(See Map XII., No. 2.) 



The entrance to the mine near which this section was taken had fallen 

 in, and no measurement was possible. On section 13, on the land of 

 Robert Murray, the following section was taken : 



Ft. In. 



1. Sandstone and conglomerate 15 



2. Shale 6 



3. Coal 4 



4. Slate t OJ 



5. Coal 1 9 



(See Map XII., No. 16.) 



The coal at this point apparently works larger than is usual for this 

 seam. The general quality is excellent. 



About a mile south of Bysville the Cambridge seam was found, by 

 boring, to be twenty feet below the level of Wills Creek, and reported to 

 be five and a half feet thick. 



VALLEY TOWNSHIP. 



This township lies south of Jackson. The valley of Wills Creek ex- 

 tends through it, and by this stream and its tributaries the whole area 

 of the township is drained. The whole township lies above the Cam- 

 bridge coal, unless possibly a small part of the low valley in section 21 

 and in that vicinity may be low enough to reach the coal. A geologi- 

 cal section was taken about a mile and a half south-east of Point Pleas- 

 ant, as follows : 



Ft. In. 



1. Shale 25 



2. Limestone, fossiliferous 1 o 



3. Yellow shale 65 



4. Limestone (Ames limestone), fossiliferous 4 



5. Shale, with white clay at bottom 25 



6. Sandstone 26
