CHAPTER IV

TRACKS, TRAILING AND SIGNALING

_By Ernest Thompson Seton, Chief Scout_

"I wish I could go West and join the Indians so that I should have no

lessons to learn," said an unhappy small boy who could discover no

atom of sense or purpose in any one of the three R's.

"You never made a greater mistake," said the scribe. "For the young

Indians have many hard lessons from their earliest day--hard lessons

and hard punishments. With them the dread penalty of failure is 'go

hungry till you win,' and no harder task have they than their reading

lesson. Not twenty-six characters are to be learned in this exercise,

but one thousand; not clear straight print are they, but dim,

washed-out, crooked traces; not in-doors on comfortable chairs, with a

patient teacher always near, but out in the forest, often alone and in

every kind of weather, they slowly decipher their letters and read

sentences of the oldest writing on earth--a style so old that the

hieroglyphs of Egypt, the cylinders of Nippur, and the drawings of the

cave men are as things of to-day in comparison--the one universal

script--the tracks in the dust, mud, or snow.

"These are the inscriptions that every hunter must learn to read

infallibly, and be they strong or faint, straight or crooked, simple

or overwritten with many a puzzling, diverse phrase, he must decipher

and follow them swiftly, unerringly if there is to be a successful

ending to the hunt which provides his daily food.

"This is the reading lesson of the young Indians, and it is a style

that will never become out of date. The naturalist also must acquire

some measure of proficiency in the ancient art. Its usefulness is

unending to the student of wild life; without it he would know little

of the people of the wood."

There Are Still Many Wild Animals

It is a remarkable fact that there are always more wild animals about

than any but the expert has an idea of. For {188} example, there are,

within twenty miles of New York City, fully fifty different kinds--not

counting birds, reptiles, or fishes--one quarter of which at least are

abundant. Or more particularly within the limits of Greater New York

there are at least a dozen species of wild beasts, half of which are

quite common.

"Then how is it that we never see any?" is the first question of the

incredulous. The answer is: Long ago the beasts learned the dire

lesson--man is our worst enemy; shun him at any price. And the

simplest way to do this is to come out only at night. Man is a daytime

creature; he is blind in the soft half-light that most beasts prefer.

While many animals have always limited their activity to the hours of

twilight and gloom, there are not a few that moved about in daytime,

but have given up that portion of their working day in order to avoid

the arch enemy.

Thus they can flourish under our noses and eat at our tables, without

our knowledge or consent. They come and go at will, and the world

knows nothing of them; their presence might long go unsuspected but

for one thing, well known to the hunter, the trapper, and the

naturalist: wherever the wild four-foot goes, it leaves behind a

record of its visit, its name, the direction whence it came, the time,

the thing it did or tried to do, with the time and direction of

departure. These it puts down in the ancient script. Each of these

dotted lines, called the trail, is a wonderful, unfinished record of

the creature's life during the time it made the same, and it needs

only the patient work of the naturalist to decipher that record and

from it learn much about the animal that made it, without that animal

ever having been seen.

Savages are more skilful at it than civilized folk, because tracking

is their serious life-long pursuit and they do not injure their eyes

with books. Intelligence is important here as elsewhere, yet it is a

remarkable fact that the lowest race of mankind, the Australian

blacks, are reputed to be by far the best trackers; not only are their

eyes and attention developed and disciplined, but they have retained

much of the scent power that civilized man has lost, and can follow a

fresh track, partly at least by smell.

It is hard to over-value the powers of the clever tracker. To him the

trail of each animal is not a mere series of similar footprints; it is

an accurate account of the creature's life, habit, changing whims, and

emotions during the portion of life whose record is in view. These are

indeed autobiographical chapters, {190} and differ from other

autobiographies in this--they cannot tell a lie. We may get wrong

information from them, but it is our fault if we do; we misread the

document that cannot falsify.

When to Learn Tracking

The ideal time for tracking, and almost the only time for most folk,

is when the ground is white. After the first snow the student walks

forth and begins at once to realize the wonders of the trail. A score

of creatures of whose existence, maybe, he did not know, are now

revealed about him, and the reading of their autographs becomes easy.

