���sary. In the photograph on the left, the inventor is shown with a piece of his own broad film in his hand, barely a foot long, and to the right a strip of standard film. It takes seventy-five feet of the standard film to equal the foot of broad film. The machine is intended for amateurs. It will be appreciated also by parents who wish to preserve picture records of their growing children.

Making Pictures and Projecting Them with the Same Machine

A MACHINE that will not only take motion pictures but will also project them is the invention of Kasimir de Pro- szynski. It is about the size of a folding typewriter. Its weight is four pounds.

Instead of using the ordinary standard film, on which the pictures are the size of a postage stamp, it has its own film, which is about the width of an envelope. On this negative the pictures are exposed, each one about the size of a baby's finger nail. From the negative a print is made and this in turn is placed in the machine and used to project the picture on the wall. The lens used in taking the pic- tures is used again in projecting them. This is done by the aid of a small lamp, the light for which may be secured from any socket.

Instead of taking the pictures lengthwise of the film, the pic- tures are exposed across, as in reading. The diminutive size

��Building a Park Around the

Debris of a Burned -Down


SOME time ago the beautiful, two- story, Polytechnic High School of Fullerton, Cal., was completely gutted by fire. When the city decided to erect a new high school on a larger scale than the one which had been destroyed it was found necessary to select a new building site. In consequence the old grounds were aban- doned and lay as a "white elephant" on the hands of the city until an enterprising member of the city board of trustees conceived the plan of converting the plot into a park at a minimum expenditure of money. The plan was adopted. The debris from the fire was cleared off the ground, with the exception of the stately arch of concrete and the front foundation of the old building. These told a story and were ornamental so they were incorporated into the new park.
