[Footnote 71: "There is no embarrassment growing out of problems respecting the woman's future support, the division of property, or the adjustment of claims for the possession of the children. The independent self-support of every adult healthy Indian, male or female, and the gentile relationship, which is more wide-reaching and authoritative than that of marriage, have already disposed of these questions, which are usually so perplexing for the white man. So far as personal maintenance is concerned, a woman is, as a rule, just as well off without a husband as with one. What is hers, in the shape of property, remains her own whether she is married or not. In fact, marriage among these Indians seems to be but the natural mating of the sexes, to cease at the option of either of the interested parties."

The manner in which the Indians built their houses grew directly out of the requirements of their life. It was an unmistakably characteristic architecture, and while it exhibits manifold unlikenesses in detail, due to differences in intelligence as well as to the presence or absence of sundry materials, there is one underlying principle always manifest. That underlying principle is adaptation to a certain mode of communal living such as all American aborigines that have been carefully studied are known to have practised. Through many gradations, from the sty of the California savage up to the noble sculptured ruins of Uxmal and Chichen-Itza, the principle is always present. Taken in connection with evidence from other sources, it enables us to exhibit a gradation of stages of culture in aboriginal North America, with the savages of the Sacramento and Columbia valleys at the bottom, and the Mayas of Yucatan at the top; and while in going from one end to the other a very long interval was traversed, we feel that the progress of the aborigines in crossing that interval was made along similar lines.[72] [Footnote 72: See Morgan's _Houses and House-Life of the American Aborigines_, Washington, 1881, an epoch-making book of rare and absorbing interest.] [Illustration: Seneca-Iroquois long house.] [Illustration: Ground-plan of long house.] [Sidenote: The long houses of the Iroquois.]
