it is about nine feet thick and single ; in the second eight 

 and one-half, and sii||le ; while in the third it is double with 

 the lower division averaging between nine and ten feet, and 

 the upper varying from two to five and one-half. 



RELATIONS OF THE PITTSBURG AND THE SUPERIOR COALS. 



It has been stated that Coals VIII a, VIII 6 and VIII c of 

 the Ohio section are to be seen only in the neighborhood 

 of Wheeling' and that their relation to coal VIII would be 

 considered especially. Coal IX, though observable over a 

 much larger area in Ohio is evidently related to VIII in the 

 same manner as the intermediate beds. That the matter may 

 be clearly set forth, the following sections are introduced : — 



No. I is from the Central Ohio railroad, eight miles from Belleair. 



No. II is from New Egypt, Belmont Co., Ohio. 



No. Ill is from Flushing, Belmont Co., Ohio. 



No. IV is from near Cadiz, Harrison Co., Ohio. 



No. V is from near York, Jetlerson Co., Ohio. 



No. VI is from near Uniouport, Jefferson Co., Ohio. 



No. VII is from Knoxville, Jefferson Co., Ohio (H. Newton). 



The section on the railroad is representative of a consider- 

 able area and, in all important points, can be duplicated at 

 Belleair and at many localities along Wheeling creek and the 

 Ohio river. The sections obtained here cannot be directly 

 connected with the others given, as high dividing ridges sur- 

 round the portion of the state represented by Sect. I. The 

 Cadiz section is virtually characteristic of eastern Harrison, 

 but northwest the limestone No. IV becomes thinner as we 

 approach the outcrop.
