The ore stands up well, and, by leaving pillars, with arched 

 roof in the galleries and drifts, no timbering is necessary. There is 

 comparatively little water in the mine. The serpentine is not so firm 

 as the ore, and is full of slickensides surfaces. Small mine cars are 

 used on the narrow gauge tramways in the mine drifts. A skip 

 track runs to the bottom of the open pit. A branch railroad three 

 miles long, connects this mine and the Dickson with the main line of 

 the R. W. & O. R R., near Antwerp, although in a due east course 

 the latter is less than a mile away. 



The Dickson and Old Sterling ores are sold to furnaces on the 

 Hudson river and in Eastern Pennsylvania, and some to Ohio. The 

 ease with which the Old Sterling ore is smelted, being almost self- 

 fluxing, creates a demand for it in mixtures with other more refractory 

 ores, and even where the freights make it expensive. The total out- 

 put of these mines is estimated by Mr. E. B. Bulkley, president of 

 the company, at 750,000 tons. 



KEENE MINE, Antwerp, Jefferson County. — This mine is the 

 property of the Rossie Iron Works, Chas. S. Westbrook, manager. 

 It is less than a mile west of Keene station on the R. W. & O. R. R., 

 and near the county line. Sandstone here caps the ore, and the floor 

 is a siliceous conglomerate in part, with some serpentine. It has 

 been worked over 500 feet on the line of strike and is 400 feet deep, 

 and the ore has been on an average twelve feet thick. Work at 

 raising ore stopped in the autumn of 1887, but the water is still 

 kept out. 



CALEDONIA AND KEARNEY MINES, Rossie, St. Lawrence 

 County. — The mines of the Rossie Iron Works are in the south- 

 eastern part of Rossie, near the Jefferson county line, and six miles 

 from Gouverneur village. The southern working's constitute the 

 Caledonia ; the Kearney mine lies north and north-east and a part of 

 it is in the town of Gouverneur.
