It was a hard test to endure, while the canoe with the four relentless warriors in it rowed about seeking them. Robert paid all the price of a vivid and extremely brilliant imagination. While those with such a temperament look far ahead and have a vision of triumphs to come out of the distant future, they also see far more clearly the troubles and dangers that confront them. So their nerves are much more severely tried than are those of the ordinary and apathetic. Great will power must come to their relief, and thus it was with Robert. His body quivered, though not with the cold of the water, but his soul was steady.

Although the wind sank, which was against them, the darkness increased, and the fact that two other trees were afloat within view, was greatly in their favor. It gave them comrades in that lazy drifting and diverted suspicion.

"If they conclude to make a close examination of our tree, what shall we do?" whispered Robert.

"We'll be at a great disadvantage in the water," the hunter whispered back, "but we'll have to get our rifles loose from their lashings and make a fight of it. I'm hoping it won't come to that."

The canoe approached the tree and then veered away again, as if the warriors were satisfied with its appearance. Certainly a tree more innocent in looks never floated on the waves of Lake George.

The three were masters of illusion and deception, and they did not do a single thing to turn the tree from its natural way of drifting. It obeyed absolutely the touch of the wind and not that of their hands, which rested as lightly as down upon the trunk. Once the wind stopped entirely and the tree had no motion save that of the swell. It wandered idly, a lone derelict upon a solitary lake.

Robert scarcely breathed when the canoe was sent their way. He was wholly unconscious of the water in which he was sunk to the shoulders, but every imaginative nerve was alive to the immense peril.

"If they return and come much nearer we must immerse to the eyes," whispered Willet. "Then they would have to be almost upon us before they saw us. It will make it much harder for us to get at our weapons, but we must take that risk too."

"They have turned," said Robert, "and here they come!"

It looked this time as if the savages had decided to make a close and careful inspection of the tree, bearing directly toward it, and coming so close that Robert could see their fierce, painted faces well and the muscles rising and falling on their powerful arms as they swept their paddles through the water. Now, he prayed that the foliage of the tree would hide them well and he sank his body so deep in the lake that a little water trickled into his mouth, while only the tips of his fingers rested on the trunk. The hunter and the Onondaga were submerged as deeply as he, the upper parts of their faces and their hair blending with the water. When he saw how little they were disclosed in the dusk his confidence returned.
