"It's pretty evident that the place is deserted," he decided, "unless Hans has locked Gretchen up inside while he clears out to see his pals. I wonder if there's a cuddy-hole in the other end of the boat, where the crew keep ropes and spare gear?"

Making his way for'ard, Peter discovered that there was a forepeak, but the cover was securely padlocked. No place of refuge there! He paused and surveyed the mound of coal glistening in the misty starlight. "I wonder--yes there was an old barrel on the bank; that will do."

Seized by an inspiration, Peter joined his brother.

"Swim for it!" he exclaimed; but, as the Carrs ran to the side of the barge, with the intention of taking a header into the canal, a voice was heard calling:
