In view of the discoveries further north, we would respectfully suggest that this was, in reality, the lower story of the building, whose flat roof formed the terrace in front of the second story, whose foundation M. Charney so happily discovered. But such suggestions as this are very unsafe to make, and must be supported by further discoveries before they are of any real value.

He found a large number of good-sized rooms, and speaks especially of one hall fifty feet square, in the center of which was six pillars, sloping from the base upwards. They, doubtless, served to support the roof. We regret that we have not been able to see M. Charney’s ground plan of this ruin. Of the pyramids themselves we have quite full information. The larger one, that of the sun, is seven hundred and sixty feet square and two hundred and sixteen feet high. It will be seen that these dimensions throw the great mound at Cahokia into the shade. Though the base may not be quite as great, the height of the pyramid is over twice that of the mound. Three terraces are plainly visible. The surface was covered with cement, large slabs of which remain in their place. The moon pyramid is further north.

It is in all respects like that of the sun, but of smaller dimensions, being one hundred and fifty feet high. In early times these pyramids are said to have supported statues, but, if so, they have long since been thrown down. Their surface and the ground around is thickly strewn with fragments of pottery, obsidian knives, and other small relics. Running south from the House of the Moon, and passing a little to one side of the House of the Sun, are the remains of a wide, paved road. Its width is stated to be one hundred and thirty feet, and its length about two hundred and fifty rods.17

This road suddenly expands in front of the Moon, so as to suggest the idea of a Greek cross. Pieces of cement (with which this road was covered) are still visible in places. It is lined with mounds on either side, and they stand so close together as to resemble continuous embankments in some places. Speculations are abundant as to the object of this graded way. Tradition calls it the “Path of the Dead.” Small mounds are very numerous over the surface. They may have been for burial purposes, but sculptured stones are found in them, and specimens of hard cement. This group of ruins is regarded as of very great antiquity.

We can easily see that the growth of the soil formed by the decay and detrition of the stone slabs of the pyramids, temples, and other buildings would be slow, especially as the rainfall is light. But in some localities it is more than three feet thick. In places three separate floors are observed, one over the other, pointing to as many successive occupations of the same sections by men.

About sixty-five miles to the north of Mexico was located Tollan, or Tulla. According to tradition, this was the capital city of the Toltecs, a mysterious people who long preceded the Aztecs. We are told that “extensive ruins remained at the time of the conquest, but very few relics have survived to the present time.”18 M. Charney, whose labors we have referred to at Teotihuacan, succeeded also in making important discoveries here. He tells us that on the site of this ancient capital there is a hill, “about one mile long by half a mile broad, covered with mounds, plateaus, and ruins of all kinds.”

He gives us the dimensions of two pyramids, as follows. The first is one hundred and ninety-six feet on each front, and forty-six feet high. The second is one hundred and thirty-one feet square, and thirty-one feet high. Both of these pyramids stood on raised foundations, which M. Charney calls esplanades. As no other pyramids are mentioned, we are to suppose these are the two principal ones. Perhaps they are also pyramids of the sun and moon. Our chief interest is concerned with the remains of the habitations he discovered here. He says: “I set the men to work at one of the many mounds upon the ridge, and soon found that I had hit upon a group of habitations.” A general idea of this group of buildings is given in this passage: “The dwellings were united together in groups, and erected on isolated mounds, one in the middle, the others around about, the whole forming a sort of honey-comb, with its cells placed at different elevations.”

We can not help being struck with the general resemblance of the descriptions here given and that of the ruins in the vicinity of the River Gila. The general tendency is seen to gather together in clusters, with, probably, the most important house in the center. As to the materials used in this building, we are told “they used clay and mud for the inside of the walls, cement to coat them, dressed stone and brick for casings, bricks and stone for stairways, bricks for pilasters, and wood for roofing the edifice. The houses bad flat roofs, consisting of timbers coated with cement. Of such timbers we find vast quantities.”19

Of the arrangements of the rooms, he tells us, “The apartments that have been brought to light comprise a number of chambers, big and little, placed at different heights. We shall have no clear idea of the relation of these different chambers to one another, or of the mode of access to them through the labyrinthine passages and the numerous stairways, until the whole edifice has been unearthed.”

This was not the only building he discovered. On digging into a mound supposed to be the support of a temple, he discovered it was the ruined foundation of a still grander house. He says, “It is much larger than the other one, stands on a pyramid, and has two wings inclosing a courtyard. The walls are thicker than those of the first habitation, and more strongly built. The apartments, too, are larger, though arranged in a similar fashion.” Elsewhere he tells us that this building contained at least forty-three apartments, large and small. We presume very few will now question but what the buildings he here describes are ruined communal buildings, much like the structures in Arizona.
