him. "Trying to hypnotize yourself, Tom?"
"Not exactly. Quiet, Ned, please. I'm trying to listen."
Ned was too familiar with his chum's work to take offense at this. The young banker took a seat on a box, and silently watched Tom. The inventor shifted several switches, pressed one button after another, and tilted the polished metal plate at different angles. Then he closed the door of the little telephone booth, and Ned, through the ground glass door, saw a light shining.
"I wonder what new game Tom is up to?" Ned mused.
Presently the door opened, and Tom stuck out his head.
"Ned, come here," he invited. "Look at that metal plate and see if you can notice anything on it. I've been staring at it so steadily that my eyes are full of sticks. See what you can make out."
"What is this?" asked Ned. "No trick; is it? I won't be blown up, or get my eyes full of pepper; will I?"
"Nonsense! Of course not. I'm trying to make a photo telephone. I have the telephone part down pat, but I can't see anything of the photo image. See if you can."
