 Tombstone Consolidated Mines com pany continues uninterruptedly. The pumping record exceeds $500, 900 gal Ions daily and the water in the lower levels is kept clear of workings suf- ficiently to permit operations with out hindrance. The upraise on the l000-feet level for air connections is within few feet of connections with the s0O-fo level. The work on the Contention dike is being crowded night and day, and the north and south drifts run on this lead 1000 feet below the surface.

 It is announced in Boston that the Arizona -Cananea Mines corporation has taken over the Boston Miami Copper company, whose property ad- joins the Live Oak property. The Boston Miami and the interests con- trolling the Montezuma claims, which are included in the merger, are to re- ceive S1,OO0,0OO of the capital stock ot the Arizona-Cananea. At the Superior & Boston mine the sinking of the McGraw shaft has been re- sumed. The previous depth of the shaft was S47 feet. It has become known in connection with the strike instituted by the employees of the National Mining Exploration com pany, when the monthly pay checks did not arrive from the east, that N. L. Amster, president of the Arizona Commercial Copper company, has been holding the compauy's note for S100,0 ,00O, secured by mortgage bonds on the National property. It seems not unlikely. therefore, that MT. Amster will secure control of the National claims which lie between the two groups of claims owned by the Arizona Commercial company. Although the Miami Copper com pany is now experiencing a lull in mining development, it is the result merely of having made such a pro- gress in the past that very little more work remains to be done before production is begun. The work of completing the coucentrator and the auxiliary power house is being rushed to the end that treatment of ore nay be commenced by January l.

 The Scotch directors of the Arizona Copper company are said to have at last decided that the compauy's me- chanical equipment is not all that it should be and have concluded to cut down their dividends to secure better and more economical production facilities. Ne. 6 conceptrator is to be enlarged, new shaft or so will be permitted and plans are even being preached for a new smelting plant. Four drill holes put down by the Ari- zona Copper company from the 7th l level to explore the ground at great CT depth are reported to have cut copper bearing lodes. One of the drills entered the Blackhawk lode a little below the 900. foot level, where the vein is said to show 10 feet in width of high-grade ore. The drill also disclosed the fact that this lode is faulted, as otherwise it would have been encountered about 100 feet higher up.

 At the Gold Road two more Chilean mills and another compressor are nearly in place, but will not be put into commission until more power can be developed at the Kingman plant. Concrete foundations for an other unit. doubling the present capacity ot the latter, have already been completed and the work of erection will be rushed. With the use of the new Chileans and by changing from sand teaching to direct shining and ltration, the Gold Road mill is expected to treat 300 tons daily.
