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 
IQII, in actual figures 675,512 long tons against 734,353 long tons 
in I91I. 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 Pore ienry ironiOnesCo: ; 
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-
