CHAPTER VIII.

THE BEAVER.

When this country was first explored and settled, beavers were found

in good numbers throughout the United States and Canada, but at

present they are extinct in many of the states where they were once

abundant. Today they are found in fair numbers throughout the greater

part of Canada and Alaska, also in a few of the northern and western

states. There are also a few beavers found in the south at the

present time. However, many of the states, as well as some of the

provinces of Canada, have made laws prohibiting the trapping or

killing of beavers, to prevent them from being exterminated.

The beaver is an amphibious animal, resembling the muskrat in

appearance but much larger. It has the same thick, heavy body, short

neck and scaly tail. The hind feet are large and strong and the toes

are connected by a web; the front feet are small. The tail is "paddle

shaped," four or five inches wide and about ten inches long. When

full grown, the beaver will weigh from forty to fifty pounds,

although occasionally a much larger one is found. The under fur is

very fine and soft, and is mixed with longer and coarser hairs called

"guard hairs". The prevailing color is a rich, reddish brown, on the

back and sides, and ashy beneath.

The food of the beaver consists mostly of bark, of such woods as

poplar, birch, willow and cottonwood, as well as the roots of the

water lily. In the south they also eat corn.

Beavers build houses of sticks, stones, and mud, similar in shape to

the houses of the muskrat, locating usually, in the edge, of a pond

or lake, but often making a large pond to suit their requirements, by

building a dam across the stream. Even when their houses are built on

a lake or pond, they always build a dam across the outlet, so as to

raise the water two or three feet.

The dams are built of the same material as the houses. Sometimes

there are one or two small dams found below the main dam, and they

are so well made that they will last for many years, and are so tight

that the water usually drips evenly over the top.

The houses are also very well made, the walls being several feet in

thickness. There are usually two entrances, both under water. The

size and general shape of the house depends on the number of beavers

inhabiting it. The house of a full family of beavers will usually

measure about twelve feet in diameter at the water line, but will

some times be even larger, and the height is about six or seven feet.

When there are only two or three beavers, the house is much smaller,

and more pointed on the top.

A full family consists of from six to eight members. There are

usually two old beavers, two or three two year olds, and two or three

young. The reason for this is that the young beavers remain two years

with the parents, and as it requires several years for them to grow

their full size, there are always three sizes in a family. When they

have reached the age of two years, they start out and make a house of

their own, the beavers born the spring before, becoming the medium

size, and a new litter taking their place. By autumn, the beavers

that have left the main family have their house and dam completed and

a store of food laid up for winter.

Many of the beavers travel about through the summer, following the

streams, and return to their homes early in the fall. Sometimes, if

they are late in getting back they will have to work day and night,

in order to get sufficient food gathered for winter, before the ice

comes. This food consists of saplings and small trees, which they

gnaw off about a foot above the ground, drag into the edge of the

water, where they are cut up into pieces of different lengths, stored

away, under water in front of the house. Just how they cause this

wood to sink, remain in place under the water, is a mystery. The

beaver spends the entire winter under the ice. When he feels hungry

he goes out and gets a piece of wood, takes it into the house, eats

the bark, and takes the peeled stick out again. They repair the house

and dam each fall and they also make holes in the bank under water,

to which they can retreat in case the house is disturbed, or when

they hear a noise on the ice.

Trappers who are well acquainted with the habits of the beaver, can

make a fair estimate of the number of inmates of a house. It

sometimes happens that a pair of young beavers, or a lone beaver that

has escaped from some family which has been trapped, will locate in

an old deserted house, and then it is not such an easy matter. The

experienced trapper, however, is not likely to be fooled. He goes

along the shore and carefully examines the stumps, where the animals

have been cutting trees for food. The amount of stuff that has been

cut will show, usually; but he has still a better way of determining

whether the work was done by one or more beavers. He examines the

teeth marks on the stumps, and if they are all alike, he decides that

there is not a full family, but only two, or perhaps only one.

A lone beaver that has escaped from the trapper, is difficult to

trap. I remember once finding such a one, located on a large pool of

a fair sized stream. He had no dam and had only a small house along

the bank. I found him in the fall, while the water was still open,

and he was busy laying in a supply of food for winter. Well, I went

there one rainy day and set two traps. I set the traps very

carefully, fastening to sliding poles, which I had cut quite a

distance away so as not to make any noise near the house. The rain

washed the scent away in a short time, and I could see no reason why

he should take alarm; but he did, just the same. I kept those traps

set a week, but did not catch him, nor did I ever see any fresh signs

there, after I had set the traps. Apparently he had left the place

immediately after I had set the traps. An Indian trapper had trapped

several families of beavers, near there the season before, and this

beaver was one that had "given him the slip."