It is when the snow is on the ground, indeed, that we take our

four-foot census of the woods. How often we learn with surprise from

the telltale white that a fox was around our hen house last night, a

mink is living even now under the wood pile, and a deer--yes! there is

no mistaking its sharp-pointed un-sheep-like footprint--has wandered

into our woods from the farther wilds.

Never lose the chance of the first snow if you wish to become a

trailer. Nevertheless, remember that the first morning after a night's

snow fall is not so good as the second. Most creatures "lie up" during

the storm; the snow hides the tracks of those that do go forth; and

some actually go into a "cold sleep" for a day or two after a heavy

downfall. But a calm, mild night following a storm is sure to offer

abundant and ideal opportunity for beginning the study of the trail.

How to Learn

Here are some of the important facts to keep in view, when you set

forth to master the rudiments:

_First_.--No two animals leave the same trail; not only each kind but

each individual, and each individual at each stage of its life, leaves

a trail as distinctive as the creature's appearance, and it is obvious

that in that they differ among themselves just as we do, because the

young know their mothers, the mothers know their young, and the old

ones know their mates, when scent is clearly out of the question.

Another simple evidence of this is the well known fact that no two

human beings have the same thumb mark; all living creatures have

corresponding peculiarities, and all use these parts in making the

trail.

_Second_.--The trail was begun at the birthplace of that creature and

ends only at its death place; it may be recorded in visible track or

perceptible odor. It may last but a few {191} hours, and may be too

faint even for an expert with present equipment to follow, but

evidently the trail is made, wherever the creature journeys afoot.

_Third_.--It varies with every important change of impulse, action, or

emotion.

_Fourth_--When we find a trail we may rest assured that, if living, the

creature that made it is at the other end. And if one can follow, it

is only a question of time before coming up with that animal. And be

sure of its direction before setting out; many a novice has lost much

time by going backward on the trail.

_Fifth_.--In studying trails one must always keep probabilities in mind.

Sometimes one kind of track looks much like another; then the question

is, "Which is the likeliest in this place."

If I saw a jaguar track in India, I should know it was made by a

leopard. If I found a leopard in Colorado, I should be sure I had

found the mark of a cougar or mountain lion. A wolf track on Broadway

would doubtless be the doing of a very large dog, and a St. Bernard's

footmark in the Rockies, twenty miles from anywhere, would most likely

turn out to be the happen-so imprint of a gray wolf's foot. To be sure

of the marks, then, one should know all the animals that belong to the

neighborhood.

These facts are well known to every hunter. Most savages are hunters,

and one of the early lessons of the Indian boy is to know the tracks

of the different beasts about him. These are the letters of the old,

old writing.

A First Try

Let us go forth into the woods in one of the North-eastern states when

there is a good tracking snow, and learn a few of these letters of the

wood alphabet.

Two at least are sure to be seen--the track of the blarina and of the

deer mouse. They are shown on the same scale in Figs. 1 and 2, page

198.

In Fig. 3 is the track of the meadow mouse. This is not unlike that of

the blarina, because it walks, being a ground animal, while the deer

mouse more often bounds. The delicate lace traceries of the masked

shrew, shown in Fig. 4, are almost invisible unless the sun be low;

they are difficult to draw, and impossible to photograph or cast

satisfactorily but the sketch gives enough to recognize them by.

The meadow mouse belongs to the rank grass in the lowland {192} near

the brook, and passing it toward the open, running, water we may see

the curious track of the muskrat; its five-toed hind foot, its

four-toed front foot, and its long keeled tail, are plainly on record.

When he goes slowly the tail mark is nearly straight; when he goes

fast it is wavy in proportion to his pace. Page 193.

The muskrat is a valiant beast; he never dies without fighting to the

last, but he is in dread of another brookland creature whose trail is

here--the mink. Individual tracks of this animal are shown in No. 1,

page 161. Here he was bounding; the forefeet are together, the

hindfeet track ahead, and tail mark shows, and but four toes in each

track, though the creature has five on each foot. He is a dreaded

enemy of poor Molly Cottontail, and more than once I have seen the

records of his relentless pursuit. One of these fits in admirably as

an illustration of our present study.

