another to supply the after
half, will be all-sufficient.

185. For each chain of passing-scuttles there will probably have to
be--

One man in the magazine to deliver charges from the tanks.

One man in the passage to receive and pass those charges through the
scuttle in the orlop or berth deck.

One man at the passage-scuttle on the orlop or berth deck, to receive
the charges and pass them to the screen.

One man just outside of the screen, to receive the charges through a
flapped hole therein, and put them in the empty passing-boxes.

One, two, or three Runner-boys (according to the distance) to run, on
the orlop or berth deck, with full passing-boxes, from the screen to
the scuttles through the deck, and back again with the empty boxes to
the screen.

One man, a very careful one, at the bottom of the canvas chute, to
receive the empty passing-boxes, strike them, in an inverted position,
over the fire-tub, and inspect them carefully before allowing them to
be taken away to be replenished.

One man, on the orlop or berth deck, at the passing-scuttle through
the deck above, to pass up full boxes.

One man at the passing-scuttle on the next deck above the orlop or
berth deck, to receive and pass up full boxes, or, in the case of a
single-deck vessel, or of distribution on the main deck of a frigate,
or on the lower deck of a ship-of-the-line, to receive and deliver
them to Powder-boys.

One man at the passing-scuttle on the second deck above the orlop or
berth deck, to receive and pass up full boxes; or, in the case of a
frigate, or distribution on the main deck of a ship-of-the-line of two
decks, to receive and deliver them to Powder-boys.

And one man at the passing-scuttle on the third deck above the orlop,
to receive and deliver full boxes to Powder-boys on the spar-deck of a
ship-of-the-line of two decks.

Thus each chain of scuttles will require--

Seven men to supply its guns on the first deck above; as, for example,
the lower deck of a ship-of-the-line, the main deck of a frigate, or
the spar-deck of a sloop-of-war, or other single-deck vessel.

Eight men for the spar-deck of a frigate, for the main deck of a
ship-of-the-line of two decks, or for the middle gun-deck of a
ship-of-the-line of three decks.

Nine men for the spar-deck of a ship-of-the-line of two decks, or for
the main deck of a ship-of-the line of three decks.

And ten men for the spar-deck of a ship-of-the-line of three decks.
