made considerable improvements upon tho or'.g'nal design, The j, battery stands nearly 7ft high, and occupies a space of a'cait -Ift square. A single h -ad battery i„, in proport,(i . to its size, : quul in power t<j three of the ordinary 9owt stamp batteries. It Las three grates or discharges, each Ift square, and strikes from 130 to 180 blowH per minute with a forco equal to from 10cwt to 12e.wt , but the blows can bo regulated from Icrvt to 30cwt. One of the great advantages <>f this new machine is its lightness and portability No part of the battery weighs uioro than 30owt, and that weight can be reduced to IScwt if required, so that a largo saving can be effected in cases win re the battery has to be taken a long distance into tM!n prior. Another advantage which the battery has over others of different makes is that prospectors at a siriull cost can place a single-head bitterv on an untried reef and prove the quality of the stone. In the event of the test being satisfactory they can then increase the battery up to twenty head if they so choose, each head being worked independently of the other. For this battery yet another improvement is claimed, aud that is thut warm water is constantly passing over the copper plates or tables, w Licit has the effect of always keeping the quicksilver alive, so that the gold is caught quicker than in the ordinary cold watertables. A two-stamp “ Goli-th ” buttery, which is said to be equal to an ordinary six-stamp machine, only weighs seven tons, whtreus a five-stamp battery of tho customary make is from I t to 1(1 tons in weight ll is easily placed in position, and when once its foundations arc laid tho stamper can bo put together by a mechanic, assisted by two laborers, within a week and bo ready for use. To work two stampers a 21 horse-power engine, with a G-horse power boiler, is required. The new battery will bo kept erected in Messrs Smith, Forrester and Go.’s for testing- quantities of stone of from 1 to 4 tons.
