For there was an ominous sharp crack, a cry from Bob, and he held up the stump of his broken paddle. It had failed him at the critical moment!
Poor Sandy collapsed when he saw this sight. He dropped his now useless gun in the bottom of the canoe, and cowered there, shutting out the terrible sight of the island slipping past by covering his eyes with his hands.
It had been so nearly accomplished that the catastrophe seemed all the more keen, and he could not bear to look at the receding haven which they had hoped to make their refuge.
Of course now the canoe would be wholly in the power of the victorious current, which must carry it onward like a chip, until shortly the incoming water would attain such a level as to sink the craft. Then—but Sandy could not allow himself to picture what would happen when he and his brother were forced to battle with the cruel giants contained in those leaping waves.
But what was this? Surely there was a jerking motion to the craft that had been missing after Bob's ill-fated paddle broke!
Sandy wonderingly uncovered his eyes. He stared in dismay. Why, where was Bob? The place where he had set while working like a hero was deserted! Had he seen the folly of further resistance, and thrown himself over the side, welcoming the fate that seemed so certain?
Sandy half started up, cold with fear. The boat was still heading toward that end of the island, so close that he could easily have tossed a biscuit on the nearest bushes, half under water now!
Some unseen influence was evidently urging the canoe along its course, just as though a friendly giant, concealed from view under the rushing, tumultuous waters, had decided at the last instant to give the adventurous boys a parting chance.
Then all at once the truth flashed over him. Why, to be sure, it was Bob! He had refused to be utterly cast down by the sudden reverse that snatched away his valuable paddle by snapping it in half. He had instantly plunged over the side of the boat. He was in the water, gripping the hesitating canoe, and striving with all his power to urge it into peaceful waters!
