STOWAGE. An important art more practised than understood, for the stower seldom consults the specialities of the vessel's construction; it is the general disposition of the ballast, cargo, &c., contained in a ship's hold, with regard to their shape, size, or solidity, agreeably to the form of the vessel, and its probable centre of gravity. A badly stowed vessel cannot be properly handled, and is indeed dangerous to the lives of all on board. Owners and masters are legally liable to the losses by bad stowage or deficient dunnage.

STRANDED. A rope is stranded when one of its strands is broken by chafing, or by a strain. A vessel is stranded when driven on shore, in which case the justices of the peace may call in assistance. The term "stranded on the beach," is not so incorrect as has been asserted; and comes under the usual exception in charter-parties and bills of lading, of "all and every dangers of the seas, rivers, and navigation of whatsoever nature or kind;" and in all policies of insurance it falls under the general words of "all other perils, losses, or misfortunes," against the risk of which the insurance is made.

SUBMARINE THERMOMETER. An instrument for trying the temperature of the sea at different depths. It consists of a hollow weighted cylinder in which a Six's thermometer is placed; the cylinder being provided with a valve at each end, opening upwards, so that as it sinks the valves open, allowing a free course of water through the cylinder: when it reaches the required depth the line is checked and the valves close; it is then hauled gently in, and the thermometer reaches the surface surrounded by water of the required depth, indicating its temperature.

SWINGING-BOOM. The spar which stretches the foot of a lower studding-sail; in large ships they have goose-necks in one end which hook to the foremost part of the fore-chains to iron strops fitted for the purpose. In port they are hooked to bolts at the bends, which, by bringing them lower down, enables the boats to ride easier by them as guest-warp booms.
