Paul Browning (LLB[Hons], CCNP, MCSE, A+, and Network+) spent 12 years as a police officer in Coventry and Birmingham in the UK. He left for a career in IT in June 2000 and started out working at an IT help desk. After passing his MCSE and CCNA, he got a job working at the Cisco TAC north of London, which closed in March 2003. Paul then started his IT consultancy and training company, Networks, Inc. Ltd. Since 2003, Paul has written several best-selling IT books and has trained thousands of students through his classroom and web-based IT courses. Farai Tafa, CCIE #14811 RS/SP, is an internetwork engineer with over 10 years of experience in core IP routing, LAN and WAN switching, IP telephony, and wireless LAN implementation. He
  • 27. currently holds two Cisco CCIE certifications in the Routing and Switching and the Service Provider tracks. His other certifications include CCVP, JNCIA, JNCIS, and ITILv3 Foundation. Farai lives in Dallas, Texas, with his wife and two daughters. Daniel Gheorghe is a CCIE in Routing and Switching. He is currently preparing for his second CCIE certification (in Security) and he is developing his skills in system penetration testing. He also holds numerous certifications in networking and security, from Cisco and other vendors, including CCNA, CCDA, CCNA Security, CCNP, CCDP, CCIP, FCNSA, FCNSP, and CEH. He took an interest in IT at an early age and soon developed a passion for computer networking, which made him study hard to reach the expert level. Daniel has worked for different Cisco Partners and System Integrators in Romania in system design, implementation, and troubleshooting enterprise-level networks. He is also involved in several international freelance consulting projects in his areas of expertise. Daniel is a very dynamic person, and in his spare time he likes to travel and to participate in all kinds of sports. About the Technical Reviewer

  • 29. INTRODUCTION The Problem with CCNA Study Guides I failed my first attempt at the Cisco CCNA exam. I studied four hours per day for around three months, but I was smashed in the exam and fell short of the required pass mark. With the benefit of having worked for Cisco Systems, running my IT consulting company, and then an IT training company specializing in Cisco networking, I now realize the problem. First, most Cisco manuals are written by trainers who haven’t worked on a live network for years. They moved into training years or decades ago and stayed there. As you know, IT changes quickly and if you don’t use your skills on live networks, they get rusty fast. I experienced this myself when I started teaching, which is why I decided to keep freelancing on the side and hire three top Cisco consultants who design, install, and troubleshoot enterprise networks on a daily basis to help me write this book. This inspired me to ask the technical editor, Dario, to add his comments whenever he felt he had something useful to add. It could be an important change to industry best practices, a change to default IOS commands, or even a configuration tip that you will benefit from in the real world. Keep your eyes peeled for a photo of Dario when he has something to add. “Hi, from me. I’m a Dual CCIE working on enterprise-class networks that span the globe. Because I design, install, and troubleshoot very large networks, I’ll be sharing with you some of
  • 30. the things I’ve learned to help you pass the CCNA exam and become a better network engineer.” Second, if around 60% of the CCNA exam’s final score comes from hands-on labs and troubleshooting, then where are all the labs? At most, CCNA study guides will give you a few lines of configuration to copy but this falls well short of the mark for what you need to know for the exam. In the CCNA exam, you will be asked to configure and troubleshoot complex topics, including routing, security, and switching, using the Cisco configuration commands. All this will be timed, adding even more pressure. For this reason, I’ve added 43 mini-labs that you can copy to help you understand how to configure the technologies. There are also 32 end-of-chapter full labs where you will follow my configurations of more complex protocols and services, and you will see the full router and switch configurations as well. I’ve also included advanced labs that you will find particularly challenging. These advanced labs feature multiple layers of routing, security, and protocols that would test any CCNA-level engineer to his or her limits. Cisco CCNA Simplified versus Cisco CCNA in 60 Days I seem to be best known for my Cisco CCNA in 60 Days study system, but that was, in fact, the seventh Cisco study guide I’d written. I had no idea that when I printed the book, it would become an international best-seller. It was used by many thousands of students and Cisco trainers for years, but when Cisco added one of its three yearly updates to the exam, I decided to replace Cisco CCNA Simplified with another study guide called Cisco CCNA in 60 Days. I figured that breaking everything down into daily study tasks, exams,
  • 31. and hands-on labs was a far better solution, and the results were amazing. Every week I hear from students who tell me that they’ve finally passed the exam after wasting months or even years trying other methods. But over time, I also heard from other students—busy parents who were raising young families and people who were working long hours or had other time constraints simply couldn’t put in the two hours per day required by the Cisco CCNA in 60 Days study system. I realized that there needed to be an equally effective but somewhat less intense study method. For this reason, I decided to do a complete rewrite of Cisco CCNA Simplified, not only to update it with all the latest exam topics but also to improve on the entire study experience based on what I’ve learned over the last 15 years in the IT industry that really works for students. This is an entirely new and different book from Cisco CCNA in 60 Days, so you are best off using just one of these two study methods. If you’ve bought this book (as opposed to reading a sample or browsing through it at a book store), then stick with this book and find another CCNA manual to use for reference if you need one. Free Bonus Material I’ve learned so much since publishing my first Cisco study guide. One of the main lessons is that even with hundreds of proofreadings and technical edits, mistakes still creep in. Even the mighty Cisco Press is often heavily criticized for having a large number of errors in their manuals. For this reason, I’ve added free bonus website access. On the URL below, you will find: Errata End-of-chapter interactive exams Bonus labs (with solutions) Bonus exams Other study goodies https://www.howtonetwork.com/ccnasimplified
