iary purposes. The charge cars and bullion cars at the smelter are oper- ated by electricity as well as the crane and conyerte-s. In fact, all power dis tribution is by electricity. Motors Of 40 volt induction are used
 The ore will be handled from the mines in steel bottom dump cars oi 100000 pounls capacity, which will run directly over the storage bins at the smelter, these bins having a cap acity of 4000 tons and ample provision for extension. The sampling mill, steel sampling floors, etc., are on the line of tae spur track leading to the ore bins. The ore bins are provided with weigh hopers, which empty in the charge cars, each of a capacity of 3S cubic feet. These are handled in trains by motor directly to the feed floor of the smelter and dumped directly into the furnace.
 Elliptical settlers will be provided between furnaces so each furnace will have an alternate settler in the event difficulty. The slag overfiows from the settler into 10-ton slag trucks on standard gage tracks, the tracks be- ing handled to the dump by a small locomotive and dumped by compressed air cylinders. Two stands of S4xl26 inch electrically turned converters with cast steel heads. are provided, the matte being handled from the set tiers to the converters in steel ket- ties by 50-ton crane having a 45- foot span. The converter hoods have an independent stack and dust cham Der and three extra shells are pro vided for each converter standa A dust chamber of $50 square feet, cross section by 100 Feet length is provided. The main stack connecting with the dust chamber is 12 feet in diameter by 175 feet high. The initial boiler plant consists of four Morrison internal cor rugated furnace boilers of marine type 10 1-2 feet in diameter by IS feet length Of 1ue, built for l6O pounds pressure and equipped for puIuIns crude oil, but with the necessary coal grates in the event of a shortage of oil.
 The power house, which is covered from end to end by travelling crane, contains one 11-inch and 22x36-inch Nordberg Corliss condensing engine direct connected to a No. Corners
 
 coompound, Corliss, condensine blow ing engine, having a 15-inch and 30- inch steam cylinders with two 36-inch iair cylinders and 42inch stroke. The electrical power has been referred to and does not require more detailed mention. The sampling mill, it may be mentioned, is fully equipped in every way. Tae smelter and converter building, as well as the power and boiler houses, are of steel construc- tion throughout. There is also a ware house, machine shop, and a building Tor sheet metal and blacksmith shop, dwelling houses, boarding houses, off cers quarters, company store building and numerous other small structures. The plant as it stands today cost ap- proximately hall million dollars, An abundant water supply has been pro- ylded by sinking a well in the Santa Cruz valley at a distance of a little over two miles, connection being made with an eight inch pipe line.
 In the beginning of this article men. ton was made of the foresight and confidence of the capitalists behind this big chain fo developing companies. WOTkeu out very largely by E. B. Gage and ". F. Staunton, the former well known financier and the head of the respect. i've companies. The latter is a skilled mining enginer and mining expert as well as a practical man in solving the numberless questions of detail in large mining enterprises and in the employ. ment of men to good advantage. As general manager he has proved a most valuable man. But going still further back, the sinews of war were fur nlshed by the Development Company of America" which has initiated many large undertakings in Arizona and of which F. NJ. Murphy of Prescott is the president.
 The Imperial companies are but a single group of large family of large companies that have been fostered and developed by the Development Com pany of America. It is due to Messrs. Gage and Staunton also to state that they hold similar relations to some of these other companies being success fully handled by their genius and fore sight Among the other large enter prises of the evelopment Company of America are the Consolidated Mines Co. of Tombstone, which in some re- spects is an undertaking of greater moment than the Imperial plans. An other is the Congress mine and still another is the Poland mine and tun- nel in Yavapai county, each of them being of sufficient magnitude to dem onstrate the capability and talents of the men connected with their manage ment.
