Elfie nodded, and offered her ideas on the subject to the approval of his authority. The young man listened, offered suggestions here and there, and then, with a sudden backward thought, he remembered a trinket in his possession--a little pearl bracelet, a trifle, but beyond anything appropriate to the costume in hand. Within himself he resolved to send home immediately for it, and to present it to Elfrida on the night of the dance. In the days that followed it seemed to him that he saw strangely little of her, and the little that he did see was less than satisfactory. Her absence from the piazza, and her refusals to go paddling with him, she excused on the plea of being busy with her new costume. But even on the pier at the bathing hour she seemed to shun him, or noticed him only with jeers and gibes at what she called his laziness. “Ah, can anybody have a soul that is afraid of the sea?” she cried. “Come, Mr. Martin, let us race over to the monument!” With a splash and a flounce the two set out together, the green bathing dress and the triumphant blue; while Glyn sat alone on the wharf with a leaden heart and rage at his soul. This state of affairs had very little altered when at last the day of the dance arrived. A hundred times in the interim had Stephen resolved to give up the whole affair and go home; but then he decided to wait and see this new Undine in the flesh. To his anxiety, the bracelet had not yet arrived; nor did it come until the last post on the evening of the dance, after everybody had gone upstairs to dress. In joyful relief, Stephen slipped the little box in the pocket of his improvised admiral’s costume, and ran downstairs to the hall to wait for the coming of his Undine. Elfrida did not appear till late, when the room was filled with whirling harlequins and Pompadours and Swiss peasant maidens. The admiral stood by the door, waiting for her, his little box in his hand and his heart in his mouth. Finally, as though she had been on the watch to avoid him, he saw her enter the hall by one of the long windows opening from the veranda without. In spite of his vexation, he could not but smile with sheer pleasure at the sight of her, as her eyes and her white teeth flashed a smile upon the room. In her pale, sea-green draperies, dragging heavily at the hem with a fragile border of urchin shells, her creamy neck and shoulders bare, her flowing yellow hair bound and wreathed with strands of dark, wet seaweed--oh, she was pretty, indeed! Stephen sprang forward. “Good-evening, Undine! Here--I have something for you, will you let me give it to you? A little ornament to complete your costume.” “You may give it to me later,” she replied, with an indifference that chilled and baffled him; and he watched her miserably as she swung off into the two-step with a tall, sunburned youth from Boston--a conceited-looking pup, Glyn told himself, in a vain attempt at consolation.
