Fred Greenwood made ready for the first jump. As in the former instance, the distance was so slight that it was not necessary to toss any of their impedimenta in advance of their own passage. It was easy to jump with the Winchester in one hand and the goodly piece of meat in the other. Since Fred had beaten his friend some time before, Jack quietly resolved to turn the tables by doing his best, and he was confident of far surpassing him, especially as Fred had no suspicion of his intention. "Go ahead," said Jack; "night isn't far off, and it will be dark by the time we reach camp." Fred took only a couple of paces for a start, when he bounded across the chasm with the ease of a chamois. Jack had sauntered a rod back, as if with no special purpose in mind, when his object was to secure the impetus that would land him far in advance of his comrade. Standing thus, he complacently watched Fred, as his body rose in air, gracefully curved over, and landed at a safe distance beyond the edge of the canyon. It was while Jack Dudley was standing thus that he fancied he saw a disturbance in the bushes where Fred was about to alight. It was so slight that he did not think it meant anything; and, without noticing it further, he started on a series of quick, short steps, which were to give him the necessary momentum to win the victory over his friend. At that instant Fred landed and emitted a cry of terror and warning. "Look out, Jack! Don't jump! Stop! stop!" But, though Jack heard the cry, it was too late to heed it. He was so near the edge of the canyon that had he checked himself he would have gone spinning to death down the abyss. The leap must be made, and, gathering his muscles, he rose in the air, with his legs gathered under him, and with the certainty that the jump would far surpass the one that he had just witnessed. In that critical moment, when his body rose and seemed suspended over the gorge, Jack's attention was fixed upon the strange actions of Fred. The instant he landed he darted to one side, and with his rifle struck at something in the bushes which Jack could not see. As he did so he recoiled, and was in the act of advancing and striking again, when Jack landed upon the ground beyond. As he did so he heard a vicious, locust-like whir, whose meaning he recognized. An immense rattlesnake was in the bushes, and Fred had descended almost upon it. But for the tremendous effort of Jack he would have dropped squarely upon the velvety body, with consequences too frightful to be thought of; but his great leap carried him over it, while the attack of Fred upon the reptile, in the effort to save his companion, diverted the attention of the rattlesnake for an instant.
