But perhaps the most interesting result of his labors was the proof that these ruins were certainly inhabited after the conquest—for how long a time we can not tell. This is shown by fragments of bones and other articles found in the refuse heaps. The bones were of such animals as the horse, swine, sheep, oxen, etc.—animals introduced into this country by the Spaniards. The fragments of pottery include specimens plainly not of Indian manufacture, such as fragments of porcelain, and that variety of glazed ware known as delf, and lastly, the neck of a glass bottle. It may be said that these fragments might have been left by a band of Spaniards who occupied the ruins in the early days of the conquest, perhaps long after the Indian owners had left. This is of course possible, but it is just as reasonable to suppose the fragments were left by descendants of the original builders.
Northward from Tulla is a small province, marked on the map Querataro. From the accounts at our disposal, which are very brief, we gather that this whole section is a tableland split up by ravines of great depths and precipitous sides; consequently one abounding in easily defended positions. It was found that all the projecting points, naturally strong, were rendered still stronger by the presence of ditches, walls, and embankments. Three groups of ruins are mentioned especially, and their location is marked on the map. At Pueblito there was, at an early day, plainly to be seen, the foundation of a large, rectangular building. The walls were built of stone laid in clay.
At Canoas, in the northern part of the State, there is a steep and strongly fortified bill, but particulars in regard to it are very meager. “There are, in all, forty-five defensive works on the hill, including a wall about forty feet in height, and a rectangular platform with an area of five thousand square feet.”20 Ranas, the most northern one of the three sites mentioned, is regarded as the center of population in early times. “A small lake and a perennial spring are supposed to have been the attractions of this locality in the eyes of the people. On all the hills about are still seen vestiges of their monuments.”
If we look at the map we will notice that we have gone but a little ways north of the valley of Anahuac. Yet, with the exception of the Gulf-coast, there are but few striking aboriginal ruins in Northern Mexico. At the time of the conquest the whole northern section was the home of tribes not generally considered to be as far advanced as those who lived in the section we have already described, and in regions further south. Yet it is certainly hard to draw the line between the culture of the two people. We are told that, these Northern tribes though styled “dogs,” and “barbarians,” by the Southern tribes, were yet “tillers of the soil, and lived under systematic forms of government, although not apparently much given to the arts of agriculture and sculpture.”
This point is of considerable interest to us, theoretically; for it is a question from whence came the various Nahua tribes. We would naturally think, if they came from the North, we ought to find evidence of their former presence in the various Northern States of Mexico. We must remember, however, that a migrating people are not apt to leave monuments until they reach the end of their migration. Neither has the territory been as carefully explored as it should be. What accounts we can obtain of the remains in this section are certainly very meager. But one place in Sonora do ruins occur, and they have never been examined by competent personages.21 In Chihuahua occur ruins, evidently the works of the same people as built the separate houses to the west of the Rio Grande, in New Mexico.
These ruins have received the same name as those on the Rio Gila—that is, “Casas Grandes,” meaning “Great House.” This cut represents a view of these ruins. The river valley is here about two miles wide, and is said to be very fertile. Mr. Bartlett thinks there is no richer valley to be found from Texas to California. This valley was once the seat of a considerable population. Mounds are here found in considerable numbers. Over two thousand are estimated as occurring in a section of country sixty miles long by thirty in width.22 We wish we knew more about the mounds. They are said to contain pottery, stone axes, and other implements. It is possible, then, that these mounds are ruins of separate houses. At any rate, such are the only kind of ruins noticed in the upper part of this same valley by Mr. Bandelier.
The ruins in question are undoubtedly those of a rich and prosperous pueblo. They are so placed as to command a very extensive view. The river valley is cut through a plain, and has precipitous sides about twenty-five feet in height. The ruins in question are found partly in the bottoms and partly on the upper and more sterile plateau. The walls were made of adobe, and in consequence of their long exposure to the elements are very far gone in ruins; so much so that Mr. Bartlett was unable to make out the plan. But enough was seen to show that this was a pueblo much like the structure already described. They properly belong to the Arizona group of ruins.
We are told they face the cardinal points, and consist of fallen and erect walls. The portions still standing are from fifty to sixty feet high, or rather were that height in 1851. It is doubtful whether any thing more than a mound of adobe mud now marks the spot. The walls were highest in the center of the mass. At the distance of a few miles was a hill said to be fortified. But the descriptions of it are conflicting. Some represent it as crowned with a stone-built fortress two or three stories high. Others more reasonable, represent it as the site of a watch-tower, or sentry station, and that at regular intervals on the slope of the hill are lines of stone, with heaps of loose stones at their extremities.23 Probably the same fate overtook the tribes of this valley as did the sedentary tribes of the North. They would not willingly abandon a place so well suited to their needs. The presence of an invading foe, cruel and vindictive, alone accounts for this group of ruins.
