It is admitted now by all archaeologists that the ancient works of New York are attributable to Indians, chiefly to the Iroquois tribes. This necessarily carries with it the inference that works of the same type, for instance those of northern Ohio and eastern Michigan, are due to Indians. It is also admitted that the mounds and burial pits of Canada are due, at least in part, to the Hurons. [Footnote: David Boyle, Ann. Rept. Canadian Institute, 1886-1887, pp. 9-17; Ibid., 1888, p. 57.] Tribal divisions.--As the proofs that the mound-builders pertained to various tribes often at war with each other are now too numerous and strong to be longer denied, we may see in them evidences of a social condition similar to that of the Indians. Similarity in burial customs.--There are perhaps no other remains of a barbarous or unenlightened people which give us so clear a conception of their superstitions and religious beliefs as do those which relate to the disposal of their dead. By the modes adopted for such disposal, and the relics found in the receptacles of the dead, we are enabled not only to understand something of these superstitions and beliefs, but also to judge of their culture status and to gain some knowledge of their arts, customs, and modes of life. The mortuary customs of the mound-builders, as gleaned from an examination of their burial mounds, ancient cemeteries, and other depositories of their dead, present so many striking resemblances to those of the Indians when first encountered by the whites, as to leave little room for doubt regarding their identity. [Footnote: Evidence bearing on this point will be found in the paper on The Burial Mounds of the Northern Sections, by C. Thomas, in the Fifth Annual Report of the Bureau of Ethnology.] Nor is this similarity limited to the customs in the broad and general sense, but it is carried down to the more minute and striking peculiarities. Among the general features in which resemblances are noted are the following: The mound-builders were accustomed to dispose of their dead in many different ways; their modes of sepulture were also quite varied. The same statements will apply with equal force to the Indians. "The commonest mode of burial among North American Indians," we are informed by Dr. H. C. Yarrow, [Footnote: First Annual Report Bureau of Ethnology, Smithsonian Institution, 1879-'80 (1881), p. 93.] "has been that of interment in the ground, and this has taken place in a number of ways." The different ways he mentions are, in pits, graves, or holes in the ground; in stone graves or cists; in mounds; beneath or in cabins, wigwams, houses or lodges, and in caves.
