Arizona republican., 1917-05-06

explains the great prosperity which
 abounds everywhere fin Arizona and
 which is unprecedented in it's annals to
 any such general extent as now pre-
 vails The cotton acreage brought in
 during the last few years and some
 gain in the agricultural area helps, but
 these factors are negligible in looking
 the state over as whole in comparison
 with the enormous gain that metal mining has brought about and which in fact has made the necessary money available for the development of the lands of the state. To such money the mining industry is adding constantly and without stint. Those who would farm can get money in plenty from the mining community banks, which have always loaned freely of their funds to ! the farmers even when the latter could not get money from their own banks. Nor have the banks of the mining centers ever lost money on their farm loans.
 The managements of the big copper producing mines of Arizona have made
 wonderful advance in both the mining and metllurgical divisions in the last several years, and they are still at it. It may be that they will not accomplish 1 as much in the next year or two as they
 have since 1914. but they are never theless going to accomplish great 1 deal. That much is now assured In the laboratory of no single producer op- erating reduction plants in the state 1 IS there idfeness. From top to bottom
 the staffs of these organizations are striving for more efficiency. more re-
 covery of values, the utilization of more
 material. All of them are succeeding; i all are bringing forward new ideas, new 1 applications which are receiving test in practice. Copper Queen, C. X A., Shan
 non, Ray Arizona Copper, Detroit Cop ] per. Old Dominion, Miami, Arizona Commercial, Magma. United Verde and i of course United Verde Extension. are
 all at it.
 1 Even Inspiration is busy although it
 has today mine and mill equipment and
 operating methods Which are conceded to be the very height of scientific and mechanical attainment to thi stime The mins is daily sending more than l l9,VO0 tons of ore to the surface. h. deed, with the eighteenth and nine teenth nuits of the great mill now in commission 300 tons of ore are being 1 handled daily, and as these new units
 of the mill are turned up they will bring
 the ore treatment capacity up to 10000 l tons the day. This is much more than l the rated capacity of the mill but it is do'hg the extra work easily. Twenty
 thousand tons of ore the day is about 1 all they care to handle from the mine l at this time, but the room has been i left Tor more units as desired and as i exploration is pushed along under ground and the ore made ready for l economical extraction in larger voI ume, the mill capacity will go up Vast and complex as is Inspiration mining and milling practice. it runs as smoothly from the lowest underground l ieNel ef the mine to the last step in the l Hlllllhg process, as watch. From it's l power plant, rated as of as high eff ! cheney as any in the country producing 1 electric current through the employ ment of steam, straight through mine
 holstlnS plants and m1II, there is no lost
 motion, no waste, no overlooking of ef-
 lIclehcy Sklps load the ore auto- ildtlcaily with no second lost, from au- l tomatically loaded bins and dunn the
 ore automatically in the surface bins | which automatically feed to the belt l cohNeyors carrying the material into
 the mlll, from whence the delivery to i settllnS tanks and thence to the cars | lo Sheltef Is all automatic timed ey- eryWhere to the second and with un-

 larger tonnages and lower grade ores gong up. Therein is the secret of their i dplllty to conStantl-- increase the em- i ployment of labor, notwithstanding the 1 constant increase in the endowment of 1 automatic machinery, for they are on ] abied to earn more money and omen more ground. As the ground is opened l there IS the economical need of ax- l tracing It's. values as quickly as nos
