As they sat round the fire later on they discussed their next move, and agreed that as the river was shallow they would cross it at once, and then follow it up stream. Should they find no landmarks answering to those on the map, they would then return and go down the stream.

Next morning they started again, with fifteen loaves done up in a blanket on one of the ponies. The journey was toilsome, for the river ran in places through gorges where the rocks rose sheer from its edge, and they were forced to make considerable detours, and to come down upon it again. They had traveled, they calculated, but eight miles up the stream, when they came upon a valley running east. A small stream ran down it, and fell into the river they were following.

"This looks a likely sort of place," Dave said; "it is the sort of valley a party exploring would be likely to follow. There is wood, water, and grass. Now for the landmarks."

They went on until they reached the spot where the stream fell into the river.

"We can't do better than camp here, Dave," 'Zekel said; "it has been a rough journey for the ponies, and they will be all the better for another good feed."

"All right," Dave agreed, "I don't see any signs of the landmarks, but they may be somewhere about. We will unsaddle the ponies. Boys, you may as well walk up the stream a bit. Keep your eyes open, but don't go very far away. Keep your rifles ready for use; there is no saying but what some prowling Indian may not have caught sight of us as we came along."

The boys unslung their rifles, which were strapped tightly to their backs—they were already loaded—and started up the valley. In a quarter of a mile they passed through the low wood which filled the bottom of the valley. In front of them was an open space, bright with long grass and flowers. In the center of this stood two large trees, one on either side of the stream. They hurried on, and when they reached the trees saw, to the northwest, two peaks, one nearer and lower than the other, in an exact line. As the direction was exactly that of the two dots on the map, they had no doubt whatever that they had hit the right spot. They returned at once with the news to the men. Dave had already lighted a fire, for in this sheltered valley there was little fear of the slight smoke it made being seen, broken up as it was in its passage through the leaves overhead.

"We have found the marks," Dick said, as they arrived. "We don't think there can be any mistakes about them."

"Have you? That is good," and the three men at once went on to the two trees.

"There is no doubt that is what was meant," Boston Joe said. "Wall, I am glad to see them—it shows, anyhow, that we are right in our guess-work as to the map, which we never felt quite sure of before, seeing them three peaks war the only thing we had to go on, and the marks might not have been meant for them arter all. Now the matter air clear and fixed, and we have only got to go ahead."
