Stratigraphy of Kansas Permian — Beede and Sellards. 87 
creek the Wreford limestone is exposed. The interval be- 
tween this outcrop and the base of the Florence flint, in the 
Crusher quarry is 61 feet, barometrically. This interval 
represents the thickness of the Matfield formation at this 
locality, with, perhaps, some of the upper part of the Wre- 
ford limestone. 
(For the description and definition of the formational terms 
used in this paper see the two papers of Prosser previously cited 
and Folio 109, U. S. Geol. Surv. Atlas. It is also necessary to- call 
attention to Adams' paper, Bull. 211 U. S. Geol. Surv., 1903, in 
which these formations were discussed and given the names pro- 
posed by Prosser in the latter of the two papers referred to which 
appeared about 10 months prior to Adams' paper. Consequently 
Adams' statements concerning the Elmdale, Eskridge, Matfield and 
Doyle formations, pp. 54-59, that "It has not heretofore received a 
distinct name" etc. etc. are in error. More lamentably so because 
from his own statement to me he was thoroughly cognizant of 
Prosser's paper for months before his paper was published. — Beede.) 
Owing to an anticlinal structure north of the Kansas 
line the Wreford limestone appears at the B. and M. R. R. 
junction as just mentioned and is somewhat fossiliferous. 
The section beneath the U. P. bridge is as follows : 
4. Chert, a fourteen inch layer 1 ft. 2 inches 
3. Limestone, irregular and rather thin bedded 3 " 
2. Shales, hard buff 3 " ". 
1. Shales, blue, extending to the creek bed 2 " " 
Total 9 ft. 2 inches 
Numbers 3 and 4 probably represent the upper part of 
the Wreford limestone and are somewhat fossiliferous 
while t and 2 are probably interbedded shales with the 
major part of the limestone below. 
At Holmesville (not visited by the writers) a little over 
20 feet of limestone, according to Knight's section may be 
referred to the Wreford, the lower six feet of which is 
cherty.* The section at the state line was not visited by 
the writers but according to Knight's section there are 35 
feet of Matfield shales, numbers 1 and 2 of his section/ and 
apparently 15 feet of Florence flint, number 3. However 
it seems probable that number 4 of his section contains 
about two feet of cherty limestone belonging to the Flor-
