Suddenly a shout came from Phil Levins, who had lagged in the rear. It was so full of terror, that Sam and Tom looked at each other in wonder and alarm.
"What's up now?" gasped the latter.
Phil was waving his arms wildly.
"Hurry up—hurry up!" he yelled, frantically, and the Ramblers broke into a run.
