The others listened. Faintly from the direction of the sea came a sound—unmistakable.
“A boat!” cried Jack. “I’ll not take off my coat yet.”
“A motor boat, too,” added Ed.
“And coming this way,” went on Walter.
“Come on, fellows, give ’em a hail!” suggested Dray.
Up to now, with all their shouting and blowing of the whistle, they had neither seen nor heard of a craft. They had drifted too far out. If any had come within hearing distance the occupants had paid no heed to the calls for help. Now there was one approaching, that was evident.
“All together, now!” called Jack, and they united their voices in a shout.
“There are her lights!” called Dray.
“Yes, and she’s heading right over here,” agreed Ed.
A little later the red and green lights came nearer.
