"It's that Indian from the fort!" gasped Jim.
The stalwart warrior was indeed Silvertip. But how changed! Stripped of the blanket he had worn at the settlement, now standing naked but for his buckskin breech-cloth, with his perfectly proportioned form disclosed in all its sinewy beauty, and on his swarthy, evil face an expression of savage scorn, he surely looked a warrior and a chief.
He drew his tomahawk and flashed a dark glance at Joe. For a moment he steadily regarded the young man; but if he expected to see fear in the latter's face he was mistaken, for the look was returned coolly.
"Paleface steal shirt," he said in his deep voice. "Fool paleface play—Silvertip no forget."
Chapter V.
Silvertip turned to his braves, and giving a brief command, sprang from the raft. The warriors closed in around the brothers; two grasping each by the arms, and the remaining Indian taking care of the horse. The captives were then led ashore, where Silvertip awaited them.
When the horse was clear of the raft, which task necessitated considerable labor on the part of the Indians, the chief seized the grapevine, that was now plainly in sight, and severed it with one blow of his tomahawk. The raft dashed forward with a lurch and drifted downstream.
In the clear water Joe could see the cunning trap which had caused the death of Bill, and insured the captivity of himself and his brother. The crafty savages had trimmed a six-inch sapling and anchored it under the water. They weighted the heavy end, leaving the other pointing upstream. To this last had been tied the grapevine. When the drifting raft reached the sapling, the Indians concealed in the willows pulled hard on the improvised rope; the end of the sapling stuck up like a hook, and the aft was caught and held. The killing of the helmsman showed the Indians' foresight; even had the raft drifted on downstream the brothers would have been helpless on a craft they could not manage. After all, Joe thought, he had not been so far wrong when he half fancied that an Indian lay behind Shawnee Rock, and he marveled at this clever trick which had so easily effected their capture.
But he had little time to look around at the scene of action. There was a moment only in which to study the river to learn if the unfortunate raftsman's body had appeared. It was not to be seen. The river ran swiftly and hid all evidence of the tragedy under its smooth surface. When the brave who had gone back to the raft for the goods joined his companion the two hurried Joe up the bank after the others.
Once upon level ground Joe saw before him an open forest. On the border of this the Indians stopped long enough to bind the prisoners' wrists with thongs of deerhide. While two of the braves performed this office, Silvertip leaned against a tree and took no notice of the brothers. When they were thus securely tied one of their captors addressed the chief, who at once led the way westward through the forest. The savages followed in single file, with Joe and Jim in the middle of the line. The last Indian tried to mount Lance; but the thoroughbred would have none of him, and after several efforts the savage was compelled to desist. Mose trotted reluctantly along behind the horse.
