Meanwhile the situation of Jack Dudley became perilous to the last degree. To stop and fire insured his certain seizure by the grizzly, who would require but a moment to tear the life from him. Jack saw him so near, indeed, that he did that which no person would do except in the last extremity. He flung away his rifle, that it might not impede his flight, and concentrated all his energies into the one effort of running.
He had no time to look where he was going. He could only strive with the desperation of despair to preserve the distance between him and his pursuer, in the faint hope that something would intervene to save him. Fred was not only firing his gun as fast as he could, but he shouted to the bear, in the hope of diverting his attention from Jack, who could not keep up the unequal flight much longer.
The terrified fugitive leaped over boulders, dashed around interposing rocks, and bounded across open spaces, hardly daring to look over his shoulder, for he knew from the sounds of pursuit that the animal was at his heels. It seemed every moment as if the prodigious paw of the grizzly would smite him to the earth, when no human power could save him.
Suddenly the fugitive, while dashing forward in this blind, headlong fashion, found himself confronted by the canyon with which he and Fred had already had a memorable experience. It yawned at right angles to the course he was following, its width so great that it was impossible for him to leap it at that point. But he knew there must be some such place, and he continued his flight along the side of the chasm, hunting for a spot that would permit him to reach the other bank.
He did not stop to think how this could benefit him, for it was to be supposed that if the grizzly could outrun he could also outleap him, and the moment the fugitive landed on the further bank the brute would do the same, without losing an inch of the advantage already gained. In fact, Jack Dudley had no time to think of anything except to run with all the vigor which nature had given him.
All at once he saw a spot where the feat looked possible. There was no time for him to turn off to gain the momentum, but, measuring the interval with his eye, he gathered his muscles and leaped outward. The jump was diagonal, and made under most difficult circumstances.
Who shall describe the awful thrill that shot through Jack Dudley when, at the moment of leaving the rocky edge of the rocky wall, he was sure he was about to fail in his last effort? The other margin of the canyon wall appeared to recede, and he uttered a despairing cry, certain that the next instant he would go spinning down the frightful abyss.
It is at such critical times that the question of life and death is often decided by incidents so trifling that they are unnoticed. Had Jack Dudley retained his Winchester in his grasp he would have been lost. It would not have been alone the weight of the weapon, but its interference with the free use of his hands. As it was, the latter were untrammeled, and, though his feet missed a firm hold, he instinctively clutched the craggy projections, and, with a supreme effort, drew himself over the margin and beyond all danger of falling back into the canyon.
And where, all this time, was old Ephraim?
The remark just made concerning the effect of trifles was shown as strikingly in his case as in that of the fugitive. Despite his enormous weight and awkwardness of action, the grizzly without special exertion could have made the leap that had just been exhibited before his eyes had he been in his usual condition, but it has been shown that he had been struck by several bullets. Though most of these inflicted little more than flesh wounds, which under the circumstances were trifling, yet others did effective work. This was especially the case with those that found a lodgment in his head, which, big and tough as it was, lacked the power of turning aside a rifle-ball, as the indurated back of an alligator often does.
