"Wait! Let me give you a hand, you idiot! Don't tip her like that."

But Enos Quibb bore his weight on the frail craft, and he was heavier—with all the water he had swallowed—than Horace. The latter could not balance the fragile craft, and, just as little Hicks let out his bellow, the canoe went over, and the black-browed youth was shot in a perfect parabola over the head of the sinking constable.

The latter went down again. It was plain that water was not his natural element. He remained under longer than Pence; but when he came to the surface for the second time, Pence seized him.

"Now we'll see some fun," prophesied Phillips as the Spoondrift slowly moved toward the spot. "Quibby has lost his head completely."

"And no great loss," muttered Midkiff. "Maybe he'd get some sense."

"Hush! Hush! This is a serious moment," breathed Kingdon, manipulating the tiller with care.

And it was a serious moment for the two struggling in the water. Quibb got a strangle hold almost immediately on Horace Pence, and they went under. Pence was a strong swimmer, but a person needs a chance to breathe if he is going to do anything in the water.

Their heads again showed above the surface, and the constable let out a gurgling yell. Horace was grimly silent. In that very exciting moment Kingdon felt a thrill of admiration for the leader of the other camping party.

"Hit him a clump on the head!" shouted Red Phillips, leaning over the catboat's rail as she approached the imperiled pair.

Horace, however, was in no position to do that. He had his right arm around the constable, holding his head above water; and, as the man continued to struggle, his rescuer needed his other hand, as well as his feet, to paddle with. Besides, to strike a really heavy blow while in the water is all but impossible.
