Superior & Boston Will Be gin Shipments Tomor-
 row Morning
FIFTY TONS PER
 DAY FOR STARTER
Ore Bins Filled and Every thing in Readiness for
 Continuous Run

Tomorrow morning the Superior < Boston mine will begin snlpping ore to the Arizona Commercial shelter The daily shipments wil at first aggregate Ho5 less than % tons. It is estimated that this ore will run about nine per cent copper.
 At present everything is in readiness tor the beginning of ore shipments. Preparations for actual production were completed several days ago, when the railroad from the Arizona-COmmec- ciaI shelter to the McGaw shaft of the Superior X Boston property was fn- ished and the connection between the McGaw and Great Eastern workings was effected by means of a crOsscut. The 200-tOn ore bins situated just north of the McGaw shaft were filled with ore preparatory to the beginning of produe- tion over week ago, and in the mean time much of the ore taken from the mine has been thrown upon the dump. shipments would have been made be- fore this had not the repairs on the wa ter jackets of the Arizona COmereial furnace necessitated a temporary shut down.
 Preparatory to continuing work on the pump station stump at the 600-foot level of the McGaw shaft, the sinking of the McGaw to depth of thirty-iiye feet below the sixth level is under way. As soon as the 35-fOOt point is reaehed sinking will be discontinued temporar fly and work on the crosscut which is to form the pump station stump at that level will be resumed. This pump sta ton stump will have a capacity of 3O,- 900 gallons of water and by means of it the pump foundation should be kept perfectly dry and firm. Two raises are being put up on the Great Eastern ore body from the sixth level drift. One of these raises, located about seventy-hve feet west of the Great Eastern winze, measures about thirty feet. The other winze, at a point about loo feet east of the Great Eastern winze, is up about twenty-five feet. Both these winzcs have been continually in ore running about nine per cent copper. It is expected by the management that they will con. tInue in ore until the intermediate level ninety feet above is reached.
 The sinking of the Great Eastern
 
 thirty feet below the sixth level. Drift ing westward toward the Black Oxide winze on the 400-fOOt level of the Gard ner shaft is progressing rapidly. The breast of this drift is now about sixty feet from the Black Oxide winze, with which it will ultimately make connec- tion. The ground through which this drift is being driven carries | great deal of manganese and considerable sill yer, and copper values should eventual ly be developed.
 Two 25O-horsepower Stirling boilers, which have been shipped to the mine, are expected to arrive soon. These boil CTS will be added to the present 5OO- horsepower boiler plant at the MeGaw shaft. The water column for the Me- Cav is also on the road. About Febru ary 18th, the installation of l,00o gal lon Prescott pump, capable of raising water from a depth of 1000 feet, will be installed on the 600-foot level of the McGaw shaft
 Altogether, the conditions at the Su perior & Boston mine are very favor able to the development of large ore reserves As the naturalization in that district is of the same general nature as at the Old Dominion mine and the fractures are cOntempOraneOus with those occurring on the Old Dominion property, there is ample reason for be- lieving that the best copper values of the Superior & Boston mine will event ually be developed on the levels below the sixth, which is the lowest level so far established COnsultinO Enpinpcr Frank H. Probert has been in Globe for several days on business connected with the mine. President Wm. c. Rice ar rived here last night.
