5. Concealed, 80' 



6. Sandstone, massive, 10' 



7. Concealed, 30 



8. Sandstone, 15' 



9. Concealed, 15' 



10. Flaggy sandstone, 10' 



11. Concealed to R.R. level (766' A. T.,) 40' 



12. Concealed, 20' 



13. Massive sandstone to level of Martin's creek, 20' 



Nos. 1, 2 and 3 very probably represent the massive rock 

 with calcareous breccia seen at 1195' A. T. in the section at 

 Bell's mill (Fig. 51) one mile below Foster, since this would 

 give a dip of (1195' — 995 / )=200 / in the 3^ miles south, or 

 about 57' per mile, which is about what we have found for 

 the fall of the rocks between Foster and Nicholson. 



The calcareous breccia imbedded here between two masses 

 of sandstone, seems to be continuous at this locality, and 

 great blackened bowlders of it lie scattered over the surface 

 below. It is most probably the parent bed of the same class 

 of bowlders that are found constantly along Martin's creek 

 valley between Nicholson and Foster. 



The shale below is dull-red and somewhat sandy. 



Flagstone Quarry. — The flaggy sandstone 40' above R.R. 

 level is extensively quarried at Nicholson, and furnishes 

 very smooth flagstone of a greenish-gray color and 2" to 4" 

 thick. 



26. Springville, in Susquehanna county. 



This lies directly west from Lathrop and has Wyoming 

 county for its south boundary. 



The drainage is all southward by way of Meshoppen and 

 White creeks directly to the Susquehanna river. 



The rocks of the township are about the same as those 

 found in Lathrop, to the east, and all belong to the CatsJclll 

 series. 



The sandstones of this system are frequently seen forming 

 cliffs in the hill, but as no streams cut very deep channels 

 through the rocks, the exposures are poor and nothing like 

 a section can be obtained.
