The boy that could come across a cave without being filled with a burning curiosity to take a peep in and, if possible, explore its interior, would have to be a very dull fellow, and Frank certainly was not of that kind. This dark aperture was no doubt the mouth of a cave of some sort, and he determined to inspect it. When he got within about fifteen yards, he noticed what he had not seen before, that there was a well-defined track leading from the cave to the underbrush to the right, which had evidently been made by some large animal; and with somewhat of a start Frank immediately thought of a bear.

Now, of course, under the circumstances, there was but one thing for him to do if he wished to illustrate his common sense, and that was to hurry back to the tent as fast as possible for reinforcements. Ordinarily, he would have done so at once, but this time he was still smarting a bit at his poor marksmanship in the case of the "lucifee," and the sight of the track in the snow suggested the idea of winning a reputation for himself by killing a bear without any assistance from the others. It was a rash and foolish notion; but then boys will be boys.

Moving forward cautiously, he approached within ten yards of the cave and then halted again, bringing his rifle forward so as to be ready to fire at a moment's notice. Bending down until his eyes were on a level with the opening, he tried hard to peer into its depths; but the darkness was too deep to pierce, and he could not make out anything. Then he bethought him of another expedient. Picking up a lump of snow, he pressed it into a ball and threw it into the cave, at the same time shouting out, "Hallo there! Anybody inside?" A proceeding that capped the climax of his rashness and produced quite as sensational a result as he could possibly have desired, for the next moment a deep angry roar issued from the rocky retreat and a fiery pair of eyes gleamed out from its shadows. The critical moment had come, and taking aim a little below the shining orbs, so as to make sure of hitting, Frank pulled the trigger. The report of the rifle and the roar of the bear followed close upon one another, awaking the echoes of the adjoining heights. Then came a moment's silence, broken the next instant by a cry of alarm from Frank; for the bear, instead of writhing in the agonies of death, was charging down upon him with open mouth! Once more he had missed his mark and only wounded when he should have killed.

There was but one thing for him to do—to flee for his life; and uttering a shout of "Help! help!" with all the strength of his lungs, he threw down his rifle and started for the tent at the top of his speed.

It was well for him that the snow still lay deep upon the ground, and that he was so expert in the use of his snow-shoes; for while the bear wallowed heavily in the drifts, he flew lightly over them, so that for a time the furious creature lost ground rather than gained upon him. For a hundred yards the boy and bear raced through the forest, Frank continuing his cries for help while he ran. Looking back for an instant, he saw that the bear bad not yet drawn any nearer, and, terrified as he was, the thought flashed into his mind that if the brute followed him all the way to the camp he would soon be despatched by the men, and then he, Frank, would be entitled to some credit for thus bringing him to execution.

On sped the two in their race for life, the boy skimming swiftly over the soft snow, the bear ploughing his way madly through it, until more than half the distance to the camp had been accomplished. If Johnston had heard the report of the rifle and Frank's wild cries for help, he should be coming into sight now, and with intense anxiety Frank looked ahead in hopes of seeing him emerge from the trees which clustered thickly in that direction. But there was no sign of him yet; and shouting again as loudly as he could, the boy pressed strenuously forward. There was greater need for exertion than ever, for he had reached a spot where the snow was not very deep and had been firmly packed by the wind, so that the bear's broad feet sank but little in it, and his rate of speed ominously increased. So close was the fierce creature coming that Frank could hear his paws pattering on the snow and his deep panting breath.

Oh why did not Johnston appear? Surely he must have heard Frank's cries. Ah, there he was, just bursting through the trees into the opening, with Laberge and Booth close at his heels. Frank's heart bounded with joy, and he was tempted to take a glance back to see how close the bear had got. It was not a wise thing to do, and he came near paying dearly for doing it; for at the same instant his snowshoes caught in each other, and before he could recover himself he fell headlong in the snow with the bear right upon him.

CHAPTER XI.

THE GREAT SPRING DRIVE.

At the sight of Frank's fall the three men gave a simultaneous shout of alarm that caused the bear to halt for a moment in his fierce pursuit, and lifting his head to look angrily in the direction from which the sound had come. This action saved the helpless boy—striving to regain his feet only a yard from death. The instant the creature's broad breast was exposed, Johnston threw his rifle to his shoulder, and without waiting to take aim, but ejaculating a fervent "Help me, O God!" pulled the trigger. The report of the rifle rang out sharp and clear, the heavy bullet sped through the air straight to its mark, and with it embedded in his heart the mighty animal, leaving untouched the boy at his feet, made a mad bound across his body to reach the assailant who had given him his death wound.
