"Hullo, what's that?" came in the voice of Tom Grandon. "Who threw something overboard?"
"Sounded like somebody jumping into the water," replied Captain Ponsberry, who was on deck with the first mate.
An examination was made, but in the fog and darkness nothing could be discovered.
"It was mighty queer," was Grandon's comment. "Somebody must have done it."
"Where are Shamhaven and Peterson?"
"In the forecastle, I suppose. Do you think——"
"I don't know what to think. See if they are there."
At once Tom Grandon ran off, and made a tour not only of the forecastle but also of the forward deck. He called the men's names several times, and others quickly joined in the hunt.
"They are gone!" he ejaculated, running back to where Captain Ponsberry stood.
"Gone? Then it must have been them jumping overboard that we heard!"
