THE MINING AND QUARRY INDUSTRY IQIO 35 



Benson Mines; and the Salisbury Steel & Iron Co., Salisbury Cen- 

 ter. The producers in southeastern New York were the Sterling 

 Iron & Railway Co., Lakeville, and the Hudson Iron Co., Fort 

 Montgomery. The single producer in the limonite region east of 

 the Hudson river was the Amenia mine. The output of hematite 

 was made by the Old Sterling Iron Co., with mines near Antwerp, 

 Jefferson county; Furnaceville Iron Co.; the Ontario Iron Ore 

 Co., Ontario Center; and C. A. Borst, Clinton. 



Arnold. An important transaction in iron ore lands, which may 

 lead eventually to a renewal of mining in southern Clinton county, 

 is the recent purchase by Witherbee, Sherman & Co. of an exten- 

 sive tract in the townships of Black Brook and Ausable, including 

 the holdings of J. N. Stower and the Peru Steel & Iron Co. A 

 large number of magnetite deposits occur wit'hm the area and al- 

 together it may be considered one of the most promising properties 

 in the Adirondack region. It embraces several old mines such as 

 the Arnold, Cook, Mace, and Battle which at one time supported a 

 very active industry in connection with the local forges. The Ar- 

 nold mines have been intermittently active for the last century and 

 were worked as late as 1906, since which time, however, no ore has 

 been mined in this district. 



Exploration of the property by the new owners has been under 

 way since the latter part of 1909 and has already resulted in some 

 encouraging developments. The Battie and Cook ore bodies, which 

 so far have received most attention, have been demonstrated by sur- 

 face excavations and diamond drill tests to be of much greater 

 thickness and continuity than had been revealed in the earher work. 

 The two appear to form a practically connected deposit extending 

 for a mile and a half or more on the strike. The ore pinches to 

 small size and shows slight offsets in places, but as a whole exhibits 

 a degree of regularity unusual tO' most Adirondack occurrences. It 

 is entirely of concentrating grade, the magnetite being intermixed 

 with quartz and dark silicates, or else interleaved with bands of 

 rock so as to require mill treatment. The thicker portions of the 

 deposit measure as much as 75 or 80 feet between the walls. Tests 

 in the concentration of the magnetite have been conducted b}^ an 

 experimental plant set up in the Arnold mill nearby. 



Benson Mines. The mines of this place were active during only 

 a few months of the past year, having been closed in the late summer 

 after a brief run. The general plan of operations proved unsatis- 

 factory for economical production and it is unlikely that they will 

 be reopened until a complete reorganization can be effected. The
