A TYPICAL He;aD of WHITE RAM 
In 1884 E. W. Nelson first described a pure white species of mountain sheep inhabiting 
Alaska and northwestern Canada, naming it Oz'is dalli. in honor of Prof. Wm. H. Dall, the 
well-known scientist and Alaskan explorer. While the horns of this species are not as

of the Big Horns or to those of the southern California species, the extensive spread and

stunted hemlock for firewood, a small 
tent was erected for me to spend the

moose. Most interesting of all this limit- 
less scenery was Cook Inlet, looking like 
a giant river and banked on the western 
side by the mountains of the Alaska 
Range, the great cordillera of the Terri- 
tory, with Mount McKinley as the key- 
stone in the semicircular swing of this 
great upheaval.
