“If you gentlemen will relieve guard,” he said quietly, “I’ll see about breakfast.”

Soon after, as if nothing whatever had happened, they all sat down to a hearty meal, and that over, once more started upon their journey through the mountains; the Indians seeming more willing, and at the suggestion that the mules should rest for a day or two in that luxuriant pasturage, eagerly assuring the colonel, through Cyril, that for days to come they would find plenty, and that the road would be easier.

On hearing this, the colonel decided to go on, and soon found that the guide’s words were correct; for, during the next six days, they traversed smiling valleys, with grass and trees in abundance. Snowcapped hills rose high above them; but where they journeyed, they were in a beautiful temperate climate, with rich soil and abundance of flowers.

This part of their journey was delightful; for the way along the passes was easy, and the colonel, who was a dead shot, several times over added to their larder with his gun.

But they went on in no false security; for several times over they passed Indians, and were made fully aware of the fact that every mile they took was carefully watched, and that the leader of the expedition inspected no mountain shelf, cave, or patch of dwarf forest, without his acts being duly noted, though in no observant way.

Diego proved to be a perfect guide; and, making no objections now, he led them steadily on in a way which would have disarmed suspicion with some people; but the colonel was quietly on the alert, and went on examining plant, flower, and tree, at one time with all the patient care of a botanist; and at another time, when they were climbing some rugged shelf in a ravine, letting no mineral escape his observation.

And all the while the little party, though they made no sign, were perfectly well aware that they were being watched.

“Strikes me that when we’ve got it, they won’t let us take a simple lump of gold out of the place, Master Cyril.”

“No,” said the boy drily.

“But I mean some of the precious stones, Master Perry. I shall have them.”
