TRAVELLER-IRON. To a cutter's fore-sail, boom-mainsail, or spanker-boom; generally termed traveller horse. (See [Horse].)

TRAVELLING-BACKSTAYS, are generally the breast-backstays, which set up with a runner purchase in the channels on the weather side; that to leeward is let go in stays. The traveller is a strong parrel-strop which passes round the mast, and through two thimbles of which the breast backstays reeve. As the yard is hoisted this slips up, but when a reef is taken in it is rode down by the feet of two men close to the tye-block, and thus supports the mast from the top-rim to the parrel.

TRAVELLING-GUYS. The jib traveller guys are seized on to the traveller, and are shortened in and set up when the jib is eased in.

TRAVELLING-MARTINGALE. A similar contrivance adapted to a martingale to support the jib-boom in that particular part where the jib-tack is fixed. (See [Martingale].)

TRAVERSE. Denotes the several courses a ship makes under the changes of wind or manœuvres. It is self-evident that if she steered a course there would be no traverse. But her course being north, and the wind from the north, it is evident she could have but two courses open to her, E.N.E., or W.N.W. The reduction of the distances run on each course, corrected for variation and lee-way, constitutes the traverse table, from which the reckoning is deduced each day up to noon. From this zig-zag set of lines we have the term [Tom Cox's traverse] (which see). Also, in fortification, a mound, often of parapet form, raised to cover from enfilade or reverse fire. Also, to traverse a gun or mortar. To alter its direction from right to left, or vice versâ, with handspikes, tackles, &c.

TRAVERSE A YARD, To. To get it fore and aft.

TRAVERSE-BOARD. A thin circular piece of board, marked with all the points of the compass, and having eight holes bored in each, and eight small pegs hanging from the centre of the board. It is used to determine the different courses run by a ship during a watch, by sticking one peg into the point on which the ship has run each half hour. It is useful in light and variable winds.

TRAVERSE-HORSE. See [Jack-stays].

TRAVERSE QUESTIONS. Cross examinations at a court-martial.

TRAVERSE SAILING. Resolving a traverse is merely a general term for the determination of a single course equivalent to a series of successive courses steered, whatever be the manner of finding the lengths of the lines forming the triangles.
