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. 



The broad strip of film used 

 in the machine equals 

 the 75 feet of standard film 

 shown above. At right is

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 



of the pictures makes Only a The con crete arch of the entrance and foundations

Building a Park Around the 



Debris of a Burned -Down 



Schoolhouse 



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.
