When Captain Alvin Strong went to rejoin his ship, he parted from his sweetheart, Alice, with a promise to marry her at the termination of the voyage. He left a locket in her possession as a souvenir. The ship, however, was wrecked with all on board save Captain Strong, who was washed ashore on a distant part of the coast in an unconscious condition. When he was restored to animation by the kindly fishermen of the village, he had forgotten who he was. In other words, the calamity of the shipwreck had deprived him of his memory. After he regained his physical health, he remained in the fishing village and secured a job amongst the fishermen. Meanwhile, his sweetheart, at home, had not given up hope of his return and daily frequented the shore in expectation of seeing his ship return. As Alvin Strong progressed in his new work, he also progressed in the affections of the daughter of his benefactor, the old fisherman. In course of time he married the girl, and a baby was born to him. Still, he had no recollection of the past beyond the day when he was thrown upon the shore and was restored to life. Everything in his mind before this was a blank. One day, in company with several of bis fellow fishermen, he had to take a trip by water to the village which he had left two years before as Captain Strong. Agnes recognized him. So did her mother and many of the villagers. But he failed to recognize them. There was a scene of anguish between the gird and him, and she at last brought about his recognition of her by showing him the locket that he had given her two years ago. Instantly reason returned to him and he realized the position that he stood in. He had pledged himself to this girl, but he had married another and there was a child. Duty triumphed, however, and he returned to his wife and child, leaving Agnes in despair and disappointment.
