They bore with them as they advanced from the neighbourhood of Lake Titicaca a golden wedge, and were directed to take up their abode at the spot where this sacred emblem should sink easily into the ground. This happened in the Valley of Cuzco; the wedge of gold sank into the earth and disappeared for ever, and Manco Capac settled down to teach the men of the land the arts of agriculture, while Mama Ocllo showed the women how to weave and spin. Under these wise and benevolent rulers the community grew and spread, absorbing into itself the neighbouring tribes, and overrunning the whole tableland. The city of Cuzco was founded, and, under the successors of the Children of the Sun, became the capital of a great and flourishing monarchy. In the middle of the fifteenth century the famous Topa Inca Yupanqui led his armies across the terrible desert of Atacama, and, penetrating to the southern region of Chili, made the river Maule the boundary of his dominions, while his son, Huayna Capac, who succeeded him, pushed his conquests northward, and added the powerful kingdom of Quito to the empire of Peru. The city of Cuzco was the royal residence of the Incas, and also the 'Holy City,' for there stood the great Temple of the Sun, the most magnificent structure in the New World, to which came pilgrims from every corner of the empire. [Illustration: MANCO CAPAC AND MAMA OCLLO HUACO, THE CHILDREN OF THE SUN, COME FROM LAKE TITICACA TO GOVERN AND CIVILISE THE TRIBES OF PERU] Cuzco was defended on the north by a high hill, a spur of the Cordilleras, upon which was built a wonderful fortress of stone, with walls, towers, and subterranean galleries, the remains of which exist to this day and amaze the traveller by their size and solidity, some of the stones being thirty-eight feet long by eighteen broad, and six feet thick, and so exactly fitted together that, though no cement was used, it would be impossible to put the blade of a knife between them. As the Peruvians had neither machinery, beasts of burden, nor iron tools, and as the quarry from which these huge blocks were hewn lay forty-five miles from Cuzco, over river and ravine, it is easy to imagine the frightful labour which this building must have cost; indeed, it is said to have employed twenty thousand men for fifty years, and was, after all, but one of the many fortifications established by the Incas throughout their dominions. Their government was absolutely despotic, the sovereign being held so far above his subjects that even the proudest of the nobles only ventured into his presence barefooted, and carrying upon his shoulders a light burden in token of homage. The title of Inca was borne by all the nobility who were related to the king, or who, like himself, claimed descent from the Children of the Sun; but the crown passed from father to son, the heir being the eldest son of the 'coya,' or queen. From his earliest years he was educated by the
