lear, wipe the barrel dry and
pass into it an oiled rag. Fine flour of emery cloth is the best
article to clean the exterior of the barrel.

265. TO CLEAN THE LOCK.--Wipe every part with a moist rag, and then a
dry one; if any part of the interior shows rust, put a drop of oil on
the point or end of a piece of soft wood dipped into flour of emery;
rub out the rust and wipe the surface dry; then rub every part with a
slightly oiled rag.

266. TO CLEAN THE MOUNTINGS.--For iron and steel parts, use fine emery
moistened with oil, or emery cloth. For brass parts, use rotten-stone
moistened with vinegar or water, applied with a rag, brush, or stick;
oil or grease should be avoided. The dirt may be removed from the
screw-holes by screwing a piece of soft wood into them. Wipe all parts
with a linen rag, and leave the parts slightly oiled.

267. DISMOUNTING BY AN ARMORER.--The parts which are specially
assigned to be dismounted by an experienced armorer will be stated in
their regular order, following No. 8, viz.:

9th. Unscrew cone. 10th. Take out cone-seat screw, 11th. Take out
band-springs, using a wire punch. 12th. Take out the guard-screws. Be
careful that the screw-driver does not slip and mar the stock. 13th.
Remove the guard without injuring the wood at either end of the plate.
14th. Remove the side screw-washers with a drift-punch. 15th. Remove
the butt-plate. 16th. Remove the rear-sight. 17th. Turn out the
breech-screw by means of a "breech screw-wrench" suited to the tenon
of the screw. No other wrench should ever be used for this purpose,
and the barrel should be held in clamps neatly fitting the breech.

268. LOCK.--To take the lock apart: 1st. Cock the piece and apply the
spring-piece to the mainspring; give the thumb-screw a turn sufficient
to liberate the spring from the swivel and mainspring notch; remove
the spring. 2d. The sear-spring screw. 3d. The sear-screw and sear.
4th. The bridle-screw and bridle. 5th. The tumbler-screw. 6th. The
tumbler. This is driven out with a punch inserted in the screw-hole,
which at the same time liberates the hammer. 7th. Detach the
mainspring swivel from the tumbler with a drift-punch. 8th. Take out
the feed-finger and spring. 9th. The catch-spring and screw.

269. As a general rule, all parts of the musket are assembled in the
inverse order in which they are dismounted. Before replacing screws,
oil them slightly with good sperm oil, as inferior oil is converted
into a gu
