6. _Hunting on Snow-shoes._--"In the dead of the winters," says Mr. Catlin,[61] "which are very long and severely cold in this country, where horses can not be brought into the chase with any avail, the Indian runs upon the surface of the snow by aid of his snow-shoes, which buoy him up, while the great weight of the buffaloes sinks them down to the middle of their sides, and, completely stopping their progress, insures them certain and easy victims to the bow or lance of their pursuers. The snow in these regions often lies during the winter to the depth of 3 and 4 feet, being blown away from the tops and sides of the hills in many places, which are left bare for the buffaloes to graze upon, whilst it is drifted in the hollows and ravines to a very great depth, and rendered almost entirely impassable to these huge animals, which, when closely pursued by their enemies, endeavor to plunge through it, but are soon wedged in and almost unable to move, where they fall an easy prey to the Indian, who runs up lightly upon his snow-shoes and drives his lance to their hearts. The skins are then stripped off, to be sold to the fur traders, and the carcasses left to be devoured by the wolves. [Owing to the fact that the winter's supply of meat was procured and dried in the summer and fall months, the flesh of all buffalo killed in winter was allowed to become a total loss.] This is the season in which the greatest number of these animals are destroyed for their robes; they are most easily killed at this time, and their hair or fur, being longer and more abundant, gives greater value to the robe."
