This ammunition-carriage was adopted for the Bengal horse artillery and galloper-guns, and is represented in the sketch (Plate No. 6). We must here again remark how nearly the present principle was approached, the gun and ammunition limbers similar, and the ammunition divided into several boxes; but still the fault already noticed in the gun-carriage, the unnecessarily long projection to which the limbering-hook was attached, was continued. This fault probably caused this pattern, both gun and ammunition-carriage, to be discarded, and it was not until twenty years had passed that the simple alterations necessary were introduced. The light field-carriages then at this period (end of 1801), were the beam-trail gun and ammunition-carriage with limber for the gallopers, and the double-cheek carriage and ammunition-tumbril for the foot artillery. As the elevating-screw is an important item in a carriage, a few lines to trace its progress will not be amiss. The earliest screw was fixed horizontally, and ran through a quoin, which, by its action, was forced in or out, depressing or elevating the gun; it was a cumbrous machine, and could scarcely have worked smoothly. This must have fallen into disuse between 1780 and 1790. At this latter date, a capstan-headed screw fixed in the centre transom had superseded it. A good deal of attention was given to the elevating-screw about this period, and many plans appear to have been proposed, among other officers, by Lieutenants Toppin and Taylor, as we learn from a minute by Colonel Deare; but what they were, it is not easy to say. The action of the screw was found to injure the centre transoms, and it was therefore placed a little in advance, the trunnions of the plate in which the screw worked resting on gudgeons fixed in each cheek; this gave the screw a power of self-adjustment to the movement of the gun, and most probably contemporary with this was the introduction of screws fixed to the neck of the cascable of the gun. Another pattern, and which probably followed, was one placing the screw under an elevating-board on which the gun rested.[35] In the sketch (Plate No. 6) the general character of the screws is shewn. A cursory notice must now be taken of the ordnance in use with the regiment. In the early times, 6–pounders were chiefly used; they were afterwards mixed with 3–pounders with the native corps, and 6–pounders with the artillery companies; the former most probably of 3¾, and the latter of 4¾ cwt. A heavier 6–pounder (6½ cwt.) superseded this light gun, and was in general use to the end of the century. This gun Major Woodburne’s committee proposed replacing again by a lighter one.
