During the past year the North shaft of the Barton mine has been 

 equipped with a new head frame and shaft house with ore bins, and 

 a number of other additions to the surface plant have been made. 

 An enlarged output may be anticipated in the future operations of 

 the company. 



The ore of the Arnold hill mines is non-Bessemer, though the 

 phosphorus is not specially high. Average samples of the rich ore 

 from the Nelson Bush (i) and Arnold mine (2) show the following

The ore from the Arnold "mine represents the " blue vein " which 

 is mostly martite. The small percentage of nickel and copper is 

 noteworthy. 



Palmer hill. These mines are 3 miles southwest of the Arnold 

 hill group apd i l / 2 miles north of Ausable Forks. During the period 

 of their activity, from about 1830 to 1890, they supplied a total of 

 over 1,000,000 tons of ore. They were operated by the J. & J. 

 Rogers Iron Co., and the Peru Steel Ore Co., in connection with 

 the forges at Clintonville, Ausable Forks, Black Brook and Jay. 



The deposits outcrop near the summit of the hill in a general 

 northeast-southwest direction, though following to some extent the 

 curve of the topographic contours. The elevation is a little over 

 900 feet. 



While the country rock belongs to the same series as that at 

 Arnold hill, being an augite gneiss with occasional hornblende, the
