QUINCY MOVES TOWARD OTHER
 MINE TRACTS

 HOUGHTON, Mich, Feb. S.-Quin- cy expansion northwaTd in the Mes
 nard and Pontiac tracts is rapidly
 taking shape. This portion is separat-
 ed from old Quincy on surface by
 Franklin, but they have underground
 connections below FrankIin's boundary
 corner. No. or Mesnard shaft has
 reached upwards of 4000 feet in depth
 and the lode there is locking as good
 as in any part of the mine.
 Diamond drilling last fall located
 the outcrop and dip of the lode north ward and the site was selected for No. 9 or Pontiac shaft, 2,60O feet north of
 No. s. In the machine shops the boil
 CT engine and ther equipment are be- ing prepared to install there and the sinking will start as soon as the spring
 weather permits. The shaft will be | opened full size for working and not for exploration. There is no overbur-
 den.
 The installation Of the air com pressor now on the ground will com plete No S's permanent equipment. The concrete foundation, 12 feet deep; was finished this week. The com
 pressor is the rolling mill type, with
 continuous frame and base extending under all the cylinders, giving it un- usual strength. It is cross compound { and two stage. with a capacity to ac-
 tuate 65 drills. Three boilers of 25O horsepower each will be installed for the compressor, giving No. s an equipment of ten boilers.
 Additional economy nas been secur- [ ed by consolidating the steam supply in one boiler house and raising the pressure to 150 pounds. The same pressure will be used at No. 8 compres- scr. The new equipment will give : Quincy air capacity for considerable f over 5000 drills.
 3 Quincy No shaft rockhouse has its - interior remodeled, reducing the num- r bar of men and increasing the bin cap 7 acity to TOO tons of rock, from 150 . tons. Previous to 1905 it required 2S 3 men to handle the rock output of 24 hours at No. '. Improvements in that , year reduced this number to 16 men , With the system just finished the out i. put of 24 hours is handled by five men.
 The rock is dumped into an immense 2 steel hopper, from the throat of which . it is fed to two giant crushers. One
 man at each crusher controls the pneu- matic gate and picks out the mass copper. The masses are cleaned of 7 gangue rock by steel hammer. Eth 1. CT crusher is capable of taking care of : the entire output for a limited time i. and repairs can be made without in
 terrupting the hoist.
 1, Quincy No. shaft is to have steel rockhouse in place of the frame one
 now in service. It will be of the mod . ern type The mine has twenty cleo !. tric locomotives in service under !. ground.
 . Arcadian is sinking in the rock after . penetrating 75 feet of overbuTden in 2 the vertical shaft that will explore the 2 eastern part of the property. The !, shaft recently discontinued drove a : crosscut eastward for 1000 feet and , the new shaft is about midway be
 tween the limit of ground reached by l. the crosscut and the eastern boun'
 dary. From an undetermined depth -Ia crosscut will be driven east and ! west to explore the remainder of the tract. A number of fairly encourag-
 ing lodes containing copper were op- :, ened by the former crosscut, but it is ' planned to map all of the lodes by lcrosscutting before the development ' is centered upon any one.
 Rhode Island is penetrating the most 7 encouraging stretch of copper ground found during it's career, driving to- war dthe south at depth of 1275 feet : on the Pewabic icde, thus approach ing the Franklin Juniors good show E ing on the same lode. The drift was l. started last April and has been carried U 625 feet, throughout a large part Gi U which good stoping ground has beer
 opened. No stopes have been cut out
 the object being to gain distance as F rapidly as possible. A drift north al r. the same level is in 1000 feet There ? the ground Is not so good in copper II but the character of the rock is en 2 couraging. Two drills are in service g The lode varies in width from six tC T. fourteen feet.
 T. Rhode Island has discontinued all 2 diamond drilling. It had a drill under Q ground some time ago which pene If trated the Pewabie East and two un Is named copper bearing amygdaloids l. the Mesnard epidote and the Aiioues Ii conglomerate. Later the drill was pu' D. on surface to determine the extension l. and dip of the Kearsage lode, whicf l- had been previously located. It wa: s then removed to the Quincy, where d it located the lode for opening No. ol y Pontiac shaft. It may be brought bacl B. to Rhode Island for underground ser y vice. Rhode Islands Kearsage lod' e cores did not reveal copper vaiuei s considered worthy of development. Il n the LaSalle to the north, develops y good ground with depth Rhode Is d land may be encouraged to open shaft. 'e on the lode, but not otherwise.
 Electric hoisting will be given { at tryout at Winona No. shaft and D. King Philip No. 1 shaft, where thu sr equipment win be in service by May IT, The present hoisting drums will b' 10 left in place and the electric motor of geared to them. Each motor will havi h nominal capacity of hoisting iron is depth of 1500 feet, but it Is believed of 2000 feet can be reached. King Philil
