[Illustration: "She Beheld A Sight Which Sent Through Her A Pang Of Horror.">[

Hilda had only one thought, and that was this, that the sea had given up its dead, and that her victim had come to confront her now; in the hour of vengeance to stand between her and another victim. It was but for an instant that she stood, yet in that instant a thousand thoughts swept through her mind. But for an instant; and then, with a loud, piercing shriek, she leaped back, and with a thrill of mortal terror plunged into the thick wood and fled afar--fled with the feeling that the avenger was following fast after her.

The shriek roused Lord Chetwynde. He rushed back. Zillah had fainted, and was lying senseless on the grass. He raised her in his arms, and held her pressed convulsively to his heart, looking with unutterable longing upon her pale face, and pressing his burning lips to her cold brow. There was a great terror in his heart, for he could not think what it might be that had happened, and he feared that some sudden alarm had done this. Bitterly he reproached himself for so agitating her. He had excited her with his despair; and she, in her agitation, had become an easy prey to any sudden fear. Something had happened, he could not tell what, but he feared that he had been to some extent the cause, by the agitation which he had excited within her. All these thoughts and fears were in his mind as he held her upraised in his arms, and looked wildly around for some means of restoring her. A fountain was playing not far away, under the trees, and the babble of running water came to his ears amidst the deep stillness. There he carried his precious burden, and dashed water in her face, and chafed her hands, and murmured all the time a thousand words of love and tenderness. To him, in his intense anxiety, the moments seemed hours, and the passage of every moment threw him into despair. But at last she revived, and finally opened her eyes to see the face of Lord Chetwynde bending over her.

"Thank God!" he murmured, as her opening eyes met his.

"Do not leave me!" moaned Zillah. "It may come again, and if it does I shall die!"

"Leave you!" said Lord Chetwynde; and then he said nothing more, but pressed her hand in silence.

After a few moments she arose, and leaning heavily on his arm she walked with him up the path toward the fountain. On the way, with many starts and shudders of sudden fear, she told him what had happened. She had heard a noise among the trees, and had hurried out, when suddenly a figure rushed up to her--an awful figure! It wore a black robe, and over its head was a cowl with two holes for the eyes. This figure waved its arms wildly, and finally gave a long, wild yell, which pierced to her heart. She fell senseless. Never while life lasts, she said, would she be able to forget that abhorrent cry.

Lord Chetwynde listened eagerly. "That dress," he said, "is the costume of a Florentine society that devotes itself to the burial of the dead. Some one has worn it here. I'm afraid we have been watched. It looks like it."

"Watched! who could think of such a thing?"

"I don't know," said Lord Chetwynde, thoughtfully. "It may have been accidental. Some masker has watched us, and has tried to frighten you. That is all. If I thought that we could have any enemy, I would say that it was his work. But that is impossible. We are unknown here. At any rate, you must not think that there has been any thing supernatural about it. It seems to me," he concluded, "that we have been mistaken for some others."
