50Having the lantern, either a Triple or Biunial, in working order, thediscs all centred, and the crosses or carriers exactly trued, and in the exactcentre of condenser, by the method previously explained, commenceto register the first slide of any fresh series of effects to the trued carrieror cross slide, i.e., either by planing or building up the frames, so thatthe mats cover exactly the plain disc of the carrier or cross, and afterregistering slide no. i, register all succeeding slides to this.EFFECTS.Some Coniplicaied Effects., and how they should be jvorked.Exeter Theatre Fire.— (i) Exterior of Theatre by night, and lampsilluminated.

To work this effectively a triple is required, as three lanternsare in use at one time.Firstly, No. i exterior, then No. 2 and 3 are put on together, the rackslide No. 3 on which smoke i& painted, has a slip glass blacked, andwhen in its normal position all but obliterates the smoke itself.As 2 and 3 are dissolved on, gently turn the smoke rack, beingcareful that the handle is being turned the right way. To see the smokedescending instead of rising, at once makes an otherwise grand effectludicrous. To guard against such a mistake, cut deeply an arrow on theedge of the frame, so that in the dark the direction of the arrow may befelt.
