"That may be, señor; but the valley may be a large one, and the hiding-place very difficult to find, so that even when the valley was known, it would need the guidance of the star to take us to the right place."
"That might be so, Dias, if it were a hidden treasure that we were looking for; but as, according to your account, it is simply an extraordinarily rich deposit in the river, I hardly see why the guidance of the star should be necessary when once the valley was known."
"That I cannot tell you, señor; but I am sure that it must be difficult to find, for the Spaniards searched everywhere for gold, and although the records of most of their discoveries still exist, there is no mention of such a find, nor is there is any word of it among the Indian traditions."
A week before the appointed date they found themselves in the neighbourhood where they felt sure the cleft must lie. Mount Tinta was twenty miles in front of them, and from that point a range of mountains trended off almost at right angles to that which they were following. One lofty peak some thirty miles to the south-east rose above another.
"I believe that that is the peak," Dias said.
"I don't see any signs of a cleft in it, Dias."
"No, señor; it is a very narrow one."
The next day they halted at the mouth of another valley, and as they unloaded the mules, Harry exclaimed: "See, Dias, there is a cleft in that peak! From here it looks as if it were a mere thread, and as if some giant had struck a mighty sword-cut into it."
"That is right. Sure enough, señor, this must be the valley. Now, let us look about for the serpent."
The search did not take them long. An isolated rock rose a quarter of a mile from the mouth, and on this was a rude representation of a serpent. The next morning they explored the valley thoroughly to a point where, five miles higher, it ceased abruptly, the rocks closing in on either side, and the stream coming down in a perpendicular fall from a point some eighty feet above them. Going down the river, they washed the gravel again and again, but without obtaining even as much gold as they had found several times before.
