subdivided by Hennen 5 into the Upper and Lower Marietta

 30 to 50 feet thick. It was noted at the head of Tanner

 and at the head of Laurel Fork at 1165 feet. In Chapter IV

 noted along the ridge road at the head of Walnut Fork of Fink 

 Creek where it is 30' thick at an elevation of 1195' B. In 

 Chapter IV the shale is noted in the sections for Cedarville, 

 Hurst and Newberne, and in the present Chapter it appears 

 in that for Dry Fork. 



LOWER MARIETTA SANDSTONE.

 Sandstone group first described by White 7 and later classified 

 by its present title by Hennen 8 , is of frequent occurrence in 

 the Dunkard Measures of Lewis and Gilmer. It is usually 

 light brown, micaceous and flaggy. In Lewis County it was 

 noted at the head of Right Fork of Freemans Creek, cropping 

 flush with the Annie Joyce No. 1 (206) well, at an elevation of 

 1140' B. In Gilmer it was noted on Sand Fork, one mile north-
