plOratlOn IS pushed along the under ground and the ore made ready for eXoncmica extraction in large volume, the mill capacity will go up.
 Runs Like a Watch
 Vast and complex as is Inspiration mining and milling practice, it runs as smoothly from the lowest under ground level of the mine to the last step in the milling process. as a watch. From it's power plant, rated as of as high efficiency as any in the country producing electric current through the employment of stream, straight through mine, hoisting plants and mill, there is no lost motion, no waste, no over looking of efficiency. Skips load the ore automatically in the feed bins, which automatically in the surface bins, which automatically feed to the belt conveyors carrying the material into the mill, from whence to the de- livery to settling tanks and thence to the cars to smelter is all automatic. timed everywhere to the second and with unfailing provision at every step against variation from calculation.
 NO Out m WOTH TOrCe
 In the mine there is no less employ ment of the most advanced practices and appliances in getting to the oIe. bodies and extracting these. It is by reason of these things, of highest ef- ficiency in every branch of every. de- partment, that Inspiration and the oth- CT great mines of Arizona, through con- stant research and endeavor carried on at tremendous aggregate cost in the course of each year, keep their costs going down and their ability to handle larger tOnnages and lower grade ores going up. There is the secret of their ability to constantly increase the en- plOyment of labor, notwithstanding the constant increase in the employment Of automatic machinery, for they are enabled to earn more money and open more ground. AS the ground is opened there is the economical need of ex- tracing it's values as quickly as. 1ossi- ble, and attending this is the need of more capacity. more labor and more general expenditure of money. It is an endless chain upon which travels the constant requirement. for bigger and bigger expenditures and greater and greater effort.
 Mining Supports 100000
 The more than 100000 population contained in the strictly mining and smelling cities of Arizona, the many million dollars contained in their banks, the millions of dollars they are spending at the immediate tima in new business blocks and residence construction, and for municipal .m- provements, find explanation in this glimpse at the great work being car ried on by the copper producing rl,nes the lead, silver, gold, zinc and other metal producing enterprises. These cities include Bisbee with 10000 pop ulation. the largest center in the state Douglas with upwards of 15,000, Ray and it's environs with 1000, Globe and Miami with upwards of 15, 5,000, Ajo with 5000, Jerome and Clarkdale with 12,000, Oatman 2,5O0, Kingman, 5000, Chloride, 2.000 Then there are Hum boldt, Sasco, Silver Bell, Salome, Wenden. Mayer, Superior and a num- Der of other strictly mining towns with an aggregate of probably 10000 more population. In all of the larger of these cities are public improvements, schools. churches. power an1 light plants, sewage, hospitals second to none, railroads and good ;'oads con nections-conditions indeed that af- ford to residents the advantages of ad- vanced city life
 Treat One Per Cent Ore
 In the bringing about of successful treatment, which means profitable handling of low grade ores is the most interesting and important phase of re- cent and present work in the state, and it is said that in this it is leading all others, as 1t is in tonnage of copper production. At Clifton the Shannon management has accomplished very much of general benefit in finding the way t. successfully treat taiings with new copper content of around one per cent
 At Ray, the Ray Consolidated man. agement is bringing to completion the working out of intricate problems which it has had to solve, and which have compelled the employment of much time, patience and deep study, for all of which there is ample reward near at hand for everybody concerned
