B. IRON ORES. 

 A. GRAY LIMESTONE ORE — (bAIRD ORE). 



1. Gallia Farnaoe, Gallia county. 



2. Howard Farnaoe, Seioto county. 



3. W. B. Brooks, Nelsonville. 



These analyses all represent the Gray Ore, and the samples analyzed 

 could not be distinguished from each other in appearance. The gray 

 variety has never had a good name at Gallia Furnace. The amount of 

 silicious matter is shown to be excessive. The Nelsonville sample from 

 W. B. Brooks's land is fully up to the best standard of the Gray Ore in 

 the southern counties. 



B. BUCHTEL ORE. 



Of the ore that lies eighty-four feet above Coal No. VI, on land of 

 Akron Furnace Company, Bessemer, Athens county, the following anal- 

 ysis was obtained : 



Ferric oxide — - 54.52 



Aluminic oxide ., - 1.52 



Manganese oxide • 1.69 



Calcic oxide. 11.06 



Magnesic oxide .84 



Calcic phosphate 1.15 



Silicious matter 28,21 



Sulphur - --- .27 



99.26 



Metallic iron 38.16 



Phosphorus 34 



The above analysis represents the best grade of the outcrop ore. The 

 results of seven analyses, in which only the metallic iron and the silic- 

 ious matter were determined, are given below. The samples were taken 

 from the stock pile of the furnace during the first month of its operation. 

 A more careful selection of ores has doubtless since been made, by which 

 the yield would be increased. The samples were all calcined ore.
