FLINT HILLS. 
The term ‘‘Flint Hills’’ is applied to the high uplands in 
western Chautauqua, Elk and Greenwood counties, and eastern 
Butler and Cowley counties. Lead ore and zine ore have 
been reported from many places throughout the Flint Hills” 
area. Some of these occurrences are known to the writer 
only by report—verbal or by letter. But a number of small 
and choice specimens of galena and blende have been exam- 
ined, reported to come from various places within the Flint 
Hills area. Mr. Allbright, of Winfield, has preserved speci- 
mens of galena nearly two inches in diameter and of zinc 
blende nearly three inches in diameter, which were obtained 
about twenty miles east of Winfield, or near the summit of 
the Flint Hills. Samples of both ores frequently have been 
sent to the University for identification, the writers stating 
that they came from this or that place within the Flint Hills 
area. 
The above are some of the localities to which attention has 
been called most prominently as possible sources of lead ore 
and zinc ore. It is probable that similar discoveries could 
be made in almost every township in the eastern fourth of 
the state. Apparently the shale beds contain vast quantities 
of these ores, and the limestone a small amount. But it is 
likewise probable that nowhere within the entire Coal Meas- 
ures of the state ores will ever be found in sufficient richness 
of deposit to make mining profitable. 
GALENA. 
The principal kinds of rock found in the Galena district are 
Coal Measure shales and sandstones, and limestones and flint, 
or chert of Mississippian age. 
Shales and Sandstones.—These Coal Measure rocks occur 
in two distinct ways: First, they are found here and there 
sparingly as outlying remnants or vestiges which erosion has 
not yet removed. Almost every one who has written on the 
subject of the geology of this area has called attention to this 
fact. Such remnants are found occasionally as far east as 
Green county, Missouri, implying that the Coal Measure rocks 
at one time extended at least that far east. Some authors have
