In all the square, however, and in those thoroughfares of the city which they could observe, was no sign of life and movement.

“It looks like a city of the dead,” said Jack. “If I didn’t know differently, I would believe we had stumbled upon an abandoned city. But the fortress certainly has occupants, as we have seen. What do you make of it, Dad?” he inquired, walking over toward his father.

Mr. Hampton shook his head, and Jack turned inquiringly to Don Ernesto. The latter looked thoughtful.

“There is a possibility,” he said, as one cudgeling his brains to recall something once known but long out of memory. “Yet—I don’t know—it seems foolish.”

“What?”

“That these descendants of the Incas should be keeping the great annual religious ceremony of their ancestors? Yet, it is the same time of year.”

“Oh, Father. The annual festival of the Sun?” cried Ferdinand.

Don Ernesto nodded.

“Tell us about it,” said Jack. “I’d like to learn all I can about these people.”

“Very well,” said Don Ernesto. “Sit down, and I’ll tell you what I can recall. The religion of the Peruvian Empire,” he continued, when all had found seats around him, “expressed the feelings of the people toward their heavenly protector and their earthly ruler. They worshipped the sun and adored the reigning Inca as his descendant upon earth. For the term of Inca, you will doubtless recall, did not apply to every member of the empire, but only to those of royal blood. The legend was that the sun looking down upon the savages took pity upon them for their mode of living, and sent to earth a son, Manco Capac, and a daughter, Mama Oello, children of his own, to civilize and instruct mankind. They came to earth near the Lake of Titicaca. He gave them a rod of gold and bade them go whither they pleased, but, to remember that when they came to a place where this rod should sink into the earth, that was the place at which he wished them to abide. The legend has it that the rod disappeared in the earth at Cusco. Therefore, there they stayed, bringing the savages together, instructing them, and building up the great city that afterwards became the capital of the empire.
