If one has access to a polishing wheel the process is shortened greatly. The same materials are used as in polishing by hand and in the same order. D. Emery of exceeding fineness may be easily prepared as follows: Fill a high narrow vessel like a preserving jar, nearly full of water, and put into it about 200 pframmes of ordinary flour of emery. Agitate thoroughly, and after the vessel has stood half a minute pour off the liquid into another dish. Add more water to the first vessel and agitate again, and pour off the liquid as before. The larger particles sink first, and hence the emery in the water poured off is much finer than that left. Allow the emery to settle from the first and second washings and pour off the water and dry the emery. Several grades may he obtained in this simple way. E.'Instruments maybe very nicely polished by using, in place of rouge, the fine whitish ashes that may be found in the upper parts of stoves in which anthracite coal is burned. F. If rouge is added to the oiled leather used for wiping the instruments after they are washed (§ 178), the polish may be retained indefinitely. SHARPENING INSTRUMENTS. § 184.