  • 32. This gives me an easy way to ensure that I plug any gaps in the learning that you get from the study guide, as well as save on the size of the manual, which would be over 1,000 pages if I added all the extra bonus goodies here. I also have an older website for the old version of the CCNA exam. Around 70% of the content is still relevant for the current exam, but because I’ve updated it all I made it free access. Just bear in mind that it doesn’t match the current exam syllabus but, nonetheless, it has a lot of useful videos, exams, and labs. It’s at www.howtonetwork.com. Cisco CCNA Simplified Video Course All you need to pass your CCNA exam is this book, the free online exams you get access to, and hands-on time with some form of Cisco rack. I will go into more detail on your rack options in the “How to Do the Labs” section below. I also run an online IT certification website called https://www.howtonetwork.com/ccnasimplified, where I’ve added a video training course to accompany this study guide. Membership also includes access to over 30 other IT training courses and two live Cisco racks. For those of you who are just about to jump over to Amazon to kick me for “selling” stuff, I want to make it clear that you DO NOT NEED the video course. It’s there for anyone who prefers lectures as a learning style. Unfortunately, I have to make a small charge for access to cover the thousands of gigabytes of streaming video costs and the hosting and power costs of the live Cisco racks and web hosting, but it works out to be just 66 cents per day ($20 a month). Just to be clear once again, you don’t need to use the video course to pass the exam, so if money is tight, you are all set with what you already have. Reviews

I bet it was sent in while you were standing up at the corner watching where he went—I bet you.” “Gee, some bets!” said Craig. “I bet that in a couple of days or so, or in a week maybe, they’ll arrest somebody for that robbery and I bet Chesty McCullen will admit it was the one that told him to send in the alarm.” “I bet you he won’t,” Hervey shouted. “I bet you he will,” Craig shouted. Hervey was aroused to high excitement. Ordinarily he was too amiable, or perhaps too little interested in such matters, to get into disputes with other boys. He was for action rather than argument. He was too free and easy to quibble. And as for scouting, he was the last one to be discussing its nice points with scouts in good standing. He was not aroused about any such matter now. He was thinking of poor little Chesty McCullen and trying to square himself with Chesty by vigorously defending him. “You’re a couple of tin-horn scouts,” he shouted. “Such swell detectives, you get your names in the papers catching criminals and everything, you make me laugh! If anybody rings the fire-alarm the whistle will blow inside of one minute. You even admit it didn’t blow for maybe ten minutes. How do you know what happened in those ten minutes. Could you watch where Chesty was going and watch that fire-box too? You’d have to have eyes in the back of your head and you haven’t even got eyes in the front of your head!” “Listen, Herve,” said Craig, becoming serious and very friendly; “cut it out; what’s the use scrapping? The cops said what we did was all right. Why don’t you be a scout yourself? You never come to meetings, you never go round with us, you never chip in, you don’t bother about merit badges or anything—gee! Now when Warner and I do something like scouts are supposed to do, you come around and jump all over us. What are you sore about, anyway? We saw Chesty there, and we saw him run when he heard us, and we went to the police station and told about it. Jiminy crinkums, what are you so sore about, Hervey?” Ah, that was it! What was he so sore about? This young free lance who did not take any interest in the concerns and doings of other
  • 35. boys. Why all this pother? And what was the matter with these two good-natured scouts who had been content to camp on the Lewis lawn while Hervey Willetts was driving the management to distraction up at Temple Camp? They were pretty good scouts. Suddenly, Hervey must descend upon them with technicalities and storming denunciation. What was he so sore about? “I never knew you took so much interest,” said Warner Lewis. “Will you stay and help us cook lunch? We’ve got some spaghetti.” “Do you say it wasn’t mean to get that kid arrested?” Hervey demanded. “We didn’t get him arrested, we only went and told what we saw,” said Craig. “Any one would think he was your brother.” “He let me use his father’s boat,” Hervey said. “If I stay and eat with you will you go with me to-night and the three of us will set him free? I know how we can do, I’ll show you! all we need is a rope.” Craig and Warner laughed heartily. “Come out of it, Herve,” Warner said. “All right!” thundered Hervey. “I’ll show you who’s a real scout! I’ll show you how to track a feller! I’ll show you how to get your name in the papers!” “I don’t see what you’re so sore about?” repeated Craig. “I’ll show you how to make a noise like a scout!” Hervey fairly yelled. “Go ahead, now you’re talking,” said Warner. “I’ll do more than talk,” Hervey screamed at him. “I can—I told my father whatever a scout can do, I can beat him at it! I can do anything that any scout in any troop can do, and then I can take him out and lose him!” “Goodness me,” said Warner. “I’ll smash your little stunt for you—you see,” said Hervey with gleaming eyes. “Do you dare me to? Do you dare me to? Do you say I can’t set Chesty McCullen free—do you dare me?” “There you go with your dares,” said Craig. “Do you dare me to; do you say I can’t?” Hervey demanded with a steely look.
