trapped for their fur, and in 1913 no less than 4,500,000 were sold in 
London. 
Back of the gray fox a group of little brown bats shows about 
a hundred of these animals gathering in Wyandotte Cave,

The woodchuck or ground hog is a vegetable feeder, but does very 
little harm to crops save clover. It hibernates for a large 
part of the year, usually from September to April. The 
old legend says that the ground hog comes out of his hole on the second 
of February, and if it is bright and he sees his shadow he 
goes back into his hole for six weeks longer and we may 
expect more cold weather. Other groups represent the 
varying hare, the jack rabbit amid the characteristic sage brush, and the 
common species of squirrels.

Pack rats, so called from their habit of packing off, carrying 
away, small articles, are characteristic of the mountain 
regions of the West, though one species is found 
near West Point.

In the center of the hall is a group showing the color phases of our 
black bear, from which it appears that in a part of its range the black 
bear is literally a white bear. 
At the end of the hall is a group of Roosevelt elk found in the Coast 
Range from British Columbia to Northern California. 
Roosevelt Elk Once abundant, they have become much reduced in 
a numbers, though an effort is now being made to preserve 
Sheep them. On the opposite side of the hall are the mountain 
sheep or bighorns. 
Nearby is a group of that interesting animal, the beaver, perhaps the 
most important of North American mammals and one 
intimately connected with the early history and explora- 
tion of this country.

On the south side of the hall are displayed some of the cloven-hoofed 
animals of North America. These include sheep, musk 
ox, caribou, collared peccary and various species of deer. 
In one of the cases is a group of antelope showing the man- 
ner in which they wander across the plains. 
: Here too are, for the time being, shown the mammals of the polar 
regions, placed in the North American hall in order that the Southeast 
Pavilion, which once harbored them, may be used as a workroom for the 
preparation of a group of African elephants and other mammals from 
the dark continent.
