This method of securing them can, however, only be embraced when death takes place near the houses, and consequently happens to few. The Mandan and Gros Ventres, being stationed at the fort with those nations, have their dead boxed by the whites and placed on a scaffold made of posts planted near their villages. The Arikara prefer interring them in the ground, and all the rest of the tribes place their dead, secured in the manner described before, in the forks of trees, which in a year or two, as soon as the cords rot off and the envelopes fall to pieces, are blown down, and the bones are found scattered beneath. Carnivorous birds, such as eagles, ravens, and magpies, often pick at the envelope until they get at the body, but if it is well strapped in rawhide it is generally secure from either birds or beasts as long as it remains in the tree. It is the custom of the Assiniboin to put up a funeral flag over the graves of their dead, particularly children, which at this time is composed of some such fabric as red flannel or calico tied to a pole, but which was formerly made of feathers and light skins. This is a very ancient custom, arising, we are told, from the necessity of having some such object thus raised which, fluttering in the wind, frightens away the beasts and birds of prey. The custom of collecting and reinterring the bones is very general at the present day among all these tribes; indeed, it is seldom neglected if when they visit the scaffold they find the body to have blown down and the bones exposed. The bones are picked by any one of the party, not related, in the presence of some of the relatives of the deceased, and this time buried in the ground, with demonstrations of grief and some scarifying, though they do not go into mourning dresses further than some white clay about the face, and no property is confiscated by others, as in the case of the first funeral, but those who aid are paid with some smaller articles. On these occasions a feast is made for the dead which, being eaten, and the spirit propitiated by prayer and invocation, the whole concludes, those concerned resuming their usual dress and occupations. There is no such thing as charnel houses or receptacles for the dead in all the district of the upper Missouri, neither are there any appearances of such things having been, each individual being buried or scaffolded separately at the most convenient place and as soon as possible after decease. Incineration of bones is not practiced by any of them, neither do their traditions mention this custom to have ever existed among them; they have a horror of the idea.
