In the vale of Mexico north-east of Lake Tezcuco, are two pyramidal shaped masses, called the temples of San Juan de Teotihuacan, which the Mexicans had built for the worship of the sun and moon. The temple of the sun is 180 feet in height, with a base of 682 feet; the temple of the moon is not so high or so large, their sides nearly correspond to the cardinal points, and around them are lines of smaller pyramids of about thirty feet in height, which branch off in streets from the faces of the pyramids, and were supposed to be dedicated to the stars; of these there are many hundreds. Time has eradicated the exact forms of them all, but though covered with plants, they are still very apparent. To the south of the Nevado de Toluca is another curious monument called Xochicalco, also a pyramid, with its sides to the cardinal points; it is above 500 feet in height, and divided into five stages covered with stone, the whole being surrounded by ditches; on the top are the ruins of a square building, and the stones of the several platforms are covered with figures; it is supposed to have been an Aztec fortress. The great causeways which led to the ancient Mexico, are now converted into paved roads, but still exhibit all the traces of their wonderful construction. An extended description of the capital of the intendancy having been given, we shall now briefly describe the most noted towns of the province. Of these, _Queretaro_, _Tacubaya_, _Cuernavaca_, _Tascho_, _Acapulco_, _Toluca_, _Zacatula_, and _Pachuca_, are of the greatest note; there are also four mines of much consequence, of which, those of El Doctor and Zimapan, are the most productive. _Queretaro_, in 20° 36ʹ 39ʺ north latitude, 100° 9ʹ 15ʺ west longitude, near the east boundary of Guanaxuato, is celebrated for its manufactures of cloth, its superb aqueduct, and the elegance of the buildings; it is situated at the height of 6374 feet above the level of the sea, and contains 35,000 people, of whom 11,600 are Indians; south of this city is a handsome town, called _San Juan del Rio_, surrounded with beautiful vineyards and gardens. _Tacubaya_, celebrated for its olive grounds and the archbishopʼs palace. _Cuernavaca_ is in a delightful climate, on the southern edge of the Cordillera. _Tasco or Tascho_, has a fine church founded by _Laborde_, a Frenchman, which cost him more than 83,000_l._; he had gained enormous riches by the mines, but was afterwards reduced to poverty.
