They did not stop to notice the size of the stream, but plunged at once into its current.
Henry sank with a mighty splash, and went down, down, it seemed to him, a mile.

Then his feet touched a hard, rocky bottom, and he shot back to the surface, spluttering and blowing the water out of eyes, mouth and nostrils.

A brown head was bobbing beside him.

He seized it by the hair, pulled it up, and disclosed the features of Paul, his comrade.

Paul, too, began to splutter and at the same time to try to swim.
Splash! A heavy body struck the water beside them with a thud too great for that of a man.
