Some Big Work Under Way.

IerenJ nlnlng companies III tne Citltou' Morenci district are getting in fine shape for the increase in the price of copper.
 The new brick flue dust chamber of the Detroit Copper Mining company is almost completed. A new crude oil burning boiler be,ng added to the pow CT house, and many other improve ments in contemplation will bring the company up to more uptodate ways of handling the product.
 The new addition to No. 6 concentra- tor, having been fully tested, is run ning regularly and nicely, and this and the added Improvements in the mlne departments of the Arizona Cop per company limited are bringing the mine departments of this company in- to the first rank.
 The tunnel from the Humbolt mine to point just above the concentrator, where all the ore is hauled under ground, the motive powor being cleo tric motors, and where all the hoisting is done has been in operation now for some time and has proved success, having shown decrease in the cost of handling from mine to mill.
 The tunnel being run through from Metcalf, to form a junction with the Humboldt tunnel is now well under way and will allow the handling of the Metcalf and Coronado ores here. This will call for the doubling of the pres ent milling facilities here and the de- cisiOns of the courts prohibiting the tailinys going into the San Francisco river at Clifton, will necessiJa,e the closing of the old concentrates there and leave Morenci the chief mining and milling town in the district.
 A tunnel is also being driven from the Longfellow incline through the lime hill where the Arizona Copper company, now gets it's lime, and on from there to point near the site of the machine shop, which will lessen the expense of hauling the concen- trates and materials to and from the concentrating plant. also relieve some of the mi 'e and dangers around the store departments and hotel.
 Dr.. l. D. Ricketts, consulting en- gineer of the company. in company with general manager Carmichael. was here looking over the present wol k- ings and arranging new plans for i'm provements, with the view of modern. izing every department connected with mining and treating the ores. A new shelter having been definitely decided upon. it will be necessary, of course. to 'ov de ample milling ia a,iities fIr the handling of the great stores of ore now blocked out and in reserve, which will run the treating plants for years to come.
 the Copper plate group, was in town this week talking over plans of de velopment on these properties, which lie to the south of the Coronado noun tain. The company now has a tunnel running along the vein for distance of 500 feet. bringing a depth of about 300 feet. The workmen have develop, ed some low grade ore, but in running a straight tunnel, have left the ore body, and gone on with the develop. ment work.
 William Mccoy, superintendent of the Eagle Gold and Copper Develop ment company, has about l5 men al work on it's property, expecting to de velop enough ore to ran the mill or the property built by former operator. and owners. This property, like many other small ones, has had varied and checkered career, but those who have known the property for any length o time have never lost confidence in it. as it was proved that ore of paying quality was to be had, but unfortunate ly the former owners the Gold Bel, DtNclopulout anu NeuuCtiou COtn pan J had only began to get into good development way when the panic ot 1907 struck the country. They never were able to rally sufficiently to over. come the shock. Recently new com. pany was formed, and they hope not only to pick up the work where it was left off, but to carry 1t to successful conclusion. The present owners claim to have backing sufficient to give the
