"Oh, mercy!" cried the girls, in one voice.

"The river is deep enough here!" exclaimed Louise. "Give him an oar to climb on."

A sudden scream from the boy in the water brought the melancholy news that he could not swim! His boat drifted off as quickly as it was freed from his weight, and the girls were not quite near enough to reach him.

"Hurry, hurry!" begged Louise, who was now rowing. "He may sink, then what would he do?"

But the boy was splashing around making a brave attempt to keep up, and really doing so by the flat handed action with which he patted the water.

All embarrassment was now forgotten, as the scouts pulled up carefully to where the boy was just bobbing up and down, each movement adding to his peril.

"Climb in!" commanded Louise as they reached him. But he could scarcely put his hand to the oar, and the girls noticed his face was blue white.

"Oh, dear me!" cried Julia, "he is fainting or something," and nervous though she was, it was she who managed to get the first grip on the weakened boy.

It was no easy matter to get him into the boat; he was struggling and gasping for breath, and could make very little effort to help himself. Finally, when all four girls had succeeded in keeping the boat balanced and dragging him into it, he gave one painful gasp, closed his eyes, and sank into unconsciousness.
