Jack was, however, conscious of the fact that the doctor was watching him in a side-long way, as if expecting to hear him make some objections. As, however, the boy was silent, the doctor spoke. "Rather an ugly jump, Jack," he said. "Think you can manage it?" "Oh, I think so. I shall try." "Try? It must not be a try. It has to be done." "Yes, I can do it," said the lad confidently. "Oh yes, you can do that, Mr Jack," said Ned in a whisper, as the doctor turned off to speak to Lenny; "think it's only a ditch a foot deep." The boy could not think that with the water roaring beneath him far below, and he could not help glancing back up the steep slope they had descended. This looked so forbidding and meant so much toilsome work, that he felt as if he would rather do the leap, though all the same there was the climb on the other side. Still there was an attraction there in the shape of the strange birds, which he was as eager to secure as the doctor. "Who'll go first?" said the doctor. "Here, I will." He handed his gun and satchel to Ned, walked a little way to select the broadest and clearest path, which happened to be a couple of feet higher than the opposite side, stepped back as far as he could, took a short run, and landed easily a couple of feet clear. "There: nothing," he cried, "but I shouldn't like to try it back. Throw my satchel over, Ned." This was done and deftly caught. Then the gun was carefully pitched across, the others followed, and the specimens shot that morning. Then one by one the sailors leaped over, and Jack and Ned remained. "Will you go next, Ned?" "Me, sir, and leave you behind? 'Tisn't likely. Don't think about it, sir. It's easy enough. Off you go. The thinking's worse than the doing." To an ordinary school-boy it would have been nothing. His legs, hardened by exercise, would have sent him across like a deer, but Jack's muscles only a short time before were flaccid and weak in the extreme. Still the voyage had done something; the strong will growing up within him did more, and without a moment's hesitation, feeling as if his reputation was at stake, he went sharply to the starting-point, took the short run, and leaped, but too hurriedly. If he had gone quietly to work it would have been different; as it was, he cleared the gulf and landed on the other side, but without throwing himself forward sufficiently to recover himself, and Ned uttered a cry of horror as he saw the lad apparently about to totter backward into the depths below. Lenny saved him by a curiously awkward-looking act. He had been on the look-out on one side, the doctor on the other, to give the lad a hand as he landed, but instead of a hand he gave him an arm, delivering a sharp blow on the back, and driving him into safety just as he was hopelessly losing his balance, and the men gave a cheer.
