On the mountain which surrounds the north part of this celebrated city, are the remains of the fortress of the Incas, by which it appears that they intended to encompass the mountain with a wall, constructed in such a manner, that the ascent would have been impracticable, though it could be easily defended within. It was strongly built of freestone, and is remarkable for the immense size of the stones, as well as for the art with which they are joined. The internal works of the fortress itself are in ruins, but great part of the wall is standing. A subterraneous passage of singular construction led from this fort to the palace of the Incas, and with these ruins, are the remains of a paved causeway which led to Lima. One of the stones designed for the wall lies on the ground near it, and is so large that it has obtained the name of Cansada, alluding to the apparent impracticability of bringing such a mass from the quarries, by a people unacquainted with machinery, or even by those who are. Most of the houses of Cuzco are covered with red tiles, and built of stone; their interior is spacious, and those of the rich highly decorated; the mouldings of the doors being gilt, and the ornaments and furniture of the most costly kind. The cathedral is a noble building of stone, and is erected on the spot where the Spaniards rescued the place from the Inca Manco Capac the Second; it is served by three priests, one for the Indians, and two for the whites; Cuzco also contains six parish churches, and nine convents, one of which, the Dominican, is built on the spot where stood the Temple of the Sun, the stones of that building serving to erect its church, the altar being paced on the same ground where the golden image of the luminary was formerly fixed. These convents contain hospitals for the sick Indians and whites. There are also four nunneries, and the government of the city consists of a corregidor and alcaldes, who are chosen from the first people in the place. There are four hospitals, two universities, and a college, the latter being for the children of Indian caciques; and the courts are those of the royal audience, revenue, inquisition, cruzada, &c. The bishop of Cuzco is suffragan of the archbishop of Lima, and enjoys a revenue of 24,000 dollars annually. This city contains 32,000 inhabitants, of whom three-fourths are Indians, who are very industrious in the manufacture of baize, cotton and leather, and have a great taste for painting. It formerly contained many Spanish families, but at present the Indians and castes prevail. QUISPICANCHI is a district of Cuzco, beginning close to the city, and extending thirty leagues from east to west, and thirty-five from north to south, producing maize, wheat and fruits. Part of this district borders on the forests inhabited by independent Indians, and which contain great quantities of coca or betel.
