Patent Stamp Battery.

The Tarrengower Times, 14th August, reports, that " quite a gathering of practical men from Mvidon, Bendigo, and elsewhere, took place at Thornhill'-s reo ? on Monday afternoon, the occasion being the working of the new patent battery of"stamps recently imported from England by the Thornill's Reef Gold-mining Company. The battery consists of two stamps, each having a cylinder or jacket worked by a crank overhead, which causes the stamp shank to be acted upon by compressed air, the shank thus becoming a veritable piston rod, and working at speed and in a manner somewhat similar to the piston rod of a locomotive cylinder, the motive power being the compressed air derived from the action of the crank overhead. It was very obvious to those present that very great advantages would result'from the concentration of so much crushing power (the battery of two stamps being calculated to crush 120 tons per week), within such small space, from the very little motive power required, and from the low price at which the workmanship can be supplied. All present admired its neatness and compactness, but the more cautious are desirous of seeing it subjected to mmths of real work before committing themselves to an opinion of its merits. We think it is only a question of wear and tear, and should it bear the test of time and steady work in this respect, there is little doubt of its superseding the stamp batteries now in :use."
