The statistics indicate a gradual though not a constant increase 

 for the period given. As might be expected, the increase has not 

 been manifest in the low grade limonite and carbonate ores, but 

 has been due almost entirely to the growth of magnetite mining. 

 No carbonate ore has been worked during the last three years, 

 and the production of limonite is not important. 



Developments at Mineville. The Mineville ore bodies have been 

 exploited actively by the two companies operating in that locality 

 Witherbee, Sherman & Co. and the Port Henry Iron Ore Co. The 

 total shipments for 1904 amounted to over 400,000 tons, all high 

 grade magnetite. The deposits worked by the former company 

 are known as the Old Bed, New Bed and Harmony. The first is 

 very phosphatic, while the New Bed runs quite low in phosphorus 

 and the Harmony averages between the two extremes. The prin- 

 cipal openings are the Joker, Bonanza and A and B shafts, of 

 which the last two were recently sunk on the Harmony. The 

 Cook shaft lies some distance from the others, and the relations of 

 this ore body have not been definitely established. The operations 

 of the Port Henry Iron Ore Co. were confined, as heretofore, to Mine 

 21 on the Old Bed. 



The progressive policy of improvement in both underground and 

 surface installations adopted by Witherbee, Sherman & Co. has 

 had a very beneficial effect on the mining industry which will con- 

 tinue to be felt for a long time in the future. During the past 

 year attention has been directed specially to increasing the efficiency 

 of the various plants, rather than to adding further equipment- 

 The most extensive changes have been undertaken in the old mill, 

 and when completed it is hoped that the milling capacity will be 

 sufficient to handle the full quota of ore. The new mill has worked 

 very successfully. An improved Ball-Norton separator of the
