If now we compare these localities in 1540 with the present sites of the pueblos of New Mexico, it is self-evident that the Zuñi, Acoma, Tiguas, Queres, Jemez, Tehua, and Taos still occupy (Acoma excepted), if not the identical houses, at least the same tribal grounds. The Piros have removed to the frontier of Mexico, the Pecos are extinct as a tribe; of the Tanos and Picuries, a few remain on their ancient soil. Their fate is not a matter of conjecture, but of historical record. While this discussion has proved, we believe, the truthfulness and reliability of the chroniclers of Coronado's expedition, and their great importance for the history of American aborigines, it establishes at the same time the superior advantages of New Mexico as a field for archæological and ethnological study. It is the only region on the whole continent where the highest type of culture attained by its aborigines--the village community in stone or adobe buildings--has been preserved on the respective territories of the tribes. These tribes have shrunk, the purity of their stock has been affected, their customs and beliefs encroached upon by civilization. Still enough is left to make of New Mexico the objective point of serious, practical archæologists; for, besides the living pueblo Indians, besides the numerous ruins of their past, the very history of the changes they have undergone is partly in existence, and begins three hundred and forty years ago, with Coronado's adventurous march.[86] AD. F. BANDELIER. SANTA FÉ, N. M., Sept. 19, 1880. NOTE. THE GRAND QUIVIRA. See p. 26. The following extract is from the "General Description" in the field-notes of the survey in 1872 of the base line of the public surveys in New Mexico by United States Deputy Surveyor Willison, taken from the original notes on file at the United States Surveyor General's office at Santa Fé:-- "The Gran Quivira, about which so much has been written and so many attempts made to reconcile with the city of that name spoken of by the early Spanish explorers, and which was said by them to be the seat of immense wealth, is passed through by the line in Sec. 34, range 8 East. The most prominent building is the church, which, as well as all the other buildings, is of limestone laid in mortar. The ground plan presents the form of a cross. The dimensions of the buildings are as follows:-- "Width of short arm of cross, 33 feet; width of long arm of cross, 42 feet. Their axes are respectively 48 feet long and 140.5 feet long, and their intersection 35 feet from the head of the cross. The walls have a thickness of 6 feet, and a height of about 30 feet. The main entrance has a height of 11 feet, an outside width of 11 feet, and an inside width of 16.5 feet. The church is situated due east and west, having its front to the east.
