s of the dead-eyes through
the toe-link, for the purpose of securing the masts by the shrouds.
Also, the bolts which fasten the channel-plates to the ship's side.

CHAIN-CABLE COMPRESSOR. A curved arm of iron which revolves on a bolt
through an eye at one end, at the other is a larger eye in which a
tackle is hooked; it is used to bind the cable against the pipe through
which it is passing, and check it from running out too quickly.

CHAIN-CABLE CONTROLLER. A contrivance for the prevention of one part of
the chain riding on another while heaving in.

CHAIN-CABLES. Are not new; Caesar found them on the shores of the British
Channel. In 1818 I saw upwards of eighty sail of vessels with them at
Desenzano, on the Lago di Garda. They have all but superseded hemp
cables in recent times; they are divided into parts 15 fathoms in
length, which are connected by shackles, any one of which may be slipped
in emergency; at each 7-1/2 fathoms a swivel used to be inserted, but in
many cases they are now dispensed with.

CHAIN-CABLE SHACKLES. Used for coupling the parts of a chain-cable at
various lengths, so that they may be disconnected when circumstance
demands it.

CHAIN-HOOK. An iron rod with a handling-eye at one end, and a hook at
the other, for hauling the chain-cables about.

CHAIN-PIPE. An aperture through which a chain-cable passes from the
chain-well to the deck above.

CHAIN-PLATES. Plates of iron with their lower ends bolted to the ship's
sides under the channels, and to these plates the dead-eyes are
fastened; other plates lap over and secure them below. Formerly, and
still in great ships, the dead-eyes were linked to chain-pieces, and
from their being occasionally made in one plate they have obtained this
appellation.

CHAIN-PUMP. This is composed of two long metal tubes let down through
the decks somewhat apart from each other, but joined at their lower
ends, which are pierced with holes for the admission of water. Above the
upper part of the tubes is a sprocket-wheel worked by crank handles;
over this wheel, and passing through both tubes, is an endless chain,
furnished at certain distances with bucket valves or pistons, turning
round a friction-roller. The whole, when set in motion by means of the
crank handles, passing down one tube and up the other, raises the water
very rapidly.

CHAINS, properly CHAIN-WALES, or CHANNELS. Broad and thick planks
projecting horizontally from the ship's outside, to which t
