d-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 dome-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
[Page 178]
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
th
