Thus it haE been deyc- oped that here is a great steam sh0vei proposition, ore to bc loaded into cars and switched to the treating pIanfr
 First it was determined that tha orc body was SO vast that it would make the undertaking a success if a method of treatment could be found to sunici- ently lessen to the cost of production The company did not jump into a rau- road building at once. Nothing Of the kind was undertaken until it was dem onstrated that a satisfactory method of ore treatment had been found Then steps for the building of the road were taken, and now that railroad is rap idly approaching completion
 Build Model Town.
 In connection with the plans of the company is the project of making the new town which will be built for the mine and it's works a truly model town. Captain Greenway has had ex- Iperience in town building in the North. before he came to Arizona Copper fields and from that experience and from his studies in sociology and city and town building has developed ideas on what a model town should be These ideas will be embodied in the laying out and the building of the new town. One feature will be the central plaza surrounded by buildings of the mission style of architecture and the most attractive type. After the open ing of the railroad the first of next year, town building can be commenced and carried on at the same time and ] in connection with the other construc- tion work
 Water is Developed
 During the year 1914 water devel- opment was one of the matters seri-
 ously undertaken by the company. boilers and air composers were fn- stalled and a high pressure test made on the water strata encountered in Well No l. This test was continued for IT days and nights consecutively on an average of 197 gallons a minute for the entire period with out lowering the water level This was sufficient encouragement to warrant the sinking
 of shaft for permanent pumping plant A shaft was located 100 feet south of the first well and a two com pertinent shaft was completed in No vember to the water level. 646 feet. A station was cut out for the installa- ton of a 800 gallon pump.
 Another well was put down in the broad valley some 13 miles northwest of the mine. Water strata was met at AGA feet and such strata continued | to a dept of 600 feet The well was continued to a depth of 665 feet when it was determined that sufficient water | had been developed. It is believed that that sufficient water has been de- veloped in these two wells for all pur- poses and that sufficient can be ob- tained from No. 1 well alone for all purposes in connection with a 4.O0O ton day teaching plant
 Determine on Treatment The 1913 annual report showed the development of 11,954,0O tons of car bonate ores to be leached At that time it was stated that experimenting on a different method was preceding.
 After extensive laboratory work in Douglas a substantial crushing plant
 was installed at Aio in connection with a one-ton plant to further develop the process in the field. The tests proved eminently successful and forty-ton plant was erected in which future changes were noted and re- suits were even improved. Any fu- ture changes in methods will be mere matters of detail
 Railroad Opens District
 In the Ajo mountains are to be found some of the oldest workings in the entire state but like all such work ings of the early days these were for the purpose of extracting high grade ores, especially of the precious metals It remained for the New Cornelia Copper Company to undertake the mining of the lower grades of a baser method, to evolve new and improved methods which would make this pos sible and by the building of a railroad to open up for the first time. this old district and to make possible its de- velopment as nothing else could. The railroad means not only possible pro- duction for the New Cornella but it means ore transportation for other properties that could not be worked when a long desert haul by wagon had tO bp made
