"Two or three hundred, I should think. Your legends are evidently true, Dias. There was a party left here to keep strangers from entering this place. Now, before we go farther, let us think this out. We will sit down on the ledge of the window. But before we do so, take a good look at their arms and skulls, Dias. You have often been with travellers to the ruins; let us hear what you say."
Dias, who was now assured that he had only to deal with human beings, examined them carefully, looking at the ornaments that still hung round their necks, and then said: "They are not the old people, señor; these were Incas."
"That is an important point; now let us see how this is to be explained. Now," he said, as they sat down, "it is clear that the Incas did know this building. They may have discovered treasures here or they may not; but it would certainly seem that they were as anxious as the Chimoos had been to keep its existence a secret, and it is certain that they must have had some interest in doing so. We have reason to believe that the Spaniards at least did not know of it. There is no doubt whatever that these men were not killed in fight; on the contrary, their sitting position proves that they died quietly, and probably at the same time. We see no signs of food; we may find some as we search the place. If we do not, we must take it that they either died from an outbreak of some epidemic or from hunger. And it is quite probable that the two skeletons on the steps were two of their companions who were going out to seek for food, and that they fell from weakness; one clearly died in the act of trying to lift the other. What do you think of that, Dias?"
"I think that what you say is likely. But why should they have died from hunger?"
"It is probable that others were in the secret, and were in the habit of bringing provisions to them, and perhaps of relieving them at certain periods. We know that there were fierce battles in the early times of the Spaniards. In one of these battles the whole of those who were acquainted with the secret may have fallen. Or it may have been earlier after the conquest had been completed, when the Spaniards drove tens of thousands of men to work as slaves in the mines. The people here may have remained at their post, hoping for relief until it was too late. Two of the strongest may have started at last, but have been too weak to climb the steps, and died there. Their comrades may have never known their fate, but have sat down to die here, as you see. I should think it probable that the second of my suggestions is likely to be the right one, and that this did not take place until perhaps a hundred years after the arrival of the Spaniards, otherwise those legends of men who came near this place being killed would never have been handed down. If all this is as I suggest, either the Incas knew that the Chimoos had buried treasure here, or they themselves buried some, although, as you say, there is no tradition of treasure having been taken here. But it is possible that that treasure ship, which undoubtedly sailed from some place along the coast and was never again heard of, really came here; that her treasure was landed, and the vessel then destroyed. In either case, there is strong reason for hope that there is treasure somewhere in this castle if we can but find it."
"We will find it," Bertie said confidently. "What you say must be true. These Indians would never have been fools enough to sit here and die without some good reason for it. Well, I vote that before we do anything else we clear these bones out."
"We can do that the first thing to-morrow morning, Bertie. We can't just throw them out of the window. The bones are of men who died doing their duty to their country. We will leave them as they are to-day, and to-morrow we will bring up one of the big leather bags, place the bones in it, and take them down into the valley and bury them."
"Then you won't sleep here to-night, Harry?"
"No; I have not a shadow of superstition, but I do not think it would be lively here with those things at the end of the room. Now, let us look about a bit.
"This was evidently the great hall of the place; do you not think so, Dias?"
