20 b. Alluvium and Bluff. 



20 a. Gravel, (equivalent of Orange 



Sand of Tennessee). 

 19. Tertiary,(its details not yet studied). 

 14 c. Upper Coal Measures. 

 14 b. Lower Coal Measures. 

 14 a. Millstone Grit. 

 13 c. Chester. 

 13 b. St. Louis I. s. (Warsaw at base). 



13 a. Keokuk and Waverly. 



10 c. Black Shale. 

 ( 9 c. Corniferous or 

 \ Upper Helderberg. 



9 a. Cauda Galli. 



5 c. Niagara. 



4 c. Cincinnati. 



4 a. Trenton. 



1. By Mr. John E. Procter, assistant of Prof. N. S. Shaler, State Geologist of Kentucky. 



2. The geological survey is in progress, and the -formations of the State are not fully determined. 



3. Bagdad. To the south of Bagdad can be seen an isolated knob, which is capped with the 

 Niagara group. 



4. Frankfort. The Kentucky River runs in Trenton at this point. It reaches up the bank of 

 the river above the town, as high as the railroad tunnel. 



5. Mount Sterling. From here can be seen to the eastward, hills capped with St. Louis lime- 

 stone, and the Conglomerate sandstone at base of Coal Measures. 



6. Shepherdsville. Salt Eiver at this point probably cuts down to the Corniferous limestone. 



7. Colesburg, at base of Muldraugh's Hill. This hill extends around Central Kentucky, from 

 the mouth of Salt River on the west to the confines of Lewis and Mason counties on the east, retain- 

 ing nearly for entire length of the great circle the same geological formations, viz; Black shale at 

 base ; Keokuk or Waverly shales ; Keokuk limestones, becoming more silicious to the eastward, until 



sub-conglomerate