A Story of the Trail

It was in the winter of 1900, I was standing with my brother, a

business man, on Goat Island, Niagara, when he remarked, "How is it?

You and I have been in the same parts of America for twenty years, yet

I never see any of the curious sides of animal life that you are

continually coming across."

"Largely because you do not study tracks," was the reply. "Look at

your feet now. There is a whole history to be read."

"I see some marks," he replied, "that might have been made by some

animal." "That is the track of a cottontail," was the answer. "Now,

let us read the chapter of his life. See, he went in a general

straight course as though making some well-known haunt, his easy pace,

with eight or ten inches between each set of tracks, shows unalarm.

But see here, joining on, is something else."

"So there is. Another cottontail."

"Not at all, this new track is smaller, the forefeet are more or less

paired, showing that the creature can climb a tree; there is a

suggestion of toe pads and there is a mark telling evidently of a long

tail; these things combined with the size and the place identify it

clearly. This is the trail of a mink. See! he has also found the

rabbit track, and finding it fresh, he followed it. His bounds are

lengthened now, but the rabbit's are not, showing that the latter was

unconscious of the pursuit."

After one hundred yards the double trail led us to a great pile of

wood, and into this both went. Having followed his {193} game into

dense cover, the trailer's first business was to make sure that it did

not go out the other side. We went carefully around the pile; there

were no tracks leading out.

"Now," I said, "if you will take the trouble to move that wood pile

you will find in it the remains of the rabbit half devoured and the

mink himself. At this moment he is no doubt curled up asleep."

As the pile was large and the conclusion more or less self-evident, my

brother was content to accept my reading of the episode.

What About Winter Sleepers

Although so much is to be read in the wintry white, we cannot now make

a full account of all the woodland four-foots, for there are some

kinds that do not come out on the snow; they sleep more or less all

winter.

{194}

Thus, one rarely sees the track of a chipmunk or woodchuck in truly

wintry weather; and never, so far as I know, have the trails of

jumping mouse or mud turtle been seen in the snow. These we can track

only in the mud or dust. Such trails cannot be followed as far as

those in the snow, simply because the mud and dust do not cover the

whole country, but they are usually as clear and in some respects more

easy of record.

How to Make Pictures of Tracks

It is a most fascinating amusement to learn some creature's way of

life by following its fresh track for hours in good snow. I never miss

such a chance. If I cannot find a fresh track, I take a stale one,

knowing that, theoretically, it is fresher at every step, and from

practical experience that it always brings one to some track that is

fresh.

How often I have wished for a perfect means of transferring these wild

life tales to paper or otherwise making a permanent collection. My

earliest attempts were in free-hand drawing, which answers, but has

this great disadvantage--it is a translation, a record discolored by

an intervening personality, and the value of the result is likely to

be limited by one's own knowledge at the time.

Casting in plaster was another means attempted; but not one track in

ten thousand is fit to cast. Nearly all are blemished and imperfect in

some way, and the most abundant--those in snow--cannot be cast at

all.

Then I tried spreading plastic wax where the beasts would walk on it,

in pathways or before dens. How they did scoff! The simplest ground

squirrel knew too much to venture on my waxen snare; around 'it, or if

hemmed in, over it, with a mighty bound they went; but never a track

did I so secure.

Photography naturally suggested itself, but the difficulties proved as

great as unexpected, almost as great as in casting. Not one track in

one thousand is fit to photograph; the essential details are almost

always left out. You must have open sunlight, and even when the

weather is perfect there are practically but two times each day when

it is possible--in mid-morning and mid-afternoon, when the sun is high

enough for clear photographs and low enough to cast a shadow in the

faint track.

The Coon that Showed Me How

Then a new method was suggested in an unexpected way. A friend of mine

had a pet coon which he kept in a cage in his bachelor quarters up

town. One day, during my friend's {195} absence the coon got loose and

set about a series of long-deferred exploring expeditions, beginning

with the bachelor's bedroom. The first promising object was a writing

desk. Mounting by a chair the coon examined several uninteresting

books and papers, and then noticed higher up a large stone bottle. He

had several times found pleasurable stuff in bottles, so he went for

it. The cork was lightly in and easily disposed of, but the smell was

far from inviting, for it was merely a quart of ink. Determined to

leave no stone unturned, however, the coon upset the ink to taste and

try. Alas! it tasted even worse than it smelt; it was an utter failure

as a beverage.

