“Is it crazy she is? Is that what you mane?” demanded O’Hara, not a little excited by the inference he drew from what his companion had said.

“You needn’t call it by any such name as that. I believe she is an invalid; and, after all she has been through during the last twenty-four hours, it wouldn’t be very strange if she were a little out of her head. I don’t like to lose sight of her. There she is, walking up and down the poop-deck as though she were running a race with her own shadow. Will you send one of the watch down to tell Mr. Frisbone how it is with her, or ask him to come on deck without saying what is wanted?”

“Troth, I’ll do so myself!” replied the captain, hurrying down through the engine-room.

He had hardly disappeared before Miss Rodwood started to run with all her might towards the stern of the steamer. Tom Speers leaped up the ladder to the hurricane-deck in season to see her spring over the low railing into the sea.

“Man overboard! man overboard! Stop her!” cried Tom at the top of his lungs; and they were not feeble lungs.

He cut loose the life-buoy which was lashed to the railing, and threw it overboard. But Tom was not content with this action: he kicked off his shoes, and stepped out of his heavy pea-jacket and coat at the same moment, and plunged into the sea.

CHAPTER VIII.
THE VILLE D’ANGERS.

“HELP, help! Save me!” cried Miss Rodwood in the water, at some distance from Tom Speers.

As the girl had voluntarily thrown herself into the sea, Tom could not understand why she called for assistance. He had struck the water only a few seconds after she sprang overboard, and she could not be at any great distance from him. He was a strong swimmer, and the sea was very smooth. He heard the cry of the girl repeated as he came up with the life-buoy he had thrown overboard. Placing it before him, he swam with all the speed he could make, and reached the sufferer when she was quite exhausted by her efforts. She could swim a little herself, and had more confidence in the water than most persons who had never tried to do so.

“Don’t be afraid!” cried Tom, when he saw in the gloom of the night that she was still struggling to keep afloat.
