the Rocky mountains—its recent remains having been found in Oregon as 
far west as the Blue mountains, and further south it occupied the Great 
Slave Lake basin, extending westward even to the Sierra Nevada mount¬ 
ains, while less than fifty years since it existed over the headwaters of the 
Green and Grand rivers, and other sources of the Colorado. East of the 
Rocky mountains its range extended southward far beyond the Rio Grande, 
and eastward through the region drained by the Ohio and its tributaries. 
Its northern limit, east of the Mississippi, was the great lakes, along which 
it extended to near the eastern end of Lake Erie. It appears not to have 
occurred south of the Tennessee river, and only to a limited extent east 
of the Alleghenies, chiefly in the upper districts of North and South 
Carolina. 
“ Its present range embraces two distinct and comparatively small areas. 
The southern is chiefly limited to western Kansas, a part of the Indian 
Territory, and north-western Texas—in all together embracing a region 
about equal in size to the present State of Kansas. The northern district 
extends from the sources of the principal southern tributaries of the Yel¬ 
lowstone northward into the British possessions, embracing an area not 
much greater than the present territory of Montana. Over these regions, 
however, it is rapidly disappearing, and at its present rate of decrease will 
certainly become wholly extinct within the next quarter of a century.” 
THE BISON. 
Over nearly the whole of this country the bison formerly 
ranged in vast herds, and the destructive side of man’s nature 
cannot be better realized than in contemplating the details 
of its extinction. It has been estimated by careful and
