sASA' -
 As the result of the completion of the Miami extension of he Gila Valley railroad, the work of erecting the new 4000.ton aonce !, -a.or on th. property of the Miami Copper company has been taken up with reversed activity.
 The work of building the foundation for 2000-ton concentTator, the first half of the installation, began yester lay and the grading for the entire plant is practically completed. 4 part of the machinery has already been ordered and according to J. Parke Channing consulting engineer for the general Lewisohn interests, part of the ma- ehinery should be on the ground by tho first of the year.
 X 75-killowatt generating set will be installed at once to be used for running a concrete mixer, and to. furnish power for general construction work. A hoist, to be used in hauling material from the railroad spur to the millsite will also be put in place at once.
 It is planned to install lhe air com pressors ahead of the other machinery, when the eoncentrator construction is commenced, in order that. work Tn the mine may be carried on. IL IS the aim of the mine management; to have a good supply of ore on hand when the concentrator is finished, in order that re duetioR work may be commenced with out delay.
 Will Resume Well.
 The work of sinking well in the Pinal creek bed near Armey's place has ceased temporarily, owing 10 rnc rush of other work, but it vas stated by Mir. Charming yesterday that the company had no intention of abandon ing the water rights, however.
 A contract has been ente;ed into be. tween the Miami Copper company and the Old Dominion company, whereby the waste water from IT latter will be utilized at Miami.
 This contract is for the benefit of both mines. At the presen time the Old Dominion company is of the p.n- ion that much of the water pumped out of it's mine eventually finds it's vay back to the lower levels again. It is the plan of the Miami company to continue the Old Dominion Hume to it's well site and then pump the water tJ thc Miami workings. The well will also be da- veloped, in order that good suppiy of water may be obtained at all times.
 Development Work.
 Development work is progressing steadily in the mine, although the prin eipal work is that of sub drifting and raising as underground work is ham pered by the lack of compressed air. The work now in progress is mainly that of preparing the new 420-fnot ex- the ore will come, when the mine is opened up for the removal O. ore.
 At the 420 foot level of the main shaft, 1000-ton ore station is beiug cut, for use later on. This work is progressing steadily.
 A double drum-hoist has been secured and as this machine is now in the Gila Valley yards, it will be installed at the No. 4. shaft within short lime. With the machine in place, the work of sink ing this shaft to point 50 feel .below the 570.foot level, 100 feet deeper than at the present time, will be taken up.
 From the 570-foot level drift will be run to the ore body and new ex traction level opened up.
 Some new work is in progress on the 370, 470 and 570-foot levels, all of which is gradually enlarging the size of the ore body.

 Figuring the ore body at 4,0O0, 900 tons, the amount already blocked out, an extraction of 200O tons per day would give the mine life. of twenty years.
 The ore is holding up good aBl will average easily around 3-4 per cent, in the opinion of MT. Charming
 Little difficulty has been encountered in the matter of building material, as good rock quarry has been established on the property and an unlimited auan- tity of sand is also to be had The mine is furnishing sufficient water for use in the construction work.
 The draughting office, in charge of H. Kenyon Bnrch, is being removed to the mine, temporary quarters having been established in one of the new cot tages, which are being erected for the use of the mine officers.
 Mir. Charming will leave today for Ray After spending short time there he will go east, with the intention of returning about the first of the year.
