to T calcareo-argillaceous and earthy Same locali- 

 concretionary limestone. Half a mile ty as the last, 

 east of Liberty it appears thus : 



1. 3' shales. 



2. 14" blue limestone. 



3. 8" shales. 



4. 6" blue limestone. 



5. 2' shales with a thin bed of con- 

 cretionary limestone — fossil plants. 



Limestone, distinctly separated lithologi- 

 cally into two parts ; the upper 5', the 

 lower 11'. The upper part is generally 

 very fine-grained, and in two beds ; its 

 color flesh, dove, or fawn ; and con- 

 tains particles of calc spar, but which 

 are often absent, leaving minute cavi- 

 ties. The lower 11' is white, light 

 gray, or bluish-drab, and contains Pro- 

 duces costutus, Pr. Prattenianus, Pr 

 punctatus, and Productus (small species 

 like Pr. Wabashensis). 



Clay shales. 



Bituminous shales. 



Argillaceous shales ; upper part dark, 

 and containing many small round cal- 

 careous concretions. 



18' to 22' " Bethany Falls " limestone. 

 Upper 7" is fine-grained dove-colored, 

 brittle, shelly, and fucoidal, scarce- 

 ly containing fossils. The lower part 

 is irregularly and evenly bedded, light 

 grayish, or drab crystalline, weathering 

 buff ; contains Prod, costatus and Pr. 

 splendens. Springs abound at the base.

Blue and bituminous shales ; 1^ feet at 

 bottom consists of bituminous shales, 

 and at top we have 1' to 2£' of blue ar- 

 gillaceous. 



Even-bedded ashy-blue limestone, jointed 

 perpendicularly. Near Randolph it is 

 16" in thickness, but eastward it be- 

 comes thinner. 



Nodular limestone and shales abounding 

 in fossils — Pr. tubulospinus, Pr. costatus, 

 Ortkisina Missouriensis, Or. nmbraculum. 



Fine-grained, hard, bluish-buff, silico-fer- 

 ruginous limestone; weathers brown; 

 is rather irregularly bedded. 



Shales, mostly sandy ; towards the lower 

 part are calcareous beds containing 

 Myalina SwaMovti and Pr. Noncodii. 



Buff and gray limestone. 



Shales and sandstone. 



Gray crystalline limestone.
