The list of companies that were active in the industry last year 

 included for the Adirondack region: Witherbee, Sherman & Co. 

 and the Port Henry Iron Ore Co., Mineville ; Cheever Iron Ore Co., 

 Port Henry; Chateaugay Ore & Iron Co., Lyon Mountain; Salis- 

 bury Steel & Iron Co., Salisbury Center; and the Benson Mining 

 Co., Benson Mines. The producers of magnetite in southeastern 

 New York were the Hudson Iron Co., Fort Montgomery, and the 

 Sterling Iron & Railway Co., Lakeville. The output of hematite 

 was made by C. H. Borst, Clinton; Furnaceville Iron Co., Ontario 

 Center; and Ontario Iron Ore Co., Ontario Center. 



Mineville. The product of the mines at Mineville, the most im- 

 portant center of the industry, was a little below that reported in 

 191 1, in actual figures 675,512 long tons against 734,353 long tons 

 in 191 1. Operations were conducted in the same mines as in the 

 preceding year, including the Old Bed, Harmony and Barton Hill 

 groups of Witherbee, Sherman & Co. and 21 and Welch shafts of 

 the Port Henry Iron Ore Co. 



The principal feature of the year's record of developments, per- 

 haps, has been the progress of underground and surface work on 

 the Barton Hill properties, as a result of which they have again 

 resumed active production. These mines have contributed a con- 

 siderable output of high-grade ore in the past, but for many years 

 were neglected on account of the difficulties presented by their some- 

 what isolated position and irregularity. These difficulties have now 

 been removed to a considerable extent by the driving of a tunnel 

 on the course of the ore and well below the outcrop, which gives 

 access to the lower part of the ore zone and provides an easy haul- 

 age way as well as natural drainage for ground above its level; 

 and by the erection of an independent concentrating plant on the 

 side of the hill to treat the output. The mill is the fourth of the 

 series erected by Witherbee, Sherman & Co. ; one of the others 

 being erected on the Harmony mines and the two older ones on 

 the Old Bed group. 



Cheever mine. The operations at Cheever mine, just north of 

 Port Henry, continued to afford a considerable output of con- 

 centrating ore, mainly from the southern section. Some bands of 

 high-grade magnetite have also been encountered, but the main 

 dependence is the leaner material left in the walls in the previous 

 period of activity. The management has been very successful in 

 dealing with the problems incident to the restoration of the old 

 underground workings and in the treatment of the ore on the sur-
