But Sonia, knowledge dawning in her face, clapped her hand over his mouth—and he read her conjecture in her eyes, and drew a great breath. The old man came again and laughed and cried and wrung his hand, and poured out his joy and wonder into the amazed ears of the conscience-stricken young musician. The floodgates of speech were loosened.

"You see what you have done, figlio mio. You see the miracle. This—this poor rubbish is of me, Angelo Fardetti. On it I spent my life, my blood, my tears, and it is a thing of nothing, nothing. It is wind and noise; but by the miracle of God I breathed it into your spirit and it grew—and it grew into all that I dreamed—all that I dreamed and could not express. It is my Song of Life sung as I could have sung it if I had been a great genius like you. And you have taken my song from my soul, from my heart, and all the sublime harmonies that could get no farther than this dull head you have put down in immortal music."

He went on exalted, and Sonia and Geoffrey stood pale and silent. To undeceive him was impossible.

"You see it is a miracle?" he asked.

"Yes," replied Geoffrey in a low voice.

"You never saw this before. Ha! ha!" he laughed delightedly. "Not a human soul has seen it or heard it. I kept it locked up there, in my little strong-box. And it was there all the time I was teaching you. And you never suspected."

"No, maestro, I did not," said the young man truthfully.

"Now, when did you begin to think of it? How did it come to you—my Song of Life? Did it sing in your brain while you were here and my brain was guiding yours, and then gather form and shape all through the long years?"

"Yes," said Geoffrey. "That was how it came about."

Angelo took Sonia's plump cheeks between his hands and smiled. "Now you understand, my little Sonia, why I was so foolish yesterday. It was emotion, such emotion as a man has never felt before in the world. And now you know why I could not speak this morning. I thought of the letter you showed me. He confessed that old Angelo Fardetti had inspired him, but he did not know how. I know. The little spark flew from the soul of Angelo Fardetti into his soul, and it became a Divine Fire. And my Song of Life is true. The symphony was born in me—it died in me—it is re-born so gloriously in him. The seed is imperishable. It is eternal."
