-gear, with a worm-wheel working in a mortise made through the outer ring. Duplex Pump′ing-engine. An arrangement in which two steam-engines of equal dimensions are placed side by side, one operating the steam-valves of the other. The Worthington compound engine illustrated is composed of two steam-engines each working a pump. Each engine has two steam-pistons, which operate in the smaller high-pressure and the larger low-pressure cylinder respectively, on the same rod, which is prol engines cited: — Brooklyn, No. 1, double-acting beam60,140,700 Belleville (Jersey City), Cornish62,823,300 Hartford (3 experiments), crank58,779,300 to 64,669,400 Brooklyn, No. 3, double-acting beam72,000,000 Cambridge (2 experiments), Worthington double-cylinder, not duplex66,941,100 to 67,574,600 Spring Garden (Philadelphia), Cornish58,905,300 The dity or useful effect of the Cornish pumpingengine has been more closely observed and recorded than that of any other engine.

subsequently used actual pressure of steam, was the first to use it expansively by cutting off at a part of the stroke, and also invented double-action engines in which the steam was admitted to alternate sides of the piston, making both motions effective. He made drawings for this in 1774, and exhibited it in 1782. He called it a double-engine, which must not be confounded with the doublecylinder engine of Hornblower of Penryhn, patented in 1781, revived by Woolf, and much improved by Worthington. See plate opposite page 763. Oliver Evans of Philadelphia has hardly had sufficient credit for his part in the matter, but he struggled for many years to make his townsmen believe that the high-pressure, double-acting engine was to be the engine of the future, both on roads and boats. He was active in the running of his hobby from 1787 to 1803, and in the former year obtained a patent from the State of Maryland for steam-carriages on common roads. His townsmen thought him crazy, an

ne, most of which, if not all, came from Persia. Smaller trellises, for garden work, are network frames, for tomatoes peas, and many ornamental climbers; cylindrical, pyramidal, columnar, or fan-like trellises for climbers. Special devices are formed for permanent ground-sockets with shifting poles. For upper structures, hinged so as to be laid down on the ground to be covered up with matting or straw for winter protection of tender grapes, or covered with earth as practiced by General Worthington of Chillicothe, Ohio, with his fig-trees. Other devices are for anchoring posts, or staying them with guys, or straining the wires of the trellis; guards to keep insects from climbing posts; claw bars and jacks for pulling posts and poles. The devices are numerous in each specific line, and we must be content with this mere hint of the direction of invention. Tre′loob-ing. （Mining.) See tossing. Trem′o-lo. （Music.)
