The Preventer, or Inner Breeching, will be found indispensable to avoid accident when running out to leeward in a sea-way. For with a trained crew, and all precaution in handling the levers and In-Tackles, there is a liability to the gun getting away, in which case it moves out with great violence, and may do serious damage. On one such occasion an XI-in. gun cracked the stout iron straps of the Compressors, and seemed but just prevented from freeing itself entirely and going overboard over the Port-sill. Not being able to replace the Straps, the Compressors were useless till late in the cruise. Preventer Breechings were then fitted, and answered so well that the practice was continued at sea as usual. They now form part of the equipment of all XI-in. guns, and should be just taut when the gun is out, and the Trucks of the Carriage reach but do not ascend the curve of the forward Hurter.

[17] This is to detach from the bottom of the Chamber the fragments of burnt Flannel that are apt to adhere and solidify.

[ [18] This practice encumbers the deck, and interferes materially at times with the management of the gun. Trial was therefore made on board the Plymouth, where the gun was on a covered deck, of hooks attached to the beams above, near each piece, in which the Sponges and Rammers were placed after having been used. The only objection was, that too much time might be lost in so doing; but after continued trials this was found not to be the case, when the men had been properly trained.

[ [19] Stopping the Vent is omitted by many practised artillerists, as unnecessary in extinguishing fragments of the cartridges. But as so much importance has been and still is attached to its performance, and it costs so little trouble, it seems better to continue the practice, particularly when so many accidents occur from premature explosion, not only to untaught and careless people, in saluting on holidays, but also on shipboard, where they ought not to happen.

[ [20] Sometimes the box has been fitted too tightly to the Shell, or has contracted on it, and delay is caused in loading. This should be attended to in season.

[ [21] Otherwise the stout stuff and seams found necessary with heavy charges might resist the primer, and cause a failure to explode the powder.

[ [22] It was the habit at the Experimental Battery, and in the experimental cruise of the Plymouth, to mark the handle of the Rammer, so that there should be no doubt as to the charge being home. This is always useful, but particularly so in case of the gun bursting, as it makes sure of an important fact.

[ [23] It is a common practice in loading, to expend much zeal in striking the cartridge one or two blows to insure its being home, which is quite unnecessary when the mark on the handle affords so much better evidence thereof.

[ [24] The XI-in. Shell weighs, when loaded, 135 lbs.; the lifting and entering it into the muzzle was one of the objections of those who were opposed to the use of heavy calibres. There was not one of the crew of the Plymouths XI-in. gun who was not found able, on trial, to take up the Shell and unassisted to put it in the Bore, when the ship was still. At sea a very simple implement was used—an iron segment with a bent handle on opposite sides. The Shellmen, 7, 8, turned the shell out of the box into this ladle, placed on the deck near No. 3, the Loader, who, when ready, took the left handle, and No. 5 (the 2d Loader) the right. These two lifted the Shell towards the muzzle, and No. 4 (Sponger), standing on the Slide, received the right hand from No. 5 as soon as within reach. No. 3, stepping on the Slide, and No. 4 continued to raise the Shell to the muzzle, which was not difficult, because of the Bore being conveniently high above the Slide on which they were standing; the Sabot projecting beyond the Ladle was entered into the muzzle, and the Shell pushed in, No. 5 taking the ladle back and laying it on the deck.

[ [25] As this is very firmly fixed in the recess of the metal stock, it is to be removed by pulling directly on the tail, which, if twisted, will be likely to break, and thus cause a loss of time. The patch is passed to the Gun Captain, who puts it in his belt-box, and is afterwards handed to the Quarter deck by the Lieut. of Division, in order to verify the number of shells fired. When the Fuze has been uncovered, care must be taken not to let it be touched by the moisture of the hand, or by the sea-water.
