The ship swung round and round and settled down.

There was a flash of lightning, and by it Castell saw Betty holding the unconscious Margaret in her strong arms.

She saw him also, and screamed to him to come to the boat.

He started to obey, then remembered Peter.

Peter might not be dead; what should he say to Margaret if he left him there to drown?
He crept to where he lay upon the deck, and called to a sailor who rushed by to help him.
