CUAUTLA DE AMILPAS, or CIUDAD MORELOS, is a town in the valley of that name, and made the staunch and memorable resistance to the Spaniards, under the heroic Morelos, during the revolutionary war. It lies 24 leagues S. S. East from the Valley of Mexico,--13 east from Cuernavaca, and is 4,019 feet above the level of the sea. Its climate and productions resemble those of Cuernavaca, but it has never recovered from the effects of the deadly siege. * * * * * Passing in a south-westerly direction from the Valleys of Cuautla, Cuernavaca, Mexico and Toluca, we enter the rich metallic region of Tasco which lies upon the declivities of the Sierra Madre, sloping towards the Pacific. In this district we find the town of TEMASCALTEPEC, which grew up in the midst of a mining country, formerly rich in the production of silver, but now almost abandoned for such purposes. The North Americans were induced to adventure largely in the mines of this district immediately after the revolution, but their capitals were entirely lost in works which were found to have been abandoned by the Spaniards as valueless, long before they were sold by speculators to companies from the United States. The climate of Temascaltepec is mild and agreeable; and, when the mines were productive, it must have been an agreeable residence. The inhabitants, who have abandoned their former mineral speculations, now devote themselves to the manufacture of cotton shawls and _rebozos_. EL VALLE; REAL DEL CRISTO; SULTEPEC; La Plata; TEXUPILLO; ZACUALPAN; HUESULTEPEC; ALMOLOYAN; MALINALTENANGO and TECAMOTEPEC are villages in the vicinity of Temascaltepec. TASCO is a mining town and capital of the canton or district of that name, 5,853 feet above the sea. The village itself is not important, but is nevertheless worthy of note as the oldest mining region in the confederacy. Soon after the conquest it was wrought for _tin_, which had been found in the neighborhood by the Indians; and in the year 1752, Laborde, fully developed its mineral wealth in silver. * * * * * Extending our observations further to the south-west, we reach the district of Acapulco, which is divided between the slopes of the _Sierra_ and the shores of the Pacific. The declivities of the Cordillera are cut by deep vallies, which open their long and regular vistas towards the ocean. The principal places in this part of the State of Mexico, are CHILAPA, with 4,000 inhabitants; MEZCALA; CHILPANTZINGO; MAZATLAN; APANDARO, with 3,500 inhabitants; ZIRANDARO, and ACAPULCO.
