But Ruth said never a word. The emergency appealed to her quite as seriously as it did to her friends. But she knew that if Mary Cox was to be saved they must act at once.
She flung off her cap and light outside coat. She wore only canvas shoes, and easily kicked them off and ran, in her stocking-feet, toward the paddle-box. Onto this she climbed by the short ladder and sprang out upon its top just as The Fox came up after her plunge.
By great good fortune the imperiled girl had been carried beyond the paddles. But the Lanawaxa was steaming swiftly past the girl in the water. Ruth knew very well that Mary Cox could not swim. She was one of the few girls at Briarwood who had been unable to learn that accomplishment, under the school instructor, in the gymnasium pool. Whereas Ruth herself had taken to the art "like a duck to water."
Mary's face appeared but for a moment above the surface. Ruth saw it, pale and despairing; then a wave washed over it and the girl disappeared for a second time.
