Localities. 



No. 1094. Northwest corner of the J. W. Duncan headright. 



No. 1095. From a different portion of same headright. 



No. 1096. Dr. Bradfield's farm, James N. Gray headright. 



No. 1097. James N. Gray headright, three and one-half miles south of Daingerfield. 



No. 1098. Leander Kidd headright. 



No. 1099. Leander Kidd headright. 



These ores are very generally mixed in the banks, and it is very probable 

 that every ton of ore mined in any portion of this field would contain more 

 or less of each class here represented. An average sample of the whole 

 combined would give the following analysis: • 



Ferric oxide 7 7 . 94 



Silica 8.18 



Alumina 3 . 46 



Phosphoric acid . . 0.31 



Sulphuric acid . 04 



Lime . , Traces. 



Loss on ignition 10 . 04

Metallic iron, 54.56. 



One hundred parts of iron contain 0. 247 of phosphorus. 



This ore if calcined would give from the above analysis 60.69 of metallic 

 iron. 



These ores compare favorably with the limonites of Alabama of the sub- 

 carboniferous metamorphic regions of that State, and the Tuscaloosa forma- 

 tions, which Dr. E. A. Smith ranks second in importance in the production 

 of iron in Alabama.* 



The ore field in the immediate vicinity of the town of Daingerfield consists 

 of two high hills lying on the Henry Proctor headright and extending in an
