Their costume is very simple, that of the female consisting of a leathern petticoat, reaching the calf of the leg, destitute of a seam, and often exposing a well-formed thigh, as the casualties of wind or position influence the artless foldings of the skirt. The leg and foot are often naked, but usually invested by gaiters and mockasins. A kind of sleeveless short gown, composed of a single piece of the same material, loosely clothes the body, hanging upon the shoulders, readily thrown off, without any sense of indelicacy, when suckling their children, or under the influence of a heated atmosphere, displaying loose and pendant mammæ. A few are covered by the more costly attire of coarse red or blue cloth, ornamented with a profusion of blue and white beads: the short gown of this dress has the addition of wide sleeves descending below the elbow; its body is of a square form, with a transverse slit in the upper edge for the head to pass through; around this aperture, and on the upper side of the sleeves, is a continuous stripe, the breadth of the hand, of blue and white beads, tastefully arranged in contrast with each other, and adding considerable weight as well as ornament to this part of the dress. Around the petticoat, and in a line with the knees, is an even row of oblong conic bells, made of sheet copper, each about an inch and a half in length, suspended vertically by short leathern thongs as near to each other as possible, so that when the person is in motion, they strike upon each other, and produce a tinkling sound. The young unmarried females are more neatly dressed, and seem to participate but little in the laborious occupations, which fall chiefly to the lot of their wedded companions. The dress of the men is composed of a breech cloth, skin leggings, mockasins, and a bison robe. In {48} warm weather the three latter articles of dress are sometimes thrown aside as superfluous, exposing all the limbs and body to view, and to the direct influence of the most ardent rays of the sun. Such are the habiliments that necessity compels the multitude to adopt; but the opulence of a few has gained for themselves the comfortable as well as ornamental and highly esteemed Spanish blanket from the Mexican traders, and of which we had previously seen two or three in the possession of Pawnee warriors worn as trophies. Another species of garment, in their estimation equally sumptuous with the blanket, is the cloth robe, which is of ample dimensions, simple in form, one half red and the other blue, thrown loosely about the person, and at a little distance, excepting the singular arrangement of colours, resembling a Spanish cloak. Some have, suspended from the slits of their ears, the highly prized nacre, or pearlaceous fragments of a marine shell, brought probably from the N. W. coast.
