AlAu SEAQe DDUA oA ore III n raise which is now being put up from point near the end of the long west drive driven on the 300-foot level. The ore opened by this rise averages be tween 9 and II per cent copper. and because of its encouraging uniform high grade stoping has been com menced there
 Among the recen, encouraging de velopments at the Arizona Conner cial mine is the decrease in the daily flow of water handled by the pumps on the seventh lcvei from 3.O00O to 2.500.000 gallons. This decrease is considered fairly good evidence that the area between the sixth and seven h levels is being rapidly drained.
 Most of the ore which is being treated each day by the smelter is be ing mined on the 600-foot level but much ore is also being stopped on the fifth level. were a raise recently put up. is developing material of good commercial grade west of the Black Hawk shaft The shelter treats from 200 to 21O tons of ore daily, and by maintaining this rate of production. it is eslmated that the total output Of fine copper during the month of March will be little over 400,000 pounds
 Sinking will be resumed today at a depth of eco feet in the No. 4 shaft of the Miami Copper company. A ship ment of creOsoted timbers arrived at the proper,y recently and with this supply on hand, To further delay in sinking is anticipated. The final depth of TOO feet should be reached by the middle Of April.
 At the Superior & Boston mine. preparations are being made 10 install a small hoist at the winze put down from the 400-foot level of the Gard ner workings. at a point almost di- rectly under the Black Oxide winze The comparatively high grade ore struck in this winze at a depth Of fir cen feet. about a week ago. makes it necessary that the winze should be sunk indefinitely for exploratory pur- poses.The assay returns from the ore samples taken from the winze run about S.7 per cent copper
 Al meeting of the stockholders of the Bos. .on-Miami Copper company held in Boston. March g, the stock and property of the Boston Miami De velopment company was taken over by the new company and the following of fcers were elected: President. H. F. Fay; secretary and treasurer. C. J. Morrissey; H. F. Fay, Walter l. Eros $. George G. Endicott, James Gardner and c. J. Morissey directors.
 The management of the Inspiration Copper company will soon have sew eral air drills operating in the level work from the Joe Bush shaft at the Keystone Gulch tunnel The large compressor just ins. .alled at the latter location and capable of driving fifteen air drills. should be in commission in a very few days. as all Of the machin- cry for its operation has been installed and the preliminary trial of the boil CTS and engine is being made at the present time.
 At Joe Bush shaft workings four or !, five drills will be used 70 begin with and more will be added from time to time as they are required At present, ! the principal development of this part of the Inspiration property consists of raising from the 400-foot level to he eapping. CT upper limit of The ore body. according Co the formulated plan Of mining the ore developed.
 On the 25O-foot level of the Cac- |, tus mine an ore strike of considerable importance has just been made in 6 crosscut where two feet of maiachite. assaying abou. 50 Der cent. copper has just been passed through. This body Of ore is believed to be an extension of the high grade ore body encounter ed in sirlzfu inc ehoff -st a 1as.fh oF
