PROSSER: UPPER CARBONIFEROUS OF SOUTHERN KANSAS, LAL 
Finally, Mr. Vaughan, of the U, S. Geological Survey, who is 
studying the Upper Paleozoic and Cretaceous rocks of Oklahoma 
and Indian Territories and southern Kansas, under the direction of 
Prof. Robert T. Hill, speaks of the Red-beds as ‘“Permotrias,” and 
states that ‘‘no definite line could be drawn between the Carbon- 
iferous and the Permian; or between the Permian and the Trias,’’! 
in that region. 
Mr. C. N. Gould writes me under recent date that he found, ina 
soft red sandstone not more than 100 feet above the base of the 
Red-beds or Cimarron series, eight miles west and three miles 
south of Blackwell, Oklahoma, or about sixteen miles south of 
Hunnewell, Sumner county, Kansas, a number of invertebrate 
shells. Mr. Gould states that the lower line of the Red-beds swings 
around farther to the east in the territory than it does in Kansas. 
In this paper no further attention will be given to the rocks 
above the Marion formation; and if the reader be interested in the 
higher formations he is referred to the papers already mentioned 
for fuller details. 
Greenwood and Butler Counties. 
While engaged in mapping the Cottonwood Falls sheet the 
Permian formations were followed into the northern part of Butler 
county, where they were not well exposed on the high prairie 
which forms the divide between the Cottonwood river valley on the 
north and the head waters of the Walnut and Whitewater rivers on 
the south. Consequently a section was sought that would show 
the stratigraphic details of these formations, and the line of the 
Missouri Pacific railroad, from Eureka to El Dorado, crossing the 
prominent ridge of the Flint Hills along the Greenwood—Butler 
county line? seemed to offer such a section, and this was studied. 
A paper giving a somewhat general account of the geology of this 
section was published in 1890 by Prof. L. C. Wooster. 8 
The writer was anxious in the first place to find the Cottonwood 
limestone, which, in his previous work, had been traced into the 
eastern part of Chase county, some thirty-five miles north of this 
Section, and then to study the overlying Permian formations. It 
was estimated that the horizon of the Cottonwood limestone would 
be found somewhere in the vicinity of Reece, Greenwood county,
