The face of the country is made up of fertile valleys, precipitous cañons, rugged mountains, and desert table-lands, the latter predominating and constituting a very large portion of the area. Arizona and New Mexico since first they became known to the outside world, have always had, as they still have, more or less of the mysterious connected with them. Here have been located for over three hundred years the wonderful peoples, marvelous cities, extensive ruins, mines of untold wealth, unparalleled natural phenomena, savages of the most bloodthirsty and merciless character, and other marvels, that from the narratives of adventurers and missionaries have found their way into romance and history. This was in a certain sense the last American stronghold of the mysterious as connected with the aborigines, where the native races yet dispute the progress of a foreign civilization.

And the wondrous tales of this border land between civilization and savagism, always exaggerated, had nevertheless much foundation in fact. The Pueblo tribes of New Mexico and the Moquis of Arizona are a wonderful people when we consider the wall of savagism which envelopes them; their towns of many-storied structures are better foundations than usually exist for travelers' tales of magnificent cities; ruins are abundant, showing that the pueblo nations were in the past more numerous, powerful, and cultured, than Europeans have found them; rich mines are now worked, and yet richer ones are awaiting development; few greater natural curiosities have been seen in America than the cañon of the Colorado, with perpendicular sides in some places a mile in height; and the Apaches are yet on the war-path, making a trip through the country much more dangerous now than at the time when the Spaniards first visited it.

Although a large part of these states is still in the possession of the natives, and no official or scientific commission has made explorations which were especially directed to its antiquarian treasures, yet the labors of the priest, hunter, immigrant, Indian fighter, railroad surveyor, and prospector, have left few valleys, hills, or cañons, mountain passes or desert plains unvisited. While it is not probable that all even of the more important ruins have been seen, or described, we may feel very sure, here as in Yucatan, from the uniformity of such monuments as have been brought to light, that no very important developments remain to be made respecting the character, or type, of the New Mexican remains.

EXPLORATION OF NEW MEXICO.

This country was first visited by the Spaniards in the middle of the sixteenth century. The part known to them as New Mexico, and to which their efforts as conquistadores and missionaries were particularly directed, was the valley of the Rio Grande and its tributary streams, but the whole district was frequently crossed and recrossed by the padres down to the latter part of the seventeenth century. Reports of large cities and powerful nations far in the north reached Mexico through the natives as early as 1530; Cabeza de Vaca, ship-wrecked on the coast of the Mexican gulf, wandered through the regions south of and near New Mexico, in 1535-6; roused by the shipwrecked soldier's tale, Fr Marco de Niza penetrated at least into Arizona from Sinaloa in 1539, and was followed by Vasquez de Coronado, who reached the Pueblo towns on the Rio Grande in 1540; Antonio de Espejo followed the course of the great river northward to the Pueblos in 1583, and in 1598 New Mexico was brought altogether under Spanish rule by Juan de Oñate. In 1680 the natives threw off the yoke by revolt, but were again subdued fifteen years later, and the Spaniards retained the power, though not always without difficulty until 1848, when the territory came into the possession of the United States. The archives of the missions are said to have been for the most part destroyed in the revolt of 1680, and consequently their history previous to that date is only known in outline; since 1680 the annals are tolerably clear and complete. The diaries of the Spanish pioneers have been, most of them, preserved in one form or another, and show that the authors visited many of the ruins that have attracted the attention of later explorers, and also that they found many of the towns inhabited that now exist only as ruins. Their accurate accounts of towns still standing and inhabited attest, moreover, their general veracity as explorers.

It is, however, to the explorations undertaken under the authority of the United States government, for the purpose of surveying a practicable route for an interoceanic railroad, and also to establish a boundary line between American and Mexican territory, that we owe nearly all our accurate descriptions of the ancient monuments of this group. These exploring parties, as well as the military expeditions during the war with Mexico, were accompanied by scientific men and artists, whose observations were made public in their official reports, together with illustrative plates. They generally followed the course of the larger rivers, but the ruins discovered by them show a remarkable similarity one to another, and consequently the reports of trappers and guides respecting remains of similar type on the smaller streams, may be generally accepted as worthy of more implicit confidence than can generally be accorded to such reports.

In this division of Pacific States antiquities, which may be spoken of as the New Mexican group, we shall find, 1st, the remains of ancient stone and adobe buildings in all stages of disintegration, from standing walls with roofs and floors to shapeless heaps of débris or simple lines of foundation-stones; 2d, anomalous structures of stone or earth, the purpose of which, either by reason of their advanced state of ruin or of the slight attention given them by travelers, is not apparent; 3d, traces of aboriginal agriculture in the shape of acequias and zanjas, or irrigating canals and ditches; 4th, pottery, always in fragments; 5th, implements and ornaments of stone and shell, not numerous; and 6th, painted or engraved figures on cliffs, boulders, and the sides of natural caverns.

MOUTH OF THE COLORADO.

About the mouth of the Colorado there are no authentic remains of aboriginal work dating back beyond the coming of the Spaniards, although Mr Bartlett found just below the mouth of the Gila traces of cultivation, which seemed to him, judging from the growth of trees that covered them, not to be the work of the present tribes in the vicinity. I find also an absurd newspaper report—and no part of the Pacific States has been more prolific of such reports than that now under consideration—of a wonderful ruined city of hewn stone somewhere about the head of the Gulf of California. This city included numerous dwellings, circular walls of granite, sculptured hieroglyphics, and seven great pyramids, not unlike the famous Central American cities of Palenque and Copan. Some rude figures scratched or painted on the surface of a boulder, seen by a traveler, have been proved by experience to be ample foundation for such a rumor.[XI-1]
