_Argali._――The argali is found in the Rocky Mountains, from about the fiftieth degree of north latitude to California. Here troops of twenty or thirty are seen together, feeding on the most precipitous tracts, and bounding with wonderful agility from rock to rock. During the summer months, the color of this animal is a grayish fawn, with a reddish line across the back. The male has very large twisted horns, fixed near the eyes; its ears are straight, broad and pointed, and its tail quite short. This is said to be the species from which all the varieties of our domestic sheep are descended. _Bison._――This animal is found in herds in the prairies in the neighborhood of the Rocky Mountains: it is continually receding before the advance of man, and will soon be entirely banished to the far west. Schoolcraft says that the species is confined to the regions situated between the thirty-first and forty-ninth degrees of north latitude, and west of the Mississippi river. The only part of the country east of this river, where the bison now remains, is that included between the falls of St. Anthony and Sandy Lake, a range of about six hundred miles. ‘Being now in the region of buffalo,’ says Mr. Schoolcraft, ‘we concluded to land, in the course of the day, at some convenient place for hunting them. This we were soon invited to do by seeing one of these animals along the shore of the river, and on ascending the bank, we observed, upon a boundless prairie, two droves of them, feeding upon the grass. All who had guns adapted for the purpose, sallied forth in separate parties upon the prairie, while those who felt less ambition to signalize themselves upon the occasion, or were more illy accoutred for the activities of the chase, remained upon an eminence which overlooked the plain, to observe the movements of this animal while under an attack of musketry, and to enjoy the novel spectacle of a buffalo-hunt. The grass was so tall as to allow an unobserved approach towards the spot where they remained feeding, but the first fire proved unsuccessful, at the same time that it scattered the herd, which were now seen running in all directions across the prairie, and an incessant fire of random shots was kept up for about two hours; during which three buffaloes were killed, and a great number wounded, which made their escape.
