play, the beat is slower, and conversely. The English government in 1714 offered a reward of £ 20,000 for the discovery of a correct mode of ascertaining the longitude at sea. Harrison made four time-pieces within the years above cited, and in 1764 and following years received £ 24,000 for his improvements. (See chronometer.) The special point of novelty was the compensation balance, which was constructed to run at an equal rate under changes of temperature. It is formed of two metals, in partial vacuum at that point, and thus utilize the natural pressure of the atmosphere. Steam-engine condensers are of several forms:— The injection condenser was invented by Watt, who was a philosophical-instrument maker in Glasgow, when, in 1764, a model of an atmospheric engine (Newcomen's), belonging to the University of Glasgow, was brought to him to repair; the cylinder of this model was 2 inches in diameter, and 6 inches in length. Having repaired damages, whatever they were, the li

e1829. Laced-stocking. A bandage support for varicose veins, weak legs, etc. Lace-mak′ing ma-chine′. Lace is a delicate kind of network composed of silk, flax, or cotton threads, twisted or plaited together. See lace. The meshes are of an hexagonal figure, in which thick threads are also interwoven to form the pattern, according to some design; and these threads, which are called gymp, form the ornament of the lace. The point-net frame was invented by Morris (England) in 1764, and is a variety of the stocking-frame, making a stitch or loop like that of a stocking, and formed by a continuance of one thread. The thread is by the machine formed into loops, a whole course at once, by pressing it down alternately over and under between a number of parallel needles. A second course is then made of similar loops on the same needles, and the loops of the first are drawn through those of the second in such a manner as to form meshes by retaining the first loops; the seco

Mold-board. 1. (Plow.) A curved plate extending back of the share, for overturning the furrowslice. The mold-board, as its name indicates, was originally of wood, and was first made of iron by James Small, of Berwickshire, Scotland, about 1764. He was the first to make a complete plow of iron and steel, all but the hand-holds for the grasp of the plowman. Plows are called right or left, according to the direction in which the furrow-slice is laid. Double mold-board plows are those servoir to the paper. Mu′sic-print′ing. Music was first printed by types on which the ledger lines were cast. The font displayed all possible variations of character and position. In 1720, music was engraved on plates. Breitkopf's type, 1764, had the ledger lines on separate type. Reinhard printed the ledger lines from engraved plates, and the notes from type at a second pull. Another and more modern plan is to put up the ledger lines in rules and cast the type so as to admit of t

or it is a cutting-wheel in advance. The draft-rod is not universal, but adds to the strength of the implement. The mold-board was, as its name indicates, formerly of wood. It was first made of iron by Small of Berwickshire, Scotland, about 1764. The chilled cast-iron plowshare was patented by Ransome of Ipswich, England, 1803. The under side and points are hardened, and the top wears away, leaving a comparatively thin edge of hard, chilled iron. This is an imitation of the provisionmed Effendi, in 1721; the first press in Annapolis, Md., was in 1726; Williamsburg, Va., 1729; Charleston, S. C., 1730; Newport, R. I., 1732; Halifax, N. S., 1751; Newbern, N. C., 1755; Portsmouth, N. H., 1756; Savannah, Ga., 1763; Quebec, Canada, 1764. The first press west of the Alleghany range was in Cincinnati, 1793. The first press west of the Mississippi, in St. Louis, 1808. Stereotyping was invented by William Ged of Edinburgh, in 1725; inking-rollers, by Nicholson; composition inkin

them automatically. Hence the valve motion. For the first time, the engine worked by itself. With the exception of Smeaton's improvements in details, the Newcomen engine remained in the state to which its inventor had brought it, from 1710 to 1764, about which time Watt appeared. Desaguliers' steam-engine, invented about 1716, was substantially similar to Savery's. The steam pressed directly upon the water to drive it up the eduction-pipe. Cutting off the steam caused the steam in the w and previously desponding friend, was proud of his vocation, and is described by Boswell as an iron chieftain, with 700 work-people, and the father of his tribe. The works of Boulton — afterward Boulton and Watt — were established in Birmingham, 1764. Steamengines were made there in 1774. The first trial of the Watt engine took place in Cornwall under the inventor's supervision. The sea had broken into a copper-mine in that county, and the owners were unable to cope with the waters.

-box rises, and the yarns are wound spirally on the reel; the movement is then reversed, and the box descending by its own weight, a spiral layer is laid on in the opposite direction, and so on until the yarns are all wound off the bobbins. See also previous article. Warping-mill. Warp-lace. Lace having a warp which is crossed obliquely by two weft-threads. See also bobbinet. The oldest lace has a knit ground, and the ornament worked by the needle. The oldest machine, made in 1764, was a modification of the stocking-frame, and was called the frame-looped net machine; six-sided meshes could be made, which held their form when starched, but shrunk like crape when damp. To this succeeded the warp-frame, which had looped stitches, but had so much more solidity that it could be cut and stitched like cloth. In 1810, there were 400 warp-looms at work making Mechlin net. Heathcote patented his first twist-net machine in 1805, and Lord Lyndhurst pronounced it the most wo
