"When you think of that it is not surprising that these poor ignorant natives still have implicit faith in the traditions of their ancestors. It is possible that this old place is still inhabited by Indians, who have been its guardians for ages, and if not now, may have had charge of it long after the Spaniards came here, and murdered any who ventured to approach the place. We know that the tradition of the gold valley has been faithfully maintained in the family of Dias; this may also be the case in the family to which the guardianship of this old place was entrusted, but to my mind it is less likely. In the case of the gold valley there was nothing for those in the secret to do but to hold their tongues; but to supply guardians to this place from generation to generation must have been a much more irksome task, and it may have been abandoned, either from the dislike of those who had to spend their lives in such a monotonous business, or by their families dying out. I certainly don't want to have a fight with men who are only following orders passed down to them for hundreds of years. If they attack us, we shall have to fight; but I sincerely trust that we may find the place deserted, for, fight or no fight, I mean to get the treasure if it is there."
"I should think so," Bertie agreed. "The treasure is absolutely of no use to them, and may be no end of use to you."
"To both of us, Bertie. If there is a treasure, you may be sure it is a large one, ample for both of us, and to spare. Of course we shall have trouble in getting it away—the gold would be invaluable to any of these rascally adventurers who are a curse to Peru. I really want to see the place, even putting aside the question of the treasure, for it must have been extraordinarily well hidden if the Spaniards never came upon it; and I think there can be no doubt whatever that in this respect the traditions must be true. The whole thing would have been upset if the Spaniards had once paid a visit there, for, from what we saw at Pachacamac and Cuzco, they spared no exertions whatever to root out likely hiding-places. The treasure, if there is one, will be difficult to find, but I have got nearly a year yet, and if necessary I will spend the whole of it in digging. Dias could go and get provisions for us. Of course he must not always go to the same place. Sometimes he can go up to Huaura, sometimes down to Chancay or Ancon. This place, he has told me, lies a mile or two south of the Salinas promontory, which would partly account for its escaping notice, for the road from Huaura, as we see on the map, skirts the foot of the hill, and goes straight on to Chancay and Ancon, and there is no earthly reason why anyone should go out to the promontory. People here don't leave the roads and travel eight or ten miles merely to look at the ocean, especially when by following the straight line they would see it without trouble. Well, we have both had hard work during the past year, what with felling trees to make bridges, chopping logs for fires, making roads practicable by moving rocks out of the way, occasionally using our picks where Dias thought that there was a lode, and carrying mules' burdens up and down steep places.
"Altogether it has been a sort of backwoodsman's life, and if there are treasure-vaults in this place I think we shall be able to get at them, however thick and heavy the stones may be on the top of them."
"I am game," Bertie said. "There is a lot more excitement in working when possibly a treasure lies under your feet than in chopping away at trees, some of which are so hard as almost to turn the edge of an axe. The place cannot be very large, so it won't take us very long if we are obliged to tear up every foot of it. I suppose there cannot be above three feet of stone over the mouths of any of these vaults."
"I think, Bertie, that when we have once investigated the place and settled on our plans, we had better send Dias and José down to Callao to get three or four kegs of powder and some boring tools, besides a supply of provisions. We should get on a lot faster with these than with only pickaxes. We shall want a couple of strong iron crowbars for lifting slabs of stone, and of course some fuse for the mines."
"We should have to be careful not to put too much powder in, so as not to bring the whole thing down about our ears."
"Oh, we should not want to make a mine of that sort, but only to blast the stone as they do in quarries and mines. We should have to make a hole to begin with, by means of our picks and crowbars, in one corner of the room, two or three feet wide; then we must make a couple of holes the size of the boring tool, a foot or so away, according to the hardness of the ground, put in charges and fire them, and in that way blow down the rock into the hole we had made; and so we should go on until we had done the whole floor. Of course, the bigger the hole we first make—that is to say, the wider the face it has—the easier we shall blow the stone down afterwards. I have watched them blasting stone at Portland, and at some galleries they were making at Gibraltar, and I know pretty well how it is done. Of course it is hard work driving the borers down, for that we shall want two or three sledges of different weights. It will make our arms ache at first, but after a week or two we shall be able to stick to it fairly well. Now we had better turn in. We shall start at daybreak tomorrow. It will take us two hours to reach the spot from which Dias said we could see the place, and another three hours to get to the castle. That will give us a long afternoon to take our first look over it."
"There, señor," Dias said, when at eight o'clock in the morning they stopped on a projecting spur of the hill, "that is the castle!"
From where they stood they could see that the ground fell away into what was at first a mere depression, but gradually deepened into a valley half a mile wide. Still farther down the sides became more precipitous, and in the distance the valley was closed in by rock walls, and appeared to come to an end. That it did not do so was evident from a streak of bright green in the centre of the valley, showing that a small stream must run down it. From the point at which they stood they could see the level line of the plateau near the cliff facing the sea, and on the surface of this a dark zigzag line marked the course of the ravine. Then, when apparently close to the termination of the flat land by the cliffs, the dark streak widened out somewhat. Through a small but powerful telescope which Harry carried he could make out distinctly the upper part of what might be a house.
