of Indiana University, who has been associated with the writer 

 in this later study, has rendered most efficient service in the field 

 and other work necessary for this revision. Dr. George I. 

 Adams, of the United States Geological Survey, spent several 

 days with Dr. Beede in examining part of the area of the Cot- 

 tonwood Falls quadrangle, and Mr. F. B. Weeks has also kindly 

 furnished the author with references to the descriptions of forma- 

 tions from the United States Survey card catalogue of geologic 

 formation names. 



CLASSIFICATION. 



WABAUNSEE STAGE. J 



None but the upper rocks of this stage are exposed on the 

 Cottonwood Falls quadrangle and the lower ones, exposed to the 

 eastward, have not been carefully examined by the writer. 



Burlingame limestone. — At the base of the Wabaunsee is a 

 conspicuous and persistent limestone from seven to twelve feet 

 in thickness, the lower limit of which is regarded as the lower 

 line of that stage. It was named and briefly described by Hall 

 in 1 896 2 from outcrops near Burlingame and since then it has 

 been traced from Nebraska across the state to Oklahoma. 3 



This limestone is frequently composed of two layers, gray to 

 brown in color, separated by shale, and forms a massive ledge. 

 This is apparently the division which was termed "limestone 

 number 9" by Professors Haworth and Kirk, in 1894, exposed 

 near the junction of the Cottonwood and Neosho rivers, which 

 they stated "may be called the Wyckoff limestone .... on 

 account of its great exposure in the vicinity of Wyckoff. 4 " This 

 name, however, ought to be considered a synonym, for Dr. Sar- 

 deson had already given an almost identical one to a division of
