"But how does he know we have a canoe?"

"He does not know it, but he feels sure of it because our trail led straight to the lake, and we would not purposely come up against such a barrier, unless we knew of a way to cross it."

"That sounds like good logic. Of course when they return they'll make a much more thorough search of the lake's edge, and then they'd be likely to find us if we remained here."

"It is so, but perhaps the night will come before Tandakora, and then we'll take flight upon the lake."

They pushed their canoe back to the edge of the reeds, and watched the Indian boats pa.s.sing in single file northward, becoming smaller and smaller until they almost blended with the water, but both knew they would return, and in that lay their great danger. The afternoon was well advanced, but the sun was very brilliant, and it was hot within the reeds. Great quant.i.ties of wild fowl whirred about them and along the edges of the lake.

"No warriors are in hiding near us," said Tayoga, "or the wild fowl would fly away. We can feel sure that we have only Tandakora and his band to fear."

Robert had never watched the sun with more impatience. It was already going down the western arch, but it seemed to him to travel with incredible slowness. Far in the north the Indian boats were mere black dots on the water, but they were turning. Beyond a doubt Tandakora was now coming back.

"Suppose we go slowly south, still keeping in the shadow of the trees," he said. "We can gain at least that much advantage."

Fortunately the scattered fringe of reeds and bushes, growing in the water, extended far to the south, and they were able to keep in their protecting shadow a full hour, although their rate of progress was not more than one-third that of the Indians, who were coming without obstruction in open water. Nevertheless, it was a distinct gain, and, meanwhile, they awaited the coming of the night with the deepest anxiety. They recognized that their fate turned upon a matter of a half hour or so. If only the night would arrive before Tandakora! Robert glanced at the low sun, and, although at all times, it was beautiful, he had never before prayed so earnestly that it would go over the other side of the world, and leave their own side to darkness.

The splendor of the great yellow star deepened as it sank. It poured showers of rays upon the broad surface of the lake, and the silver of the waters turned to orange and gold. Everything there was enlarged and made more vivid, standing out twofold against the burning western background.

Nothing beyond the shadow could escape the observation of the Indians in the boats, and they themselves in Robert's intense imagination changed from a line of six light craft into a great fleet.

Nevertheless the sun, lingering as if it preferred their side of the world to any other, was bound to go at last. The deep colors in the water faded.

The orange and gold changed back to silver, and the silver, in its turn, gave way to gray, twilight began to draw a heavy veil over the east, and Tayoga said in deep tones:

"Lo, the Sun G.o.d has decided that we may escape! He will let the night come before Tandakora!"

Then the sun departed all at once, and the brilliant afterglow soon faded.

Night settled down, thick and dark, with the waters, ruffled by a light wind, showing but dimly. The line of Tandakora became invisible, and the two youths felt intense relief.

"Now we will start toward the northeastern end of the lake," said Tayoga.

"It will be wiser than to seek the shortest road across, because Tandakora will think naturally that we have gone that way, and he will take it also."

"And it's paddling all night for us," said Robert "Well, I welcome it."

They were interrupted by the whirring of the wild fowl again, though on a much greater scale than before. The twilight was filled with feathered bodies. Tayoga, in an instant, was all attention.

"Something has frightened them," he said.

"Perhaps a bear or a deer," said Robert.

"I think not. They are used to wild animals, and would not be startled at their approach. There is only one being that everything in the forest generally fears."

"Man?"

"Even so, Dagaeoga."

"Perhaps we'd better pull in close to the bank and look."

"It would be wise."

Robert saw that the Onondaga, with his acute instincts, was deeply alarmed, and he too felt that the wild fowl had given warning. They sent the canoe with a few silent strokes through the shallow water almost to the edge of the land, and, as it nearly struck bottom, two dusky figures rising among the bushes threw their weight upon them. The light craft sank almost to the edges with the weight, but did not overturn, and both attackers and attacked fell out of it into the lake.

Robert for a moment saw a dusky face above him, and instinctively he clasped the body of a warrior in his arms. Then the two went down together in the water. The Indian was about to strike at him with a knife, but the lake saved him. As the water rushed into eye, mouth and nostril the two fell apart, but Robert was able to keep his presence of mind in that terrible moment, and, as he came up again, he s.n.a.t.c.hed out his own knife and struck almost blindly.

He felt the blade encounter resistance, and then pa.s.s through it. He heard a choked cry and he shuddered violently. All his instincts were for civilization and against the taking of human life, and he had struck merely to save his own, but almost articulate words of thankfulness bubbled to his lips as he saw the dark figure that had hovered so mercilessly over him disappear. Then a second figure took the place of the first and he drew back the fatal blade again, but a soft voice said:

"Do not strike, Dagaeoga. I also have accounted for one of the warriors who attacked us, and no more have yet come. We may thank the wild fowl. Had they not warned us we should have perished."

"And even then we had luck, or your Tododaho is still watching over us. I struck at random, but the blade was guided to its mark."

"And so was mine. What you say is also proved to be true by the fact that the canoe did not overturn, when they threw themselves upon us. The chances were at least ninety-nine out of a hundred that it would do so."

"And our arms and ammunition and our deer?"

"All in the canoe, except the weapons that are in our belts."

"Then, Tayoga, it is quite sure that your Tododaho has been watching over us. But where is the canoe?"

Robert was filled with alarm and horror. They were standing above their knees in the water, and they no longer saw the little craft, which had become a veritable ship of refuge to them. They peered about frantically in the dusk and then Tayoga said:

"There is a strong breeze blowing from the land and waves are beginning to run on the water. They have taken the canoe out into the lake. We must swim in search of it."

"And if we don't find it?"

"Then we drown, but O Dagaeoga, death in the water is better than death in the fires that Tandakora will kindle."

"We might escape into the woods."

"Warriors who have come upon our trail are there, and would fall upon us at once. The attack by the two who failed proves their presence."

"Then, Tayoga, we must take the perilous chance and swim for the canoe."

"It is so, Dagaeoga."

Both were splendid swimmers, even with their clothes on, and, wading out until the water was above their waists, they began to swim with strong and steady strokes toward the middle of the lake, following with exactness the course of the wind. All the time they sought with anxious eyes through the dusk for a darker shadow that might be the canoe. The wind rose rapidly, and now and then the crest of a wave dashed over them. Less expert swimmers would have sunk, but their muscles were hardened by years of forest life--all Robert's strength had come back to him--and an immense vitality made the love of life overwhelming in them. They fought with all the powers of mind and body for the single chance of overtaking the canoe.

"I hope you see it, Tayoga," said Robert.

"Not yet," replied the Onondaga. "The darkness is heavy over the lake, and the mists and vapors, rising from the water, increase it."

"It was a fine canoe, Tayoga, and it holds our rifles, our ammunition, our deer, my buffalo robe, and all our precious belongings. We have to find it."

"It is so, Dagaeoga. We have no other choice. We truly swim for life. One could pray at this time to have all the powers of a great fish. Do you see anything behind us?"

Robert twisted his head and looked over his shoulder.

"I see no pursuit," he replied. "I cannot even see the sh.o.r.e, as the mists and vapors have settled down between. In a sense we're out at sea, Tayoga."

"And Ganoatohale is large. The canoe, too, is afloat upon its bosom and is, as you say, out at sea. We and it must meet or we are lost. Are you weary, Dagaeoga?"
