In the light of the facts already given, these registers are perfectly 
clear and unambiguous. In the first, the flinty rock, No. 19, is the 
Lower Mercer limestone, and the coal below it is, of course, the Lower 
Mercer coal. No. 12, the “very hard rock,” is the Upper Mercer lime- 
stone, and Nos. 3, 4, 5 and 6 mark the horizon of the Clarion Upper 
coal. 
In the second record, Nos. 21 and 22 indicate the Lower Mercer 
horizon, Nos. 13 and 14 the Upper Mercer, and Nos. 4, 5 and 6 show 
the Clarion coals in the same order in which the seam is found to the 
westward, No. 8 may stand for the Clarion Lower coal.
