A NEW QUARTZ CRUSHER.

♦ [SYDNEY CORRESPONDENT OF ARGUS.] Victoria has so long taken the lead in gold-mining, and especially in that department of it which consists in quartz-crush-ing, that your miners will not readily believe in any new invention that cornea from Sydney. But there is on view at Greville's Rooms a little machine, which is said by some who profess to understand such matters to be a great improvement on the apparatus at present used. The inventor is Dr Been, a German medical man, with a natural turn for mechanics and engineering, and who has lately been residing at the Braidwood diggings. The principle of this new quartz-stamper is, that rapidity of action can compensate foi weight. There are three cams on t the horizontal shaft instead of the usual two, and the upward movement of the rod is resisted by the growiug pressure of a spring above. The suddenness and. smartness ol the blow when the stamper is sent down is such, that the work done is said to be equal to that of an ordinary stamper oi 6001 b weight falling a foot. One man can work the model, and the stamper will crush a ton of ordinary quartz in three hours. A public trial will be made shortly, 1 when those interested will have an opportunity of judging how far the machine wil i antwer on a larger scale and in continuous . work. It is certainly a very light anc . portable Apparatus, and a one-ton crushei will be a great convenience to prospectors i as it is easy to take to pieces and pin together, and can be lifted in and out of i \ dray, and carried about wherever bullocki i can travel.
