used Tom could not as yet tell. It was
evidently not the one nearest the planing mill, for Tom could not
hear the buzzing sound. It was well he had put his attachment on
several instruments.
"One moment, please," said Mrs. Damon, to the unknown at the other
end of the wire. This was in accordance with the pre-arranged
plan.
"Well, what is it?" asked the man, impatiently. "I have no time to
waste."
Tom heard again the same gruff tones, and he tried in vain to
recognize them.
"I want you take down a message to Mr. Damon," said his wife.
"This is very important. It can do you no harm to give him this
message; but I want you to get it exact. If you do not promise to
deliver it I shall call all negotiations off."
"Oh, all right I'll take the message; but be quick about it. Then
I'll give you the address where you are to send the papers."
"This is the message," went on Mrs. Damon. "Please write it down.
It is very important to me. Have you a pencil?"
"Yes, I have one. Wait until I get a bit of paper. It's so dark in
this booth--wait until I turn on the light."
Tom could not repress a pleased and joyful exclamation. It was
just what he had hoped the man would do--turn on the light in the
booth. Indeed, it was necessary for the success of the trap that
the light be switched on. Otherwise no picture could be
transmitted over the wire. And the plan of having the man write
down a message to Mr. Damon was arranged with that end in view.
The man would need a light to see to write, and Tom's apparatus
must be lighted in order to make it work. The plot was coming
along finely.
"There!" exclaimed the man at the other end of the wire. "I have a
light now. Go ahead with your message, Mrs. Damon. But make it
short. I can't stay here long."
Then Mrs. Damon began dictating the message she and Tom had agreed
upon. It was as long as they dared make it, for they wanted to
keep the man in the booth to the last second.
"Dear Husband," began Mrs. Damon. What the message was does not
matter. It has nothing to do with this story. Sufficient to say
that the moment the man began writing it down, as Tom could tell
over the sensitive wire, by the scratching of the pencil--at that
moment Tom, knowing the light was on in the distant telephone
booth, switched on the picture-taking apparatus. His receiving
apparatus at once indicated that the image was being made on the
sensitive plate.
It took only a few seconds of time, and
