Two miles from Tezcuco, the village of Huexoila, situated on the site of the ancient city of that name, which was considered as one of the suburbs of Tezcuco, exhibits signs of ancient civilization, in the foundations of large edifices,

in massive Aqueducts, one of which, covered with rosecolored cement, still exists in a perfect state, and in an extensive wall of great height and thickness. A covered way flanked by parallel walls proceeds from the ancient city, to

the bed of a stream now dry, over which there is a remarkable bridge, with a pointed arch 40 feet high, and supported on one side by a pyramidal mass of masonry.

Tlascala was furnished with abundance of baths and fountains, and Zempoala, like the city of Tezcuco, had every house supplied with water by a pipe.

Iztaclapa, which contained about ten thousand houses,

had its Aqueduct that conveyed water from the neighboring mountains, and led it through a great number of well cultivated gardens.

Among the ruins of the city of Zacatecas, are found the remains of an Aqueduct ; and at Palenque is found an Aqueduct of stone, constructed with the greatest solidity.

Among the hieroglyphical ornaments of the pyramid of Xochicalco are heads of crocodiles spouting water, and much proof may be found that the ancient Americans were acquainted with that property of liquids by which they find their level ; and applied it not merely to fountains and jets d'eau, but to convey water through pipes to their dwellings.
