"If I were to organize a committee of men like Weissmann and Tolman, and other men of international fame, willing to test your daughter's powers, will you give over this public demonstration--this publishing of a challenge?"
Clarke interrupted almost angrily. "Not unless you promise to--"
"Be silent!" commanded Weissmann.
From the horn came a faint murmur, so dim, so far, Serviss could, with difficulty, distinguish the words. "We will consider that. I am going. Guard my girl. Good-bye."
The horn, again seemed to rest, and for a long time no sound or stir broke the silence, till at last Viola began to writhe in her chair in greater agony than before.
"I think she is waking," said Morton.
Mrs. Lambert answered, quickly: "No. Some great event is preparing--when this paroxysm passes some very beautiful test will come."
While Morton and Weissmann were considering this the girl again became silent as a stone, and a moment later a clear, sweet sound pulsed through the air as if an exquisite crystal bell had been struck. Then, while still this signal trembled in his ear, a whispering noise developed just before the young man's face, as if tremulous lips were closing and unclosing in anxious effort to communicate a message without the use of the trumpet.
"Is some one trying to speak to me?" he asked, gently.
Three measured strokes upon, the tiny bell replied, and with their pulsations the room seemed to stir with a new and different throng of winged memories. The very air took on mystery and beauty and a sweet gravity. Matter was for the moment as subtle, as imponderable as soul.
"Who is it?" he asked, and into his voice, in spite of himself, crept a note of awe.
The answer came instantly, faint as the fall of an autumn leaf on the grass.
"Mother."
Kate bent eagerly forward, "Who was it, Morton?"
Ignoring her question Morton addressed the invisible one. "Can't you speak again?"
There was no reply and the whispering ceased. Almost instantly the horn seemed grasped by a firm and masterful hand, and the rollicking voice of a man broke startlingly from the darkness in words so clear, so resonant, that all could hear them.
"Hello, folks. Is this a Quaker meeting?"
"Who are you?" asked Morton.
"Can't you guess?"
Kate gasped. "Why, it's Uncle Ben Roberts!"
The voice chuckled. "Right the first time. It's old 'Loggy'--true bill. How are you all?"
Kate could hardly speak, so great was her fear and joy. "Morton Serviss, what do you think now? Ask him--"
The voice from the trumpet interposed. "Don't ask me a word about conditions over here--it's no use. I can't tell you a thing."