In cutting timber, the beaver takes the wood in small chips, gnawing

all around the tree, until it falls. He knows absolutely nothing

about throwing the tree in the direction in which he wishes it to

fall, but lets it fall just as it is inclined to go. I have seen

where a tree had lodged, refusing to fall, and the beaver had stood

up and cut several pieces off the butt, and as the tree still refused

to fall, he had let it remain hanging. It was a case of hard work and

no pay.

When one finds a family of beavers, and expects to trap the same

ground each season, he should not attempt to catch them all, as by

leaving a few to breed, he is sure of getting beavers each season.

The Indians, in such cases, trap the old beavers only, which they do

by setting the traps a good distance from the house, for the young

beavers never venture far away.

Many beavers are trapped in the fall just before the ice forms, but

their fur is not prime until mid-winter. In the north they remain in

good condition until the first of June; in the south they would

probably not be good after the middle of April.

Beaver castors have a market value, usually selling for seven or

eight dollars a pound. In preparing them, they should be dried

slowly, in a shady place. Most trappers prefer to keep the castors

for scent, as it is attractive to many animals. The Indians sometimes

combine the two scents by making a hole in the beaver castors, and

squeezing the contents of the oil castors into them. The castors are

then hung up and allowed to dry. This is more or less attractive to

all animals, only a small piece being used in connection with the

bait.

The best traps for beavers are the Nos. 2 1/2, 3, 3 1/2 and 4

Newhouse, the No. 4 Victor, the No. 4 Oneida Jump, and Blake & Lamb.

[Illustration: Trap Set for Beaver--Sliding Pole.]

The following methods of trapping are for use in open water, in

either the fall or spring. The first method given is usually

considered best:

Find a place where the bank bluffs a little and the water is of good

depth. Make a little pocket in the bank, several inches deep, and set

the trap in the water directly in front of this pocket, where the pan

of the trap will be about two inches under water. Take a piece of

beaver castor and fasten it to the bank with a stick, about fourteen

inches above the water, and as far back in the pocket as possible. If

you are using some other scent instead of beaver castor, just dip a

small stick in the scent and fasten it to the bank. Fasten the trap

so that the beaver will drown; the sliding pole is best. Be sure to

use a dead pole or stake, as if a green pole is used the other

beavers may carry it away, trap and all. This is a very good method

for spring and fall, or at any time when there is open water:

Here is another method for the same kind of place:

Set the trap under water at the foot of a steep bank, and fasten a

couple of green poplar or cottonwood sticks on the bank, directly

over the trap, so that the beaver will step into the trap in trying

to reach them. Have the fresh cut ends of the sticks showing plainly,

and make your set near the house or dam so that the beavers are sure

to see it. Fasten trap so that the captured animal will be sure to

drown. No covering is needed on traps when they are set under water.

Look for the beaver's slides or trails where he drags his food into

the water, and if the water is deep enough to drown him, set the trap

under about two inches of water, just where he lands on the bank.

This set is all right in the fall, when the beaver is laying in his

food for the winter, but is not much good in the spring. Some

trappers set the trap a foot or more from the shore, where the water

is about six inches deep, as by so doing the beaver is caught by the

hind foot, and is not so likely to escape. When using a set of this

kind, it is best to use a number 3 1/2 or 4 trap, as the No. 3 is too

small for the beaver's hind foot.

Beavers usually have a slide or trail over the center of the dam, and

this makes a very good place to set a trap. Set the trap under water

on the upper side of the dam, just where the trail leads over. Be

sure to fasten the trap so that the animal will drown, as if it is

not drowned, it is almost certain to escape, and even if it does not,

the others will be frightened and you will have a hard time to get

them.

In the spring, after the ice has gone, it is a good plan to set a few

traps along the stream, baiting with beaver castor, as the beavers

are traveling at this time, and you are likely to catch one almost

anywhere along the streams. When setting traps in this way, it is

best to drench the set with water to remove the human scent. The

beaver is seldom afraid of human scent, but there is likely to be an

otter along that way, and you stand a good chance of catching him in

a trap baited with beaver castor.

