Mark the edge of therack with an arrow so as to indicate which way the handle should turn,after a few seconds the hand is taken from the front and the flamesallowed to spread by pulling out the slip glass ; dissolve to the nextwhich is a similar scene, only the sea calm without an eccentric movementof the waves and tossing of the ship ; if the fire effect was put on to themoveable ship, it would be absurd to see the vessel rolling and theflames stationary : dissolve on this stationary view of vessel and gentlyextend the flames by pulling off the blacked slip glass of rack ; whenout to its full extent the flames cover the vessel ; introduce the picturewhich is exactly similar to the preceeding one, with the difference thatthe masts and bulwarks are burnt away, and that a slip glass isattached on which is painted a raft ; if these are truly registered andeffectively dissolved, the eff"ect can be given of the masts gradually beingconsumed. When the previous scene is dissolved completely off, the slipglass with raft is withdrawn from under the stern of the vessel ; nowreduce the amount of fire on vessel by pushing home the slip on rackfire slide, at the same time bringing on the last slide of the Ruins, asthe slip rack is pushed home the effect is given of the fire burning itselfout until nothing is left but a small flicker of flame, move the openfingers in front of the nozzle carrying fire, two or three times, then coverup completely, which leaves the burnt-out skeleton of the vessel showing,whilst this is on ; make clear two lanterns for the two remaining slideswhich are put on together,—this is imperative,—and they should beregistered in such a manner that no dark or light band shows on thehorizon, which will occur if the sea and sky do not register perfectly,the sea being painted on one slide, and the sky and wreck on anothera very realistic illusion of the sinking vessel is produced ; after sinkingthe wreck, be careful not to let the lever slip down.Sunrise on the Matterhorn.—The first slide is placed in thelantern, and in the slot of the front lens of same is placed a dark, blueglass, when the picture is on the screen it has the appearance of dawn,with just an outline of the mountain. The effect of the rising sun isbrought about by moving the slip glass off,—the second slide, afterthis has been uncovered about a third of its distance, gently withdrawthe coloured glass in front of the lens at the same time as illuminatingthe remaining portion of the mountain, which gives the illusion of the
