 A Waterless Desert.
 The country from Gila to Ajo has been a waterless desert except for a l00-foot well ten miles from Ajo, owned by Thomas Childs, and called Ten-mile well. No great supply is de- yeloped here, however. Western Pima county is a country of deep wells. Since the Ajo development was start sd and the construction of the railroad was begun, three wells have been put down. One of these, on the rail- road line a little over half way, is GAO feet deep Three miles west of the railroad an auxiliary we'll was put down and good supply was en- countered at 460 feet This will be piped to the railroad line
 Alo's Water Supply.
 "Aio's water supply has been devel- oped in a big wash which rises in the Big Ajos, miles to the south and drains a large territory. The Childs well was sunk in this wash at a point seven miles north of the mine This well is 1.2OO feet deep and an ade- quate supply has been developed. A double compartment shaft has been sunk Go the water level, a depth of GAO feet. where a chamber 40X2Ox14 has been blasted out and a big pump 100 tons has been installed to lift the water to the surface, from whence it will be carried in a ten inch pipe line to Ajo. seven miles away, another raise of 500 feet. There is a big power plant at the well and the power developed by oil-burning engines here is carried to Ajo over a pole line Water is now being haul ed from this well to Ajo. Eventually this power plant will be moved to Ajo and the power carried over the same pole line back to the well to operate the pumps.
 The Mines at Ajo.
 "The New CorneHa property is a mammoth low grade disseminated cop per proposition. Two entire noun tains are to be blown away. gradually, attacked by steam shoyels and treated for the copper which averages from one and a half to two per cent. The hills are nav being blasted down and the ore sent to the crusher, but in another six months, the steam shovels win be at work and the two mountains will begin to precepubly disappear The prospecting stage is not over, however. for the New Cornelia is still diamond drills to disclose the ore bodies.
 The Reduction works.
 They are making elecTolytic cop per at Ajo. It is the real stuff and not copper matte. l saw large sheets of it about four feet square, weighing POO pounds each piled near the mill, waiting for the coming of the railroad to be shipped out It looks good to the stockholders who can see they are taking something out, even if il is only on a small scale until the big new mill is constructed. The compa- ny started with a ten ton experimental mill which was increased to forty tons and is now being operated sue cessfully. It is located right at one of the copper mountains which will eventually be blasted away As this mill is located on an ore body it will later be removed. It is only one per cent in capacity of the 4,OOO-ton mill which will be erected on a flat about a mile northeast of the mines. A well is now being sunk on the site of the new mill to provide water for mixine the concrete from which it will be 
 The Reduction Process.
 "The New Comelia is working out
 anew process for reducing their low grade ores. After the ore is crushed, it is delivered by conyeyors to large vats. A three per cent sulphuric acid solution is then forced into lte gats from the bottom with centrifugal pumps. This solution separates the carbon from the copper in Che carbon ate ores and forms a solution of sul. phate of copper This process is re- peated until all of the copper is in solution. The sulphate of copper solu- ton is then pumped into other yats into which are suspended large sheets of copper four feet square, weighing about ten pounds, and sheets of lead forming the poles of battery These poles are charged with electricity and the copper in the copper culphate is deposited on the copper plates which are removed with crane when they nave increased in weight to 200 ponds The sulphuric acid in the solution is saved and used over again
