The third link would be one of great difficulty, much harder than the bringing of the fire, and that was the reason why he was considering so well. He could discern the figures of three of the sentinels on land. Two of them were brawny warriors naked to the waist, and painted heavily. The third was quite young, younger than himself, a mere boy, perhaps on his first war path. Henry understood the feelings of hope and ambition that probably animated the Indian boy and he trusted that they would not come into conflict. The sentinels were walking about, and when the one nearest him turned and moved away he gathered up quickly fallen brushwood which lay kiln-dry at the river's brink. Then he hid his rifle, other weapons and ammunition in the grass. For a brief space he must go unarmed, because he could not be cumbered in an effort to keep them dry. Carrying the powder horn, the dry sticks and the one lighted at the end, he dropped silently into the water and managed with one arm to swim the few feet that separated him from the canoe. Then he passed around it, putting it between him and the land, and carefully lifted everything inside. He knew that the dry wood would burn fast when he placed the torch against it, and he put the horn full of powder very near. Then he sank low in the water behind the canoe, and listened until he heard the faint sputter of the fire in the dry wood. Now new difficulties arose. He must time everything exactly, and for the sake of his enterprise and his own life he must keep the Indian alarm from coming too soon. The sputtering was not yet loud enough for the warriors on the bank to hear it, and he ventured to rise high enough for another look over the edge of the canoe. In two minutes, he calculated, the fire would reach the powder horn. Then he drew from his belt his hunting knife, the only weapon that he had not discarded, and cut the withe that held the canoe. Burying himself in the water to the nose he sent his fire ship down the stream toward the two scows intending for it to enter just between them. Now he needed all his skill and complete command over his will. The sputtering of the fire increased, and he knew that it was rapidly approaching the horn of powder. The flesh had an almost irresistible desire to draw away at once and swim for life, but an immense resolution held his body to its yet uncompleted task. The canoe was moving with such a slight ripple that not an Indian sentinel had yet heard, but when it was within ten yards of its destination one happened to look over the river and see it moving. There would have been nothing curious in a canoe breaking its slender thong and floating with the current, but this one was floating against it. The Indian uttered a surprised exclamation and instantly called the attention of his comrades.
