he might after the warning of his wife's death three nights
before. "Won't you answer one other question?"

Fainter, almost imperceptibly, came a rap! rap!

For several minutes the old man sat absorbed in thought,
trance-like. Then, gradually, he seemed to realise that we were
in the room with him. With difficulty he took up the thread of
the conversation where the rappings had broken it.

"We were talking about the photographs," he said slowly. "I hope
soon to get one of my wife as she is now that she is
transfigured. John has promised me one soon."

He was gathering up his treasures preparatory to putting them
back in their places of safekeeping. The moment he was out of the
room Craig darted into the cabinet and replaced his mechanism in
the box. Then he began softly to tap the walls. At last he found
the side that gave a noise similar to that which we had heard,
and he seemed pleased to have found it, for he hastily sketched
on an old envelope a plan of that part of the house, noting on it
the location of the side of the cabinet.

Kennedy almost dragged me back to our apartment, he was in such a
hurry to examine the apparatus at his leisure. He turned on all
the lights, took the thing out of its case, and stripped off the
two sheets of ruled paper wound around the two revolving drums.
He laid them flat on the table and studied them for some minutes
with evidently growing satisfaction.
