"They know now that we've given them the slip, don't they, Dick?" chuckled Roger, whom even the recent peril did not seem to have daunted. "They certainly do," answered the other. "But here is what seems to be another little rise on our left, Dick," observed Roger, as what looked like a secondary ridge arose between them and the star-studded heavens. "Yes, I've been noticing that for some little while now," Dick answered. "And I'm sure that just on the other side lies the level prairie that we want to reach soon." "Then we must cross over that divide; is that the way, Dick?" "When we come to a place where we can do it without exposing ourselves too much. Remember how I happened to discover the seventeen braves, Roger; though they would be too far away, perhaps, to see us crossing over. And here seems to be the right spot to make the attempt. I hope we find a trail for the horses, because they are not able to climb rocks as we can." A short time later they were slowly but steadily passing up from the little valley that lay like a swale between the two slight ridges. "This is all right, Dick," remarked Roger, when, after some toil, they managed to reach what seemed to be the pinnacle of the "hogback," as the border boys called such a ridge. "Yes, and if the going down is as easy, we can thank our stars," answered Dick. Before starting the descent he turned and looked long and earnestly in the direction whence those cries of disappointment had arisen a short time before. "There, what did I tell you?" he exclaimed; "look yonder, Roger, and you will see something queer." "Are they fireflies, Dick?" questioned the other; "they seem to look like it at this distance; and yet I can see that they do not come and go, but keep up a steady light." "If you were closer, Roger, you would see that they were strange lightning-bugs; for each one is a torch gripped in the hand of a red-skinned warrior, who bends over and follows the trail we made!" "Oh! then we didn't start away from our second camp any too soon, did we, Dick?" exclaimed the younger lad, breathlessly, as he watched the lights that really did look like flickering fireflies in the distance. "No; and now we'd better be getting off this high ground before they come close enough to discover us," Dick remarked. "But what is going to be the end of all this running about?" asked Roger. "Do we have to keep on the jump all night? See, the stars tell us it is even now close on midnight, for there is that other bright one just going to set. I've had two hours or more of sleep, but you haven't yet closed your eyes, Dick."
