"Some of these stones were hewn from the hill not far from where they are found, while others were brought from the cliffs three fourths of a mile away. In the quarries at the cliffs there are several stones partly hewn, and there are two roads still to be traced, along which the blocks were drawn. The evidences are that the stones were roughly cut at the quarries, then drawn along the roads, and fitted in their places on arriving at the fortress. [Illustration: SALIENT ANGLE OF FORTRESS.] "To have a realizing sense of the size of the stones used in building the fortress of Cuzco, look at the picture of one of the salient angles of the wall, and the figure of the man leaning against it. Consider the man to be of ordinary stature, and you can readily compute the height of the stone. [Illustration: ROAD LEADING TO FORTIFIED HILL.] "In the neighborhood of Cuzco there are many other remains of palaces, temples, and fortresses, but we have said enough to give you an idea of what the ancient Peruvians left behind them. In some of the native villages the houses are the same that were inhabited four or five hundred years ago; the roofs have been renewed, but the walls remain unchanged. In many instances the natives have erected hovels by the side of the ancient houses, through their unwillingness to take the trouble to renew the roofs, which had been destroyed by time and the elements. [Illustration: ANCIENT DWELLING-HOUSE.] "The roads which the Incas built have been mostly allowed to go to decay, by their successors, though some parts of them are still in use. The new ones are far inferior to the old, and nothing better demonstrates the slovenly character of the invaders than a comparison of their wretched paths through the mountains with the paved tracks of the original possessors of the land. The Spaniards came in search of gold, and did not intend remaining; circumstances kept them here, but they were always looking for a speedy return to their native land, and made no effort to improve or even to preserve what they found on their arrival. Their descendants are still searching for treasures among the palaces of the Incas, and a visitor to the ruins in and around Cuzco can see, almost any day, men digging among the rubbish for the gold which is supposed to be concealed there." [Illustration: SPECIMEN OF CYCLOPEAN WALL.] As the youths finished their account of the wonderful city of Cuzco and its surroundings, the Doctor returned from his walk. They read to him what they had written; he gave his approval, with an intimation that it might be dull reading to some of their schoolmates, but was a necessary part of a narrative of travels in Peru. Fred suggested that anybody who did not like it was at liberty to skip a few pages, till he reached something more interesting. Frank was of the same opinion, and with this the manuscript was folded and laid away.
