worked along the tributaries of Short Creek on the south and west sides, 

 as well as on Mclntyre's Creek on the north. Towards the western line 

 the surface is lower than elsewhere, and the coal, though more easily- 

 accessible, is hardly so valuable as in the eastern portion,- as the ravines 

 cut down to the coal and break it into comparatively small areas. 



The sections of the rocks overlying Coal No. 8, as seen in this township, 

 are quite as interesting as those obtained in Mt. Pleasant. On the road 

 leading from Short Creek to Smithfield the exposu're is imperfect, except 

 near the base. We find there —

Here the interval between 8 and 8c again shows a marked diminution, 

 having, in only three miles, decreased fourteen feet.
