12. PENN TOWNSHIP. F\ 287 



Little Juniata about half a mile north of King's mill and 

 thence in the same direction southwestward, but it nowhere 

 enters Penn township. The lowest fossiliferous layer in 

 the group now under consideration which is found in the 

 township is the remarkable Kingsmill sandstone of this 

 report, which crosses near the northern line and is well ex- 

 posed between King's mill and Linton's hill. The sections 

 given herewith are found in the northern part of the town- 

 ship and most be considered together though the former 

 really belongs to Wheatfield township. It is, however, 

 placed here to avoid the separation of what are in reality 

 only the lower and upper parts of the same section. This 

 is the only instance I have met with of fossiliferous shales 

 and limestones above the Kingsmill sandstone or base of 

 the true Catskill. This exposure is only made by the re- 

 cent cutting of a new road and possibly had a similar op- 

 portunity existed elsewhere similar beds might have been 

 displayed. 



All the beds of the Linton's Hill section (see page 290) 

 lie beneath those of the Kingsmill section described below, 

 on page 289. 



The peculiar sandstone bed with its crowded Lamelli- 

 branch casts at the top of the Linton's Hill section appears 

 near King's mill, and is there evidently many feet below 

 the base of the Kingsmill section, probably 200 to 300 feet 

 below it. By combining the two sections and including the 

 space between them (200 ? feet,) the space between the base 

 of the lower section and the lowest layers of the Chemung- 

 Catskill (50 feet ?) and the space to the thin coal seam in 

 the Dellville sandstone lying above the top of the higher 

 section, (about 80 feet,) we obtain a section of the Lower 

 Catskill and Chemung-Catskill rocks about 1300 feet. 



The Kinr/smill section. 



The following beds are exposed by a side cutting on a 

 road running nearly X. W. and S. E. made about twelve 

 months ago, and on the N. E. side of the road. At the S. 

 E. end or top of the section, where the cutting begins, near 

 the little run, the rocks dip 40° S. 20° E.:
