There is onlyone way to attaina harmonious re-lation betweenscreen drama andincidental two must beDfdinated. Stanley W. Lawlon, general nuisicaldirector of a chain of New York mo\-ingpicture and vaude\ille theaters, hasinvented and constructed an electricalorchestra director which accomplishesthis harmonious relation. The pictureprojecting machine in the booth ab-soluteh controls the electrical orchestradirector in the pit. The theor\ of theLawton photopla\ orchestral director, asit is called, is simple. By electricitx,signals are aulomalicalh- flashed to theorchestra from the projection machineon the screen as the picture ^• few seconds a different signal. automaticalh- co- flashes, informing the nnisicians thatsentimental, liveK, or tragic music isto be played. The musicians score andcues have been arranged beforehandduring rehearsal. They merely readtheir part and follow the cues, changingfrom selection to selection as thesignals machine inthe center of theorchestra consistsof a flat, oblongbox with red glasssides, which sur-mounts a curiouslooking cylinder ordrum. As thefilms are reeledthrough the pro-jector, signals flashfrom the red glassbox. For example,if the herosmother is indeaths embrace,the lettersTREM, mean-ing tremolo, areflashed, and theorchestra respondsaccordingly. So accurate is the electrical cue- a recent rather Inflections marked on the paper recordare duplicated on the side of the cylinderby steel pegs that contact a magnet ing system that atamusing but exacting test given thea|)paratus, tlie signal DRUM wasflashed and obe>ed at the very instantwhen a comedian on the screen
