From the bath, we continued our walk along the terrace, upon which still exist traces of an aqueduct, which, at the eastern extremity of Tescusingo, crossed from the contiguous mountain upon an artificial pile of stone, conveying water, we were informed, a distance of seven or eight leagues. We were yet several hundred feet from the top. Ascending farther, we encountered other remains of structures, and came to a levelled surface about fifty feet square. All these are convincing proofs of the numerous edifices which once existed upon this mountain, but we must ever remain ignorant of their nature and purpose. Upon the summit, which commands a fine view of the surrounding country, is a rock of huge size, in which seats have been cut.

In our descent on the northern side, which is very rough and steep, we discovered accidentally a flight of seven steps cut out of a single rock—of these, our guide, an Indian antiquarian of Tescuco, had heretofore been ignorant. Many objects worthy of investigation will no doubt reward those who should diligently extend their researches upon the mountain of Tescusingo. We reached the foot without further incident, and rejoined our carriage at the mill, much fatigued with our ramble under a burning sun. Soon after four we were again under the roof of our kind host.

After dinner, our friend, Don Nicolas Campero, conducted us to the ruins which I have already mentioned to be just without the gate of the town. Their structure and extent are marked by the revolutionary trenches which surround them. The occasional layers of cement are perpendicular as well as horizontal, and between them are laid adobes—unburnt bricks—which compose the work. Judging from appearances, it would not be rash, perhaps, to conjecture that this was the site of the Great Temple, which, we are assured, was always constructed upon eminences like this. Its distance from the palace amply proves the extent of the ancient city of Tescuco to have been very great.

DEC. 27. After breakfast, we rode a league to see the ahuahuetes2—cypress trees—of large dimensions, some of them are not less than fifty feet in circumference. A large edifice, it is believed, stood once in the midst of them. There are traces of buildings. The regularity with which these trees are disposed, proves, beyond a doubt, that they were planted. They are so regular, that in order to enclose three sides of a square it was necessary to lay a few adobes only between them. Two rows of these trees form a long street. This grove of ahuahuetes is seen distinctly from the city of Mexico, their deep green contrasting strongly with the dry and open plain which surrounds them.

We employed the afternoon in revisiting the antiquities of Tescuco. We were also conducted to the garden belonging to the convent of San Francisco, where a remarkable carved stone lies neglected under a tree. It is round and represents a man, whose nose is prodigious, in a kneeling attitude, holding something—what it is we could not discover—in his hands; behind him is another figure, which defied all our efforts to decipher it.

At night, we accompanied the young ladies of the house to a ball given by the principal merchant of the town. The room was filled with men, women, and cigar smoke. This compelled us to make an early retreat, for our eyes were not yet insensible to its effect.

DEC. 28. After an early breakfast, and the completion of some repairs to our coach, we took leave of the excellent family who had entertained us most hospitably. We now directed our steps towards Otumba. Passing several small villages—some of them are very picturesque, with their enclosures of the cactus cylindricus, which grows to the height of fifteen or eighteen feet—the country became barren and uninteresting, until we reached the fine hacienda of San Antonio. Here we deviated from the direct route, but were compensated for the loss of time by the sight of an extensive stone wall, built to contain water for the purpose of irrigating the estate, and for the use of the cattle. This large presa—or pond—was the work of the Jesuits, who formerly owned the finest property in New Spain, and who were sagacious and industrious in improving their possessions. Retracing our steps, we passed the extensive buildings of San Antonio, leaving immediately upon our left its beautiful wheat fields, which the laborers were then engaged in watering. This is the dry season, and wheat will grow only where it can be irrigated frequently.

Beyond the village of San Pedro, we ascended the tepetate3 lomes—lomas—of the eastern side of the plain of Mexico, upon which soil the roads are always worn deep and rough. On arriving at the summit of a low ridge which we were crossing, the Pyramids of Teotihuacán unexpectedly presented themselves to our view. Though ignorant that we were so near to them, yet we could not mistake them, their figure is still so well preserved, whilst centuries have rolled away since their construction.