And the coon, pushing it contemptuously away, turned to a pile of fine

hand-made, deckle-edge, heraldry note-paper--the pride of my friend's

heart--and when he raised his inky little paws there were left on the

paper some beautiful black prints. This was a new idea: the coon tried

it again and again. But the ink held out longer than the paper, so

that the fur-clad painter worked over sundry books, and the adjoining

walls, while the ink, dribbling over everything, formed a great pool

below the desk. Something attracted the artist's attention, causing

him to jump down. He landed in the pool of ink, making it splash in

all directions; some of the black splotches reached the white

counterpane of the bachelor's bed. Another happy idea: the coon now

leaped on the bed, racing around as long as the ink on his feet gave

results. As he paused to rest, or perhaps to see if any places had

been neglected, the door opened, and in came the landlady. The scene

which followed was too painful for description; no one present enjoyed

it. My friend was sent for to come and take his coon out of there

forever. He came and took him away, I suppose "forever." He had only

one other place for him--his office and there it was I made the

animal's acquaintance and heard of his exploit--an ink and paper, if

not a literary affair.

This gave me the hint at the Zoo I needed, a plan to make an authentic

record of animal tracks. Armed with printer's ink and paper rolls I

set about gathering a dictionary collection of imprints.

After many failures and much experiment, better methods were devised.

A number of improvements were made by my wife; one was the

substitution of black paint for printer's ink, as the latter dries too

quickly; another was the padding of the paper, which should be light

and soft for very light animals, and stronger and harder for the

heavy. Printing from a mouse, for example, is much like printing a

delicate {196} etching; ink, paper, dampness, etc., must be exactly

right, and furthermore, you have this handicap--you cannot regulate

the pressure. This is, of course, strictly a Zoo method. All attempts

to secure black prints from wild animals have been total failures. The

paper, the smell of paint, etc., are enough to keep the wild things

away.

In the Zoo we spread the black pad and the white paper in a narrow,

temporary lane, and one by one drove, or tried to drive, the captives

over them, securing a series of tracks that are life-size, properly

spaced, absolutely authentic, and capable of yielding more facts as

the observer learns more about the subject.

As related here, all this sounds quite easy. But no one has any idea

how cross, crooked, and contrary a creature can be, until he wishes it

to repeat for him some ordinary things that it has hitherto done

hourly. Some of them balked at the paint, some at the paper, some made

a leap to clear all, and thereby wrecked the entire apparatus. Some

would begin very well, but rush back when half-way over, so as to

destroy the print already made, and in most cases the calmest,

steadiest, tamest of beasts became utterly wild, erratic, and

unmanageable when approached with tracklogical intent.

Trying It on the Cat

Even domestic animals are difficult. A tame cat that was highly

trained to do anything a cat could do, was selected as promising for a

black track study, and her owner's two boys volunteered to get all the

cat tracks I needed. They put down a long roll of paper in a hall,

painted pussy's feet black, and proceeded to chase her up and down.

Her docility banished under the strain. She raced madly about, leaving

long, useless splashes of black; then, leaping to a fanlight, she

escaped up stairs to take refuge among the snowy draperies. After

which the boys' troubles began.

Drawing is Mostly Used

These, however, are mere by-accidents and illustrate the many

practical difficulties. After these had been conquered with patience

and ingenuity, there could be no doubt of the value of the prints.

They are the best of records for size, spacing, and detail, but fail

in giving incidents of wild life, or the landscape surroundings. The

drawings, as already seen, are best for a long series and for faint

features; in fact, the {197} drawings alone can give everything you

can perceive; but they fail in authentic size and detail.

Photography has this great advantage--it gives the surroundings, the

essential landscape and setting, and, therefore, the local reason for

any changes of action on the part of the animal; also the aesthetic

beauties of its records are unique, and will help to keep the method

in a high place.