  • 36. “Yes, we dare you to, and we say you can’t, and we say you’re a fool,” said Warner. “I’ll make a noise like a scout for you!” shouted Hervey. That was pretty good. It would be hard to analyze Hervey’s impulses in all his boastful excitement, and to say whether he was sore at those two boys or sore at himself. He himself hardly knew what was the matter with him. But he was going to trample those two boys in the dust and make a noise like a scout. Not for a moment did he admit that he was going to hit the scout trail with a vengeance and cleanse his own soul of a yellow stain that was upon it.
  • 37. CHAPTER XIV AT THE BAR “If you fool around that jail, you’re crazy and you’ll get yourself in trouble,” Craig called after him. “I’ll free him,” shouted Hervey. “I’ll have everybody in town laughing at you—a couple of half-baked detectives! You must have been reading Young Sleuth, the Boy Detective. I’ll show you.” “You’re a fool, Herve,” was the last he heard. It was odd how, even at his best and on the right trail, he must work differently from other boys and quite alone. He might have sought the advice and co-operation of these good scout comrades. But he must make them out worse than himself and leave them astonished and bewildered. He must get things all askew in his mind and conjure an honorable act into a sort of stunt. The throwing down of a dare! He could not just do the right thing for its own sake. Yet he could not bear the lashings of his own conscience. We can only follow in his trail and see where it leads. And it leads through strange and devious ways, I promise you. In this episode of his story it led to a good destination—the police station. There was nothing contrite or remorseful about him as he faced the elevated desk at which the sergeant sat facing him. The frowning officer gazed down upon him and took in at a glance the brown face, the dancing, daredevil, gray eyes, the huge hole in his stocking. He fixed a quizzical look of scrutiny on the rimless hat, Hervey’s most treasured and original possession, which seemed to set him apart from all other boys on the face of the earth, embodying as it did the very essence of the bizarre. The sergeant leaned forward and read with interest the largest tin button on that perforated felt crown—Be good and you’ll be happy, and another which said Keep smiling.
  • 38. “You better take your hat off,” he said. Hervey took off his hat. “Well, young feller, what’s troubling you?” “I came to tell you that I’m the one who turned in that false alarm,” said Hervey. “I did it because a feller that I met dared me to. Maybe he was a burglar, but anyhow you got to prove it to me first. Maybe the police are only fools thinking he’s a burglar. Those two scouts are a couple of fools because they admit they were up at the corner and they didn’t even see me, they’re such punk scouts. I can show you my own tracks in the field. So you better let Chesty McCullen go home, because he didn’t do it.” “Go easy, young feller,” warned the officer, “you’re puttin’ too many fools in your talk. So you sent in the alarm, huh? What’s your name?” The chief strolled in, leaned against the desk and listened while Hervey told the story of his encounter with the stranger who had thought up the hot tamale stunt. Then this scout who was no scout, or this happy-go-lucky boy who was one (suit yourself) was held on the charge of malicious mischief. “So that’s what you call a hot tamale, is it?” the sergeant asked. “It’s a hot tamale,” said the chief. It was not clear whether he was characterizing the stunt or the fact of Hervey’s coming and giving himself up. That was a pretty good hot tamale. The chief was in about the same uncomfortable predicament that Councilor Wainwright was in when he dismissed Hervey from Temple Camp. But like Councilor Wainwright he had his duty to perform. So Hervey was held on the charge of malicious mischief and they called up Walton’s Stationery Store and told poor Mr. Walton about it. And meanwhile, they liberated little Chesty McCullen and told him that he had better not loiter around on corners and near fire boxes. He went scuffling home where his poor, scrawny, overworked mother was relieved to learn that her elder son, absent from home, was no longer wanted. Thus Chesty McCullen got a sort of a backwash from scouting; he was later to be borne upon its rising tide. Poor Mr. Walton hurried to the station, a lanky, elderly man with a troubled countenance. They knew him and respected him. He was
