Mr. John Good hall has forwarded a lengthy report to tho legal manager of the Carbine mine, Kuaotunu, with regard to the trial crushing of quartz at the Moana taiari battery. He states thab three classes of ore wero forwarded for treatment. No. 1 is 5 tone of beat ore, and 401b of picked stone from the leader ; No. 2 is IOJ ions of second clas3 oro from the leader ; and No. 3, ten tons of ore from the main lode. Parcels of No. 2 and No. 3 ore had alroady been treated at the Kuaotunu Quartz Crush ing Company's batten/, and parcala of No. 2 and No. 5 were also senb so as to teat tho ativing power of bho Kuaotunu battery. Ab that battery the stamped ore passed over mercury tablee and tho tailings wonb direct through Price's pans. Ab the Moanabaiari battery the stamped ore pasaed over mercury tables and blanket shakings, and the blanketings were washed off in berdans. The tailings were gathered in pits and treated in one of Eraser's pans. Ib appears from the Kuaotunu crushing re turns thab 2dk tons of No. 2 oro and 14 tons of No. 3 ore were put through. On inquiry MrGoodhall found that 7 largo bags of quarte were accepted as one ton at the Kuaotunu battery, while 20 small ones wero taken as a ton at the Moanataiari battery. By measurement ib \Vas found that 3.V smull bags wero equal to one largo bag ; thus thab at"the Kuaotunu battery would bo ns 23 l-3rd to 20 ab tho Moanataiari battery. So instead of 23A tons of No. 2, and 14 of No. 3, the figures will bo 34£ and 16.J, and the result was aa follows :—No. 2, yielded 80oz lldwb of molted gold, equal to 2oz 6dvvb per ton : and No. 3, 16 j tons, 13oz 9dwt, equal to 17dwt. The total results from the Moanataiari battery were —including what was saved from tho pans—No. 1, 5 tons, 107oz sdwt, equal to 21oz 9dwt per ton ; No. 2, tons, '230z 19dwt, equal to 2oz 6dwt per ton ; and No. 3, 10 tons, 7oz 9dwt, equal to 15dwt per ton. It will be seen that with regard to the No. 2 parcel both returns aro equal, while in No.
