Allen Limestone.*® 
The name Allen limestone is here used to designate the lime- 
stone first above the Lane shales. There has been a large 
amount of discussion regarding the names of the two lime- 
stones first above the Lane shales. In its early work this Sur- 
vey was led into error a number of times on account of a lack 
of proper correlation. After Adams*¢ joined the United States 
Geological Survey he likewise was incorrect in treating this 
subject. All along it has been known that there were two 
principal limestone formations moderately close together and 
sufficiently persistent to form a prominent line across the state. 
In 1894 these two were not differentiated, and in the section of 
the Neosho river were called by Haworth and Kirk the Bur- 
lington limestone. In the same publication, in a section from 
Coffeyville to Lawrence, Haworth recognized a limestone at 
Carlyle, which he named Carlyle, and these two limestone 
masses at Garnett and Ottawa, which he named the Garnett 
limestone. In volume III of this series of reports the term 
Garnett was used, Bennett having previously determined by 
field-work that the exposure at Carlyle was the lower of these 
two. In that way the name Carlyle was dropped. Adams** 
decided that the lower member, or possibly both of these, was 
the limestone mentioned by Swallow as the Stanton limestone. 
Later, in United States Geological Survey Bulletin 238 he 
abandoned the term Stanton and introduced the terms Allen 
and Piqua for these two limestone beds. 
Our investigations have shown conclusively that the lime- 
stone named the Stanton by Swallow in his report for 1866 is 
the upper one of these two much discussed limestone forma- 
tions. Inasmuch as we are now ready to give detailed descrip- 
tions and detailed names we adopt the name Allen for the 
lower one of the two, because it seems to be the first name sug- 
gested for this specific formation, and we retain the name Stan- 
ton for the upper one because Swallow suggested it as early as 
1866. Our former name, Garnett, may be used, should any one
