[margin circled 47] 
C-2 feet of hrackly or mealy 
Is simply packed with 
Renesselandia - long slender ones 
in lower 3/4 but large missouriensis types in upper part = 6693 B 
C - Dove Is with nodules 
of lime + shale partings - bed 
very irregular in thickness 
Shale seam at top. 
E - Dove Is Dev. or Miss. 
Found a pocket of black shale under the Rensselandia bed which I 
suspect is 
Pennsylvania. Similar black 
shale was seen filling cavities in The Burlington. 
I suspect therefore that the black shale is a cavern filling occupying any 
level in the limestone. Black shale = 6693D
