UPPER PALEOZOIC FORMATIONS OF KANSAS 705 



the Cincinnati series of the Ordovician in Minnesota, for which 

 he proposed "a new name .... Wykoff beds — from the town 

 near which the best exposure known occurs." 1 and this he later 

 called the Wykoff formation. 2 The only difference is that the 

 name of the Minnesota town is spelled without a c. In 1895 

 Professor Haworth proposed the name "Osage City shales" for 

 the rocks included between the top of the Topeka limestone and 

 the base of a thin limestone overlying the Osage coal ; while 

 about 150 feet of the superjacent rocks in the vicinity of Bur- 

 lingame were named the Burlingame shales. 3 Later in the same 

 year both divisions were more fully described by Professor 

 Haworth ; 4 but the upper limit of the Burlingame shale was not 

 precisely defined. The following year Mr. Hall applied the 

 term "Burlingame limestone " to eight feet of limestone which 

 " covers the third and last heavy bed of shales in this section " 

 with a thickness of 150 or 200 feet. 5 



This shale was apparently regarded by Mr. Hall as the Bur- 

 lingame, since he used that name in the list of subjects at the 

 beginning of his chapter, 6 and then the heading following that 

 of the Burlingame limestone is the " Systems above the Bur- 

 lingame shales." 7 



In 1898 Professor Haworth stated that " subsequent work 

 has shown the unimportance of" the thin limestone overlying 

 the Osage coal, " so that it will not do to depend upon it as a 

 division line marker. Neither will the Osage coal serve such a 

 purpose, as it is by no means continuous .... From these 

 considerations it seems desirable to let the name Osage apply to 

 the entire shale bed above the Topeka limestone and below the 

 Burlingame limestone . . . This renders the name Burlingame 

 shales superfluous and therefore it will be dropped." 8
