Gun tackle

( Naut. ) A system of pulleys, consisting of two single blocks, one movable, the other fixed, the standing end of the fall being made fast to the movable block. It increases the power threefold. They are used on board ships, to run the guns out of the ports. Gunter's Chain, n . [From the inventor Edmund Gunter , an English mathematician, who lived 1581-1626.] The chain commonly used for measuring land. It is 66 feet, or 4 poles, in length, and consists of 100 links, each of which is joined to the adjacent one by 3 rings. The length of each link, including the connecting rings, is 7-92 inches. The advantage of this measure consists in the facility which it affords for numerical calculations. The English acre contains 4,840 sq. yds.; and Gunter's chain being 22 yds. in length, the square of which is 484, it follows that a square chain is exactly the tenth part of an acre. A square chain, again, contains 10,000square links, so that 100,000 square links are equal to an acre; consequently, the area of a field being estimated in square links, it is only nece ary to divide the result by 100,000, or to cut off the last five figures, to obtain the area expre ed in acres. G.8 Line. ( Math .) A logarithmic line engraved on scales, sectors, ., serving to perform the multiplication and division of numbers instrumentally, as a table of logarithms does arithmetically. The numbers are usually drawn on two separate rulers sliding against each other. In rough calculations this line affords considerable facilities.- G.'s Quadrant . A quadrant of a peculiar kind, adapted to the problems of finding the hour of the day, the sun's azimuth, and other common problems of the sphere.- A large plane scale, having various lines of numbers engraved on it, by means of which questions in navigation are resolved with the aid of a pair of compa es. It is usually called the Gunter by seamen. On one side of the scale the natural lines (as the line of chords, the line of sines, tangents, rhombs, .) are placed; on the other the corresponding logarithmic ones. Gun'tersville, formerly Gun'ter's Landing, in Alabama , a post-village, cap. of Marshall co., on the Tenne ee River, abt. 35 m. S.E. of Huntsville. Guntoor, ( goon - to or ',) a district of British India, W. of the Bay of Bengal, often called the Northern Circars: area, 4,950 sq. m. Prod. Grain, cotton, sugar, and paddy. Pop . 627,000.- Its capital, of same name, is situated in Lat. 16° 20′ N., Lon. 80° 30′ E.; pop . 25,700. Gun Town, a locality in Georgia , on the line of the Mobile and Ohio Railroad. Here, June 10, 1864, a National force of 12,000 men, commanded by Gen. Sturgis, was utterly routed by the Confederates, under Gen. For rest, losing about 3,500 men, and everything except arms. tine, 10; Rack a rock, 9-36; Emmensite, 5.49; Gun-Gunwale, Gunnel, (gun'nel,) n. [From gun, and cotton, 3:16; U. S. rifle powder, 1.72. These results, however, do not fully indicate the value of these explosives for military purposes, in which other qualities of value may take precedence of explosive power. Of the various advantages which are claimed for smokele powders in war, the greatest is that of the clear vision of the field which they give to commanding officers, who thus are enabled to see exigencies as they arise, and may often prevent disasters by more timely preparation for them. wale , because the guns of the spar-deck are pointed thence.] ( Naut .) The lower portion of any gun-port of a ship; the upper portion of the side of a ve el; the uppermost wale of a ship.
