"As watertight as a coffin," was Ben's estimate of their quarters. "We'll get out when he's a mind to let us out, and not before." He tried the door, just to substantiate his estimate of its solidity. It did not budge.

"Well, here we are," he declared philosophically, and sat down on the bed.

Dare followed his example. Their minds went back simultaneously to the moment of the accident.

"We found the Mary all right," said Ben grimly, "but I never thought we'd learn where she was like we did."

"I happened to look to the leeward," said Dare, "and I saw her on top of us, I gave a shout."

"Aye, I heard it just before the crash. I was wellnigh throwed overboard by the shock. But it so happened that when I flung out me hand I found the Mary's bob-stay, and hung on to it. Our boat sunk in two minutes."

"She must have been cut right in half," said Dare.

"Aye."

They both considered their marvellous escape for a few minutes, then relegated it to the back of their minds as a subject for future discussion. There were other things to be considered now.

"I don't think there's any suspicion as to who we are," whispered Dare close to Ben's ear.
