EMINENT ENGINEER 7 PLEASED WITH MIAMI U. Parker Channing Talks 0p- timistically of the Future
 of Property

GLOBE June 5.-Work which has been carried on the property Of the Miami Copper company since the be- ginning of the first shaft there, has developed I3, 300 900 tons of ore, ac- cording 10 a statement made to the Silver Belt yesterday by ,. Parke Charming, vice president of ihe com pany and one of the -nost prominent mi..ing enSin ,ers of tine country. who has been in Globe for the past sey- eral days. liolling over the property.
 At the present time. while not great deal of development wir kis be- ing carried on. quite a good stzed force of men is at work jn the i70 and 510 foot levels.
 Blocking Out Ore. The major portion of the under ground work now in progress consists of blocking out the ore above the 31O foot level. preparatory to mining. As the sluicing system is 10 be used. considerable amount of preliminary work is necessary. before the actual work of removing the ore can be com menced.
 The showing made by drift on the 570 feet level is very encouraging, showing concentrating ore running very nearly 3 per cent This is much better ore than was expected on this level.
 , Will Sink to 600 Level. From the No. 1 shaft the main skel- eton has been cut out on the 420 or main extraction level The main long cross-cut has been started toward No. from the mine shaft and work is progressing satisfactorily. f -I,f inh fes d.Nx.- fn the 420 level, will be sunk withou. stopping to a depth of 600 feet. Work | will then be commenced or a crosscut. to connect with that on the 420 foot l level of No. 1 shaft.
 Grading on the new mill site is progressing rapidly, but actual con struction work will not be commenced | until the new Miami extension of the | Gia Valley railroad has been com | pleted, and construction of the rein forced concrete foundations. | Structural Steel Ordered. | The structural steel for the big
 plant and a good portion of the ma | chinery has already been ordered. It will be on hand by the time it is wanted.
 | While a mill of only 2000-ton ca | pacity is to be erected at the present time. the foundations will be amply large for a 3000-ton plant, should 1t be | found necessary to later increase the capacity. Rollers tables and other | machinTy for the mill will be only 1000 tons capacity at the start. They will be used for a run Of six months so that if any alterations are found necessary, they can be made when the second lot of machinery is in stalled The mine will start with al output Of 1000 tons daily and be worked up to double that amount al
 the end of six months, according tC present plans.
 Steam Power Plant.
 i The big steam power plant will con sist of three volt alternating current
 generators. driven by three Nordbere
 four-cylinder triple expansion engines land also Nordberg four cylinder tri
 pc expansion two-stage air compress
 or. with capacity of 10000 cubic feet
 of air per minute.
 Electricity will be used fir lighting
 and for power in the mill, shops ana for underground hauling.
 The compressed air will be used moi
 only to drive underground drills bur
 to operate the main hoist. an innova
 ton in this part of the country.
 As compressed air has a tendency
 to freeze up an engine. when used as
 a motive power, it will be heated witf
 oil, thereby producing very high ef
 fciency, at minimum of expense
 This plan will also permit the us' of one boiler plant for both the mi
 and the mine.
 Wright Promoted. . Louie A. Wright, general manage of the Miami Copper company. ha