  • 39. more troubled than Hervey, for Hervey was triumphant, whereas Mr. Walton was just humiliated. “Well, Hervey,” was all he said. “He came and told us of his own accord,” said the chief. “He’s a little devil, but a white one.” Mr. Walton nodded. “They’re so smart, not; thinking they can send a feller to jail,” said Hervey. “They dared me that I couldn’t set him free, so who’s got the laugh?” Mr. Walton did not have the laugh, at all events. He listened soberly as they told him that Hervey would have to be taken before the recorder for proper disposition of the case. Such things get around like wildfire and even before the little party with the culprit had started for the recorder’s court, a couple of reporters were upon the scene, scenting perhaps some move in the more important end of the case. Instead of a burglar they saw only a rather bewildered boy as the center of attraction. And they listened and made the most of it as Hervey gave a description of the stranger for whom he had performed. It may be told now that that stranger was never found; nor was it ever proven that Hervey had played the dupe and all unconsciously been an accessory to a major crime. As for his own excursion in the dangerous field of malicious mischief, he was lucky as he always claimed to be. Poor Mr. and Mrs. Walton suffered more keenly than he. “Of course this kind of thing can’t be tolerated,” said the recorder. “Tampering with the public emergency apparatus is a serious business.” Hervey had never supposed that he had done that. He knew he had sent in a false alarm. But “tampering with the public emergency apparatus”—that sounded pretty big. It had been even a greater stunt than he had supposed. Mr. Walton could only stand and listen. The recorder was a young lawyer and liked to hear himself talk and see people hang with suspense upon his words. Let no one say that the law is no respecter of persons. Poor Chesty McCullen would have been fined for this offense and his father would not have been able to pay the fine and Chesty would have spent a week or two in jail. He owed more to Hervey than to the law.
  • 40. “I think,” the recorder said, addressing Hervey, “that you have had a good lesson. I think you realize the seriousness of what you did.” (He was never more mistaken in his life.) “I think you are sufficiently punished,” he added. “Those fellers are punished too,” said Hervey. “But if you are ever brought here again,” the recorder continued, “this affair will be remembered and it will go hard with you.” He glanced significantly at Mr. Walton, as if to say that he thought a little warning of that sort was a good thing. “Now young man, you go home and look out who you make friends with and don’t try to show off.” He did Hervey an injustice there, for most of our hero’s exploits were performed when he was quite alone and he never “showed off.” If that were all there were to it, it would be easy to comprehend him. Out of his mortification Mr. Walton, always fair, must say one last word. “I think, your Honor, that it is to his credit that he came here and gave himself up just when his safety seemed assured. I’m not quite sure about his motive, but I suppose we ought to judge people by their acts and get at their motives that way.” “I’d rather you’d try to work out his motives than I,” smiled the young judge. And Mr. Walton bowed acknowledgment. He said not one single word to Hervey except to lay his hand on the boy’s shoulder as they left the place. Perhaps it meant that he was pleased that in the big essentials his stepson had not been tried and found wanting. But he seemed disheartened and if Hervey had been approachable through the channels of sentiment, he would have felt a little twinge as this plain, kindly man went off down the street, back to his stationery store.
  • 41. CHAPTER XV CHESTY, AMBASSADOR There was time enough that afternoon for Hervey to stage the climax of the latest dare. He wished to do this before the evening paper appeared. It was not by way of showing off, but according to the ethics of dares and stunts the performer must always report and confound his challenger. It is amusing how punctilious Hervey was in such matters. He was probably the only boy in the upper world of Farrelton who knew where to find Chesty McCullen. But Farrelton had an underworld too, a sprawling group of hovels down by the river, and here Chesty lived. The neighborhood was one of Hervey’s familiar haunts. Chesty, now thoroughly aroused to the perils of Farrelton, could not have been dragged there by wild horses, but for Hervey he would do anything. “I set you free,” said Hervey, “so you have to pay me back. You have to go up to New Street and see Warner Lewis and Craig Hobson and tell them I sent you. You must only just say to them that they dared me I could get you out of jail so now they got their answer. Seeing is believing, you tell them that. You’ll see a tent on the lawn of one of those houses near the fire-alarm box; that’s where they are. And you can tell them they’re a couple of sap-headed fools and they can take their scout troop and go to blazes with it. You just tell them that. You say I sent you because seeing is believing and they get their faces washed with their own dare.” Chesty did not know about this errand, undertaken so soon upon his release from jail. But he could not refuse Hervey and he had not the wit to inquire why his hero did not deliver this high-handed address in person. It may be assumed that Hervey had his reasons;
