had to be dropped. It was found that the name Chanute shales 

 was applied to the same formation in one section that the name 

 Thayer shales was applied to in another. In volume III of 

 this series of reports, page 49, it was decided to drop the term 

 Chanute shales and retain the term Thayer shales, as it had 

 been introduced at the same time. One of them necessarily had 

 to be dropped, and the question of priority in no way entered 

 into the question. 



Subsequently, Adams,'" in a government publication, re- 

 stored the name Chanute shales, apparently under the impres- 

 sion that priority demanded it, and the term has been used 

 since then by at least two different governmental publications. 

 At present, therefore, we are forced to decide between the use 

 of the term Chanute as employed by our government upon the 

 advice of Adams, and Thayer, as previously employed by this 

 Survey. As just explained, it is not a question of priority, 

 the two being introduced at the same time and in a similar 

 manner by Haworth and Kirk. The frequency of usage, how- 

 ever, is in favor of the governmental publications, and we bow, 

 therefore, to the greater power and use the name Chanute. 



lOLA Limestone." — The name lola limestone is here used to 

 designate the large and prominent limestone lying first above 

 the Chanute shales. It was first introduced by Haworth and 

 Kirk in 1894, and has been used continuously and without 

 question by every one writing on the geology of this part of 

 the state from that time to the present. 



Lane Shales."" — The term Lane shales was applied by Ha- 

 worth in 1895 to the bed of shales first above the lola limestone, 

 and is here used with the same significance. In those early 

 days, before positive correlations were possible, there was a 

 little doubt as to its exact limitations. At present such doubt 

 is all removed, and, therefore, its exact position may be given 

 as a shale-bed lying between the lola limestone below and the 

 Allen limestone above. 



Adams'" has entirely ignored the use of this name, although 

 it had been in good standing for ten years. In his report on 

 the lola quadrangle, he used in its place the name Concreto, 

 probably in allusion to the manufacture of Portland cement at 

 lola. Why such disregard for well-established usage he does
