THE AMERICAN BISONS. 167 
there are several well known salt-licks, where bison are sure to be found at 
all seasons of the year. They do not frequent any of the districts formed of 
primitive rocks, and the limits of their range to the eastward within the 
Hudson Bay Company’s territories may be correctly marked on the map by 
a line commencing in longitude 97° on the Red River which flows into the 
south-end of Lake Winipeg, crossing the Saskatchewan to the westward of 
the Basquian hill, and running thence by the Athapescow to the east end 
of Great Slave Lake. Their migrations to the westward were formerly lim- 
ited by the Rocky Mountain range, and they are still unknown in New Cale- 
donia and on the shores of the Pacific to the north of the Columbia River; 
but of late years they have found out a passage across the mountains near 
the sources of the Saskatchewan, and their numbers to the westward are 
said to be annually increasing.” * The range of the buffalo in British 
America was hence co-extensive with the prairies, meeting the range of the 
musk-ox on the north, and the prairies and plains of the United States on 
the south. It was not, however, exclusively confined to the plains, and 
apparently less so at the northward than toward the south. Besides posi- 
tively forsaking the more exposed portions of the northern plains and seek- 
ing refuge in the woods during the severer periods of cold in winter, they are 
said to frequent, at all seasons, the timber adjoining the prairie districts. In 
a later work Dr. Richardson refers to the range of this animal as follows: 
“The bison, though inhabiting the prairies in vast bands, frequents also the 
wooded country, and once, I believe, almost all parts of it. down to the coasts 
of the Atlantic; but it had not until lately crossed the Rocky Mountain 
range, nor is it now known on the Pacific Slope, except in a very few places. 
Its most northern limit is the Horn Mountain [in latitude 62°].”+ To the 
northward of the Saskatchewan, the prairie country is confined to limited 
areas, and there buffaloes range extensively through the open woods The 
habitat of the bison north of the United States, at the beginning of the 
present century, hence embraced a triangular area, extending through about 
seventeen degrees of longitude (from 96° to 113°) on the northern boun- 
dary of the United States, decreasing in breadth northward to a narrow point
