"In that case there would be only one other thing to do," observed Roger, disconsolately; "which would be to kick him out of camp, and warn him, just as he did Lascelles, that if he ever allowed himself to be seen near the camp again it would be at his peril." "Mark my words, Roger, if we are lucky enough to catch the man in the act, that is what will happen to him. But, before he goes, he will listen to a ringing talk from Captain Lewis that will make his cheeks burn." "Yes, and not for all the money Lascelles ever owned would I want to have such a fine man as Captain Lewis tell me that, as a traitor to my trust, I had sunk down until I was beneath contempt. But I wonder, Dick, how he will manage to let them know about the rifles and ammunition in the supply tent?" "Depend on it the captain has that arranged cleverly enough," Dick declared, "and he will accomplish it without awakening any suspicion that it has been done for a purpose." "What shall we do next?" asked Roger. "Wait for his signal as arranged with us," explained Dick. "When we get that, it is our duty to slip out of camp without being noticed, and settle down in that patch of brush, just as he said. Later on, he will join us there, and bring Captain Clark with him." They sat there and exchanged words for quite a long time, while the evening waned, and some of the tired men, who had been poling or rowing all day, began to creep into the tents, or, it might be, under rude bough shelters, where they expected to sleep through the remainder of the night. "The time has come at last," said Dick, in a low tone. "Did you see Captain Lewis make the gesture he explained to us?" asked his chum. "Yes, and now let us see how smartly we can carry out our part of the game, as we laid it out in advance." After surveying the field, the boys concluded that, by pretending to settle down in a certain place, they could withdraw by degrees without being noticed, and come up in the rear of the patch of bushes marked by the commander as the meeting spot. This maneuver was accomplished with considerable skill, because both lads were well drilled in Indian ways, and could snake their way along the ground as well as any painted brave on the warpath, seeking to spy on the enemy's camp. In due time, therefore, they crept into the bushes, and settled down to await the coming of the two captains. Just as they expected, from their place of hiding it was possible to keep a close watch upon the supply tent, though the latter stood in the shadows, with the firelight playing on one side of it only. Slowly the minutes crept along. The boys rarely exchanged words, and then only in the lowest of whispers; nor did they make any sort of move, lest in some way keen eyes discover their presence amidst the bushes. It seemed ages before Roger pressed the arm of his cousin, and spoke in his ear. "Something moving behind us, Dick!"
