with the calibre and weight of the gun for which the cartridges are intended. Tanks for musket-powder must be marked MUSKET-POWDER; and this powder may be put up in either of the kind of charges allowed which will make the best stowage, the bags properly stencilled.
Tanks containing saluting powder are to be marked "SALUTING." It is to be kept in bags, stencilled "saluting."
40. No loose powder is ever to be taken or carried on board ship, and all, whether public or private belonging to officers, must be safely stowed in the magazines.
41. All metallic cartridges for small arms, percussion caps, and percussion or friction primers, or other articles containing fulminating matter, must be kept in boxes prepared for the purpose, and the boxes must be stowed separately from other articles, in a dry, secure, and safe place, under lock and key, and are on no account to be put in the magazine. It is recommended that they be distributed in two or three places, a portion conveniently at hand.
42. The fireworks, after carefully removing all fulminating matter, such as caps or primers, if any such be used to ignite them, are to be stowed in their proper packing-boxes in other light boxes of suitable length, made water-tight, with lock and key, and to fit between the beams and carlines of the gun decks of frigates and berth decks of single-decked vessels. Those for instant use must be placed near the after hatch, and the remainder abaft that position, if possible, so as to be constantly under the care of the sentinel at the cabin doors. In no case, however, are they to be placed over any standing light or lantern on any deck.
43. All ammunition packing-boxes, shell-bags, and metal cases are to be preserved, and returned into store at the end of the cruise.
44. No coopering is ever to be done in the magazines of ships. Should powder be received on board in barrels, the hoops and heads must be started on the orlop or berth deck before entering the magazine.
45. In stowing shell-rooms, filled shells are to be stowed together in boxes or bags; those having fuzes of different times of burning, and each kind of fuze, will be placed in tiers or ranges distinctly separate. (See Article ON FUZES, C. IV.) Empty shells are to be stowed by themselves, unsabotted, in bulk, in a dry place.
46. Whenever guns are to be struck below, or prepared for transportation, the gunner will see that the bores are washed with fresh water, carefully sponged, thoroughly dried, and coated with melted tallow, and a wad dipped in the same material inserted, and connected with a tompion by a lanyard. He is to see that the tompion is put in securely, and the vent and all screw-holes stopped by a plug of soft wood, and puttied over.
47. He is to examine and report daily, before 10 A.M. and 8 P.M., whether the guns and all their equipments; the whips for supplying shot and shells; the arm-chests, armory, and small arms; the supply and reserve division boxes, and other articles furnished as ordnance and ordnance stores, are in good order and in place, and make immediate report to the Commanding or Executive Officer of any defects or deficiencies which he may discover at any other time.
48. The guns and their equipments are to be kept as dry as possible, and no salt water used in cleaning them.
49. If he shall discover any articles to be injured, or liable to injury from any cause, he will ask, in writing, for a survey to be held, to determine the amount, cause, or liability of any of the stores or equipments to damage or deterioration; a copy of this request and report of survey to be furnished to him as a voucher, by the officer ordering the survey.
50. Whenever the magazines or shell-rooms are opened, he is to take every precaution to guard against accident by fire; to examine particularly that all the men stationed in any way in or about the magazine, embracing all stationed within the magazine screen, put on the magazine dress and shoes, and on no account have any thing metallic about them, and that no improper articles are introduced. He will also see that all the articles required for sweeping and removing loose powder are at hand, and that those operations are performed before the magazine is closed.
51. The tanks are never to be opened unless by special order, or when powder is actually required for service; and then no more of the lids are to be unscrewed than is necessary for immediate supply. The strictest attention to this regulation is required of the Gunner, as experience has proved that the preservation of the powder in good condition depends upon the entire
