The gravel, mixed with mud, formed a good footing; and Bruce and Bart stopped here for a time, and put their boots on, so that if they had to swim they might not be impeded with bundles.

The water was running swiftly by. It seemed wider now than it did at the top of the bank. But they did not hesitate. In they went side by side, Bruce on the right, and Bart below him on the left. The water grew deeper and deeper. It came up to their waists, then up to their armpits. Bart could not possibly stem it a moment longer. He was lifted from his feet, and borne on.

Those waiting at the top of the bank felt their hearts stop beating as they looked.

But Bart’s head was above water, and he struck out bravely for the opposite shore. He knew he would not have far to swim, for he had already gone nearly half way when he was swept off his feet. The current still bore him down, but his own efforts were dragging him to the opposite shore at every stroke.

After Bart had lost his footing, Bruce still walked on. He held himself so that he could resist the current to some extent. But at last he, too, lost his footing, and was swept after Bart. He struck out strongly; and while carried down by the current, he, too, drew nearer the opposite shore.

Bart had just touched bottom, and sprang up, with the water scarce higher than his waist, and looked around for Bruce. As he looked, he caught sight of Bruce’s face. It was turned toward him in agony, close by him, and but a little behind. Two hands were flung out, and with a gasp and a groan Bruce sank.

For an instant Bart stood petrified with horror. A wild thought of sharks flashed through his mind. But the next instant he had grasped Bruce, and was dragging him half fainting, still gasping, out of the water. In a few minutes they were on the bank, where they both sat down.

“It was a—a palpitation—of the—the heart,” gasped Bruce. “I’ve felt—queer.—ever since that—affair—on the—the cliff.”

“Yes. You’ll have to keep quiet, Bruce, for some months to come. You see you’ve been exerting yourself tremendously to-day, and this last thing has been too much. You’ve got to look out, for a thing like this is not to be trifled with.”

By this time the other boys had rushed down, and were on the opposite side halloing, and asking what was the matter.