  • 42. perhaps he thought that the effect would be better with himself withdrawn from the scene. He was on time for supper that evening and did not venture to absent himself afterward. Instead he waited for the talk which all through the meal he suspected his father was reserving for a quiet session in the living room. “Now, Hervey,” said Mr. Walton, “this matter is closed. You did right to go and give yourself up—I don’t want to hear your reasons. What you did was right. And I think that you did it because you couldn’t get comfortable till you did. So we won’t give too much credit to your dare or your stunt or whatever it was. I⸺” “Just the same I’ll never do anything for the scouts,” Hervey flared up. “I’m through with that bunch for good and all. They got Chesty McCullen in jail; one of those fellers is a monitor in school, so that shows you what kind of a feller he is. Nix on that outfit. I’m going perch fishing with Chesty to-morrow and I’m going to blow him to a soda too. He’s a poor kid and look what he got—some deal, I’ll say. That kid can beat any of that bunch swimming.” Mr. Walton listened soberly, his lips pursed. “But you see if you hadn’t sent in the false alarm, Chesty wouldn’t have got in trouble. You got him out, but you also got him in. Isn’t that so, Herve?” “I never squealed; no siree, I never did that.” “Well, the matter is closed now anyway, Herve,” Mr. Walton said, despairingly. “I’m sorry you’re dropping out of the Scouts. But of course, I’d rather you’d drop out altogether than be a scout slacker. So you’ll just have to suit yourself. Now what I want to say to you is this. You mustn’t get into trouble again. Last year you caused us a great deal of worry and I sent you up to Temple Camp thinking you’d find a suitable field of enjoyment there. So far I haven’t heard you say one word about your summer at Temple Camp. In the spring you encouraged Mr. Allerton’s dog to follow you for miles and he got run over and I had to settle with Mr. Allerton. You got in trouble for some absurdities last Hallowe’en, taking furniture from porches. “Now you heard the judge say that if you ever came before him again, it would go hard with you. I just want to tell you, Herve, that in such a case you can’t count on me; you’ll have to take the
  • 43. consequences. I don’t mean that I’d let you go to jail; I know you wouldn’t commit a crime—be dishonest. But if it should ever seem advisable to send you away to some sort of military or training school, perhaps, where you will be under rigid discipline I would not discourage such a course. There are places where they send boys who are hard to manage. I think school opens a week from Monday, doesn’t it?” “Yop, but Hairpin Wilkens isn’t going to teach mathematics this year, that’s one good thing.” “And you’ve left the Scouts?” “I threw them down flat,” said Hervey. “But, one thing, I’m going to show Chesty McCullen a good time; look what he was up against— oh bimbo!” “I think that’s a good idea, Herve,” said Mr. Walton. “Why don’t you take him to the movies? Isn’t there a cowboy play at the Lyric?” “Nix on looking at that stuff; it only makes me want to get out on a mustang. That’s what I want to do most of all—ride a horse, a good wild one. Montana, that’s where I’d like to go. Don’t you think the train robbers are all dead—they’re not.” “No, I don’t suppose so.” “I want to go on a ranch, that’s what I want to do.” “Yes, but even on a ranch you’d have to obey orders. Ranches are run by rules. The whole world is run by rules, Herve.” “Some punk rules, I’ll say.” “Either you’ve got to do the world’s way, or else you’ve got to make the world do your way—and I’m afraid you can’t do that. Isn’t that so, Herve?” “Bet your life,” said Hervey. “Well, you take Chesty out and give him a good time; I think that’s a fine idea.” “Sure, after being in jail like that,” said Hervey. The very idea of imprisonment was terrible to Hervey. To be confined, kept in; it was horrible, unbearable. He was the grand champion of freedom.
