56 Motion Picture PROJECTION. Projecting Machines. The projection of these picture strips is accomplished in a lantern fitted with a special attachment for feeding the pellicular band through the light; which is usually that of an electric arc lamp, as it will be remembered that the picture is scarcely one-fourth as large as an ordinary lantern slide and therefore only about one-sixteenth the area; in other wwds, to secure the same brilliancy on the canvas it is necessary to use a light many times more intense than for an ordinary slide. Sometimes stereopticon projecting lanterns are fitted with moving-picture machine attachments so arranged that lantern slides and motion pictures can be projected alternately. The best practice, however, provides for separate machines, and for lecture work, dissolving stereopticons located above the motion-picture machine and farther over away from the operator. This gives easy and convenient access to all three mechanisms. A double-deck stand or support for the machines, and also for the metal boxes containing the necessary switches, cut-outs, etc., is desirable for a traveling outfit. This stand is then easily arranged on the backs
