The Beaver
Categories:
STEEL TRAPS AND THE ART OF TRAPPING.
The Beaver of North America has now a world-wide reputation for
its wonderful instinct and sagacity. The general appearance of
this animal is that of a very large muskrat with a broad flattened
tail, and the habits of both these animals are in many respects
alike. The beaver is an amphibious creature and social in its habits
of living, large numbers congregating together and forming little
villages, and erecting their
ome-like huts like little Esquimaux.
The muskrat has this same propensity, but the habitation of the
beaver is on a much more extensive scale. These huts or Beaver
lodges, are generally made in rivers and brooks; although sometimes
in lakes or large ponds. They are chiefly composed of branches,
moss, grass and mud, and are large enough to accommodate a family
of five or six. The form of the lodges is dome-like, and it varies
considerably in size. The foundation is made on the bottom of the
river, and the hut is built up like a mound, often twenty feet
in diameter and projecting several feet above the surface of the
water. The walls of this structure are often five or six feet thick,
and the roofs are all finished off with a thick layer of mud laid on
with marvellous smoothness. These huts form the winter habitations
of the beavers, and as this compost of mud, grass and branches
becomes congealed into a solid mass by the severe frosts of our
northern winter, it can easily be seen that they afford a safe
shelter against any intruder and particularly the wolverine, which
is a most deadly enemy to the beaver. So hard does this frozen mass
become as to defy even the edges of iron tools, and the breaking
open of the Beaver houses is at no time an easy task. Beavers
work almost entirely in the dark; and a pond which is calm and
placid in the day time will be found in the night to be full of
life and motion, and the squealing and splashing in the water will
bear evidence of their industry. Lest the beavers should not have
a sufficient depth of water at all seasons, they are in the habit
of constructing veritable dams to ensure that result. These dams
display a wonderful amount of reason and skill, and, together with
the huts, have won for the beaver a reputation
for engineering skill which the creature truly deserves. In constructing
these ingenious dams the beavers, by the aid of their powerful teeth,
gnaw down trees sometimes of large size, and after cutting them into
smaller pieces float them on the water to the spot selected for
the embankment. In swift streams this embankment is built so as
to arch against the current, thus securing additional strength,
and evincing an instinct on the part of the animal which amounts
almost to reason. In cutting down the trees the beaver gnaws a
circular cut around the trunk, cutting deepest on the side toward
the water, thus causing the trunk to fall into the stream. The
first step in constructing the embankment is to lay the logs down
cautiously in the required line of the dam, afterwards weighting
them with heavy stones, which the beavers by their united efforts
roll upon them. The foundation of the embankment is often ten feet
in width, and is built up by continued heaping of branches, stones
and mud, until it forms a barrier of immense strength and resisting
power. In many cases, through a lapse of years, and through a
consequent accumulation of floating leaves, twigs, and seeds of plants,
these embankments become thickly covered with vegetation, and, in many
cases in the Hudson Bay country, have even been known to nurture trees
of considerable dimensions. The broad flat tail of the animal serves a
most excellent purpose, in carrying the mud to the dams or huts, and
in matting and smoothing it into a solidity.
The entrances to the various huts are all beneath the water, and
they all open into one common ditch, which is purposely dug in
the bed of the river, and is too deep to be entirely frozen. In
the summer time the huts are vacated, and the beavers make their
abode in burrows on the banks of the stream, which serve as a secure
retreat at all times, and particularly in winter when their houses
are molested. The Indians of the Northwest are aware of this fact,
and turn it to good account in the capture of the animals.
When the beaver's village is in a small creek, or brook, it is
first necessary to stake the water across both above and below
the huts. The next thing is to ascertain the exact spots of the
burrows in the banks, and when we consider the river is covered
with ice, this seems a rather difficult problem. But this is where
the Indian shows his skill. He starts upon the ice, provided with
an ice chisel secured to a long, stout handle. With this he strikes
upon the ice, following the edge of the stream. The sound of the
blow determines to his practiced ear the direct spot opposite the
opening of the burrows, and at this point a hole a foot in diameter
is made through the ice. Following the edge of the bank he continues
his search, and in like manner cuts the holes through the ice until
all the retreats are discovered. While the expert Indians are thus
engaged, the squaws are occupied in the more laborious work of
breaking open the houses, and the beavers, alarmed at the invasion of
their sanctums, make for the banks, and the ready huntsmen stationed
at the various holes, watch for their victims beneath the openings,
until a violent motion or discoloration of the water betrays their
passage beneath. The entrance to the holes in the bank are then
instantly closed with stakes and the beaver is made prisoner in
his burrow. When the depth of the burrow will admit, the arm of
the hunter is introduced, and the animal pulled out, but otherwise
a long hook lashed to a pole is employed for this purpose. Scores
of beavers are sometimes taken in this way in a few hours. Spearing
is also often successfully resorted to, and when the ice is thin
and transparent the beavers may be clearly observed as they come
to the surface, beneath the ice, for air.
