MINING.

Cure. —The crushing which is going on for this company at Tararu may be considered as highly satisfactory, when we state the following facts. On Friday afternoon, after about twenty tons of stone had been put through, a clean-up of the plate ama'ge.n gave as the result one hundred and thirty ounces of hard-squeezed amalgam—tins without touching the rip;.de3 or blanketings. Another clean-up and squeezing will take place to-morrow, and we shall watch the result with interest. As rega'ds the value of the blanketings f.om the stone put tlnongli, some idea may he arrived at when we state that one berdan, working for twenty four hours, gave a return of iweuty-iliree ounces o f good squeezed ann-Kgriu. We think that we are fully justified in putting down ■he value o? Hie crushing as at least two ounces to the ton, if not more. We must say that the result, so far, has surpassed our expectations, as the gold is very hard to bo seen while ciashing is gomg on.

SM'oING Beauty. —Yesterday morning, work was started at hailing out the shaft, which was full of water to within a few feet of the top. Up to last evening, they had succeeded in reducing the water to about five or s : x feet, having taken out over twenty feet of it. We are sorry to say, however, that the pudd'kig which was done some »• iiie since is of bitle or no use, arid that (lie wale" comes in through it at a great ride. When we come to consider that there is not an average of four inches of ebay between the timbers, we are not purposed at tip’s,*and we feel sure that the directors will have to do the whole thing over again, when, if they puddle with dry not tempered clay for snv eight inches or even a foot, we i nagine that the shaft can easily be rendered watertight. This is the expressed opinion of men learned in this sort of work, and those who have worked in ground much welter than this, and have yet got a dry shaft bv judic’ojs puddling. Now that the directors have started to work, we trust that they w»ll prosecute it vigorously, for it is an ahnost undoubted fact that the Br’ghi Smile reef strikes through their g-oiin(', and tins is weU worth spending a IK le money to look for.

Windsor Castle. —Yesterday morning some nice specimens wore taken from the leading slopes on the lode worked in this company’s low level, the stone showing excellent gold. The quantity was not great, some five or six pounds, hut the presence of gohl in quantities like this is most satisfactory. Now that the lode is being opened up by sloping, the manager expects to bo able to start crushing by to-mor-'ow, and to make it continuous, and lie lias every prospect of getting good ret;? ns, tbeie being a splendid block of ground to work out. Watchman. —The directors of tin's company have resolved to continue the driving of their low level tunnel by contract, instead of by wages men, ns heretofore done. They have accordingly called for tenders for driving two hundred and fifty feet fui ther, which will bring them close to the reef, and tiiey have appointed Mr W. C. Wright to act as the company’s surveyor and engineer. Bright Smile. —The management of this mine'have determined to try their utmost to get down with the shaft in spi'e of the heavy inflow of water, and to this end started bailing with fotirhorses ready to work six hour shifts! as hard as thej r could go. The idea was good, and we learn successful, as by last evening they had succeeded.in breaking the water, and put men on at once to continue sinking. That they will be able to continue to a sufficient depth for opening out another level for working on, we. fully believe, so that in the event of their having to erect machinery eventually, the mine will not be idle in the meantime, but will have blocks of ground ready at hand to

wo.lc at whilst the machinery is being put into posh ion, though if t hey only wait until the United Pumping Association cut their reef, we believe that they can go down to a much greater depth than they are working now, with comparaiivelj7 liitle trouble. Una. —The lode which has been cut in the low level tunnel has not yet been proved to be the main vein.' It is not at all similar in appearance to it as worked on above, and the lie even is different, in one place the b’e being southerly, and the other northerly, and this, though not proof, is strong evidence in favour of the two not being identical, but leads us to the belief that a strong feeder ftom the main lode has been cut through, and that a few feet more of driving will bring them on to the reef. Y T hen the reef is cut and opened up it will be of great advantage to the company, enabling them to keep their battery fully employed, in place of .vorking only lia'f time, as is now the case. Prince Imperial. —The gold from the crushing for this company has been melted, and lias turned out fifty-five ounces seven pennyweights and twelve grains. Waiotahi Tribute. —A small parcel of six ounces one pennyweight of melted gold was lodged on behalf of this company yesterday.
