 "Just the same way with an opera. You watch the screen and see a picture of the stage, full size. Marie Jansen comes out and sings and the band will play charm ing waltZing minuet,' and then she dances around and the audience applauds. May be DeWolf Hopper comes in and cracks a joke or Digby Bell wakes up from his twenty-five years sleep and asks if the New Yorks have won game yet"
 "How do you expect to do all that, MT. Edison?"
 D. "If it is desired to reproduce an opera or play will get the company to give a dress rehearsal for me. place back of the orchestra on table a compound machine consisting of a photograph and 8 kineto- graph, with capacity of thirty minutes continuous work. The orchestra plays, the curtain rises and the opera begins. Both machines work simultaneously, one recording sound and the other taking photographs, recording motion at the rate of forty-six photographs per second. Af- terward the photographic strip is devel- oped and replaced in the machine, a pro- jecting lens is substituted for the photo graphic lens and the reproducing part of the photograph is adjusted. Then, by means of calcium light, the effect is re- produced lifesize on white curtain, repro ducing to the audience the original scene wi tn all it's sounds and all the motions of the actors exactly as in the original scene.
 The photograph which MT. Edison will use in his compound motion and sound re- producer will be an improvement on the photographs now in common use. He said yesterday that he had now in use about 500 photographs of which he was taking constant observations. The result of all these observations he will embody in the improved photograph to be used with the kinetograph.
 The kinetograph is nothing more nor less than photograph camera arranged in a new way to do new work. Its name implies its use. The name is derived from the Greek words meaning to move" and "to write," and the machine literally fur nishes complete record of all the motions made before it. It photographs action. As | Edison says: ''The kinetQRraph does for the eye, what the photograph does for the ear" In this small box camera MT. Edison places roll of gelatine film about three fourths of an inch wide and of any length desired. The interior of the camera is of course arranged on plan similar to that on which the ordinary roll cameras are made. The gelatine strip Is unrolled from one spindle and rerolled from another, and in passing from the first spindle to the second is carried before the lens of the camera. The shutters of the camera are arranged to be worked by the shaft at- tached to the cylinder of the photograph. This shaft also works the spindles which carry the rolls of film.
 The mechanism of this camera is so ar ranged that when the shutters open the spindles stop and the gelatine film is fixed before the lens. In less than the forty sixth part of second the photograph is taken, the shutters snap, the spindles turn and the gelatine slip moves on for 8 new photograph. The arrangement is so con- plete that forty-six perfect photographs are taken in one second.
 "The trouble with all attempts hereto fore made to reproduce action and motion by photographs" said Edison, twas that the photographs could not be taken in se- ries with sufficient rapidity to catch ac- curately the motion it was desired to re- produce. Hemment, the man who photo graphs running horses in the thousandth part of one second, had the idea, but he failed because he could take only half a dozen photographs at time. = All these photographs, if reproduced in a series would have shown a jerky and imperfect motion. My idea was to take a series oi instantaneous photographs of motions SC rapidly that in the reproduction the pho toGraphic representatives become resolved
