836 GBOLOGY OF OHIO. 



Creek, are several valuable bodies of the great seam. The coal on the 

 Jared Dennison farm, in Monday Creek township, Perry county, was re- 

 ferred to in the First Report. I afterward revisited this region and exam- 

 ined the coal on this ridge more carefully, and found some of the finest 

 coal in the State. A good exposure of the seam was found on the land 

 afterward bought by the Baird Iron Company, and the coal was thought 

 to be very pure and Well adapted to the blast furnance. Ores of excel- 

 lent quality from this region had for many years been taken to the Logan 

 furnace, with which Mr. Baird had formerly been connected. Hence, 

 with tried ores and coal of the highest promise, it is not to be wondered 

 at that the pioneer furnace in this immediate coal field should be located 

 at this point. It should b-; stated that Mr. Baird had previously used 

 the coal of the same seam from the Straitsville mine in the furnace 

 under his management, at Columbus. To the late Samuel Baird, Esq., 

 must, therefore, be accorded the honor of being the first to realize in 

 practice the value of the coal of this field as an iron-making coal, it 

 being first successfully used by him at Columbus, and afterward at the 

 Baird Iron Works. The Winona furnace, on Little Monday Creek, will 

 doubtless be able to obtain coal from the Dennison lands, or from that 

 vicinity. A tram-road would take down both fuel and ore. South of 

 Gore are similar out-liers of coal, from which the Thomas furnace ob- 

 tains its fuel. Two or three miles north of the Baird furnace I found 

 what I thought to be the Nelsonville seam, on the land of George Koch- 

 ensperger. No levels were taken, nor intermediate sections, and there 

 may be a mistake in identification, but I think not. The seam is much 

 thinner than farther south, but the loss is, as usual, chiefly in the di- 

 minution of the upper bench. The whole section taken here and on the 

 adjacent land of -Jacob Martzoff is as follows :
