near Topeka, to the Nebraska line. 1 The Burlingame limestone 

 was named and described by Mr. Hall, in 1896, from outcrops 

 near Burlingame, Kansas, 2 and since then, through the efforts of 

 Professor Haworth and Messrs. Adams, Bennett, and Beede, its 

 outcrop has been traced 3 from Nebraska across the state to 

 Oklahoma. In its stratigraphic position this limestone is now 

 regarded as forming the basal subdivision of the Wabaunsee 

 formation, which is thus clearly marked, as the limestone forms 

 a prominent escarpment along the greater part of the line of 

 its outcrop across the state. The lower part of the Wabaunsee 

 formation was described from exposures along Mill Creek and 

 the Kansas River between McFarland and Topeka, its base being 

 marked by the Silver Lake coal. At that time the Silver Lake 

 coal, exposed in the Kansas River bluffs west of Topeka, was 

 supposed to belong in the same horizon as the Osage coal and 

 to form a zone capable of being traced for two thirds or more 

 of the distance across the state. 4 Mr. Beede has shown later 

 that the Topeka coal, 125 feet below the Silver Lake coal, is the 

 Osage coal, 5 and since the higher coal is not conspicuous south 

 of the Kansas River it does not serve as a continuous line of 

 division for the base of the Wabaunsee formation. Along the 

 Kansas River, however, the Burlingame limestone 6 is only from 

 15 to 35 feet above the Silver Lake coal, and as this limestone 

 forms a marked outcrop extending entirely across the state, it 

 serves as a definite line for the base of the Wabaunsee forma- 

 tion, as has been suggested by Professor Haworth. 7