  • 44. CHAPTER XVI TO PASTURES NEW The next morning Hervey went hunting for Chesty McCullen. He explored the neighborhood of Chesty’s wretched home and was finally driven to make inquiry at the very portals. He had never been squeamish about the character of his companions nor the scenes into which his casual acquaintanceships led him. But he could not fail to notice the squalid environment which was so different from that of his own home. He never thought of anything he did in the light of a good turn (that would be to pay a tribute to the Scouts), but he was going to show Chesty McCullen a good time and “blow him to soda,” because Chesty had been the unhappy victim of scout bungling. But Chesty was not to be found. His poor, scrawny mother, busy with the washings that she took in and exhaling an odor of soap suds, told Hervey that he had gone away early, she didn’t know where. She thought he might have gone to bring home a “washing”, but she corrected this supposition on seeing his ramshackle cart in the yard. Hervey himself had often seen this outlandish vehicle on its two wobbly wheels. It was so inseparable from its maker and owner that it even looked strange standing in the cluttered back yard quite apart from its motive power. Hervey had never seen it at home before; poor Chesty was always pushing it around town with “washings” or miscellaneous kindling wood piled into it. He went away disappointed, not knowing what to do. He had (in his own view) outlawed himself from the Scouts, and on the other hand he could not venture forth on any adventurous escapade. He knew that for a while he had better walk the straight and narrow path, and not get into any kind of trouble. His stepfather had been considerate with him, but just the same he sensed a certain something in Mr. Walton’s demeanor which boded ill for any bizarre
  • 45. and illicit enterprises. It seemed to him that his stepfather had resolved to let this little matter of the fire-alarm dare pass and to concentrate his anger and action on the next venture. There was something ominous in his very leniency, which Hervey had not failed accurately to construe. That morning he occupied a place on the swinging crane of a steam shovel that was relentlessly digging an excavation for a new building on the business thoroughfare. He continued so enthroned, a picturesque figure it must be admitted, until the boss of the job came along, overruling the good-hearted workmen and ordering Hervey from those delightful precincts of dirt and disorder. Ejections of this sort were nothing new to Hervey. At luncheon Mr. Walton was so casual and friendly in his talk that the boy more than ever conceived himself to be on probation. There were no threats, no warnings. But somehow he felt that his next transgression would be followed by vigorous consequences. This seemed to be in the home atmosphere. In the afternoon he wandered forth and was lucky in seeing a special bus parked near the station. Along the side of it was a canvas sign that read: FARRELTON BASEBALL TEAM JUNIOR BUSINESS MEN’S ASSOCIATION He lost no time in making inquiries of the waiting driver and, on learning that the young business men’s team was to play the Hanniford team at Farrelton Junction grounds, he asked if he might join the imposing caravan. “Guess they’ll have a full load, sonny,” said the driver. “The band’s going and a lot of the merchants.” “Well, my father’s a merchant,” said Hervey. “Anybody from your father’s place playing?” It was suggestive that the rather old-fashioned establishment of conservative Mr. Walton was not represented on this gala occasion. The team was made up of young men who were clerks in the Farrelton stores and the band also was part of this young business men’s organization. They were having a half holiday to beat the Hanniford team. Wistful boys stood gazing at the special bus; some,
  • 46. no doubt, would hike to Farrelton Junction. Hervey alone sought acceptance into this merry adult company. “Don’t I know Mr. Holmes? Don’t I get ice cream in his store?” he demanded. “Do you bet he won’t let me get in? Do you dare me to get in now?” “Come ahead in,” called a burly young fellow in the bus. He was resplendent in a gray baseball suit with F.B.T. on it. “Come on, I dare you to.” In went Hervey and down into a seat and the burly young fellow’s arm was around his shoulder. “Do you take it back?” Hervey demanded. “What?” “The dare; do you take it back?” “Where did you come by that hat?” the ball player asked. “So you want to root for the J.B.M.A. huh? All right, youngster.” You see how it was with Hervey? Other boys, standing enviously outside, could only stare aghast. Then one ventured to try Hervey’s method and failed utterly. And there you are. Soon the bus was crowded with ball players, business men, and the band. Hervey was the only boy. It started off with a deafening Sousa march leaving the stay-at-homes cheering. In the mellow evening of that same day the bus returned bringing a load somewhat less exuberant, for Hanniford beat the Farrelton team eleven to one. That one, however, was a home run. And it is with this home run that we are now concerned.
  • 47. CHAPTER XVII OVER THE TOP There probably was never a boy in the world who rendered so much gratuitous service to his elders as Hervey Willetts. It was not exactly the spirit of service that impelled him. Next to being alone he liked to be mixed up in the manual activities of men and he was wont to constitute himself a sort of utility boy in their labors. Whenever the red wrecking car from the Mohawk Garage arrived upon the scene of a smashup, you would be pretty sure to see Hervey perched upon the seat with the mechanic. His boast that he knew the firemen was well made; he had many times been allowed to ride to fires on the bellowing apparatus. To paraphrase the familiar song Hervey had no rights at all, but he got there just the same. Exactly why he preferred to loll out in the field chasing the balls which escaped the fielders, rather than to pitch or catch on a younger boys’ team, I do not know. He could not get a very good view of the game from his self chosen and remote post. But so it was, he sprawled out there during the whole progress of the game, occasionally running after the fugitive ball, which the players seemed willing enough to let him do. At intervals, as the spirit moved him, he encouraged caterpillars to walk onto a stick, then dexterously projected them to a selected spot. He seemed captivated by this novel form of outdoor sport. Once a caterpillar alighted on his head and it was quite a stunt without the aid of sight to lay the stick in just the right spot for the caterpillar to proceed upon it. He missed several balls doing this, but no one seemed to care. His contribution to the game was quite voluntary. Suddenly came the home run, knocked by the young man who was teller in the Farrelton Trust Company. At that moment the score stood three to nothing in favor of Hanniford. Amid frantic cheering
