Many useful tools have been ground and cut, the files require to be annealed. invented for performing mechanical operations, This process is generally performed by piling up which consist of a number of wedges or teeth, a great quantity together in a furnace for the which may be conceived to stand upon, or rise purpose, and heating them red hot; suffering out of a flat or curved metallic surface. When them afterwards to cool slowly; on the whole these teeth are formed on the edge of a plate, a very objectionable method, since the surface the instrument is called a saw (see Saw); but of steel, when heated red hot in the open air, when they are formed ipon a broad surface, it is so liable to oxidation. A superior method constitutes what is denominated a file. The of annealing is practised by some file-makers, comb-makers use a tool of this description, and, since hardness in a file is so essential a procalled a quonet, having coarse single teeth, to perty, it ought to be generally adopted.

The fire is made to passes round his feet, which are introduced into play on every side of the vessel, as gradually the strap on each side in the same manner as ind uniformly as possible, till the whole mass stirrups are used. The file-cutter, therefore, becomes red hot.
