uitable vessel, subjecting both vessel and contents to a red heat, and allowing the whole to cool from six to twelve hours, according to the size of the nails and tube, and maintaining the vessel air-tight during the heating and cooling process. Much attention has been directed to the annealing of cast-iron car-wheels. The object is to make the web soft and tough, so as to withstand the jar and strain incident to use, and at the same time have a hardened rim which will bear the wear. Whitney, April 25, 1848, placed the wheels in a pile in a cylindrical pit or case in which they were closely covered and left to cool gradually. A nonconducting jacket protracted the period of cooling, and contributed to the effectiveness of the operation. Geisse, April 19, 1859. The wheels, while hot, are removed from the molds and piled in a cylindrical oven, where they are allowed to cool gradually. A blast of air is carried through the centers of the hubs, which, as the wheels are symmetri

A device, originally invented by Whitney, 1794, in which lint is picked from the seed by means of saw-teeth projecting through slits in the side of the chamber in which the seed-cotton is placed.

. A pump operated by windmill. 3. A coal-hoisting machine. See whin. 4. A snare for birds or animals. 5. A spirit distilled from grain and flavored with juniper berries. 6. A machine for separating cotton-fiber from the seeds. Eli Whitney's cotton-gin, invented in 1793, revolutionized the culture and manufacture of the fiber by providing a mode of putting it into merchantable order at a reasonable price. When done by hand, a man can clean but one pound per day. The roller-giit away, while the seed is detained by a comb. The combing instrument used in the Spanish colonies for removing the seed from the cotton-fiber is called almarraes. The syllable al indicates the Saracenic origin of the tool and its uses. In Whitney's saw-gin (A) the cotton is placed in a long and narrow hopper, one side of which is formed by a grating of strong parallel wires 1/8 inch apart. Close to the hopper is a roller with circular saws 1 1/2 inches apart. These, as they revolve, pa
ping of the sheaf. Reaping and binding machines. Barta's self-binder (1871) has also worked successfully in the field. It uses cord, makes a square knot, and binds a gavel of any size, even no larger than the arm. The following automatic binders may also be consulted:— Bowron, January 16, 1872, cord band, secured by wire. Carpenter, December 22, 1868, wire. Clinton, July 13, 1869, cord.

ire. Admirable examples are to be found in the American Watch Company's works at Waltham, where jewel and other screws are made by perfectly automatic operations from wire fed from spools. Fig. 7276 shows one on a larger scale by Pratt and Whitney, of Hartford, Conn. Wire-fence. Hurdles of woven wire, or wire stretched from post to post. Fig. 7277 shows one form in which the sections are strained between movable self-supporting posts. In Fig. 7278, the wires are attached to thp, and a triangular trestle supports each corner transversely. The capstan-blocks are separate, so as to allow the independent tightening of each wire, and are turned by radial arms which are secured by wires to the nearest post. Pratt and Whitney's wire-feed screw-machine. Fig. 7279 is an iron post for wire-fences. The posts are made of strap-iron bent around at the top and spread at the bottom; the sides are connected by stay-rods, and are braced at the angle near the foot by angul
