The Minnesota Devonian consists chiefly of limestone, much of which is 

 abundantly fossiliferous. It probably all belongs in the formation known in 

 Iowa as the Cedar Valley limestone.

DEVONIAN OF MISSOURI 

 BY E. B. BRANSON 



{Ahstract) 



■ The Devonian of northern Missouri contains the following formations : 

 Cooper limestone, Minneola limestone, Calloway limestone, Snyder Creek shale. 

 The Cooper and Minneola are Middle Devonian in age. The fauna of the 

 Minneola resembles that of the Jeffersonville limestone of Indiana and the 

 Grand Tower of southeastern Missouri. It also contains several species com- 

 mon to the Devonian of Iowa. The Cooper and Minneola seas were in part 

 contemporaneous, but the Cooper sea withdrew before the close of Minneola 

 time, and the Minneola spread so as to overlap part of the Cooper. The west- 

 ern boundary of the Minneola sea was about 20 miles east of Columbia, Mis- 

 souri, and the southern boundary stretched from north of Saint Louis to the 

 Missouri north of Columbia.

NICHOLASVILLE {KENTUCKY) WELL 

 BY ARTHUR M. MILLER 



(Abstract) 



A well drilled for oil one-quarter of a mile south of Nicholasville, Kentucky, 

 by a Winchester (Kentucky) oil company was abandoned last summer at a 

 depth of 3,200 feet. Located on the summit of the "Jessamine Dome" of the 

 Cincinnati anticline, at this depth it constitutes the deepest well geologically
