e red shoes. Red and purple were regal, and red is yet a cardinal color. The Etruscan augurs wore jack-boots. The Lamas of Tartary wear red boots and yellow cloaks. They leave their boots in the vestibules of the temples. So do the Turks. The latter brought the practice from Central Asia. There bought a pair of boots; cost me 30 s. — Pepys, 1662. The boot and shoe making business, more particularly since the introduction of pegs, which are said to have been invented by Joseph Walker, of Hopkinton, Mass., about the year 1818, has become a very extensive and important branch of manufacture, machinery being employed in nearly all the operations connected with the business. The first application of machinery in shoemaking is due to the celebrated Brunel, who devised a series of machines, which were operated by invalid soldiers belonging to Chelsea Hospital. The shoe passed through a number of hands before being finished; the operation which each man had to perform was

he required thickness upon fabric, by rolls of even motion; and the rubber fabric is then cut into pieces according to pattern, for boot or shoe soles, etc. In′dia-rub′ber spring. The first known use of india-rubber for springs is in Lacy's English patent of 1825. He employed blocks of rubber with interposed plates of iron. Melville, 1844, obtained a patent for hollow spheres of rubber, enclosing air and separated by disks of wood or metal, the whole enclosed in iron cases. In 1845, Walker and Mills patented rubber bags filled with air and enclosed in a case for use as springs. Fuller, 1845, cylindrical rings of rubber having perforated disks between them, and a guide-rod passing through the whole. These had a tendency to swell out at the center under pressure, breaking or injuring the material. To remedy this defect, Spencer, 1852, 1853, formed the rubber rings of the shape which they would assume under pressure, and surrounded them with an annulus of iron. These have bee

und formed of nitrate of silver, ammonia, and tartaric acid. The solution is applied to a polished glass, and silver is precipitated to the amount of about one pennyweight to each square foot of glass. It is then protected by a dark varnish. Walker (1869) uses the same ingredients in somewhat different proportions. The surface of the glass is thoroughly polished with whiting and washed with distilled water, when the plate is heated to about 120°, and the solution applied. After the silver. (Printing.)

The application of compressed air to driving the machinery of a locomotive does not constitute the line an Atmospheric Railway as ordinarily understood. See air-engine; air-engine, compressed. See also pneumatic tube. Pneu-mat′ic spring. Air confined in bags and used as a spring in carriages is specified in the English patent of Walker and Mills, July 3, 1845. It has been used to receive the recoil of a gun in firing, to arrest the blow of a reciprocating bed in a printing-press, and in many other positions. Pneumatic car-spring.
