d upon the table.

"All that is very interesting," commented Weissmann, "but
inconclusive. Is it all over?"

"Oh no," answered Mrs. Lambert. "They are uniting upon something
wonderful--I feel it."

As they listened the horn moved feebly, uneasily rising a few inches,
only to fall as though some weak hand were struggling with it; but at
last it turned towards Weissmann, and from it issued the voice of a
little girl, thrillingly sweet and so clear that Serviss could hear
every word. She addressed Weissmann in German, calling him father,
asking him to tell mother not to grieve, that they would soon all be
together in a bright land.

To this Weissmann replied in harsh accent: "You assert you are my
daughter?"

The voice sweetly answered: "Yes, I am Mina--"

"But Mina could not understand a word of English--how is that?"

The little voice hesitated. "It is hard to explain," she replied,
still in German. "I can _understand_ you in any language--but I can

Thereupon he addressed her in French, to which she replied easily, but

As this curious dialogue went on Serviss was searching vainly for an
explanation. "Mr. Clarke, will you kindly speak at the same time that
this voice appears?"

Clarke began a discourse, and the two voices went on at the same time.
The young scientist then said: "Mrs. Lambert, will you permit Kate to

three voices precisely together; but at last it seemed that the
child's voice was produced at the same time that Clarke spoke and
while Kate's hand covered the mother's mouth.

Thereupon the little voice said farewell, and all was silent for a few
moments. The cone rose again into the air and a soft, sibilant voice
addressed Mrs. Lambert.

"Oh!" she cried, joyfully. "It is Robert!--Yes, dear, I'm listening.
I'm so glad you've come. Can't you talk with Professor Serviss?--He
says he will try," she said to the company.

As Morton waited the cone gently touched him on the shoulder, and a
moment later a man's voice, utterly different from the first one and
of most refined accent, half spoke, half whispered: "We are glad to
meet you, professor. I am deeply gratified by your interest in our
dear girl."

"Who are you?" he asked, moved, in spite of himself, by a li
