 the EIeven-Hundred Feet Level.
 The advent of the diamond drill Will, within q comparatively short time, en- firely change the method heretofore employed in determining the value of soinerai lands in the Warren district Already several of the more promi- hent prospecting companies have de- eided 70 employ the Crill method of further exploiting their lands, and as crtlers for the machines have been placed some time ago, 1t will be but few weeks ere a vast amount of work Hill be done in the various sections or the Bisbee camp.
 That the results will prove satisfac- tpry. insofar as finding out the value of the many properties is concerned, there is no doubt. Extensive use has already been made of the diamond Grill on tine Junction conpany's lands, and the work has been carried on with great success. Conditions here, so far as general formation is concerned, fs similar to those in most all parts Sf the district, so the assumption that drills will be used with equal success fn the other sections of the camp is not outside of reason. At least, it is fair to assume that even should cer- tain companies, who have decided to do exploratory work along this line, encounter some difficulties not met with at the Junction, they will still gave much money by exploring by means of drill holes in preference to shafts and drifting.
 Economy has at last become the Waichword in the Warren district, where previously vast sums of money have been expended in developing properties. Deep shafts and tunnels have been sunk at great cost where fhe use of a diamond drill would have Reen just as satisfactory in locating are bodies In many instances thou sands of dollars could have been saved and it is a strange fact that the men who have been prominent in the devel- cpment of this rich territory have not long ago realized, in the drill method, zn economic measure of vast import ance It is not unreasonable to pre- dict that had many prospecting con- panies adopted this method in proving heir lands, there would now be con afderably larger number of success fully operating mines in Arizona to- day. Thousands of dollars expended in sinking shafts and running tunnels would have been saved to later be Used in the work of opening up ore deposits and in the purchase of equip Inent for bringing the minerals to the surface.
 But it is not yet too late, as there are numerous properties whose value for mining have as yet been undeter- mined. Many of these warrant the Expenditure of money in this direction, and the diamond drill method has been demonstrated as the most economical. That the machine will be used exten- dvely in the future is certain, and as 4 result at least some of the properties vill be so situated, at a much earlier date, to rroduce mineral than they Nould have been under the old method of exploitation.
 Drill Work at Junction.
 At the Junction, where the first diamond drill work was done in the Warren district, Superintendent Louis Buese, one of the Sullivan Machinery sDmpany's experts, yesterday com pfeted the erection of the machine for fhe sinking of the fourth hole on this property Drilling will be commenced (Oday, and the company will, in addi- 6on to this work, continue prospecting with the drill until the value of every xect'on Of its considerably large tract of land is. proven.
 Superintendent Buese said yester- day to The Review representative that since starting exploratory work one Hbe Junction some six months ago with fhe drill, no difficulties of a serious neture were experienced. The three Eples put down were sunk in a reason aa,Ie length of time, and results were ea'te satisfactory. The theory ad- unced, when it was first proposed td use CfJUS III tnlS Stct1oif, tudl LuS Aua- chimes were not adapted to the forma- ton here, has been absolutely dis rroven While in some places cav fties and openings of various natures were encountered, they did not inter- fere materially in the work of sinking and finding out just what sort of min eraI or other matted was deposited be- Beafh.
 C. & A. to Use Drill in Shaft.
 Today drill will be put in commis- sion in the Calumet & Arizona's shaft al the 1.100-foot level, for the purpose q exploring the ground in this vicin- Hy. Further diamond drill work at 6is prooer'y has also been mapped snt. These facts are assurance that results attained at the Junction, so far
