represents the Putnam Hill limestone. No. 5 is a distinct coal horizon. 

 I have met this coal in many places. Th& shales over it and also the nod- 

 ules of ore, are often rich in coal plants. They are separated from the 

 coal above by the regular under clay of that seam. 



At the Crafts' Iroa Works, now building, at the mouth of Little Mon- 

 day' Creek, Green township, Hocking county, the Baird ore is by meas- 

 urement thirty-seven feet and six inches below the Nelsonville seam of 

 coal. Mr. Crafts has favored me with a measured section of the forma- 

 tion on the company's lands.

I am indelsted to Mr. Crafts for three analyses by J. Blodget Britton of 

 the Baird ore from his lands. 



With an ore of so high a percentage of iron, with so little phosphorus 

 and relatively so little silica, and furthermore, with a coal of great 

 promise, it may be predicted that Mr. Crafts, who combines a scientific 

 knowlpdg^^ of iron-making with much successful practice, will make his 

 furnac'^ an entire success. 



On Monday Creek, a few miles below the Crafts' Furnace, is the fur-
