And so, because of greed, Pizzara had acted as an instrument to save their lives and then had actually sacrificed his own and those of his natives; and those who had been, under his revolver, actually beasts of burden, became carriers of their own treasure.

And carry it they did, with no complaint, for the secret way which they traversed was by no means as terrible as that by which they had come. The Inca’s way was cleverly chosen, cleverly hidden. But it was a very usable and easy way compared to the usual mountain passes.

One afternoon, as the sun was beginning to touch the tops of the Westward hills toward which the party now faced, they came to a narrow valley across which, far above, a swinging, osier-supported bridge was hung. But they did not cross the bridge; they went across the bottom of the valley and into a fissure in the rock that anyone would consider just one more cave, broken in there by Nature.

Nevertheless, it was not a cave but the opening into a great cleft in the virgin rock. Above them on both sides towered vast, steep granite slabs: their way lay between them.

Presently they came to steps, steep as a ladder almost, but firmly cut and shaped slightly downward at the inward side so that the wear of use leveling off the outer edge would not for centuries make the steps dangerous.

Up these they toiled, clinging dizzily, roped together, but not in any real danger. Mr. Gray, even, in spite of the toilsome journey, was in high spirits and, with many a rest but with a dauntless heart, he finally reached the top step and sat with his companions for a rest.

Soon they were off again: this time for only a short distance through a cleft; and when they emerged Cliff and Nicky gave a regular Indian war-whoop!

“See where we are?” shouted Cliff. “Look—yonder is the hut where I caught Huayca! There is the ledge where he watched our camp. This is the place, Father, where we lost the map and all——”

Sure enough! The Inca secret way had brought them out at almost the end of their journey; a few days and they would be in Cuzco, their adventures over!

That would have been the case if Huayca had not gone for a walk in the secret pass the day after the attack on Pizzara.
