The Superintendent of the furnace has furnished me, from his books, 

 the average amount of material consumed in the manufacture of a ton 

 of iron, during one week's run, the product being 136 tons, 440 pounds : 



Native roasted ore 1 56-100 tons. 



Lake Superior ore (New York mines) 28-100 " 



Coal 3i 



Limestone 75 100 " 



Labor, pfir ton $2 72 



William Shields, the Superintendent of the Fannie furnace, estimates 

 the average cost of his iron as follows : 



Three tons coal $2 00 



Two and a half tons ore 5 00 



Three-fourths ton limestone 1 00 



Labor and superintendence 3 00 



Interest and repairs 1 00 



The present capacity of this furnace is fifteen tons per day, and an ad- 

 ditional stack of larger dimensions is now in course of construction. 

 The proprietors of the XX furnace are, also, preparing to erect another 

 furnace ; and believe they will thus reduce the labor account by one 

 dollar per ton, making the cost of the pig $11.00 per ton.

 iron industries of this region, and to whom I am indebted for much sta-
