Though at first the main object for which the buffalo was hunted was the flesh, next in importance and afterwards foremost, was the hide made into the buffalo robe of commerce. Since these robes played such an important part in the early traffic and were partly responsible for the annihilation of the bison, it is worth while to consider how they were procured and treated. The skins to be dressed were taken in the early Spring while the fur was long, thick and luxuriant. Those obtained in the Autumn called "Summer skins" were used only in the making of lodges, clothing, and for other domestic purposes. To the squaws was assigned the preparation of the hides as well as the cutting and curing of the meat. Immediately after the hunt while in the "green" state the skins were stretched and dried. After this, they were taken to the village and subjected to a process of curing which was carried on during the leisure of the women. The hide was nearly always cut down the center of the back so that it could be more easily manipulated. The two parts were then spread upon the ground and scraped with a tool like an adze until every particle of flesh was removed. In this way all unnecessary thickness was obviated and the hide was made light and pliable. When the skin had been reduced to the proper thinness a dressing made of the liver and brains of the animal were spread over it. This mixture was allowed to dry and the same process was repeated save that in the second instance while the hide was wet it was stretched in a frame, carefully scraped with pumice stone, sharp-edged rocks or a kind of hoe, until it was dry. To make it as flexible as possible, it was then drawn back and forth over twisted sinew. The parts were sewed together with sinew and the buffalo robe was ready for the trader's hands.
As early as 1819 these robes were in great demand and one trader reported that in a single year he shipped fifteen thousand to St. Louis.
In the everyday life of the Indians the products of the buffalo yielded nearly every comfort and necessity. The hides were used not only for robes and portable lodges which furnished shelter on the march, but they were made into battle shields; upon their tanned surface the primitive artist traced his painted record of the chase, the fray, or the mystic medicine. They were laid upon the earth for the young braves to play their endless games of chance upon, and the wounded were taken from the field on stretchers of buffalo hides swung between a pair of ponies. From them two kinds of boats were made. One, described by James in his account of the journey of his party in 1819-20 is as follows:
"Our heavy baggage was ferried across in a portable canoe, consisting of a single bison hide, which we carried constantly with us. Its construction was extremely simple; the margin of the hide being pierced with several small holes, admits a cord, by which it is drawn into the form of a shallow basin. This is placed upon the water, and is kept sufficiently distended by the baggage which it receives; it is then towed or pushed across. A canoe of this kind will carry from four to five hundred pounds."
The second variety, known as a "bull-boat," was made of willows woven into a round basket and lined with buffalo hide.
The grease of these beasts was used to anoint the Indians' bodies and to season the maize or corn.
From the horns were made spoons, sometimes holding half a pint, and often ornamented upon the handles with curious carving.
The shoulder blade fastened to a stick served for a hoe or a plow.
From the hide of unborn buffalo calves bags were made to contain the war-paint of braves.
It would be at once possible and profitable to continue enumerating the practical uses of the buffalo, but far more interesting than these facts were the ceremonies, superstitions and traditions in which they were bound up.
