The Admiralty Bear, (Ursus eulophus), represents a large 
species originally discovered on Admiralty Island, southern 
Alaska. Its dark brown color is very much like that of the 
Yakutat and Kadiak bears. 
The Grizzly Bear, or ‘‘Silver-Tip Grizzly,’’ (Ursus horri- 
bilis).—The rapid disappearance of this species from the 
United States renders all living examples of it specially 
interesting. 
Of all bears, the Silver-Tip Grizzly is the most savage and 
dangerous. He is easily angered, and when wounded or 
harried not only becomes furiously vindictive, but he also 
possesses a degree of courage which renders him a danger- 
ous antagonist. As a general thing, a Grizzly Bear, like a 
lion or tiger, will run as soon as he discovers the presence of 
his only enemy—man; but if he is wounded or cornered— 
or thinks he is cornered—he assumes the aggressive, without 
an instant’s delay. Unfortunately, the largest Silver-Tip 
Grizzlies ever killed have been too far from scales to make 
it possible to weigh them. 
The most interesting specimen of the Rocky Mountain 
Silver-Tip now on exhibition is a dark-colored and very 
handsome specimen, named ‘‘Engineer,’’ obtained in 
Meeker, Colorado, by Professor Henry F. Osborn, and pre- 
sented to the Society by the Engineers’ Club of New York 
City. The color of this individual is darker than the most 
common type of the Silver-Tip, which is sometimes almost 
as gray as a badger. 
A very beautiful male Silver-Tip, from Wyoming, is much 
lighter in color than the Colorado specimen. Its face and 
head are so light-colored it would be called by Rocky 
Mountain hunters a ‘‘Bald-Faced’’ Grizzly. A third speci- 
men was obtained for the Society at White Horse, Yukon 
Territory, in 1905, and its development will be watched with 
much interest. Throughout the Rocky Mountain region 
the ‘‘Silver-Tip’’ and the ‘‘Grizzly’’ are identical; but the 
color of the species varies considerably. 
In a wild state Grizzly Bears live on berries and fruits of 
all kinds available, succulent roots, grubs, carrion if it comes 
handy, and live game if it can be killed. In the cattle- 
growing states bordering the Rocky Mountains, owing to 
their cattle-killing propensities, a bounty of from twelve to 
fifteen dollars per head is paid for their destruction. 
The Black Bear, (Ursus americanus).—Until quite re- 
cently all black bears in North America were referred to a