Thus each of the three means may be successful in a different way, and

the best, most nearly perfect alphabet of the woods, would include all

three, and consist of a drawing, a pedoscript and a photograph of each

track, and a trail; i.e., a single footprint, and the long series of

each animal.

My practice has been to use all whenever I could, but still I find

free-hand drawing is the one of the most practical application. When I

get a photograph I treasure it as an adjunct to the sketch.

A Story of the Trail

To illustrate the relative value as records, of sketch and photograph,

I give a track that I drew from nature, but which could not at any

place have been photographed. This was made in February 15, 1885, near

Toronto. It is really a condensation of the facts, as the trail is

shortened where uninteresting. Page 189, No. 2.

At A, I found a round place about 5 x 8 inches, where a cottontail had

crouched during the light snowfall. At B he had leaped out and sat

looking around; the small prints in front were made by his forefeet,

the two long ones by his hind feet, and farther back is a little

dimple made by the tail, showing that he was sitting on it. Something

alarmed him, causing him to dart out at full speed toward C and D, and

now a remarkable change is to be seen: the marks made by the front

feet are behind the large marks made by the hind feet, because the

rabbit overreaches each time; the hind feet track ahead of the front

feet; the faster he goes, the farther ahead those hind feet get; and

what would happen if he multiplied his speed by ten I really cannot

imagine. This overreach of the hind feet takes place in most bounding

animals.

Now the cottontail began a series of the most extraordinary leaps and

dodgings (D,E,F.) as though trying to escape from some enemy. But what

enemy? There were no other tracks. I began to think the rabbit was

crazy--was flying from an imaginary foe--that possibly I was on the

trail of a March hare. But at G I found for the first time some spots

of blood. {198} This told me that the rabbit was in real danger but

gave no due to its source. I wondered if a weasel were clinging to its

neck. A few yards farther, at H, I found more blood. Twenty yards

more, at I, for the first time on each side of the rabbit trail, were

the obvious marks of a pair of broad, strong wings. Oho! now I knew

the mystery of the cottontail running from a foe that left no track.

He was pursued by an eagle, a hawk, or an owl. A few yards farther and

I found the remains (J) of the cottontail partly devoured. This put

the eagle out of the question; an eagle would have carried the rabbit

off boldly. A hawk or an owl then was the assassin. I looked for

something to decide which, and close by the remains found the peculiar

two-paired track of an owl. A hawk's track would have been as K, while

the owl nearly always sets its feet in the ground {199} with two toes

forward and two toes back. But which owl? There were at least three in

the valley that might be blamed. I looked for more proof and got it on

the near-by sapling--one small feather, downy, as are all owl

feathers, and bearing three broad bars, telling me plainly that a

barred owl had been there lately, and that, therefore, he was almost

certainly the slayer of the cottontail. As I busied myself making

notes, what should come flying up the valley but the owl himself--back

to the very place of the crime, intent on completing his meal no

doubt. He alighted on a branch ten feet above my head and just over

the rabbit remains, and sat there muttering in his throat.

The proof in this case was purely circumstantial, but I think that we

can come to only one conclusion; that the evidence of the track in the

snow was complete and convincing.

{198}

[Illustration: TRACKS; 1. Blarina in snow; 2. Deermouse; 3. Meadow

mouse; 4. Masked shrew.]

{199 continued}

Meadow Mouse

The meadow mouse autograph (page 189) illustrates the black-track

method. At first these dots look inconsequent and fortuitous, but a

careful examination shows that the creature had four toes with claws

on the forefeet, and five on the hind, which is evidence, though not

conclusive, that it was a rodent; the absence of tail marks shows that

the tail was short or wanting; the tubercules on each palm show to

what group of mice the creature belongs. The alternation of the track

shows that it was a ground-animal, not a tree-climber; the spacing

shows the shortness of the legs; their size determines the size of the

creature. Thus we come near to reconstructing the animal from its

tracks, and see how by the help of these studies, we can get much

light on the by-gone animals whose only monuments are tracks in the

sedimentary rocks about us--rocks that, when they received these

imprints, were the muddy margin of these long-gone creatures' haunts.

