BELMONT COUNTY. 287 



ville cement obtained from this roclv has no superior among the cements 

 manufactured in our country. This layer is present throughout the 

 county, except in the north-west, and invariably presents the same physi- 

 cal character. Underlying Coal No. 86, on the river, is a limestone which 

 yields a good hydraulic lime. 



Marl. — The calcareous shales interstratified with the limestones under 

 Coals Nos. 86 and 9 will prove useful as marls. The analysis of one of 

 these has been given (Pease township). 



Fire-clay. — The clay from below the coals is usually too ferruginous to 

 be of any value. The deposit in Pease township may prove valuable, 

 but the analysis is not encouraging. Clay for bricks is obtained from the 

 subsoil. 



Water. — The county is well supplied with water for all purposes.
