Once, twice, thrice he saw the imperative beck of the little hand; then it rested again upon the rippled surface, and the sea-maid waited, as though secure of his obedience.
The man's startled ideas began to right themselves.

Was it possible that any woman could be bathing from the island, and have the audacity to ask him to share her sport?
He tarried so long that the nymph, or whatever it might be, came nearer.
Some twelve feet or so of the water she swiftly glided through, as it seemed, without twist or turn of her body or effort; then paused; then came forward again, until she had rounded the island at its nearest point, and half-way between it and his shore she stopped, and looked at him steadily with a face that seemed to Caius singularly womanly and sweet.

Again she lifted a white hand and beckoned him to come across the space of water that remained.
Caius stood doubtful upon his rock.

After a minute he set his feet more firmly upon it, and crossed his arms to indicate that he had no intention of swimming the narrow sea in answer to the beckoning hand.
Yet his whole mind was thrown into confusion with the strangeness of it.
He thought he heard a woman's laughter come across to him with the lapping waves, and his face flushed with the indignity this offered.
The mermaid left her distance, and by a series of short darts came nearer still, till she stopped again about the width of a broad highroad from the discomforted man.

He knew now that it must be truly a mermaid, for no creature but a fish could thus glide along the surface of the water, and certainly the sleek, damp little head that lay so comfortably on the ripple was the head of a laughing child or playful girl.
