One drag at that thin cord should have been sufficient to secure help, but it was forgotten, even though he touched it with his hands as they went to his helmet, and to make matters worse, he was kneeling now out of sight of those on deck; and for the moment all seemed over. He was blind, for a thick darkness had, as it were, come over him, mentally and bodily, in the intense horror of the moment, but through that darkness flashed scene after scene of the past, and he saw Hester, looking young and beautiful, gazing pityingly down at him, but without stretching out a hand to save, while, with a smile of triumph upon his countenance, there stood Laure, the bane of his existence.
