Eiiminated-Econom Methods.
 A 60-ton concentrating plant is now being installed at the Yeager Canyon Copper company's property in Yaeger Canyon. It will consist of No. 2 Austin crusher a set of 14x27 ruff ing rolls, set of high speed 30x6 rolls. two 36-foot elevators. one Bart lett concentrating table. one Card ta- tle. three of the latest improved VII Hey tables. three Wilfley sinners, four improved impact screens Shallenge belt driven feeders and an S0-horse power Frost engine. and will com prise the latest and most up-to-Gate plant in operation in this part of the country. The rapid work that has heen accomplished under the direc- ton of the company's manager, MT. J B. Tomlinson. a careful student of geological conditions. and thorough practical miner. has elicited the admi ration of the country's mining frater- nifty. This new plant is a strictly a wet process and arranged in such a manner that the troubles from shines will be made away with.
 Mir Tomlinson has spent much time in the study of ways and means by which the yeager canyon ore could be treated successfully. and has de cided upon this method which is combination of well known processes arranged to meet the requirements. W. w. Elliott. the well known mill constructor. has been an able assist ant of MT. Tomlinson in perfecting the plans and detais of the plant.
 Following is a short description of the new mill which vii give an idea |of the arrangement of the various parts without going into technical description. which space will net al low at this time:
 The ore. as it comes from the stor- age bins. at the mouth of the shaft. which is about 150 feet from the mill, first goes into the scale room where every pound of ore is weighed, and then passes on to the storage bins below. The oversize being fed through crushers into bins then into Chal- ienge feeders and thence over i'm proved impact screens. where the oversize passes to the ruffling rolls The one-eighth Dorduce then passes l to the coarse elevator, the oversize er 20-mesh. passing to the fine ele- yetor: the unGersiZe. from 20mesh, passes to the impact screen ahead
 of the Wilfey tables.
 | The product from the rolls passes to
 the coarse elevator and is discharged upon the impact screens, which makes
 three distinct products; the over isiZe from the one-eighth passing
 back to the rolls; the one-eighth pro
 luct and oversize from 20-mesh pass
 ing to the Bartlett tables: the under s,ce from 20mesh screens passing to limpact screens ahead of the Wilfley | tables
 The tailings from the Bartiet table pass to the fine elevator anC lscreen. where the oversize from % 1 mesh passes 10 the fine rolls Tn
 undersize from 20-mesh. and the over size from 40-mesn passes to screens la. the head Of the Wilfley table. The
 ta;lings frcm the cares pass to tht
 screen ahead of the Wilfey table
 whict. makes three separations. 4
 mesh, 50 mesh, 100 mesh anr finer.
 Each particular sizing passes tt tWilfey tables and the tailings pas! lby gravity to the three Wilhey slim Iers-
 The mill building proper will b. l101 feet in length. over 40 feet II
 width and 56 feet form the loves
 level to the car track. The materia fused in the construction is of tim Der sufficiently large 10 insure
 good substantial structure. corrugal led iron will be used to enclose tn
 building. The flooring will be of e
 ment and all retaining walls and four , dations of concrete.
 The improved impact screen to b
 used here was devised by W w E liott. the builder of the plant: it : tused in place of the old time trou imel screen. being much more econon , licai as there is no more water re , lquired to operate the screens than i , |used in the crushing of ore The dc , lvice is such that after screening tn
 same water is then diverted back t the screen products in sufficien
 quantity to carry the pulp on to tn next machine.
 : As can be readily seen this prc lceSS IS q WdSNiuS anu SCTeeIiIS tTt - icess by which the shines are erad : Icated, and the silica in the ore is ';
 iGuced to very small amount. 1h
 iYeager Canyon Copper company ca /, talready be counted as one of the SUI lcessful companies of this section , flor, although it cannot be included i the list of dividend paying companie. Tor be classed as a large shipper, LII - less present indications are very d,
 lceiving it is likely to become a pa.
 ling company in the very near flu jure. The quantity and quality of tn
 lore is there in the mine and it onl ' Iremains for the new plant to be con + lpleted and in operation before th 3 lowners will be on the high road 9 prosperity.
