Her skill in the water was to him a constant wonder, a constant delight. His own attempts at diving and swimming he soon gave up, finding this northern water too cold for him; and so, in spite of Elfrida’s gibes, he sat on the dock and watched her as she took backward somersaults and dead-man dives and went down below in search of sinking clam shells. Her high jump from the piles, holding up her little skirt with a dainty hand, and winking blithely as she descended, was a thing long to be remembered for sheer mirth, for frank, childish joy. Yet it was then that Stephen sighed as he regarded her. After all, was it a woman he loved, with a warm human heart to respond to his own; or a careless mermaid, a cold creature, whose sole joy was thus dancing, plunging, flashing through the foam of the white, curling waves?

So far as he could judge, there was no real affection in her heart except this for her friend, the sea. Toward her mother, a heavy, placid woman with literary pretensions, Elfrida was kind in an impersonal, far-off sort of way; to the other girls in the hotel—who respected her for her high dives and hated her for her monopoly of the few men at Pemaquid—she seemed indifferent, with a kind of mocking politeness; while toward her little court of admirers she showed a capricious tyranny, at times almost savage. To these things even the adoring eyes of Stephen Glyn could not be blind; and one day when, owing to a severe headache of her mother’s, she was obliged to forego her swim, and appeared at dinner a muttering thundercloud, it was impossible for even the most ardent of adorers to pass by these signs without a sigh.

True, she had shown a tender heart toward the lifeless cod and hake; and sometimes, as she looked at the sea, in the uproar of a summer squall or in the silvery silence of a fog, Glyn would be startled by the look that suddenly crept into her eyes.

“Ah!” she breathed one evening, as they sat together watching the sunset from the pier. “Ah, it wouldn’t be hard to die, would it, if one could lie at the bottom of the sea?” Glyn grunted uncomfortably in answer, and tried to look as though he agreed with this sentiment.

The next day, when they were out canoeing together, Elfrida surprised him by reverting suddenly to one of the first conversations of their acquaintance. “You said you were going to tell me about Undine,” she said, “but you haven’t—not a word.”

Glyn sighed as he regarded her. She had been unusually tantalizing, not to say aggravating, that afternoon, and his honest heart was sore within him. But what better mood, what better occasion, for relating the story of the unfortunate water nymph, from the time she first appeared in the hut of the old fisherman, a light-hearted, soulless child, to the unhappy hour when, abandoned by the man she loved, she vanished silently into her native element—“a woman gifted with a soul, filled with love and heir to suffering.”

It was but recently that Stephen had read the story, and he told it well, for, though a lawyer, he was in love, and he had a poetical soul. Elfrida listened in silence, her face turned away, her hand trailing in the still water beside her. After the story-teller had finished, there was a pause.

“Well,” said Stephen, disappointed, “didn’t you like it?”

Elfrida glanced up at him—a quick, irresolute glance, quite unlike her usual frank gaze. She seemed about to speak, but to Glyn’s disappointment she turned away her head again, so that her face was hidden from him. With her trailing hand she drew a long, dripping spray of brown seaweed from the water.

“What did Undine gain, after all,” she said, “by leaving the sea?”
