Waihi Company ; The erection of the stampeisand other gold saving appliances now in course of construction mo fast appro, iching completion, and when finishud will he as complete as any in the southern hemisphere. When our jepresentative visited this distiict a few days ago h« wns courteoubly shown over tho woiks by Mr Walker, a slioi t description of which will be interesting to our readers , The ore when (list tiucked into the mill will be tipped over ;; gr.tting nude of stiong iron lod.s with a two inch opening so us to sepiuate the fine from the eonrso, the lartei of which will be pa^Bed through the stone breakers, of which Lhete are two, but it is expected that one, working eight hours per day will be sufficient to reduce the quantity of quartz required to supply the stamper for 24 hours. The whole or' the quartz (coarse and fine) will bo dried and then trucked into hoppers at the back of the The stampers, of which then? iiie 30, of i'owt each, are on the diycrushing principe, fitted with self-feeding appaiatus, and wdi he dijwn at from 00 to 100 blows per minute. They will discharge through gauze or wire gratings into a receiving shoot, wheie an archiiuc_doan screw \\i\\ pass the ciushed stuff tow.uds tlie end, when the elevator will cairy it up and discharge it jt.to one of the Whitc-liowell rotary furnaces. After being thoroughly roasted it will fall into the cooling- chamber wJ\ere a powerful crane will turn and cany tho (ruckloads of roasted tailings into passes, ready to be fed into tlie combination pans for amalgamation. Not le&s than 10 settling ch.unbers are connected with the rotary furnace, live of hirg»j dimension measuring 10 feet in evpi;y direction, and five smaller ones in the flue on the surface befoie going up the chimney. The whole of this machinery will be driven by Price's Pelton wheels, preparations for which are now being made. The race bringing u\ the watei from the liver is 3TO chains in length. Che capacity of the face which is partly ground flnming and partly on trestle work is nine feet wide on top, four feet six inches in the bottom, and three feet six inches deep, having capacity to carry an immense vohmxa of water, which runs at the rate of three miles per hour, in order to secure a piessurc a shaft has been gunk 14 f3et by 1,0, feet (securely timbered), at the botton of wh.ich the, motois will be placed, the water haying a fall of 51 feet, In order to get rid of tho waste water after having done duty, a tail nice l<as been cut J Ol2 feet of a drive and 400 feet ppen cutting. As the watorfpidriving purposes is ta«ten from the Ohinoiiiuii river, there is no fear of its supply failing-, The whole of the machinery is rnott substantially constructed, and should bo worked with little expense, as every

part is almost working automatically. It is expected to Imve everything completed for constant working in about two or three weeks, unless it is decided to start with steam power until thp race is firisbed, In the mine the contractors for breaking the ore are making every preparation for startingfr brpnk out as spon as thp mill starts. Some 20Q0 tons are on the surface awniting treatment. — Advertiser.
