portable. As the work grew high, he supported himself on his tail, which
propped him up admirably: and he would often, after laying on one of his
building materials, sit up over against it, apparently to consider his
work, or, as the country people say, 'judge it.' This pause was
sometimes followed by changing the position of the material 'judged,'
and sometimes it was left in its place. After he had piled up his
materials in one part of the room (for he generally chose the same
place), he proceeded to wall up the space between the feet of a chest of
drawers, which stood at a little distance from it, high enough on its
legs to make the bottom a roof for him; using for this purpose dried
turf and sticks, which he laid very even, and filling up the interstices
with bits of coal, hay, cloth, or any thing he could pick up. This last
place he seemed to appropriate for his dwelling; the former work seemed
to be intended for a dam. When he had walled up the space between the
feet of the chest of drawers, he proceeded to carry in sticks, cloths,
hay, cotton, and to make a nest; and, when he had done, he would sit up
under the drawers, and comb himself with the nails of his hind feet. In
this operation, that which appeared at first to be a malformation, was
shown to be a beautiful adaptation to the necessities of the animal. The
huge webbed hind feet often turn in, so as to give the appearance of
deformities; but if the toes were straight, instead of being incurved,
the animal could not use them for the purpose of keeping its fur in
order, and cleansing it from dirt and moisture.

"Binny generally carried small and light articles between his right fore
leg and his chin, walking on the other three legs; and large masses,
which he could not grasp readily with his teeth, he pushed forwards,
leaning against them with his right fore paw and his chin. He never
carried anything on his tail, which he liked to dip in water, but he was
not fond of plunging in his whole body. If his tail was kept moist, he
