He felt himself going, and yelled aloud.

Over he toppled, face foremost, splash! into the pool.
The boy saw him vanish, and heard the splashing of his struggle in the water.

The unfortunate man emerged again into the boy's field of vision, hatless and streaming with water, and screaming! Never before had the boy heard screams from a man.
This astonishing stranger appeared to be tearing at something on the side of his face.

There appeared streaks of blood there.

He flung out his arms as if in despair, leapt in the air like a frantic creature, ran violently ten or twelve yards, and then fell and rolled on the ground and over and out of sight of the boy.