The general color of the animal is reddish brown, this tint being
imparted principally by the long hairs of the fur. There is an
inner and softer down of a grey color, which lies next the skin,
and which is the valuable growth of the fur. The total length of
the animal is about three feet and a half, the flat, paddle-shaped,
scale-covered tail being about a foot in length.
The young are brought forth in April or May, from three to seven
at a litter, and take to the water when a month old. The first
four years in the beaver's life is spent under the maternal roof,
after which period they shift for themselves. To trap the beaver
successfully, requires the utmost caution, as the senses of the
animal are so keen, and he is so sagacious withal, that he will detect
the recent presence of the trapper from the slightest evidences.
The traps should be washed clean and soaked in ley, before using,
and thereafter handled with gloves, as a mere touch of the finger
will leave a scent which the acute sense of the beaver will easily
perceive. All footprints should be carefully obliterated by throwing
water upon them, and some trappers say that the mere act of spitting
on the ground in the neighborhood of the traps has been known to
thwart success.
Almost the only bait used in trapping the beaver is the preparation
called barkstone by the trappers, or castoreum in commerce.
This substance is fully described on page 150 under the head of
Scent Baits.
To the barkstone the trapper is mostly indebted for his success,
and the effect of its odor on the beaver is something surprising.
Our best trappers inform us that these animals will scent this
odor for a great distance, and will fairly squeal with delight,
not being easy until the savory bait is discovered, which almost
invariably results in capture.
Taking advantage of this curious propensity, the trapper always
carries a supply of castoreum in a closed vessel.
There are various ways of trapping the beaver, of which we shall
present the best. An examination of the river bank will easily
disclose the feeding place of the beavers, as evinced by the absence
of the bark on the branches and trunks of trees. At this spot,
in about four inches of water, set your trap, which should be a
Newhouse No. 4. Weight the end of the chain with a stone as large
as your head, and, if possible, rest it on the edge of some rock
projecting into deep water, having a smaller rope or chain leading
from the stone to the shore. A small twig, the size of your little
finger, should then be stripped of its bark, and after chewing or
mashing one end, it should be dipped in the castoreum. Insert this
stick in the mud, between the jaws of the trap, letting it project
about six inches above the water. The beaver is soon attracted by the
odor of the bait, and in reaching for it, his foot is caught in the
trap. In his fright he will immediately jump for deep water, thus
dislodging the stone, which will sink him to the bottom, and thus
drown him. The smaller chain or rope will serve as a guide to the
trap, and the victim may be drawn to the surface. Another plan is
to set the trap in about a foot of water, chaining it fast to a stout
pole securely driven in the mud further out in the stream, and
near deep water. Bait as before. The trap being thus fastened will
prevent the efforts of the animal to drag it ashore, where he would
be certain to amputate his leg and walk off. There is another method,
which is said to work excellently. The chain is secured to a very
heavy stone, and sunk in deep water, and the trap set and baited
near shore, in about a foot of water. This accomplishes the same
purpose as the pole first described, and is even surer, as the animal
will sometimes use his teeth in severing the wood, and thereby make
his escape. In the case of the stone a duplicate rope or chain
will be required to lift it in case of capture.
The trap may be set at the entrance to the holes in the banks,
two or three inches under water, implanting the stick with the
castoreum bait directly over the pan, a few inches above the water.
If the water should be deep near this spot, it is an excellent plan
to weight the end of the chain with a large stone with a leader
from it also, as already described. Insert two or three sticks in
the bank beneath the water, and rest the stone upon them.
When the beaver is caught he will turn a somersault into deep water,
at the same time dislodging the stone, which will sink him. No sooner
is a break ascertained in the dam than all the beavers unite in
fixing it, and this peculiarity of habit may be turned to account in
trapping them. Make a slight break in the dam, five inches across,
beneath the water. On the under side of the break, and of course,
on the inside of the dam, the trap should be set. The beavers will
soon discover the leak and the capture of at least one is certain.
The trap may be also set where the beavers are wont to crawl on
shore, being placed several inches below the water in such a position
that they will step on it when in the act of ascending the banks.
Where the weighted stone is not used, the sliding pole page 145
should always be employed, as it is necessary to drown the animal,
to prevent amputation and escape.
The food of the beaver consists chiefly of the bark of various
trees, together with aquatic plants. The fur is valuable only in
the late fall, winter, and early spring.
In skinning the beaver, a slit is made from the under jaw to the
vent, after which it is easily removed. It should be tacked to a flat
board, fur side in, or stretched by means of a hoop, as described
on page 275.
