"That is excellent as far as it goes, if we happen to be in the right valley at the time, Dias, but it would not help us in the slightest if we were in any other valley. And we should have to wait a year before trying in another place."

"Yes, señor, but there are marks on the rocks of a particular kind. There are marks on rocks in other valleys, so that these should not be distinguished by Spaniards searching for the place. I should know the marks when I saw them."

"Then in that case, Dias, the star would not be of much use to us."

"I know not how that might be, señor, but as these instructions have been handed down from the time when the Spaniards arrived, it must surely in some way be useful, but in what way I cannot say."

"At any rate, Dias, what with those marks you speak of, and the star, it will be hard if we cannot find it. I suppose you are sure that the place is rich if we do light upon it?"

"Of that there can be no doubt, señor. Tradition says that it was the richest spot in the mountains, and was only worked when the king had need of gold, either for equipping an army or on some special occasion. At such a time it would be worked for one month, and then closed until gold was again required. However, as we go that way we shall explore other valleys. Gold is found more or less in all of them. Possibly we may find some rich spot which we can fall back upon if we fail in our search."

"But I hardly see how we can fail, with the star and those marks on the rocks to aid us."

"The marks may have disappeared, señor, and in that case we may not be in the right spot when the star rises; or again, the Incas may have closed the approach in some way to make the matter sure. I cannot promise that we shall find the gold; but I shall do my best with the knowledge that has come down to me. If I fail, we must try in other directions. When the Spaniards came, forty thousand of the Incas' people left Cuzco and the neighbouring towns, and journeyed away down the mountains and out to the west. Since then no reliable news concerning them has been heard, but rumours have from time to time come from that direction to the effect that there is a great and wealthy city there. I say not that if we failed here we should attempt to find it. The dangers from the savages would be too great. There would be great forests to traverse, many rivers to be crossed. We might travel for years without ever finding their city. When we got there, we might be seized and put to death, and if we were spared we might not be able to make off with the treasure. I mention it to show that gold may be found in many other places besides this valley we are seeking."

"I quite agree with you, Dias, that unless we could get some indication of the position of this city, if it now exists, it would be madness to attempt to search for it. I want gold badly, but I do not propose that we should all throw away our lives in what would be almost a hopeless adventure. Even if I were ready to risk my own life on such a mad enterprise, I would not ask others to do the same."

Crossing the stream, they made their way down through the forest. It was toilsome work, as they often had to clear a way with axes through the undergrowth and tangle of creepers. But at noon they reached level ground. The heat was now intense, even under the trees, and the air close and oppressive. On the way down Harry shot a wild turkey. When they halted, this was cut up and broiled over a fire, and after it had been eaten all lay down and slept for two or three hours.
