The fore parts of the body are covered with long shaggy hair, descending in a tuft behind the knee, in a distinct beard beneath the lower jaw, rising in a dense mass on the top of his head as high as the tip of the horns, matted and curled on his front so {157} thickly as to deaden the force of the rifle-ball, which rebounds from the forehead, or lodges in the hair, causing the animal only to shake his head as he bounds heavily onward. The head is so large and ponderous, in proportion to the size of the body, that the supporting muscles, which greatly enlarge the neck, form over the shoulders, where they are imbedded on each side of elongated vertebral processes, distinguished by the name of hump ribs, a very considerable elevation called the hump, which is of an oblong form, diminishing in height as it recedes, so as to give considerable obliquity to the line of the back. The eye is small, black, and piercing; the horns, which are black, and remarkably robust at base, curve outward and upward, tapering rapidly to the tip. The profile of the face is somewhat convexly curved; and the superior lip, on each side, papillous within, is dilated and extended downward, so as to give a very oblique appearance to the lateral rictus, or gape of the mouth, considerably resembling in this respect the ancient architectural bas-reliefs representing the heads of the ox. The physiognomy is menacing and ferocious, and the whole aspect of the animal is sufficiently formidable to influence the spectator who is, for the first time, placed near him in his native wilds, with certain feelings which indicate the propriety of immediate attention to personal safety. The bison cow bears the same relation, as to appearance, to the bull, that the domestic cow does to her mate; she is smaller, with much less hair on the anterior part of her body, and though she has a conspicuous beard, yet this appendage is comparatively short; her horns also are much less robust, and not partially concealed by hair. The dun colour prevails on the coat of the bison; but the long hair of the anterior part of the body, with the exception of the head, is more or less tinged with yellowish or rust colour. The uniformity of {158} colour, however, amongst these animals is so steadfast, that any considerable deviation from the ordinary standard is regarded by the natives as effected under the immediate influence of the Divinity. A trader of the Missouri informed us that he had seen a grayish-white bison, and that another, a yearling calf, was distinguished by several white spots on the side, and by a white frontal mark and white fore feet. Mr. J. Dougherty saw in an Indian hut a bison head, very well prepared, which had a white star on the front; the owner valued it highly, calling it his great medicine; he could not be tempted to part with it; "for," said he, "the herds come every season into the vicinity to seek their white-faced companion."
