Another five minutes they entered a gorge so blocked with rocks that had fallen from above that they had the greatest difficulty in leading the horses over them.

"It could not be better," Dave said. "We can stop them here. Zeke, do you go on with Dick, see how far this goes, and what the chances are when we get out of it. If you can see any way of climbing the side of the valley come back and tell us. Then I reckon the best thing will be for you to take the horses down and go straight up, leaving Dick to tell us exactly where you have gone up; then, as soon as it is quite dark, we will be off and follow you; they won't be able to pick up the trail and will guess we have gone straight down the valley. Anyhow, it will give us another twelve hours' start."

Zeke nodded. "We may as well take the critters down at once," he said; "it may be two or three miles before we can find a place where we can get out of this valley, and there aint no use making two journeys of it."

Somewhat reluctantly Dick followed Zeke, driving the horses before them.

They had been gone but five minutes when he heard the crack of a rifle behind them.

"Do you think they are sure to be able to hold that place?"

"They are safe for some time, anyhow," Zeke said. "As soon as the redskins see they are brought to a stand they will draw off and wait till the bands that have gone up the other valleys join them. No doubt, as soon as they had made out our tracks again, they sent a kipple of men off to fetch them back, but I reckon they wouldn't have seen them till they got four or five miles down, and by that time the other bands would have been as much farther up the side-valleys, and the messengers would have a long ride before they overtook them—ten or twelve miles, maybe—and they would have all that to come down again, so they would be pretty well four hours before they had joined the first band, and in four hours it will be dark enough for Dave to draw off."

"There they go again!"

Shot after shot echoed among the cliffs. The gorge extended for another mile, and then widened rapidly. A mile and a half farther the sides were clad with trees, and the slope, although still steep, was, Zeke said, possible for horses to scramble up.

"They will go up there safe enough," he said, "five of them with nothing to carry, and the other four ain't heavy loaded. You see them two trees standing alone on the crest there?"

"I see them, Zeke."

"Well, that is to be your mark. You will make them out plainly enough in the moonlight. I shall be just down beyond them. I need not tell you to be keerful how you go when you get beyond the shelter of the trees below. Dave will know all about that. Now you can be off back again."

Dick started back at a run, and in less than half an hour joined the other three among the rocks.

"Found a place, lad?"

"Yes; they have started up."

"I am glad you are back. These fellows look as if they were going to make an attack on us. They are about five-and-twenty of them, and I guess they know as well as we do that it will be dark before their friends join them. However, I don't think they will make a rush; they will lose heart when three or four of their number get shot, and weaken when it comes to climbing these rocks in face of our six-shooters. Now, do you two lads keep below; get d............
