nd let
the gun go out the port. As soon as the gun is perpendicular to the
purchase, unhook the garnet and lower the gun into the lighter, or on
the wharf, as the case may be.

If the gun is to be taken out over all, the stay-tackle is to be
substituted for the garnet, only it is to be hooked to the same end of
the slings as the gun-purchase, and the lashing on the slings is to be
passed around the chase of the gun, as near the trunnions as possible,
without being in the way of the brackets.

MANNER OF USING THE GRIOLET PURCHASE FOR DISMOUNTING OR MOUNTING GUNS
ON COVERED DECKS.

507. In practice, guns are rarely shifted from one carriage to another
during action: it is only during a cessation of firing. While the
action is going on, the crew of a disabled gun are more usefully
employed in replacing the killed and wounded. Furthermore, spare
carriages are not so numerous as to permit this operation to be
performed frequently. Nevertheless, each gun's crew should be
thoroughly exercised, in order to develop their strength and skill.

508. The gun is to be run in, in the direction required to bring the
muzzle under the housing-bolt, and the breech under the hole bored in
the deck to receive the screw-bolt of the upper block of the
breech-purchase. This hole should be bored through the plank in the
deck, as nearly abreast the middle of the port as the beams will
allow, giving the block room to play clear of the beams and carlings.

With a gun's crew of twelve men the operation may be performed as
follows:

At the word "Stand by to dismount!" the Quarter-Gunner of the division
on the deck above that in which the gun is to be dismounted removes
the screw-tap, and stands ready to place the washer, key and un-key
the bolt of the breech-purchase block.

All the numbers, except 1, 2, 3, and 4, man the train-tackle.

No. 1 gives the word "Run in!"

While the gun is coming in, Nos. 1 and 2 remove breeching from jaws of
cascabel, and 7 and 8 remove it from side-shackle. Nos. 1 and 2 throw
its bight over the reinforce. No. 1 removes sight-bar and screws up
the thumb-screw firmly.

When the gun is in position--Nos. 1 and 2 adjust upper and lower block
of breech-purchase and secure the latter with the cascabel-pin. Nos. 3
and 4 chock fore-trucks, provide muzzle-purchase, and, assisted if
necessary by 5 and 6, adjust its upper block. Nos. 5 and 6 unshackle
breeching from ship's side, and shove toggle-block of muzzle-pu
