Variegated shales, (calcareous. | 



Red shale, (Calcareous.) 



A good section through the greater part of the red shale 

 is shown west of Waggoner's mill along the roadside, with 

 a continuous dip of from 15°-30° N. X. W. The Ore sand- 

 rock is quarried in the hill at the top of the section, and 

 about 120 feet of olive calcareous shale with a bed of f os- 

 siferous limestone succeed it. Then follow about 450 feet 

 of red shale which do not include the whole of the stratum. 



Waggoner' s Mill section, { V.) 



470'— Red shale exposed with dip from 0°-80° in middle of syn- 

 cline. 

 3' Four small thin beds of green shale. 

 2' Hard green sandstone. Dip 70°. 

 120' Space concealed, but the lime shales and sandstone show in 

 field east of mill with abundance of Beyrichia notata. 

 Dip varying. 



20' Ore sand rock. Dip 10° S. S. E., Total, 615' 



Green shale. 



Cissna s {Cedar) Run section, {Onondaga.) 



The road running south from the main turnpike road 

 through the valley shows an interesting section across the 

 beds lying at and below the base of the Lower Helderberg 

 limestone. They are the Scalent variegated marls of the 

 first survey, and in part the Scalent gray marls overlying 

 them. A noteworthy point is the existence of Lepertlitia 

 alia almost to the bottom of the section so far below the 

 base of the limestone. 



It must also be remembered that the top of this section 

 is many feet below the true limestone beds which are shown 

 about a mile to the westward, but a section of which can 

 scarcely be obtained there. Near Robert Clark's farm on 

 the roadside the limestone beds maybe followed down each, 

 containing L. alta until they appear to be almost pure ar- 

 gillaceous shales.
