mechanical englneer for the Calumet

 company, is in the cast securing in dry pumping engines. With MT John c. Greenway, general manager Of the mines, he was in Chicago
 Friday and Saturday interyi (wing pump men of prominence and electri

 These electric pumps are to be placed at the Junction shaft, because this point is to be the deepest in the camp and the water will naturally come to this station. At the present time there are two sets of pumps. one
 Ocated at the bottom the other at the 9O0-foot station. It is figured that one plant at the bottom of the mine, this to be driven by an electric motor directly attached to the engine will be great improvement and will effect a substantial reduction in the cost of pumping.
 The electric pumps will also greatly lesen the heat in the shaft as compared with the present steam driven engines. In the bottom of the nine the level is very warm, the steam pipes assisting in increasing the temperature.
 The new pumps will have a capac ity for 2.000 feet in single lift. The management Is anticipating pumping from much greater depths than the present 1.500-foot station, which is now the bottom of the mines active operations. The indications point to a very thick ore deposit at this shaft
 Even with its restricted output paying a pretty good price for smelt ing ores and selling its copper for a very low figure. Superior & Pitts burg is making money. It would show a splendid earning if it produc ed to its capacity and could obtat.i fair price for It's metal
 While we do not know the exact cost for making it's pounds of copper at the present writing we are sure 1t viii compare favorably with the best mines in the country. and know it can compete with any Of them for a market if it is to be a fight for it which would be unfortunate. Costs have been steadily reduced and MT Greenway will have them consider. ably lower as he is hot after every item entering into the business. He has already made new marks for the company since taking hold, we are reliably informed, and he hasn't fairly started as yet
 In a conversation with Mir. Chas Briggs president of these companies who has just returned from Bisbee he informed Iron Ore that he wa very much gra.ified at the way the properties Calumet G Arizona and Superior & Pittsburg were Ioox ing. and be was certain that when business reached its normal propor tons again that the companies would prove satisfactory to all inter ested in them
 MT. Greenway, knowing what had been done in the way of finding ores in levels that had been supposedly pretty well worked out has iraugu- rated system of upraises for the better searching if the ground. Levels being 100 feet apart. there is coasid. erable chance for the missing of rich punches of ground Under the old plan upraises were made two sets wide and were pretty expensive to timber. timber being high in that section. Now raises are made much smaller when being put in for ex pioratory purposes and they are un- timbered for the greater part Should ore be discovered they are made larger and mbered nhe sulphide ground stands very we'll. The oxides of the upper levels were not so easy to hold up. being moist and heavy generally. Tine system of searching the ground will well repay the ex- pense, as frequent punches very rich in copper are met with These arc offshoots from the main deposits. pockets in the limestone
 It is the history O. the Bonanza Circle properties that the gold and silver have generally been found :n the sulphide ores, these zones Scing much more prolific in these n'hsr als than the oxides. The treatment of the sulphide ores in times when copper is low and gold and .i:vor selling at fair prices seems n Ire the right practice and Mir Gssa,.- way is devoting considerable atten- ton to the sulphide areas at this particular time
 Superior & Piusburg mines have accomplished al in the way of ore development that was claimed Cor them. Considering the amount of underground opening they have fully come up to the expectations of the management Much has been done in the way of long drifts to connect the several shafts, which was work calculated to make the labor s-fe and to permit labor accomplishments by providing the best possible ven- f;lafiOp rThie fe a hot cotr,trr- fys
