the crest of the Flint Hills, as is shown in the picture of the mas 
sive ledge four feet thick south of the railroad at the western cut. 
The upper part of the shaly limestones—No. 14—are of bluish and 
yellowish color and contain great numbers of fossils, as does the 
similar zone described on Elm creek west of Council Grove,! and 
in the railroad cut east of Grand Summit, Cowley county. The 
upper layer of the limestone and flint with the fossiliferous zone of 
the shaly limestones is nicely shown in the western railroad ‘cut, 
about a half mile east of Summit station; the base of the lower 
limestone and flint in the cut immediately west of the trestle, and 
the middle part of the sub-formation in the intervening cuts. 
In the railroad cut, just west of the trestle, the upper part of the 
Neosho formation is admirably shown, the top of the cut being in 
the base of the Strong flint. The upper part of the Neosho is com- 
posed of a zone of yellowish shales containing specimens of Derédya, 
which are apparently nearer D. mu/tistriata (M. and H.) Pros. than 
D. crassa (M. and H.) H. and C., and a few other species similar to 
the zone of yellowish shales exposed at the top of the Neosho 
formation on the Crusher Hill west of Strong City.? 
In the railroad cut 2,000 feet east of the trestle are grayish to 
yellowish shaly limestones-—No. r1—in which specimens of Pseudo- 
monotis Hawni (M. and H.) are common. The following species 
were collected in this cut:

This zone is Re near bie muadle of the Neosho 
formation. 
East of this cut the greater part of the surface is covered by soil, 
and most of the railroad cuts are shallow so that the base of the 
Neosho formation was not accurately determined. Again, appa- 
rently, the Cottonwood limestone which forms such striking mas 
sive outcrops to the north, in Chase and Lyon counties, has lost its 
massive structure and does not form conspicuous outcrops in the 
western central part of Greenwood county.
