546 COAL. 



the oil and gas wells record it and some do not. Several 

 core tests have been made in the district, but, unfortunately, 

 nearly all the operators who drilled them expressed themselves 

 as unwilling or unable to furnish them to the Survey, and the 

 information that they contain is therefore denied to the pub- 

 lic. In most of such cases a justifiable suspicion exists that 

 the diamond drill has not proved a satisfactory thickness of 

 coal. The core test (754), at the mouth of Slidinghill Run at 

 Stouts Mills, showed 7' 8" of coal, while another one (711) 

 on Sand Fork, near the mouth of Indian Fork, showed only 

 a streak of coal at the Pittsburgh horizon. Figure 6 embodies 

 the best information available regarding the coal in this re- 

 gion, showing those regions where it is known to be good as 

 well as those where it is defective or uncertain. In the region 

 where the coal crops, numerous openings were examined.
