At that cry the exhausted boy in the snow staggered to his feet, and with an answering shout which came but faintly to the ears of the Indian, resumed his flight across the lake. Two or three minutes later Wabi came up beside him.
"Can you make it, Rod?" he cried.
The other made an effort to answer, but his reply was hardly more than a gasp. Before Wabi could reach out to support him he had lost his little remaining strength and fallen for a second time into the snow.
"I'm afraid—I—can't do it—Wabi," he whispered. "I'm—bushed—"
The young Indian dropped his rifle and knelt beside the wounded boy, supporting his head against his own heaving shoulders.
"It's only a little farther, Rod," he urged. "We can make it, and take to a tree. We ought to have taken to a tree back there, but I didn't know that you were so far gone; and there was a good chance to make camp, with three cartridges left for the open lake."
"Only three!"
"That's all, but I ought to make two of them count in this light. Here, take hold of my shoulders! Quick!"
He doubled himself like a jack-knife in front of his half-prostrate companion. From behind them there came a sudden chorus of the wolves, louder and clearer than before.
"They've hit the open and we'll have them on the lake inside of two minutes," he cried. "Give me your arms, Rod! There! Can you hold the gun?"
He straightened himself, staggering under the other's weight, and set off on a half-trot for the distant tamaracks. Every muscle in his powerful young body was strained to its utmost tension. Even more fully than his helpless burden did he realize the peril at their backs.
Three minutes, four minutes more, and then—
A terrible picture burned in Wabi's brain, a picture he had carried from boyhood of another child, torn and mangled before his very eyes by these outlaws of the North, and he shuddered. Unless he sped those three remaining bullets true, unless that rim of tamaracks was reached in time, he knew what their fate would be. There flashed into his mind one last resource. He might drop his wounded companion and find safety for himself. But it was a thought that made Wabi smile grimly. This was not the first time that these two had risked their lives together, and that very day Roderick had fought valiantly for the other, and had been the one to suffer. If they died, it would be in company. Wabi made up his mind to that and clutched the other's arms in a firmer grip. He was pretty certain that death faced them both. They might escape the wolves, but the refuge of a tree, with the voracious pack on guard below, meant only a more painless end by cold. Still, while there was life there was hope, and he hurried on through the snow, listening for the wolves behind him and with each moment feeling more keenly that his own powers of endurance were rapidly reaching an end.
For some reason that Wabi could not explain the hunt-pack had ceased to give tongue. Not only the allotted two minutes, but five of them, passed without the appearance of the animals on the lake. Was it possible that they! had lost the trail? Then it occurred to the Indian that perhaps he had wounded one of the pursuers, and that the others, discovering his injury, had set upon him and were now participating in one of the cannibalistic feasts that had saved them thus far. Hardly had he thought of this possibility when he was thrilled by a series of long howls, and looking back he discerned a dozen or more dark objects moving swiftly over their trail.
Not an eighth of a mile ahead was the tamarack forest. Surely Rod could travel that distance!
"Run for it, Rod!" he cried. "You're rested now. I'll stay here and stop 'em!"
He loosened the other's arms, and as he did so his rifle fell from the white boy's nerveless grip and buried itself in the snow. As he relieved himself of his burden he saw for the first time the deathly pallor and partly closed eyes of his companion. With a new terror filling his own faithful heart he knelt beside the form which lay so limp and lifeless, his blazing eyes traveling from the ghastly face to the oncoming wolves, his rifle ready in his hands. He could now discern the wolves trailing out from the spruce forest like ants. A dozen of them were almost within rifle-shot. Wabi knew that it was with this vanguard of the pack that he must deal if he succeeded in stopping the scores behind. Nearer and nearer he allowed them to come, until the first were scarce two hundred feet away. Then, with a sudden shout, the Indian leaped to his feet and dashed fearlessly toward them. This unexpected move, as he had intended, stopped the foremost wolves in a huddled group for an instant, and in this opportune moment Wabi leveled his gun and fired. A long howl of pain testified to the effect of the shot. Hardly had it begun when Wabi fired again, this time with such deadly precision that one of the wolves, springing high into the air, tumbled back lifeless among the pack without so much as making a sound.
Running to the prostrate Roderick, Wabi drew him quickly upon his back, clutched his rifle in the grip of his arm, and started again for the tamaracks. Only once did he look back, and then he saw the wolves gathering in a snarling, fighting crowd about their slaughtered comrades. Not until he had reached the shelter of the tamaracks did the Indian youth lay down his burden, and then in his own exhaustion he fell prone upon the snow, his black eyes fixed cautiously upon the feasting pack. A few minutes later he discerned dark spots appearing here and there upon the whiteness of the snow, and at these signs of the termination of the feast he climbed up into the low branches of a spruce and drew Roderick after him. Not until then did the wounded boy show visible signs of life. Slowly he recovered from the faintness which had overpowered him, and after a little, with some assistance from Wabi, was able to place himself safely on a higher limb.
"That's the second time, Wabi," he said, reaching a hand down affectionately to the other's shoulder. "Once from drowning, once from the wolves. I've got a lot to even up with you!"
"Not after what happened to-day!"
The Indian's dusky face was raised until the two were looking into each other's eyes, with a gaze of love, and trust. Only a moment thus, and instinctively their glance turned toward the lake. The wolf-pack was in plain view. It was the biggest pack that Wabi, in all his life in the wilderness, had ever seen, and he mentally figured that there were at least half a hundred animals in it. Like ravenous dogs after having a few scraps of meat flung among them, the wolves were running about, nosing here and there, as if hoping to find a morsel that might have escaped discovery. Then one of them stopped on the trail and, throwing himself half on his haunches, with his head turned to the sky like a baying hound, started the hunt-cry.
"There's two packs. I thought it was too big for one," exclaimed the Indian. "See! Part of them are taking up the trail and the others are lagging behind gnawing the bones of the dead wolf. Now if we only had our ammunition and the other gun those murderers got away from us, we'd make a fortune. What—"
Wabi stopped with a suddenness that spoke volumes, and the supporting arm that he had thrown around Rod's waist tightened until it caused the wounded youth to flinch. Both boys stared in rigid silence. The wolves were crowding around a spot in the snow half-way between the tamarack refuge and the scene of the recent feast. The starved animals betrayed unusual excitement. They had struck the pool of blood and red trail made by the dying moose!
"What is it, Wabi?" whispered Rod.
The Indian did not answer. His black eyes gleamed with a new fire, his lips were parted in anxious anticipation, and he seemed hardly to breathe in his tense interest. The wounded boy repeated his question, and as if in reply the pack swerved to the west and in a black silent mass swept in a direction that would bring them into the tamaracks a hundred yards from the young hunters.
"A new trail!" breathed Wabi. "A new trail, and a hot one! Listen! They make no sound. It is always that way when they are close to a kill!"
As they looked the last of the wolves disappeared in the forest. For a few moments there was silence, then a chorus of howls came from deep in the woods behind them.
"Now is our chance," cried the Indian. "They've broken again, and their game—"
He had partly slipped from his limb, withdrawing his supporting arm from Rod's waist, and was about
