In another moment he had scaled the fence and was clambering awkwardly down the rocks. And as he came close he found her a very pretty damsel indeed, with youthful, rosy cheeks, fetching blue eyes and long, light tresses that hung unconfined from her head down upon the sloping rocks behind her. She was smiling, and yet he thought he detected a renewed disposition to slip away from him before he had drawn too close. Then he had a shock. She was only half a woman! The other half of her was fish--scaly fish--partly submerged in the waters of the lake! He paused irresolutely. It was all right, you know, to read about mermaids in old mythologies and fairy tales. But to encounter one in this year of Our Lord, so near home as Druid lake! Oh, fudge! the boys at the Ariel Club would never get through "joshing" him should he ever say he had seen such a thing. It could not be true; it was too amazing! He was a fool to let his nerves get the better of him. He had better cut out those visits to the river resorts, or next he would be seeing pink elephants climbing trees. First thing he knew he would wake up in that stuffy room at home. No, he couldn't be dreaming! There was the railing, and the lake, and the white tower, and General Booth's home, and the Madison-avenue entrance, and the Wallace statue and a dozen other familiar spots in a most familiar perspective. And there, too, was the damsel in flesh and blood, or, rather, flesh and fish! She was the first to speak. "Good morning to you, stranger." She spoke English--good, clear mother-tongue. Her lips were parted in that alluring smile, and her manner was as saucy as that of any fair flirt he had ever known of womankind. "In the name of Heaven, who are you?" he stammered as he sat down, awkwardly, beside her. She laughed outright--mischievously, mockingly. "I? I am the nymph of the lake. Long years ago I was the naiad of the woodland spring that is now deep down yonder," indicating a spot out in the lake. "But they dammed me in and turned great floods of water in here, and mighty Jupiter gave me my new title." "And are you really half fish?" She laughed again. "I am what you see." As she spoke she gracefully swayed the lower half of her in the water. A million glistening scales prismatically reflected the increasing morning light. She was half fish, all right. There was no doubt about that. "By gosh! here's a rum go!" muttered Edwin to himself. "What did you say?" queried the mermaid. "I said, if you must know, 'By Jove! you are a beauty,'" he replied, gallantly and impetuously. The mermaid smiled again. The feminine half of her was pleased with the compliment to her good looks.