What the Trail Gives--The Secrets of the Woods

There is yet another feature of trail study that gives it exceptional

value--it is an account of the creature pursuing its ordinary life. If

you succeeded in getting a glimpse of a fox or a hare in the woods,

the chances are a hundred to one that it was aware of your presence

first. They are much cleverer than we are at this sort of thing, and

if they do not actually sight or sense you, they observe, and are

warned by the action of some other creature that did sense us, and so

cease their occupations to steal away or hide. But the snow story will

{201} tell of the life that the animal ordinarily leads--its method of

searching for food, its kind of food, the help it gets from its

friends, or sometimes from its rivals--and thus offers an insight into

its home ways that is scarcely to be attained in any other way.

The trailer has the key to a new storehouse of Nature's secrets,

another of the Sybilline books is opened to his view; his fairy

godmother has, indeed, conferred on him a wonderful {202} gift in opening

his eyes to the foot-writing of the trail. It is like giving sight to

the blind man, like the rolling away of fogs from a mountain view, and

the trailer comes closer than others to the heart of the woods.

Dowered with a precious power is he,

He drinks where others sipped,

And wild things write their lives for him

To Signal with Flag or Torch Wig-Wag

There is but one position and three motions.

The first position is with the flag or other appliance held

vertically, the signalman facing squarely toward the station with

which it is desired to communicate.

{206}

The first motion ("one" or "1") is to the right of the sender and will

embrace an arc of 90 degrees, starting with the vertical and returning

to it, and will be made in a plane at right angle to the line

connecting the two stations.

The second motion ("two" or "2") is a similar motion to the left of

the sender.

The third motion ("front," "three" or "3") is downward, directly in

front of the sender, and instantly returned upward to the first

position.

Numbers which occur in the body of a message must be spelled out in

full. Numerals may be used in signaling between stations having naval

books, using the code calls. To break or stop the signals from the

sending station, make with the flag or other signal 12 12 12

continuously.

To Send a Message

To call a station signal its letter until acknowledged; if the call

letter be not known, signal "E" until acknowledged. To acknowledge a

call, signal "1 understand," followed by the call letter of the

acknowledging station.

Make a slight pause after each letter and also after "front." If the

sender discovers that he has made an error he should make 3 followed

by 12 123, after which he begins the word in which the error occurred.

The Semaphore Signal Code

The scout may learn the correct angles at which to hold the flags from

the diagram. The easiest method of learning the alphabet is by

grouping the various letters together as follows:

For all letters from A to G, one arm only is used, making a quarter of

a circle for each letter in succession.

The letters from H to N (except J)--the right arm stands at A while

the left moves round the circle for the other letters.

For O to S, the right arm stands at B--the left arm moves round as

before.

For T, U, Y and the "annul," the right arm stands at C, the left

moving to the next point of the circle successively.

The numerical sign J (or alphabetical sign) and V--the right arm

stands at position for letter D the left arm only being moved.

{207}

W and X--the left arm stands at position for letter E, the right in

this case moving down 45 degrees to show letter X.

For the letter Z, the left arm stands at the position G--the right arm

crosses the breast taking the position F.

[Illustration: Semaphore code. (tr)]

{208}

The letters A to I also stand for the figures 1 to 9 (K standing for

0), if you make the numerical sign to show that you are going to send

numbers followed by the alphabetical sign (J) when the figures are

finished. They will be checked by being repeated back by the receiving

station. Should figures be wrongly repeated by the receiving station

the sending station will send the "annul" sign (which is answered by

the same sign) and then send the group of figures again.

The sender must always face the station to which he is sending. On a

word failing to make sense, the writer down will say, "no," when the

reader will at once stop the sending station by raising both arms

horizontally to their full extent (letter R). This demand for

repetition the sending station will acknowledge by making J. The

signaller receiving the message will then send the last word he has

read correctly, upon which the sender will continue the message from

that word.

Whistle Signs

1. One long blast means "Silence," "Alert," "Look out for my next

signal." Also approaching a station.

2. Two short blasts means "All right."

3. A succession of long, slow blasts means "Go out," "Get farther

away," or "Advance," "Extend," "Scatter."

