killed hundreds of thousands of sheep, cut down their peach orchards which were scattered about the springs and little streams, destroyed their irrigating works, and devastated their little patches of corn, squashes, and melons; and entirely neglected the Navajos themselves, who were concealed among the rocks of the canyons. Seeing the destruction wrought upon their means of livelihood, the Navajos at once yielded. More than 8,000 of them surrendered at one time, coming in in straggling bands. They were then removed far to the east, near to the Texas line, and established on a reservation at the Bosque Redondo. Here they engaged in civilized farming. A great system

of irrigation was developed; but the appropriations necessary for the maintenance of so large a body of people in the course of their passage from savagery to civilization seemed too great to those responsible for making grants from the national treasury, and just before 1870 the Navajos were permitted to break up their homes at the Bosque Redondo and return to the canyons and cliffs of their ancient land. Millions were spent in conquering them where thousands were used to civilize them, so that they were conquered but not civilized. Still, they are making good progress, and have once more acquired large flocks and herds. It is estimated that they now have more than a million sheep. Their experience in irrigation at the Bosque Redondo has

not been wholly wasted, for they now cultivate the soil by methods of irrigation greatly improved over those used in the earlier time. Originally they dwelt in hogans, or houses made of poles arranged with much skill in conical form, the poles being covered with reeds and the reeds with earth; now they are copying the dwelling places of civilized men. They have also acquired great skill in the manufacture of silver ornaments, with which they decorate themselves and the trappings of their steeds.
Perhaps the most interesting ruins of America are found in this region. The ancient pueblos found here are of superior structure, but

they were all built by a people whom the Navajos displaced when they migrated from the far North. Wherever there is water, near by an ancient ruin may be found; and these ruins are gathered about centers, the centers being larger pueblos and the scattered ruins representing single houses. The ancient people lived in villages, or pueblos, but during the growing season they scattered about by the springs and streams to cultivate the soil by irrigation, and wherever there was a little farm or garden patch, there was built a summer house of stone. When times of war came, especially when they were invaded by the Navajos, these ancient people left their homes in the pueblos and by the streams and constructed temporary homes in the cliffs and canyon
walls. Such cliff ruins are abundant throughout the region, intimately the ancient pueblo peoples succumbed to the prowess of the Navajos and were driven out. A part joined related tribes in the valley of the Bio Grande; others joined the Zuñi and the people of Tusayan; and stall others pushed on beyond the Little Colorado to the San Francisco Plateau and far down into the valley of the Gila.
AN ANCIENT COILED VASE FROM TUSAYAN.
Farther to the east, on the border of the region which we have described, beyond the drainage of the Little Colorado and San Juan and within the drainage of the Rio Grande, there lies an interesting plateau region, which forms a part of the Plateau Province and which is worthy of description. This is the great Tewan Plateau, which carries several groups of mountains. The western edge of this plateau is known as the
Nacimiento Mountain, a long north-and-south range of granite, which presents a bold facade to the valley of the Puerco on the west. Ascending to the summit of this granite range, there is presented to the eastward a plateau of vast proportions, which stretches far toward Santa Fe and is terminated by the canyon of the Rio Grande del Norte. The eastern flank of this range as it slowly rose was a gentle slope, but as it came up fissures were formed and volcanoes burst forth and poured out their floods of lava, and now many extinct volcanoes can be seen. The plateau was built by these volcanoes—sheets of lava piled on sheets of lava hundreds and even thousands of feet in thickness. But with the floods of lava came great explosions, like that of Krakatoa, by which the heavens were filled with volcanic dust. These explosions came at different times and at different places, but they were of enormous magnitude, and when the dust fell again from the clouds it piled up in beds scores and hundreds of feet in thickness. So the Tewan Plateau has a foundation of red sandstone; upon this are piled sheets of lava and sheets of dust in many alternating layers. It is estimated that there still remain more than two hundred cubic miles of this dust, now compacted into somewhat coherent rocks and interpolated between sheets of lava. Everywhere this dust-formed rock is exceedingly light. Much of it has a specific gravity so low that it will float on water. Above the sheets of lava and above the beds of volcanic dust great volcanic cones rise, and the whole upper region is covered with forests interspersed with beautiful prairies. The plateau itself is intersected with many deep, narrow canyons, having walls of lava, volcanic dust, or tufa, and red sandstone. It is a beautiful region. The low mesas on every side are almost treeless and are everywhere deserts, but the great Tewan Plateau is booned with abundant rains, and it is thus a region of forests and meadows, divided into blocks by deep, precipitous canyons and crowned with cones that rise to an altitude of from 10,000 to 12,000 feet.
For many centuries the Tewan Plateau, with its canyons below and its meadows and forests above, has been the home of tribes of Tewan Indians, who built pueblos, sometimes of the red sandstones in the canyons, but oftener of blocks of tufa, or volcanic dust. This light material can be worked with great ease, and with crude tools of the
