rafts remained close together for a while, but as the current quickened and was more skillfully taken advantage of by Jeff, the larger raft gained considerable headway, gradually widening the gap between the two.
All day they drifted. From time to time Joe and Jim waved their hands to the girls; but the greater portion of their attention was given to quieting the horses. Mose, Joe's big white dog, retired in disgust to the hut, where he watched and dozed by turns. He did not fancy this kind of voyaging. Bill strained his sturdy arms all day on the steering-oar.
About the middle of the afternoon Joe observed that the hills grew more rugged and precipitous, and the river ran faster. He kept a constant lookout for the wall of rock which marked the point of danger. When the sun had disappeared behind the hills, he saw ahead a gray rock protruding from the green foliage. It was ponderous, overhanging, and seemed to frown down on the river. This was Shawnee Rock. Joe looked long at the cliff, and wondered if there was now an Indian scout hidden behind the pines that skirted the edge. Prominent on the top of the bluff a large, dead tree projected its hoary, twisted branches.
Bill evidently saw the landmark, for he stopped in his monotonous walk to and fro across the raft, and pushing his oar amidships he looked ahead for the other raft. The figure of the tall frontiersman could be plainly seen as he labored at the helm.
The raft disappeared round a bend, and as it did so Joe saw a white scarf waved by Nell.
Bill worked the clumsy craft over toward the right shore where the current was more rapid. He pushed with all his strength, and when the oar had reached its widest sweep, he lifted it and ran back across the raft for another push. Joe scanned the river ahead. He saw no rapids; only rougher water whirling over some rocks. They were where the channel narrowed and ran close to the right-hand bank. Under a willow-flanked ledge was a sand-bar. To Joe there seemed nothing hazardous in drifting through this pass.
"Bad place ahead," said Bill, observing Joe's survey of the river.
"It doesn't look so," replied Joe.
"A raft ain't a boat. We could pole a boat. You has to hev water to float logs, an' the river's run out considerable. I'm only afeerd fer the horses. If we hit or drag, they might plunge around a bit."
When the raft passed into the head of the bend it struck the rocks several times, but finally gained the channel safely, and everything seemed propitious for an easy passage.
But, greatly to Bill's surprise, the wide craft was caught directly in the channel, and swung round so that the steering-oar pointed toward the opposite shore. The water roared a foot deep over the logs.
"Hold hard on the horses!" yelled Bill. "Somethin's wrong. I never seen a snag here."
The straining mass of logs, insecurely fastened together, rolled and then pitched loose again, but the short delay had been fatal to the steering apparatus.
Joe would have found keen enjoyment in the situation, had it not been for his horse, Lance. The thoroughbred was difficult to hold. As Bill was making strenuous efforts to get in a lucky stroke of the oar, he failed to see a long length of grapevine floating like a brown snake of the water below. In the excitement they heeded not the barking of Mose. Nor did they see the grapevine straighten and become taut just as they drifted upon it; but they felt the raft strike and hold on some submerged object. It creaked and groaned and the foamy water surged, gurgling, between the logs.
Jim's mare snorted with terror, and rearing high, pulled her halter loose and plunged into the river. But Jim still held her, at risk of being drawn overboard.
"Let go! She'll drag you in!" yelled Joe, grasping him with his free hand. Lance trembled violently and strained at the rope, which his master held with a strong grip.
CRACK!
The stinging report of a rifle rang out above the splashing of the water.
Without a cry, Bill's grasp on the oar loosened; he fell over it limply, his head striking the almost submerged log. A dark-red fluid colored the water; then his body slipped over the oar and into the river, where it sank.
"My God! Shot!" cried Jim, in horrified tones.
He saw a puff of white smoke rising above the willows. Then the branches parted, revealing the dark forms of several Indian warriors. From the rifle in the foremost savage's hand a slight veil of smoke rose. With the leap of a panther the redskin sprang from the strip of sand to the raft.
"Hold, Jim! Drop that ax! We're caught!" cried Joe.
"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
