Within this region, in the extreme north of Arizona, lie the ruins of three neighboring pueblos. Richard Wetherill, who was one of the discoverers of the famous cliff-cities of the Mesa Verde, was one of the party which found the Kit Siel (Broken Pottery) ruin in 1894 within a long crescent-shaped cave in the side of a glowing red sandstone cliff; in 1908, upon information given by a Navajo Indian, John Wetherill, Professor Byron Cumming, and Neil Judd located Betatakin (Hillside House) ruin within a crescent-shaped cavity in the side of a small red canyon. Twenty miles west of Betatakin is a small ruin known as Inscription House upon whose walls is a carved inscription supposed to have been made by Spanish explorers who visited them in 1661. While these ruins show no features materially differing from those of hundreds of other more accessible pueblo ruins, they possess quite extraordinary beauty because of their romantic location in cliffs of striking color in a region of mysterious charm. II But the Indian civilization of our southwest began very many centuries before the arrival of the Spaniard, who found, besides the innumerable pueblos which were crowded with busy occupants, hundreds of pueblos which had been deserted by their builders, some of them for centuries, and which lay even then in ruins. The desertion of so many pueblos with abundant pottery and other evidences of active living is one of the mysteries of this prehistoric civilization. No doubt, with the failure of water-supplies and other changing physical conditions, occasionally communities sought better living in other localities, but it is certain that many of these desertions resulted from the raids of the wandering predatory tribes of the plains, the Querechos of Bandelier's records, but usually mentioned by him and others by the modern name of Apaches. These fierce bands continually sought to possess themselves of the stores of food and clothing to be found in the prosperous pueblos. The utmost cruelties of the Spanish invaders who, after all, were ruthless only in pursuit of gold, and, when this was lacking, tolerant and even kindly in their treatment of the natives, were nothing compared to the atrocities of these Apache Indians, who gloried in conquest. Of the ruins of pueblos which were not identified with Spanish occupation, six have been conserved as national monuments. THE BANDELIER NATIONAL MONUMENT
