Lake Superior and Arizona.

Ac l<dhC SupCAlOA S <allLVAd ing company is another development company composed principally of Michigan capitalists, and organized after the formula usually followed in the Warren district. In speaking of the progress of that company in the Globe district the Belt says:
 Supt. A C. Sieboth, of the Lake Superior & Arizona Mining company, has been at the mine for the past ten days receiving and having installed the large air compressor, the founda- tions Tor which have been ready for some time. The progress of work at the mine has been retarded by lack of compressed air, and consequently, no time will be lost in getting the mach inery in place to supply the need. Considerable difficulty has been ex- perienced in getting teams to haul machinery and supplies to Superior, owing to railroad construction and work at Tonto damsite, which has created an unusual demand for teams.
 According to advices received at the eastern office, the Lake Superior & Arizona is sinking in it's shaft at present, having made about 35 feet SiACS EtSuuluS. utIS IS NOncluSl dUAc
 VII e V -wag W bgy, < wfix km water coming in, but not so much as was feared, and it is hoped sinking operations can continue without inter- ruption. Samples have been forward ed to the Calumet office showing the nature of the ore which is being de veloped One of these is an oxidized iron ore which came from the vein that is encountered in the drift run ming south from the shaft.
 A second specimen was taken from about the center of the copper ore body in the Anderson tunnel This specimen shows a cubial crystaliza- ton of an iron oxide ore. As iron pyrite or sulphide crystalizes in the cubical form the rational deduction is that the material was originally an iron sulphide with some copper en- richment A third specimen, taken from the contact lime rock in the drift north from the shaft shows a typical sulphide character. In the first level drift north from the shaft, unaltered sulphides have been found. Lately there have been indications of suIphides in the drift south from the shaft also.
 The stope in the Anderson tunnel reveals a much larger body of ore than Superintendent Sieboth had dared to estimate. Recent work in stoping shows a body of high grade ore some IS feet in width, with like ly chance that even this width may increase as the extraction goes on. In operating this stope, from which shipments are being made, the man. agementr in endeavoring to secure a grade or ore which will be profitable without anything more than the most casual sorting at the mine.
 . It is the intention of the company to remove its western office from Globe to Florence in September, if present plans materalize. This will be quite an improvement in the ac commodations of the company, since Florence has become the railroad destination of Lake Superior 6 Ari zona shipments, now that the Phoe nix & Eastern railroad is built 1T there. The clerk in charge of tho Florence office will then be able tc look after the company's interest ir the way of transportation.
 Several carloads of ore from tho Superior mine have been delivered al the Florence depot for shipment tc Denver, Colorado, where the ore vii be stored at the ore testing works til Manager Sieboth. of the Superio company, is ready to go there ant conduct a series of tests to determine the most economical and eficien -,,otb1d of troarino fha 0rpc af rhf mine on large scale, and to also de termine the character and capacit! of the machinery required to success
