The mermaid smiled again. The feminine half of her was pleased with the compliment to her good looks.

"I'm afraid you're a sad flatterer," she said, coquettishly. She lowered her blue eyes, then uplifted the lashes and looked full into his face in a manner that made his heart bound. One little finger was shaken playfully at him. Edwin seized the hand. It was warm; human blood pulsated through it! And as he held it his companion gave just a bit of a squeeze. A score of girls had done the same in bygone sentimental hours. But none so deftly.

"This is certainly an odd adventure," he remarked. "Tell me, lady of the lake, do you often sit here in this unconventional fashion with gentlemen callers?"

"What would you give to know?" she asked, teasingly.

"You are the first for a long, long time," she went on. "Last summer there was a man in a gray uniform who saw me, but he looked so uninteresting I swam away."

"When are you here?" he asked, earnestly.

"I love to sit on the bank when fair Aurora makes the dawning day grow rosy," she acknowledged, "but I have to flee to the depths when the full sun comes." She looked to the east. "It is growing late," she added, hurriedly; "I must be going."

"Not yet, not yet," he pleaded.

"Do not detain me," she cried; "I must go. It means life to me."

Gracefully she glided into the water at his feet.
