The following is a combined section measured at this 

 place : — 



Thickness 

 Feet. Metres. 

 6 — Soil and drift 1-5 • 152 



Onondaga limestone. 



5 — A very cherty, bluish-grey limestone 

 in which fossils are abundant. Much loose 

 material, weathered out of these beds, occurs 

 in the fields to the north, where collecting is 

 good 3-6 1 • 118 



4 — Cherty, calcareous layers with an 

 abundance of coarse sand intermingled. This 

 portion sometimes becomes a true conglom- 

 erate in which the pebbles are fossiliferous 

 Oriskany sandstone o • 6 • 203 



Oriskany sandstone. 



3 — Coarse sandstone, partly covered. . . 2-5 -763 

 2 — Coarse grained, friable, white to 

 yellowish sandstone with an abundance of 

 fossils in certain spots. At some places, 

 especially in the upper part, this sandstone 

 contains occasional concretion-like bodies, 

 which have been cemented into masses re- 

 sembling quartzite. The contact of this 

 sandstone with the underlying rock is very 

 uneven, and the lower layers of sandstone 

 contain sub-angular and rounded fragments 

 of the underlying limestone. The thickness 



varies much from place to place 17 5 • 185 



1 — Buff to brown and drab dolomitic 

 limestones which are rather compact and 

 usually distinctly banded. These beds ex- 

 tend to the bottom of the limestone quarry 



and contain a few fossils 16-5 5-033 



The fossils occurring in the different strata at this 

 point are indicated in the first column of the table on
