“What’s that?” screamed Wallace.
“A whistle—a signal!” came from Frank. “It’s a signal to us! Answer it! Now—together!”
They shouted as loudly as they could. It seemed that the wind tore the cry from their lips and carried it away into the night. Again they shouted.
Toot! toot! toot!
Nearer yet sounded the whistle, but they were so close upon that dreadful ledge!
Up to the top of a swell they rode, and then they shouted with joy, for, close at hand, a gleaming light danced over the surging sea. They knew succor was near. Could it reach them in time?
They continued their cries, and the relentless waves seemed trying harder than ever to sweep them upon the ledge.
All at once the light seemed to gleam close over them, and they saw the prow of a boat. They also saw the face of Jack Diamond close behind a lighted lantern that he was holding aloft.
“Here we are!” shouted Frank. “Don’t run us down!”
“Make ready!” came back the call. “Jump as we swing alongside.”