Beavers may be caught in mid-winter and early spring, by setting

baited traps under the ice. It is not much use to set traps under the

ice in early winter, as the beaver's food is still in good condition,

and they will not take bait well; moreover you are likely to frighten

them and make them harder to trap later on. The following methods are

among the best for use under the ice, the one first given, being most

used, and is probably the best:

Go close to the beaver's house where the ice is thin, and by cutting

small holes in the ice, find a place where the water is about twelve

inches deep. Having found such a place, enlarge the hole until it is

about sixteen by twenty inches in size, making a pen the same size as

the hole, by shoving down dead sticks about four inches apart. If the

bottom is very hard, you will have to freeze the sticks to the ice,

to hold them in place. This may be done by throwing snow in the

water, and packing it around the sticks and against the edge of the

ice. When the pen is completed, cut a piece of green poplar about 1

1/2 or 2 inches thick and two or three feet long, and fasten it to a

stake by one end--the poplar being placed at a right angle to the

stake. This green poplar is for bait, and the stake should be driven

down in one corner of the pen so that the bait is within two or three

inches from the bottom, and close along one side of the pen,

extending a foot or more beyond the entrance.

[Illustration: Beaver Trap Set Under Ice.]

The trap should be staked and set well inside of the pen, and quite

close to the bait, so that the jaw of the trap will just clear the

bait. This set will be readily understood by referring to the cut. If

the bottom is of thin mud, as is often the case, you will have to

make a bed for the trap, by sinking a bunch of evergreen boughs

inside of the pen. It is also best to fasten the bait near the

entrance to prevent the beaver from swinging it around. When the set

is completed, cover the hole with evergreen boughs, bank it with

snow, to keep it from freezing.

It is best to let this set go for about a week before looking at it.

The beavers will be frightened and will not approach the set for a

few days, but finally one of them musters up courage enough to try to

pull the bait out of the pen. When he finds it fast, he cuts it off

at the entrance of the pen, takes it to the house to eat it; this

sharpens his appetite, makes him more courageous, and he finally

ventures into the pen for the balance of the bait. In attempting to

cut the bait, he places one front foot on the bait and the other one

in the trap. When using this set you should use three or four sets at

each house.

Another good ice method is as follows: Find the proper depth of

water, about fourteen inches, and make a pen of dead sticks arranging

them in the form of a half-circle. Now take some green poplar and

shove them down firmly into the bottom, about six inches apart, close

up to the stakes, on the inside of the pen. These bait sticks must be

long enough to reach above the ice, so that they will freeze fast at

the top. Stake the trap and set it in the center of the enclosure,

with the pan about nine inches from the center bait. Throw some snow

in the hole, so that it will freeze and hold the bait sticks

securely.

The following method is one of the best for use in deep water: Cut a

dead pole about four inches in diameter and six or seven feet long.

Flatten the pole at one end, and loop the trap chain around the pole;

then set the trap on the end of the pole and tie it with a string, to

hold it in place. Now, cut an oblong hole in the ice, and place the

pole in the water in an inclined position so that the trap is about

twelve inches below the ice. Pack wet snow around the pole to hold it

in place, fasten two sticks of green poplar in the ice over the trap,

one on either side. In attempting to cut the bait, the beaver will

put his foot in the trap.

Always fasten your trap to a dead stick or pole, for if a green stake

is used, the beavers are likely to carry it away, trap and all.

Poplar and cottonwood make the best baits, but in case they cannot be

obtained, use birch, willow or black cherry.

When setting traps near the house, in open water, make as little

noise as possible, and do not remain in the vicinity longer than

necessary.

When trapping in open water, never camp or make a fire near the pond

where the beavers are located. In winter, after the ice has formed,

it does not matter.

If you find a beaver house in winter when the snow is deep, and wish

to know if it is inhabited, examine the house, and if the snow is

melted on the top, you may be sure there are beavers in it.

Another way to tell whether a house is inhabited, is to cut a hole

through the ice and shove down a piece of green poplar, filling the

hole with snow. Examine it in about a week, and if the poplar has

been cut, you may be sure you have found beavers.

The track of the beaver is seldom seen as they do not move about much

in winter and on their trails their tracks are obliterated by the

food which they drag into the water. The trapper does not look for

tracks, but for more conspicuous signs, such as houses and dams with

fresh cut wood.
