(Map XIV., No. 14.) 



In this section only one seam of sandstone was seen, viz., the one six- 

 teen feet thick under the upper coal. The whole hill is made up of 

 layers of limestone, with interstratified clays and shales. This is in re- 

 markable contrast with the formation over the equivalent of the Bellair 

 coal at Pomeroy, where in several hundred feet of strata there was not 

 seen a single well-defined stratum of limestone. Directly over the coal 

 at Pomeroy are seventy feet of coarse sandrock. This shows entirely dif- 

 ferent conditions of deposition. 



There are doubtless many more seams of limestone higher in the 

 hills at Bellair, but they were not exposed. Samples of the cement lime- 

 stone were furnished by Col. Poorman for analysis by Prof. Wormley. 

 Nos. 1, 2, and 3 were taken from the lower, and 4, 5, and 6 from the 



upper seam :

Mr. Isaac Booth is successfully manufacturing lime from the* cement 

 stone. The lime is commended by those who have used it. There is no 

 limit to the supply.
