dicating that an extensive Pueblo town had formerly stood there, but " the structures were probably of adobes," as there was no débris of stone walls, and only very faint traces of foundations. Near the Colorado Chiquito is an extensive ruin, on the summit of an isolated hill of sandstone, the faces of its walls being here and there visible above heaps of débris. It appears to be very old. As near as could be ascertained, the great rectangular Pueblo building was three hundred and sixty feet in extent on one side, and one hundred and twenty on the other. In some places the walls are ten feet thick," with small rooms inserted in them." Stone axes, painted pottery, and other articles are found in the débris: "The indented pottery, said to be so very ancient, is found here in many patterns." On a ridge overlooking the valley of Pueblo Creek are traces of an old settlement of large extent, supposed to have been that heard of in 1539 by the friar Marco de Niça as "the kingdom of Totonteac." Adobe seems to have been used here for building. Traces of other ruins were seen in various places, and springs along the route showing ancient stone-work are mentioned.

Ruins are abundant in the Rio Verde Valley down to the confluence of that river with the Rio Salinas. It is manifest that this whole region was anciently far more populous than it is now. Lieutenant Whipple says, "Large fields in the valley of the Rio Gila, and many spots among the Pinal Lena Mountains, are marked with the foundations of adobe houses." Figure 22 represents a Pueblo ruin in the Valley of the Gila. "In Cañon

Chelly, near San Francisco Mountain, and upon Rio Verde, there are ruins of more permanent structures of stone, which in their day must have excelled the famed Pueblos of New Mexico." There was a higher degree of civilization in the ancient times, so far as relates to architecture and skill in the arts and appliances of life, than has been shown by people of the same race dwelling there in our time; but the ancient condition of life seems to have been maintained from age to age without material change.

THE SEVEN CITIES OF CEVOLA." In the New Mexican valley of the Chaco, one degree or more north of Zuni, are ruins of what some suppose to have been the famous "Seven Cities of Cevola." In 1540, Spanish cupidity having been strongly incited by tales of the greatness and vast wealth of Cevola, Coronado, then governor of New Galicia, set out with an army to conquer and rob its cities. The report in which he tells the story of this conquest and of his disappointment is still in existence. The Cevolans defended themselves with arrows and spears, and hurled stones upon his army from the tops of their buildings. But resistance was of no avail; Cevola was conquered by Coronado, and immediately deserted by all its inhabitants who escaped death. The conquering buccaneer, however, did not find the treasures of gold and silver he expected. Three hundred and thirty years or more have passed away since this expedition of the Spanish marauders was undertaken, but the "Seven Cities of Cevola" (if they really were

the "cities" whose remains are found in the Chaco Valley), although much dilapidated, are still sufficiently well preserved to show us what they were.

There are seven ruins in the Chaco Valley, all of the same age, from one to three miles apart, the whole line along which they are situated being not more than ten miles in extent. Coronado said of Cevola, "The seven cities are seven small towns, standing all within four leagues together;" and "all together they are called Cevola." The Chaco ruins show that each of these "cities" was, Pueblo fashion, a single edifice of vast size, capable of accommodating from five hundred to three thousand people. They were all built of stone, around three sides of a square, the side opposite the main building being left open. Figure 23 represents one of these buildings restored, according to Lieutenant Simpson. Figure 24 is a ground plan of this structure. The outer faces of the walls were constructed with thin and regular blocks of sandstone; the inner surfaces were made of cobblestone laid in mortar, and the outer walls were three feet thick. They were four or five stories high, and the only entrances to them were "window openings" in the second story. Above the cañon inclosing the valley containing these ruins, at a distance of thirteen miles, are the remains of another "city" of precisely the same kind. Its walls are at present between twenty and thirty feet high, their foundations being deeply sunk into the earth. Lieutenant Simpson, who explored that region in 1849, says it was built of tabular pieces of hard, fine-grained, compact gray sandstone, none of the layers being more
