As one approaches the center of Arizona, along the line of the Santa Fé Railroad, whether he come from the east or from the west, his attention is sure to be arrested by several tall, spire-like hills which are silhouetted against the sky to the far north. These peaks are the Moki Buttes, and to the north of them lies the province of Tusayan, the land of the Mokis, or the Hopis, as they prefer to be called. That country to-day contains more of interest to the student of the history of mankind than any other similar-sized area on the American continent. But very few of the great throng that roll by on the Santa Fé trains every year in quest of pleasure, of recreation, of new scenes and strange, stop off at Holbrook or Winslow to take the journey to the Hopis, and very few even know of the existence of these curiously quaint pueblos of this community, which to-day lives pretty much as it did before Columbus set out on his long voyage to the unknown West. The term _pueblo_, a Spanish word meaning town, is by long and continued use now almost confined to the clusters of stone and adobe houses which to-day shelter the sedentary Indians of New Mexico and Arizona. Not only are these Indian towns called "pueblos," but we speak of the Indians themselves as the Pueblo Indians, and of the culture of the people--for they all have much in common--as the pueblo culture. This similarity of culture is not due to unity of race or of language, but is the resultant of a peculiar environment. In recent times, the limits of the pueblo-culture area have contracted to meet the demands of the white man; we know also that before the advent of the Spaniard many once populous districts had been abandoned, and as a result there came to be fewer but larger villages. We know also, both from tradition and from archæological evidence, that in former days the pueblo people inhabited many of the villages of southern Colorado and Utah, and that the Hopis and their kin were numerous in many parts of Arizona. The silent houses of the cliffs, the ruins of central Arizona, and the great crumbling masses of adobe of the Salt and Gila River valleys and in northern Chihuahua are all former habitations of the Pueblo Indian. To-day there are no representatives of these people in Utah or Colorado, while the seven Hopi towns of Tusayan alone remain in Arizona. But there are still many pueblos scattered along the Rio Grande, Jemez, and San Juan Rivers in New Mexico. Alike in culture, we may divide the existing pueblos into four linguistic groups--namely, the Hopis of Arizona, the Zuñis of New Mexico, the Tehuas east of the Rio Grande, and the Queres to the west of the Rio Grande. Of the earlier home of the last three stocks we know but little. The ancestors of the Hopis we know came from different directions--some from the cliff dwellings of the north, others from central Arizona. To-day, however, they form a congeries of clans
