This almost always happens in a new machine, and then there are uninteresting work and depressing waiting.
As soon as I see that my invention will act as I want it to act, I shall have you in the lens-house with me.

We may not be able to do very much at first, but when I really begin to do anything I want both of us to see it done." There was no flooring in that part of the lens-house where the machine was set up, for Clewe wished his new light to operate directly upon the earth.

At about eight feet above the ground was the opening through which the Artesian ray would pass perpendicularly downward whenever the lever should be moved which would connect the main electric current.
When all was ready, Clewe sent every one, even Bryce, the master-workman, from the room.

If his invention should totally fail, he wanted no one but himself to witness that failure; but if it should succeed, or even give promise of doing so, he would be glad to have the eyes of his trusted associates witness that success.

When the doors were shut and locked, Clewe moved a lever, and a disk of light three feet in diameter immediately appeared upon the ground.
