Here are instructions on polishing a pair of ox horns. Remove all roughness from the horns by means of a spokeshave or rasp, followed by a scraper, a knife, the side of a chisel, a wood scraper, etc. Then go over them with sandpaper or glasspaper, using coarse paper first, then finer, and the finest last. Pumice powder should next be used, followed by the dust removed from the horn; these can be applied on a rag dipped in oil. Then apply putty powder in the same way, followed by whiting in. listened with vinegar. Now use dry cloths, commencing with a. coarse one and finishing with a soft one, or even tissue paper. Lastly, use the bare palm of the hand. In applying each of the above-mentioned substances plenty of "elbow grease" must be used, and the work must be very carefully dusted between successive stages to remove any trace of coarse grit. The use of a lathe with calico mops, etc., if procurable, will save time and labour and will give a better result.
