In fig. 5° the gun is shown mounted on an intermediatecarriage elevated and depressed by the screw A. The telescopic. From Bethells Modem Guns and Gunnery.

To lay the gun, thelayer works the laying screw A till the telescope points at thetarget; the gun also, if no elevation has been given, is thenpointing straight at the target. To give the gun the elevationnecessary for the range, the elevating number on the right ofthe gun now works the elevating screw B till the gun is sufficientlyelevated, the amount given being shown in yards of range ona drum. The motion given to the gun does not disturb theintermediate carriage with the telescope attached to it, and thetelescope still remains layed on the target. Once the sights arelayed on the target, the elevation of the gun may be changedin a moment by a turn of the elevating wheel, without disturbingthe laying. The la
