So then is this sachem (the buffalo’s back fat) dressed; and in a very similar manner, and almost the same, is each of the others above named; and all are armed with bow and quiver, lance and shield. These north-western tribes are all armed with the bow and lance, and protected with the shield or arrow fender, which is carried outside of the left arm, exactly as the Roman and Grecian shield was carried, and for the same purpose. There is an appearance purely classic in the plight and equipment of these warriors and “knights of the lance.” They are almost literally always on their horses’ backs, and they wield these weapons with desperate effect upon the open plains; where they kill their game while at full speed, and contend in like manner in battles with their enemy. There is one prevailing custom in these respects, amongst all the tribes who inhabit the great plains or prairies of these western regions. These plains afford them an abundance of wild and fleet horses, which are easily procured; and on their backs at full speed, they can come alongside of any animal, which they easily destroy. The bow with which they are armed is small, and apparently an insignificant weapon, though one of great and almost incredible power in the hands of its owner, whose sinews have been from childhood habituated to its use and service. The length of these bows is generally about three feet, and sometimes not more than two and a half (+plate+ 18 _a_). They have, no doubt, studied to get the requisite power in the smallest compass possible, as it is more easily and handily used on horseback than one of greater length. The greater number of these bows are made of ash, or of “bois d’arc” (as the French call it), and lined on the back with layers of buffalo or deer’s sinews, which are inseparably attached to them, and give them great elasticity. There are very many also (amongst the Blackfeet and the Crows) which are made of bone, and others of the horn of the mountain-sheep. Those made of bone are decidedly the most valuable, and cannot in this country be procured of a good quality short of the price of one or two horses. About these there is a mystery yet to be solved, and I advance my opinion against all theories that I have heard in the country where they are used and made. I have procured several very fine specimens, and when purchasing them have inquired of the Indians, what bone they were made of? and in every instance, the answer was, “That’s medicine,” meaning that it was a mystery to them, or that they did not wish to be questioned about them. The bone of which they are made is certainly not the bone of any animal now grazing on the prairies, or in the mountains between this place and the Pacific Ocean; for some of these bows are three feet in length, of a solid piece of bone, and that as close-grained—as hard—as white, and as highly polished as any ivory; it cannot, therefore be made from the elks’ horn (as some
