Tom started work on his Wizard Camera, as he called it, the
next day--that is he began drawing the designs, and planning how
to construct it. Ned helped him, and Koku was on hand in case he
was needed, but there was little he could do, as yet. Tom made an
inspection of his shop the morning after the chicken thief scare,
but nothing seemed to have been disturbed.

A week passed, and Tom had all the plans drawn for the camera.
He had made several experiments with different forms of
electricity for operating the mechanism, and had decided on a
small, but very powerful, storage battery to move the film, and
take the pictures.

This storage battery, which would be inside the camera, would
operate it automatically. That is, the camera could be set up any
place, in the jungle, or on the desert, it could be left alone,
and would take pictures without any one being near it. Tom
planned to have it operate at a certain set time, and stop at a
certain time, and he could set the dials to make this time any
moment of the day or night. For there was to be a powerful light
in connection with the camera, in order that night views might be
taken. Besides being automatic the camera could be worked by
hand.

When it was not necessary to have the camera operate by the
storage battery, it could be connected to wires and worked by an
ordinary set of batteries, or by a dynamo. This was for use on
the airship, where there was a big electrical machine. I shall
tell you more about the camera as the story proceeds.
