into two separate beds by the Jane Lew Sandstone. It is the 

 largest red shale horizon of the Conemaugh Series and is dis- 

 tinguished further by the fact that the next red beds of con- 

 sequence appearing in the measures are about 1000 feet below 

 it, there being only occasional streaks of red below the Bakers- 

 town and Brush Creek Coals. This shale is frequently used 

 for building and paving brick manufacture in other counties 

 and should furnish a large amount of good material for this 

 purpose in Lewis. 



The Jane Lew Brick and Drain Tile Works has recently 

 opened a cut in this shale at the south end of Jane Lew, 

 Hackers Creek District, where the following section was se- 

 cured :

Mr. Fred Flesher, Manager of the Brick Company, shipped 

 a barrel of this shale to State Road Engineer A. D. Williams 

 at Morgantown, who has had a test made of it for brick, the 

 results of which are given in Chapter XII. 



THE JANE LEW SANDSTONE. 



At 15 to 25 feet below the top of the Pittsburgh Red Shale 

 a sandstone frequently occurs in Lewis County that has not 

 been previously described or named. Since its presence in 

 the measures would lead to confusion unless definitely rec-
