"No, indeed. I'm going to let it take what ever pictures happen
to come along to be taken after we get through making some
special early ones. You see my camera will be a sort of watch
dog, only of course it won't catch any one--that is, only their
images will be caught on the film.

"Oh, I see," exclaimed Ned, and then he helped Tom fix the
machine for the test.




CHAPTER VII - WHAT THE CAMERA CAUGHT


"Well, is she working, Tom?" asked our hero's chum, a little
later, when they had set the camera up on a box in the garden. It
pointed toward the main shop door, and from the machine came a
clicking sound. The electric light was glowing.

"Yes, it's all ready," replied Tom. "Now just act as if it
wasn't there. You walk toward the shop. Do anything you please.
Pretend you are coming in to see me on business. Act as if it was
daytime. I'll stand here and receive you. Later, I'll get dad out
here, Koku and Eradicate. I wish Mr. Period was here to see the
test, but perhaps it's just as well for me to make sure it works
before be sees it."

"All right, Tom, here I come."
