consequently a careful examination of the rocks was begun near 
this town, nine miles south of west of Eureka. This village is sit- 
uated on the northern side of the Spring creek valley on the Mis- 
souri Pacific railroad, 137 feet above Eureka, to the west of which 
is the fairly steep eastern slope of the Flint Hills, affording natural 
exposures of the rocks and in, addition the railroad cuts furnish 
several excellent sections, especially toward the crest of the ridge.

CREST OF THE FLINT HILLS.

15. Massive light gray limestone and flint or chert.! This ro==390* 
forms a conspicuous stratum near the eastern crest of 
the hills, as shown in the picture. Well exposed in 
the railroad cut at the eastern crest of the hills. 
14. Bluish and yellowish shaly limestones with abundant 29380 
fossils. Lower part maroon, bluish and yellowish 
calcareous shales. 
13. Massive stratum of light gray limestone, containing a 11==351 
large amount of flint in layers. 
(Nos. 13, 14, and 15 are Strong flint. ) 
12. Upper part yellowish shales, containing abundant 65==340 
specimens of Derbya; top of the Meosho formation. 
Greater part maroon, calcareous shales, well exposed 
in the lower part of the railroad cut west of the trestle, 
where they are capped by the lower part of the flint. 
t1. Grayish to yellowish shaly limestones, in railroad cut 25-275 
2000 feet east of the trestle, containing Pseudomonotis, 
Lower part of this zone covered. 
to. Rough, jagged limestone, containing iron concretions 2-250 
2 to 2% feet thick.

1 The name ‘flint’? has been so universally used for the silicious deposits of the 
iene Permian that it seems better to use it here rather than the more precise term 
chert. 
2 Prof. Wooster gave the dip as 20 feet per mile to the west, along the line of this 
railroad (Op. cit., p. 10). and if this estimate be correct it will add 100 feet or more to the 
thickness of the rocks in the above section. Ina letter Prof. Wooster states that the 
average dip at Kureka is about 12 feet per mile to the southwest.
