in the same localities in bunches of ten to thirty, showing more of 

 an inclination to be sociable than the old males. They seldom drop 

 but one lamb. The rutting season is in November, and the lambs 

 are dropped between April ist and May ist, though in the first 

 week of August, 1897, 1 killed a lamb that I am sure could not have 

 been more than six weeks old. In the second week in August I 

 killed one that was fully four months old. The young rams, up 

 to three years of age, are very unsettled in mind, and range back 

 and forth between the pastures of the females to those of the old 

 males, doing a great deal of travelling, and consequently never 

 acquire as much flesh as the old rams. Like the caribou, they 

 rarely go into the timber, but feed during the winter on the high 

 plateaus, where the wind-swept ridges are usually -free from deep 

 snow. During stormy weather they seek shelter among the rocks, 

 in nooks that are protected from the piercing wind. 



White Mountain Sheep. — I first came into the range of the 

 Oz'is dalli to the north of Beaver River, heretofore described, and 

 I have every assurance that this is their extreme southern range 

 in the Rockies. I also learned beyond doubt that the Ovis stonei 

 and Oz'is dalli do not intermingle in any way, and that the entire 

 coat of the Ovis dalli is white the year round. Specimens killed 

 by me in the Rockies, or, more properly, the Nahannas, a spur 

 of the Rockies, in the latter part of May, showed both the old and 

 new coats, and both were white. 



Further studies of these animals will be made in their northerly 

 ranges. 



Mountain Goat. — White goats are much more plentiful in 

 the Coast Range than in the interior, though they are found in 

 most of the rugged mountains of the entire country travelled by 

 me, with one notable exception. Extending northward from the 

 Liard for a distance of 100 miles, the Indians invariably agreed 

 that no white goats are found in the Rocky Mountain range. The 

 Indians hunt them but little, yet they do not seem to be found 

 anywhere in very large numbers. 



Bears. — The Sitka bear is plentiful on the lower Iskoot, the 

 principal tributary of the Stickine. 



The common brown bear is plentiful throughout the first 100 

 miles of the Stickine as you proceed from the coast, but farther 

 inland, along my route, becomes rare.
