 Shipping
RAILROAD TO M'GAW
 SHAFT COMPLETED
Probert Here This Week and Will Make Plans
 For Future

A force of over 100 men is employed in underground and surface work on the Superior & Boston property, locat. ed in the Copper Hill district, four and half miles east of Globe. The com pany is now directing its energies to- ward putting the mine in a position to ship ore proftably. The 200-ton bins recently constructed just north of the MeGaw shaft have been filled with ore, and the dump is now receiving much of the ore taken from the mine in the course of development. The pump sta tion on the 600-foot level of the Me Claw shaft was finished the first of last week and has been timbered through. out. A force of men is now engaged in finishing the station north and south of the shaft on that level. This station extends for twenty-five feet north and south from the shaft. The large pump station on the sixth level is east of the shaft. This station is fifty-two feet long and is being most substantially timbered The crosseut connection be- tween the McGaw shaft and the Great Eastern workings of the Superior & Boston mine was made last week and the connection of the Superior & BOs. ton Copper eompany's Great Eastern drift with one of the main drifts driven east from the Eureka shaft of the Arizona Commercial mine is practically completed This G00-foot level eonnec- tion will afford better ventilation for both mines.
 
 The railroad leading from the Ari- zona Commercial to the McGaw shaft on the Superior < Boston property has been finished, so that shipments of ore from the McGaw to the smelter can be made at any time when the manage. ment desires to begin production. The date for commencing shipments has not yet been set.
 At present, two raises are being put up on the Great Eastern ore body from the 600-foot level. One of these raises is located in the Great Eastern drift. seventy-tive feet west of the Great Eastern winze and the other one is 100 feet east of the Great Eastern winze. These raises will connect with the intermediate level, ninety feet above the 600-foot level The manage. ment of the Superior 6 Boston Cop per company is now making prepara- tions to resume sinking the Great East ern winze. This winze now extends thirty feet below the sixth level and goes down in ore with the vein.
 The sinking of the McGaw shaft has also been continued. The bottom of this shaft is now about fifteen feet below the sixth level and sinking will continue to the 35-foot point, which will probably be reached by the middle of this week. Work on the crOsscut to form the sump of the pump station on the 600foot level will then be begun. This crosscut for the stump is now about ten feet long and, when complet- ed, will have a capacity of 30,000 gal Ions. Work on the stump of the McGaw shaft is being continued before driving the crosscut for the pump station stump. In order that the concrete forming the foundation for the pump may not be broken by the blasting, the installation of a Prescott pump on this level will be commenced about February 15. The capacity of this pump is 1000 gallons. The water column for the McGaw shaft is now on the way to Globe. Two 25O horsepower Stirling boilers, also, are expected to arrive at the mine in short time. These boilers will be added to the present boiler plant at the McGaw shaft.
 The long drift being driven west from the Gardner shaft on the 400Lfoot level has run out of limestone into dia- base. With about 100 feet more of driving, this drift will reach point directly under the Black Oxide winze. The drift driven west from the Great Eastern workings has reached the prop erty line.
 In comparatively short time, the Superior & Boston mine will doubtless begin production. While it has not yet been decided just what the daily shipments will amount to, it is certain that not less than fifty tons day will be sent to the shelter. Frank H. Pro bert, consulting engineer for the Su- perior & Boston Copper company, is ex- pected daily and during his stay in Globe some definite plans will prob ably be made for the future conduct of the work at tho mine.
