"Mebbe so an' mebbe not," said Tom Ross. "My eyes ain't so bad and this bein' a good place to look from I think I see a canoe over thar right under the fur shore uv the Ohio. Jest look along thar, Henry, whar the bank kinder rises up." The point that Tom indicated was at least a mile away, but Henry agreed with him that a shape resembling a canoe lay close to the bank. Shif'less Sol and the others inclined to the same belief. "If so, it's a scout boat watching us," said Paul, "and Timmendiquas himself may be in it." Henry shook his head. "It isn't likely," he said. "Timmendiquas knows all that he wants to know, and is now going northeastward as fast as he can. But his warriors are there. Look! You can see beyond a doubt now that it is a canoe, and it's going up the river at full speed." The canoe shot from the shadow of the bank. Apparently it contained three or four Indians, and they had strong arms. So it sped over the water and against the current at a great rate. "They've seen all they want to see to-night," said Henry, "but that canoe and maybe others will be watching us all the way." A half hour later a light appeared in the northern woods and then another much further on. Doubtless the chain was continued by more, too far away for them to see. The men in the main camp saw them also, and understood. Every foot of their advance would be watched until the Indian army grew strong enough, when it would be attacked. Yet their zeal and courage rose the higher. They begged Clark to start again at dawn that no time might be lost. Boone joined the five under the tree. "You saw the lights, didn't you, boys?" he said. "We saw them," replied Henry, "and we know what they mean. Don't you think, Mr. Boone, that for a while the most dangerous part of the work will fall on you?" "Upon those with me an' myself," replied Boone in his gentle manner, "but all of us are used to it." For two successive nights they saw the fiery signals on the northern shore, carrying the news into the deep woods that the Kentucky army was advancing. But they were not molested by any skirmishers. Not a single shot was fired. The fact was contrary to the custom of Indian warfare, and Henry saw in it the wisdom and restraint of Timmendiquas. Indians generally attack on impulse and without system, but now they were wasting nothing in useless skirmishing. Not until all the warriors were gathered, and the time was ripe would Timmendiquas attempt the blow. It gave the little white army a peculiar feeling. The men knew all the time that they were being watched, yet they saw no human being save themselves. Boone's scouts found the trail of Indians several times, but never an Indian himself. Yet they continued their patient scouting. They did not intend that the army should fall into an ambush through any fault of theirs. Thus they proceeded day after day, slowly up the river, replenishing their supplies with game which was abundant everywhere.
