also studied the Nebraska City section and, although he has not 

 traced the strata from the mouth of the Great Nemaha to that 

 locality, still he says: "the rocks at Minersville [formerly Otoe 

 City] and Nebraska City are just what we should expect if 

 Meek's correlations were correct, as a comparison will show: At 

 the base of the Nebraska City section are several layers of 

 limestone, then, above, a thick bed of shales and sandstones, 

 coal and limestone, then over ioo feet of shales which contain 

 a second coal, and above this another limestone, which makes it 

 agree in stratigraphic succession, as it does in fossils, with the 

 Topeka section. Thus, considering the great care with which 

 Meek did the work, we can but come to the conclusion that his 

 correlation is probably correct. 



" 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 sec- 

 tion, corresponds to the Topeka section from the Topeka lime- 

 stone nearly to the base of the Burlingame limestone." 1 While 

 in another article, in discussing Meek's reference of the sand- 

 stone at the mouth of the Great Nemaha to a stratigraphic posi- 

 tion above that of the Nebraska City section, he says : " If this 

 be true, it throws the section at Nebraska City in the same 

 general horizon with the Topeka-Osage coal, if it be not 

 identical with it, and the limestone at the base of the section 

 would then represent the Topeka limestone, or a part of it. 

 While I have not been over the ground between Minersville and 

 Rulo, Neb., I am of the opinion that this conclusion is correct." 2 



The writer is inclined to consider the conclusion of Mr. 

 Beede regarding the age of the Nebraska City beds as correct ; 

 and if so the rocks composing this section are equivalent to the 

 Topeka limestone and Osage shalesof the Kansas River section, 

 which form the upper part of Professor Haworth's Shawnee 

 formation of the Upper Coal Measures. 3 This correlation agrees