  • 48. the ball sped over the heads of the outfielders, over Hervey’s head— over a fence even— a fence which no aspiring ball had ventured to sail over in many a long month. And around went the runner, amid deafening yells, past first, past second, past third—and home. It was a spectacular run. Pell-mell after the ball went Hervey. Before he had reached the fence the pitcher was fondling another ball; there was to be no interruption on account of a lost ball, but if he wished to go after it they would be glad to have it back. Up the high iron fence he scrambled, slipping, straining and catching his trousers on the ornamental pickets. He stood between pickets, balancing himself. If he didn’t jump he would fall. And he had better take care that one or other of his feet did not get caught between those ornamental arrowheads when he did jump. He swayed, swung his arms to get his balance, and jumped. But he was afraid to give a springing jump for fear his feet would catch in the narrow space between those gilded arrowheads. So he did not jump clear of the trim row of hydrangea bushes which bordered the fence within. Instead he went sprawling down into it and a shower of snowy flakes from the huge flowers besprinkled his clothing and floated away on the air. For a few seconds he literally swam in the yielding bushes, scattering the flaky petals as he trod down the gorgeous clusters. “When you see those things you know school is going to open,” Roy Blakeley of Temple Camp had told him. But now something even more tragic was going to happen. For a few moments his sprawling legs did not even find the ground. Then one landed on the damp earth underneath the spreading shrubs and he strode out opening and tearing the flowered branches by main strength. He emerged in the very teeth of a huge dog that had run up barking furiously. In sheer self-protection, he backed into the shrubbery and damaged it still more, the dog advancing menacingly, the while barking with increasing excitement. The beast seemed in a very delirium of rage. Intent as the dog was on challenging Hervey’s progress, the safest course seemed to be to mount the fence again. In having recourse to this retreat he trampled the bushes still more till he had
  • 49. made a sorry wreck of them. The dog’s frantic barking increased till he seemed beside himself with wrath. What might have happened if he had remained master of the situation it would be harrowing to describe, he was deterred from further aggression by a bulky, youngish man in a pair of overalls who came briskly along a flower- bordered walk and dragged him by the collar, then gave him a kick. He was quite as brisk and vigorous with Hervey as he had been with the dog, reaching across the bushes, grabbing him by the collar, and hauling him out into the path where he continued holding him in a firm grip. “You let me go,” said Hervey, his anger rising with this indignity. “I’m not going to beat it, but you let me go. You needn’t think I’m like a dog, you big⸺ You let me go, do you hear!” He accompanied his demand with a vigorous kick in his captor’s shins. “What are you doing in here?” the young man demanded angrily. “Do you see what you did. I suppose you’re the youngster that was in here last night after grapes.” He held his captive at arm’s length, though indeed Hervey did not repeat the vicious assault with his feet. “I came in after the ball,” he said. “Yes, and did you see the sign out there as big as a house, or are you blind?” It was quite like Hervey that he had seen no sign; he seldom saw them. “Look at what you’ve done,” said his captor. “How much damage do you suppose you’ve done there? Look at that. Look at that other bush. Look at those two there. You’d think an earthquake had struck them. Do you think you can do fifty or a hundred dollars’ worth of damage to get a baseball? What do you think of this?” he added, turning to another man who had just appeared. The man shook his head dubiously. “Well, he’s going to learn his lesson this time.” “It’s the first time I was ever in here,” said Hervey fearfully. “And it will be the last,” said his captor. “You heard what the governor told me before he left, Jake, that I should have the law on any more trespassers? I’m expected to run this place, look after fifty acres—cows, horses, poultry, and oversee three acres of this fancy stuff—and look at it! Who got blamed about the rhododendrons—you
  • 50. remember? I’ve got to be superintendent and detective and everything else here. Go get Charlie and tell him to come and fix these things up. You’d think a cyclone hit them.” “I didn’t mean⸺” Hervey began. “Oh, I know,” the man snapped. “You didn’t know private property has to be respected. Well, I’m going to do what I was told to do, then maybe you’ll learn a lesson. Every time anybody comes over that fence he lands on my head, it seems. I’m the one to get the blame. You go get Charlie; I’ll take care of this kid.” If Hervey had not been too fearful to think he might have surmised that the anger of this man, evidently superintendent of a large estate, had not been aroused simply by this particular instance of trespass, even with its destructive accompaniment. The man had evidently been harassed by trespassers on the one hand and by his employer on the other. Hervey had precipitated himself into those beautiful gardens at a most unpropitious time. He was evidently to be the terrible example to others who had made free in those fruited and flowered precincts. “All right, sir; you come along with me,” said the superintendent briskly.
