If the foregoing statements are correct, we are forced to the conclusion that 
the Nebraska City section of Meek, from the base of the lower limestone to 
the top of the Minersville section, corresponds to the Topeka section from the 
Topeka limestone nearly to the base of the Burlingame limestone. Looked at in 
this light it also agrees very well with Prosser’s work. It makes his remark that 
‘These shales are mostly of a drab color, somewhat micaceous as well as clayey, 
and resemble those used for vitrified bricks at the Topeka, Kan., works,”’ quite 
significant. The location of the Burlingame limestone at Rulo also agrees very 
well with his Cottonwood limestone four miles west of Auburn, Neb., 345 feet 
above the Missouri river. It is true that the shales corresponding to the Miners- 
ville shales in the Topeka section are less highly colored and, in places, less 
sandy, but on the whole I think this is of little importance in so long a distance. 
Besides, these highly colored shales can be correlated here as well as anywhere 
between the base of the Permain and the lower part of the Upper Coal Measures, 
which are certainly far below them, with one exception, which is considerably 
above the Topeka section, and here, I think, the succession of strata and the 
fossils are both different from the Missouri river sections. 
At any rate, it can be stated with a moderate degree of certainty that the 
rocks at Nebraska City, Neb., and at Topeka, Kan., belong to the same general 
horizon.
