"Too late for tea now," said Helga, and once again Oscar went round and round with her. It seemed to him that Helga's face flashed with electric flame as she swirled out of the darkness into the red glow from the fire, and back again into the darkness.

One of the skaters started the Elf-song, others joined him, and then it was a scene of complete enchantment. The frost had laid its hand on the falls that fed the lake, and they were quiet; it had stroked the streams, and they were still; but if the voices of the waters were silent, the voices of the skaters rippled and rang in the crisp night air.

"Dance by night and dance by day,

Life and Time will pass away:

Love alone will last alway."

Oscar was enraptured. The humming of the skates, the swaying of the ice, the music of the singers, the heat, the glow, the sinuous movement, and above all the girl by his side, so bright, so beautiful, so full of life and laughter, carried away every sense, and flesh and blood were afire.

Then the moon rose, a brilliant moon, and it was reflected full and round and white in the black mirror of the ice, with its streamers going off from it, as if it had been a comet that had fallen to the earth, and lay there at their feet.

"Look! Let us cut across it," cried Helga, and away they shot in the darkness, with the moon's reflection receding as they followed it, until they came to the limit of the lake, and then the skaters and the fire and the singing were far behind them.

"What a will o' the wisp she is! I could catch you quicker than I could catch her!" said Oscar.

"You couldn't!"

"I could!"

"Do it then!" cried Helga, and off she went, laughing at first, but afterward silent yet breathing fast, and at last panting audibly while she twisted and turned to escape from him, until he came down on her at length with outstretched arms and a cry of "Done!" And then, before he knew what he was doing, he was clasping her to his breast, and she was clinging to him lest she should fall, and he was beating kiss after kiss upon her lips.
