These qualities are exhibited to a high degree in the illustration of the railway in Holborn, for while we are glad that an electric train is to run under Holborn, no living or dead man has ever seen a train in Holborn itself. Such fakes occupy a considerable time in manufacture.

While the explanation is simple, the carrying out of this fake was a matter of some difficulty.

First a picture of a railway junction was taken. Then it was necessary to take a photograph of Holborn. This in itself is a simple enough matter, but in this case it was necessary to obtain a picture of exactly the same scale, in order that the railway lines might be fitted to appear as a natural part of the picture.

This was only managed after several ineffectual shots. Then the latter negative was placed in the printing frame with the roadway masked. When sufficiently printed the railway negative was placed in the frame on the same paper. That part of Holborn already printed was masked, and thus the rails were printed in the space where the roadway should have been. The result will make Londoners rub their eyes.

The two ghost photographs are specially calculated to puzzle not a few who are unacquainted with the tricks of the art. Like most puzzling things, they are simplicity itself when explained. There is not a suspicion of mystery about them. By the same method any amateur may manufacture a whole gallery of family ghosts for his delectation.

The invocation of our ghosts was on this wise.

A nice, quiet, suitable sort of churchyard not a dozen miles from London was chosen, and, with a couple of assistants, I hied myself to it one bright and anything but ethereal morning.

First, the lady was posed till we were satisfied that she looked scared enough for a ghost to be turned on. A second later my other assistant, with the best dining-room tablecloth thrown over his head, came on the scene, glided with healthy earthly steps to a pre-arranged spot, and took up his position.

Snap went the pneumatic shutter. The photographic plate, one of an extremely rapid variety, was exposed for the space of a second, and the ghost hid himself behind the camera and took off his tablecloth. The lady meanwhile remained in the same position, and directly the ghost disappeared, snap went the shutter again on her. So in the interval of nine seconds this wonder was perpetrated.
