WEST VIRGINIA GEOLOGICAL SURVEY. 14! 



instead of the Harlem. The lower portion, only, of the sand- 

 stone is quarried. It is greenish gray, weathering to brown, 

 coarse and soft, disintegrating badly. The quarry is about 

 100 feet long and extends 30 feet into the hill. This stone was 

 used for concrete aggregate at the Foreman Station. It seems 

 too soft for general building purposes. 



The William E. Donlan Quarry, operated by Bennett and 

 Garrett, just northeast of the mouth of Stonecoal Creek, a I 

 Weston, shows the following section :

Both the Lower Connellsville and the Morgantown Sand- 

 stones have been quarried here, only the lower formation be- 

 ing used at present. The Lower Connellsville appears very 

 hard and durable. The Morgantown is hard, greenish gray 

 and durable, having a smooth uniform appearance. Stone 

 from this quarry is used for general building purposes in Wes- 

 ton, and some of it was used in the construction of the Weston 

 State Hospital. The quarry is about 225 feet long and extends 

 into the hill about 60 feet. A previous Report of the Survey 

 by Grimsley 9 gives a more detailed report of this quarry. 



A sample of the Lower Connellsville Sandstone from the 

 Donlan Quarry was analyzed in the Survey laboratory with 

 the following results, as published on page 470 of Volume IV :

The W. D. Garrett Quarry on the Tom Hale Property,
