They were, however, so far removed from the average drawing-room medley of twaddle and rattle that the music interpreted the words into its own universal language, and made them almost superfluous.

For the most part they were sad and passionate, and once or twice, especially when Radna Michaelis was singing, Arnold saw tears well up into the eyes of the women, and the brows of the men contract and their hands clench with sudden passion at the recollection of some terrible scene or story that was recalled by the song.

At last, close on midnight, the President rose from his seat and asked Natasha to sing the "Hymn of Freedom." She acknowledged the request with an inclination of her head, and then as Radna sat down to the piano, and she took her place beside it, all the rest rose to their feet like worshippers in a church.

The prelude was rather longer than usual, and as Radna played it Arnold heard running through it, as it were, echoes of all the patriotic songs of Europe from "Scots Wha Hae" and "The Shan van Voght" to the forbidden Polish National Hymn and the Swiss Republican song, which is known in England as "God Save the Queen." The prelude ended with a few bars of the "Marseillaise," and then Natasha began.

It was a marvellous performance.

Suddenly Natasha's voice soared up, as it were, out of the music, and a moment later the Song of the Revolution rolled forth in a flood of triumphant melody, above which Natasha's pure contralto thrilled sweet and strong, till to Arnold's intoxicated senses it seemed like the voice of some angel singing from the sky in the ears of men, and it was not until the hymn had been ended for some moments that he was recalled to earth by the President saying to him—

"Some day, perhaps, you will be floating in the clouds, and you will hear that hymn rising from the throats of millions gathered together from the ends of the earth, and when you hear that you will know that our work is done, and that there is peace on earth at last."

"I hope so," replied the engineer quietly, "and, what is more, I believe that some day I shall hear it."

"I believe so too," suddenly interrupted Radna, turning round on her seat at the piano, "but there will be many a battle-song sung to the accompaniment of battle-music before that happens. I wish"—