4. A succession of short, sharp blasts means "Rally," "Close in,"

"Come together," "Fall in," "Danger," "Alarm."

5. Three short blasts followed by one long one from scout master calls

up the patrol leaders--i.e., "Leaders, come here."

Any whistle signal must be instantly obeyed at the double--as fast as

you can run--no matter what other job you may be doing at the time.

Hand or Flag Signals

Hand signals, which can also be made by patrol leaders with their

patrol flags when necessary:

Hand waved several times across the face from side to side or flag

waved horizontally, from side to side opposite the face, means "No,"

"Never mind," "As you were."

Hand or flag held high, and waved as though pushing forward, at full

extent of arm, or whistle a succession of slow blasts means "Extend,"

"Go farther out," "Scatter."

Hand or flag held high, and waved rapidly from side to side, at full

extent of arm, or a succession of short, quick blasts on the whistle,

means "Close in," "Rally," "Come here," "Danger," "Cattle on track."

{209}

Hand or flag pointing in any direction means "Go in that direction."

Clenched hand or flag jumped rapidly up and down several times means,

"Hurry," "Run."

The movement, pushing or beckoning, indicates whether "Hurry here" or

"Hurry there."

Hand (or flag) held straight up over head, palm forward, means "Stop,"

"Halt."

When a leader is shouting an order or message to a scout who is some

way off, the scout, if he hears what is being said, should hold up his

hand level with his head all the time. If he cannot hear, he should

stand still, making no sign. The leader will then repeat louder, or

beckon to the scout to come in nearer.

The following signals are made by a scout with his staff when he is

sent out to reconnoitre within sight of his patrol, and they have the

following meaning:

Staff held up horizontally, that is, level, with both hands above the

head, means, "I have found."

The same, out with staff moved up and down slowly, means, "I have

found, but a long way off."

The same, staff moved up and down rapidly, means, "I have found, and

close by."

The staff held straight up over the head means, "Nothing in sight."

Indian Signs and Blazes

Shaking a blanket: I want to talk to you.

Hold up a tree-branch: I want to make peace.

Hold up a weapon, means war: I am ready to fight.

Hold up a pole horizontally, with hands on it: I have found something.

[Illustration: Indian Signs and Blazes.

"I have gone home."]

WIRELESS TELEGRAPHY

_The Boy Scout Wireless Club

Y. M. C. A., Newark, N.J._

The following directions are given for an up-to-date wireless

apparatus for stationary use in the home or at the meeting place of

each patrol.

We will consider the receiving apparatus first:

[Illustration: Diagram of wireless transmitter and receiver. (tr)]

The first thing to do is to build an aerial. First find out how long

your location will allow you to build it, and how high. It ought to be

at least 50 to 60 feet high and about 70 to 100 feet long. The main

point in building an aerial is to have it {211} well insulated from

the ground, and all connections in wire perfectly solid. It is

advisable to solder every connection and to make your aerial strong as

it has a great deal to do with the working qualities of the station.

After this is completed, the inside work on instruments should begin.

1. A pair of watch-case receivers having a resistance of 1,000 ohms

each, manufactured by a reliable firm.

2. A loose coupler tuning coil of about 800 meters.

3. One of Mordock's metal detectors or one of similar design.

4. A variable condenser of about 5-10 plates.

5. A fixed condenser so arranged that its capacity can be changed if

desired.

With these instruments the receiving set is complete, so we next take

up the sending apparatus.

1. A two-inch induction coil.

2. A heavy spark gap (zinc preferable).

3. One wireless key with heavy contacts.

4. A plate condenser which can be easily made by any scout. Good glass

is the main point.

5. A triple pole, double throw aerial switch. (Can be made by scouts.)

Now you have everything necessary to go ahead and assemble your

station. The next thing is to connect them up.

Above is a diagram which will make a good station for a scout. This

station, if the aero is of the proper height, is capable of sending

messages from 8 to 10 miles.

The Receiving Set

Perhaps the most fundamentally important part of a wireless telegraph

station is the aerial. Its construction varies with each station, but

a few general suggestions may be of use.

