"Isn't he humming!"

Suddenly Whittington thrust out his left arm.

"He's going to turn down May Street!" shouted Lane. "Bound to the station after his father. He'll hit Sanders, sure as fate! Hi! Hi there, Percy!"

Heedless of the warning, Whittington whirled round into May Street and plunged full tilt into the hotel bus, striking it a glancing blow back of its front wheel. There was a tremendous crash.

"Come on, fellows!" cried Lane.

They ran at top speed toward the wreck. Through the clearing dust three figures were visible, extricating themselves from the ruins. Sanders, the hotel chauffeur, was groaning and rubbing his ankle. His only passenger, a bald, thick-set man, with smooth face and bulldog jaw, had a bleeding scratch down his right cheek and a badly torn coat. Whittington, apparently unharmed, was chalky and stuttering from fright.

Spurling, for all his slowness, was the first to reach the wreck. He helped the stout stranger to his feet, and the man turned angrily toward Whittington. An exclamation of surprise burst from both.

"Dad!"

"Percy!"

Understanding struggled with indignation on the older man's face.
