"Well, when all's said and done," said Caius to himself, rolling upon a sleepless bed, "it's a very extraordinary thing."

Next morning he hired a boat, the nearest that was to be had; he got it a mile and a half further up the shore. It was a clumsy thing, but he rowed it past the mouth of the creek where he used to fish, all along the water front of Day's farm, past the little point that was the beginning of the rocky part of the shore, and then he drew the boat up upon the little island. He hid it perfectly among the grass and weeds. Over all the limited surface, among the pine shrubs and flowering weeds, he searched to see if hiding-place for the nymph could be found. Two colts were pastured on the isle. He found no cave or hut. When he had finished his search, he sat and waited and watched till the sun set over the sea; but to-day there was no smiling face rearing itself from the blue water, no little hand beckoning him away.

"What a fool I was not to go where she beckoned!" mused Caius. "Where? Anywhere into the heart of the ocean, out of this dull, sordid life into the land of dreams."

For it must all have been a dream—a sweet, fantastic dream, imposed upon his senses by some influence, outward or inward; but it seemed to him that at the hour when he seemed to see the maid it might have been given him to enter the world of dreams, and go on in some existence which was a truer reality than the one in which he now was. In a deliberate way he thought that perhaps, if the truth were known, he, Dr. Caius Simpson, was going a little mad; but as he sat by the softly lapping sea he did not regret this madness: what he did regret was that he must go home and—talk to Mabel.

He rowed his boat back with feelings of blank disappointment. He could not give another day to idleness upon the shore. It was impossible that such an important person as himself could spend long afternoons and evenings thus without everyone's knowledge. He had a feeling, too, born, as many calculations are, of pure surmise, that he would have seen the mermaid again that afternoon, when he had made such elaborate arrangements to meet her, if Fate had destined them to meet again at all. No; he must give her up. He must forget the hallucination that had worked so madly on his brain.

Nevertheless, he did not deny himself the pleasure of walking very frequently to the spot, and this often, in the early hours before breakfast, a time which he could dispose of as he would without comment. As he walked the beach in the beauty of the early day, he realized that some new region of life had been opened to him, that he was feeling his way into new mysteries of beatified thought and feeling.

A week passed; he was again upon the shore opposite the island at the sunrise hour. He sat on the rock which seemed like a home to his restless spirit, so associated it was with the first thoughts of those new visions of beauty which were becoming dear to him.

He heard a soft splashing sound in the water, and, looking about him, suddenly saw the sea-child's face lifted out of the water not more than four or five yards from him. All around her was a golden cloud of sand; it seemed to have been stirred up by her startled movement on seeing him. For a moment she was still, resting thus close, and he could see distinctly that around her white shoulders there was a coil of what seemed like glistening rounded scales. He could not decide whether the brightness in her eye was that of laughing ease or of startled excitement. Then she turned and darted away from him, and having put about forty feet between them, she turned and looked back with easy defiance.

His eyes, fascinated by what was to him an awful thing, were trying to penetrate the sparkling water and see the outlines of the form whose clumsy skin seemed to hang in horrid folds, stretching its monstrous bulk under the waves. His vision was broken by the sparkling splash which the maiden deliberately made with her hands, as if divining his curiosity and defying it. He felt the more sure that his senses did not play him false because the arrangement of the human and fishy substance of the apparition did not tally with any preconceived ideas he had of mermaids.

Caius felt no loathing of the horrid form that seemed to be part of her. He knew, as he had never known before, how much of coarseness there was in himself. His hands and feet, as he looked down at them, seemed clumsy, his ideas clumsy and gross to correspond. He knew enough to know that he might, by the practice of exercises, have made his muscles and brain the expression of his will, instead of the inert mass of flesh that they now seemed to him to be. He might—yes, he might, if he had his years to live over again, have made himself noble and strong; as it was, he was mutely conscious of being a thing to be justly derided by the laughing eyes that looked up at him from the water, a man to be justly shunned and avoided by the being of the white arms and dimpled face.
