cultivated by irrigation; cotton being superadded to the maize, beans, squashes, and tobacco, cultivated by the northern tribes. Their houses, with those previously described, represent together an original indigenous architecture, which, with its diversities, sprang out of their necessities. Its fundamental communal type, I repeat, is found not less clearly in the houses about to be described, and in the so-called palace at Palenque, than in the long-house of the Iroquois. An examination of the plan of the structures in Mexico, New Mexico, and Central America will tend to establish the truth of this proposition.
New Mexico is a poor country for civilized man, but quite well adapted to Sedentary Indians, who cultivate about one acre out of every hundred thousand This region, and the San Juan, immediately north of it, possessed a number of narrow fertile valleys, containing together, possibly, 50,000 inhabitants, and it is occupied now by their descendants (excepting the San Juan) in manner and form as it was then. Each pueblo consisted either of a single great house, or of three or four such houses grouped together; and what is more significant, the New Mexican pueblo is a fair type of those now found in ruins in Yucatan, Chiapas, Guatemala, and Honduras, in general plan and in situation. All the people lived together in these great houses on terms of equality, for their institutions were essentially democratical. Common tenements for common Indians around these structures were not found there by Coronado in 1541, neither have any been found there since. There is not the slightest ground for supposing that any such tenements ever existed around those in Yucatan and Central America. Ever} structure was in the nature of a fortress, showing the insecurity in which they lived.
Since the year 1846, the date of the conquest of New Mexico, a number of military reconnaissances, under the direction of the War Department, have been made in various parts of the Territory. The army officers in charge devoted their chief attention to the physical geography and resources of the regions traversed; but, incidentally, they investigated the pueblos in ruins, and the present condition of the Pueblo Indians. The admirable manner in which they have executed the work is shown by the series of reports issued from time to time by the government. More
