CH. XI] MOVING PICTURE EXHIBITION 435 



again and the ends pinned together in the lower film magazine. 

 Splice permanently later. 



When the end of the film is reached, turn up the house lights and 

 put out the arc light, or push the lamp over to the lantern-slide side 

 as the case may require. Turn the crank a few times until the film 

 has all rolled into the lower film magazine. 



The lower reel is taken out and put on the rewinder, the empty 

 reel from the upper magazine put in its place and a new roll of film 

 is put in the upper magazine.

At the end of the exhibition all of the films are rewound and put 

 in the box to be kept until the next day or to be sent away. 



598. Home projectors and advertising magic lanterns. In 



addition to the regular moving picture machines there have been 

 two side-line developments. One of these is a relatively cheap 

 moving picture machine with a small arc lamp for the house light- 

 ing system ( 127) or some other form of radiant (Ch. IV, V). 

 Some of these small instruments like the "Phantoscope" of Jenkins, 

 take the standard size of motion picture film. Edison has put out 

 another form, the "Home Kinetoscope," (fig. 236). This does not 

 project the ordinary size of moving picture, but very small pic- 

 tures. Instead of one row of pictures on the film there are three 

 rows. With the small pictures in three rows, a film 80 feet (24.38 

 meters) long contains as many pictures as 1000 feet (304.8 meters) 

 of the ordinary moving picture film, and the mechanism is so. 

 arranged that the three rows are shown without a break.