  • 51. CHAPTER XVIII GUILTY “Can’t you take me to the man that owns this place?” poor Hervey asked, as his captor strode along, holding him by the sleeve. “I’d have to take you all the way to Europe to do that,” the man answered with a kind of brisk pleasantry. “Switzerland and gosh knows where all. And all I got is two men on the grounds.” The unfortunate captive ventured to take advantage of this faint sign of relenting. “If I promise never to⸺” “You promise that to the man I’m going to take you to,” the superintendent interrupted. “I’ve got nothing to do with it.” He seemed not a bad sort, but rather a man keyed up to perform a plain duty. “I was on the grill, now it’s your turn,” he said. “I’ve got the harvests to get ready for and grading down the terraces and it seems I’ve got to look out for every grape-stealing fence climber in the state.” Hervey tried another tack with this much-harassed man who talked shop so freely with him. “Bimbo, I feel sorry for you,” he said. The man glanced sideways at him. “Well, I reckon nobody’s going to kill you,” he said. He hurried along winding gravel walks, Hervey running to keep up with him. Soon they passed along the side of a great brick mansion covered with ivy. The windows on the ground floor were boarded up. The lawn which they crossed was shaded by mammoth elms and at a pretty granite bird bath, a robin was leisurely taking a drink, pausing like an epicure after each draught. Hervey wished that he was to be taken before the owner of this princely estate; somehow he felt that he would stand a chance with a gentleman of such wealth. He knew that wealthy gentlemen helped the Boy Scouts. But then he was no longer a scout....
  • 52. With brisk concentration on a palpably unpleasant task the responsible custodian of the place passed out into the road and along it for perhaps a hundred yards where there were several houses, a couple of stores and a square white church. This was all there was of Farrelton Junction. Down in the woods was a tiny railroad station. The superintendent conducted Hervey to a white peak-roofed house almost exactly like the one he lived in. Like most New England houses it was porchless and severe. But it looked as if it had been painted only that very day. On the front door a modest sign proclaimed it to be the home of Alden Snibbel, Justice of the Peace. Hervey was relieved that this time it was not a police station he was to enter. Mr. Snibbel himself opened the door and immediately a delicious odor of cooking pastry was wafted to Hervey. Mr. Snibbel was coatless with suspenders conspicuously visible. He was lanky and had a sandy mustache. He was in need of shaving. He was easy and pleasant. There was no suggestion of authority or the law in the plainly furnished room where Hervey and his captor sat down on a hair-cloth sofa. A parrot in a cage said, “Here we are. Stay to dinner.” Hervey felt reassured; it was not so bad. Mr. Snibbel sat down at a flat desk and this was the only suggestion of legal formality in the whole scene. Best of all, Hervey’s captor addressed Mr. Snibbel by his first name. “Sniffs pretty good, Allie,” said he. “The wife’s making pies,” said the justice. “Get your radio fixed all right?” “Had to get a tube up to the Center. Well, here’s the first catch— hook, bait and sinker. Didn’t notice the sign a mile big, sprawled down into the flower hedge; says he was after a ball.” The justice of the peace glanced at Hervey, then back at the complainant. “I’m doing just what General Pond told me to do,” said the superintendent. “I’m bringing this youngster here for trespass. The general gave me his orders; no matter who it was, he said.” “Yes, he was complaining to me,” said the justice casually. He seemed to ponder for a few moments, then asked Hervey his name,
  • 53. where he lived, if he attended school, etc. And Hervey told him how he had not intended to trespass; how he was just pursuing the ball. He said he was sorry he had done any damage. He protested that he had not seen the sign. “Well, if you think he’s punished⸺” the superintendent said. It was amusing how at the point of sentencing he seemed to waver and relent. “I think it just simmers down to a plain case of trespass,” the justice drawled impersonally and not unkindly. “He didn’t intend to do any damage. He’s responsible for that, of course, but I sort of think that just a little taste of the law and he’ll stay out of people’s grounds; I think then he’ll pay more attention to signs. You don’t want to make a charge of destroying property? Just trespass—that’s unlawful entry.” “No, I’m not the man to pile it on.” The justice seemed to pause and consider. Then suddenly, as if to make an end of the matter, he said, “Well, there’s no use of property owners putting up signs if a boy that doesn’t care enough to take notice comes along and just goes where he wants to. And besides, a fence around private property is sign enough. You saw the fence, I reckon.” “Yes sir,” said Hervey, in panic apprehension. “Hmm. And if the authorities don’t stand ready to enforce the law, there’s not much use of anything.” He glanced at General Pond’s superintendent in a way of pleasant query, as if to ask whether this was not fair and reasonable. “Seems so,” said the superintendent. “Well, I’m going to fine you five dollars,” said the justice. “And that really isn’t five dollars fine, because it includes the costs. You know what costs are? Well every time a boy breaks the law and gets caught it costs the community money. So the boy has to pay this; that’s only fair. Five dollars fine including costs,” he added conclusively. “I haven’t got five dollars,” Hervey said pitifully. “So do I have to go to jail?”
