He lit his pipe and went upstairs. José went off to the mules, and Bertie descended the ladder, and strolled round what they called the courtyard, looking for eggs among the rocks and in the tufts of grass growing higher up. Dias scattered a few handfuls of maize to the chickens and then assisted Maria to catch two of them; after which he descended the ladder and sat down gloomily upon a stone. He had become more and more depressed in spirits as the search became daily more hopeless; and although he worked as hard as anyone, he seldom spoke, while Harry and his brother often joked, and showed no outward signs of disappointment. An hour passed, and then Harry appeared suddenly at the window.
"Bertie, Dias, come up at once, I have an idea!"
They ran to the ladder and climbed up. The excitement with which he spoke showed that the idea was an important one. "Now, Dias," he broke out as they joined him, "we know, don't we, that a part of the Incas' treasure was sent off by boat, and the belief of the Indians was that it was never heard of again."
"That is so, señor. There was certainly a storm the day after it started, and, as I have told you, it was never heard of again. Had it been, a report of it would surely have come down."
"I believe, Dias, that the boat was dashed to pieces against that line of rocks outside the entrance to the passage. We have reason to believe that the people here were expecting the treasure to arrive, and had the entrance to the cave in readiness to receive it. Certainly no better place could have been chosen for concealment. The boat may have been coming here when the storm broke and drove them towards the shore. They probably attempted to gain the mouth of the cove, but missed it, and were dashed to pieces against the rocks. The Indians on guard here no doubt saw it, and would be sure that the heavy sacks or boxes containing the gold would sink to the bottom. They would lie perfectly secure there, even more secure than if they had been removed and placed in the cave, and could always be recovered when the Spaniards left, so they were content to leave them there. Still, they obeyed the orders they had received to keep watch for ever over the treasure, and to do so knocked that strange hole through the wall and always kept two men on guard there.
"So it must have gone on. They and those who succeeded them never wavered. Doubtless they received food from their friends outside, or some of them went out, as you have done, to fetch it in. Then came a time when, for some reason or other—doubtless, as I supposed before, when the Spaniards swept pretty nearly all the natives up to work in the mines, and they themselves dared not issue out—the attempt to get food was made, when too late, by the men whose skeletons we found on the steps when we first came here; and the rest were all too feeble to repeat the experiment, and died—the two sentinels at their post, the rest in the room where we found them."
"Hurrah!" Bertie shouted, "I have no doubt you have hit it, Harry. I believe, after all, that we are going to find it. That is splendid! I shall dance at your wedding, Harry, which I had begun to think I never should do."
"Don't be a young ass, Bertie. It is only an idea, and we have had several ideas before, but nothing has come of them."
"Something is going to come of this, I am convinced; I would bet any money on it. Well, shall we go and have a trial at once?"
"What do you think, Dias?" Harry said, paying no attention to Bertie's last remark.
