cement was seen. The Gorman coal bed is in some of the sections at 15 

 feet above the Middle Kittanning. A notable section was obtained by 

 Mr W. G. Piatt on Castlemans river, in the southern part of the county. 

 It is as follows, the identifications being by the writer :

Irregularity of deposit frequently characterizes all beds of the series, 

 but it is especially characteristic of the Kittannings and lower coal beds. 

 The Upper Freeport limestone is not in this section, but it is present else- 

 where, being almost as persistent as the other limestones in the southern 

 and western portions of the county. The Gorman and Clarion beds have 

 not been recognized in Somerset. 1
