OurWaipu correspondent! writes Last week I took the opportunity of visiting the paint mill erected by Mr. J. McLean, at the limestone hills, and was very courteously received, and shown over the works by the manager, Mr. Walker. The works are situated on an education reserve, the site of what was formerly known as, the Cave school, where a fine stream of water exists, which has been dammed for the purpose of supplying driving power to an undershot wheel of 22ft diameter, which operates the grinding machinery. The pan used for grinning is lift Gin in diameter, inside nf which have been arranged four radial arms that give motion to several large stones which travel over the paved bottom of the pan, and reduce the materials to the required degree of fineness. The practice is to charge the pan with about three-quarters of a ton of hematite ore, and wet-grind it for twenty-four hours, and then drain it off into another vat, where it is subjected to the process of elutriation, so that only the very finest partioles are drawn off and kilndried, before being packed for market. The mill is very complete on a small scale for attaining the ends desired, and the manager claims to be aole to supply paints wish far less grit in their composition than any of the same kind that are at present on the market contains. Manganese, whioh exists in large quantities near the works, is being ground, and produces a paint with a coppery-black tint, which is said to be a very good preservative for the bottom of boats. A large quantity of feldspar has been ground and mixed with a fine, white clay that is found in the neighbourhood, which the manager is very anxious to have experiments made with by potters, as he is confident it would produce a superior quality of pottery, and he would gladly forward quantities of the material free of charge to anyone willing to experiment with it. High hopes are entertained of developing a successful industry in connection with the hematite and manganese, ores, which are found in large quantities in close proximity to the works. I discovered many years ago (says an American farmer) that wood. could be made to last longer than iron in the ground, through a process so simple that it was not well to make a stir about it. I would as soon have poplar, bass-wood, or ash as any: other kind of timber for fence-posts. _ I have taken out bass-wood posts after having been set seven years that wore as sound when taken; out as when first put in the ground. Time and weather seem to have no . effect on them. The posts can be prepared for less than two cents apiece. '• This ■ is the recipe:—Take boiled linseed oil, and stir pulverised coal to the consistency of paint. Put a coat of this oyer the timber, and there is not a man who will live to see ib rot. Where sound durable timber is scarce in any locality, and.other timbers abound, the above mode of treating posts is woll worth a trial. . .' ; : Agricultural show entries close to-morrow.
