542 COAL. 



The T. J. Fahey Farm Mine (No. 148 on Map II), on 



Leading Creek, 0.9 mile northeast of Linn, showed 5' 3" of 

 clean coal, at an elevation of 925' B. 



The Lydia Allman Farm Mine (No. 149 on Map II), on 

 Leading Creek, 0.5 mile northwest of Alum Bridge, showed 

 7' 3" of coal, its elevation being 930' B. 



The David Burkhammer Farm Mine (No. 150 on Map 

 II), on Alum Fork, 1 mile north of Alum Bridge, exhibited 4 

 feet of coal, its elevation being 890' B., and coming 43 feet, by 

 hand level, below Mine No. 86 in the Redstone Coal, and 118 

 feet below the great Sewickley Sandstone cliff. 



Pittsburgh Coal, Courthouse District, Lewis. 



In Courthouse District, the Pittsburgh Coal lies princi- 

 pally under drainage, cropping only at two localities, one in 

 the northeastern corner of the district, around Weston, and 

 the other along the southern edge. In both of these regions 

 the coal is too thin for mining or absent entirely from the 

 measures, making it certain that any coal recovered from this 

 seam must be obtained by shafting in the northern and west- 

 ern parts of the district. In those portions of the district 

 where the coal lies under drainage, information regarding its 

 thickness and continuity is not complete. In the eastern part, 

 near the junction of the Grassland and Roanoke Synclines, 

 three diamond drill tests have been made, the record of only 

 one of which (523) was secured. This record which showed 

 no coal, together with the fact that none of consequence is 

 recorded in any of the oil and gas well records of this locality 

 and that none of minable thickness is found in the region of 

 its crop, immediately northward, indicates that the eastern 

 part of the district contains no Pittsburgh Coal of minable 

 value. In the western part three core tests have been drilled 

 in the Copley neighborhood, the records of which could not 

 be secured. Numerous oil and gas well records were ob- 

 tained, however, and a sufficient number of these record coal 

 to warrant the assertion that a considerable body of Pitts- 

 burgh Coal exists in this part of the district, but the fact that 

 many of the records that are apparently complete fail to record 

 the coal, indicates that it is patchy and that extensive tests by
