"H. C. YARROW."
This was forwarded to every Indian agent, physicians at agencies, to a great number of Army officers who had served or were serving at frontier posts, and to individuals known to be interested in ethnologic matters. A large number of interesting and valuable responses were received, many of them showing how customs have changed either under influences of civilization or altered circumstances of environment.
Following this, a comprehensive list of books relating to North American Indians was procured, and each volume subjected to careful scrutiny, extracts being made from those that appeared in the writer's judgment reliable. Out of a large number examined up to the present time, several hundred have been laid under contribution, and the labor of further collation still continues.
It is proper to add that all the material obtained will eventually be embodied in a quarto volume, forming one of the series of contributions to North American Ethnology prepared under the direction of Maj. J. W. Powell, Director of the Bureau of Ethnology, Smithsonian Institution, from whom, since the inception of the work, most constant encouragement and advice has been received, and to whom all American ethnologists owe a debt of gratitude which can never be repaid.
Having thus called attention to the work and the methods pursued in collecting data, the classification of the subject may be given and examples furnished of the burial ceremonies among different tribes, calling especial attention to similar or almost analogous customs among the peoples of the Old World.
For our present purpose the following provisional arrangement of burials may be adopted:
1st. By INHUMATION in pits, graves, holes in the ground, mounds; cists, and caves.
2d. By CREMATION, generally on the surface of the earth, occasionally beneath, the resulting bones or ashes being placed in pits, in the ground, in boxes placed on scaffolds or trees, in urns, sometimes scattered.
3d. By EMBALMENT or a process of mummifying, the remains being afterwards placed in the earth, caves, mounds, or charnel-houses.
4th. By AERIAL SEPULTURE, the bodies being deposited on scaffolds or trees, in boxes or canoes, the two latter receptacles supported on scaffolds or posts, or on the ground. Occasionally baskets have been used to contain the remains of children, these being hung to trees.