The builder should aim to get as high and as long an aerial as

possible, height being the more important factor. In a stationary set

the aerial may be fastened to a tree or pole or high building while in

a field set a tree or an easily portable pole must be used.

The aerial itself should be made of copper wire and should be hung

between spreaders as long as convenient and insulated from them by two

cleat insulators in series at each end.

The experimenter should see that his leading-in wire is placed

conveniently and comes in contact with the walls, etc., {212} as

little as possible. All points of contact must be well insulated with

glass, porcelain, or hard rubber.

The tuning coil is very simple in construction. A cardboard tube,

about three inches in diameter, is mounted between two square heads.

This tube is wound with No. 24 insulated copper wire and very well

shellaced to avoid loosening of the wire.

Two pieces of one quarter inch square brass rod, to be fastened

between the heads, are secured, and a slider, as shown in drawing, is

made. The rods are fastened on the heads and the insulation in the

path of the slides is then well scraped off. Binding posts are then

fastened to rods and coil ends.

[Illustration: Details of instruments for field use.]

{213}

The detector, although the most important of the instruments, is

perhaps the simplest. It is constructed of a hardwood base with a

small brass plate fastened on by means of a binding post. On the other

end of the base is fastened a double binding post which holds a brass

spring, as in the drawing. On the end of this spring is fastened a

copper point made by winding a few inches of No. 36 or 40 wire on it

and allowing about three sixteenths of an inch to project. This

completes the detector but, for use in this instrument, lead sulphide

or Galena crystals must be secured.

The condenser is made of two pieces of tin-foil, four by ten, and

three pieces of waxed paper a little larger than the foil. A piece of

wire is twisted into the end of each piece of foil, and then one sheet

of foil is laid on a sheet of paper. This is then covered by another

sheet of paper upon which is laid the second sheet of foil. On top of

this is laid the third sheet of paper and the whole is folded into a

convenient bundle. The sheets of foil must be well insulated from each

other and the wires must project from the condenser.

The ground connection is made by soldering a wire to a cold water

pipe. In the case of a portable set the ground may be made by driving

a metal rod into the ground or sinking metal netting into a body of

water.

The telephone receivers cannot well be made and must therefore be

bought. The type of phones used will therefore depend entirely on the

builder's purse.

The Sending Set

The same aerial and ground are used for sending as were used for

receiving, and for the experimenter, it will be far cheaper to buy a

spark coil for his sending set than to attempt to make one.

For a field set there will be very little need of a sending helix, as

close tuning will be hardly possible; but for the stationary set this

is very useful.

The helix is made by building a drum with square heads fastened

together by six or eight uprights, arranged on the circumference of a

circle. On this then are wound ten or twelve turns of No. 10 or 12,

brass or copper wire. Binding posts are fastened to the ends of the

wire and variable contact made on the turns by means of metal spring

clips.

The spark gap is made of a hard-wood base with two uprights to which

are fastened strips of brass. Under these strips are {214} placed two

pieces of battery zincs so as to make the gap between their ends

variable. Binding posts are fastened to the strips for contact.

The sending condenser is the same as the receiving in construction,

but different in material. The dielectric is glass while the

conducting surfaces are tin-foil, arranged in a pile of alternate

sheets of glass and foil. The foil is shaped as in drawing and

alternate sheets have their lugs projecting on opposite sides, all

lugs on same side being connected together. For a one-inch coil but a

few of these plates are needed, but for higher power a greater number

are necessary.

[Illustration: Wireless Telegraph Set Designed for Boy Scouts of

America by L. Horle.]

All that now remains is the setting up of the instruments. They are

arranged as in the drawing, a double-point, {215} double-throw switch

being used to switch from sending to receiving.

After having connected up the receiving instruments, the receiver is

placed at the ear and the point of the detector placed on the various

parts of the mineral until the signals are heard clearly. Then the

tuning coil is adjusted until the signals are loudest.

The sending apparatus is set up, the key and batteries having been

bought or made, and used to call some other station. The clip is put

on various twins of the helix until the other station signals that the

signals are loudest. The station is then ready for actual operation.
