HAWORTH AND BENNETT.| General Stratigraphy. 105 
stone occupies almost the entire surface from its outcropping 
line on the east to the Oread on the west, with the Lawrence 
shales here and there forming a thin covering of variable 
thickness. 
Characteristics.—The Stanton limestone in most respects is 
quite similar to others in this part of the state. It is well 
bedded, yielding thin individual layers, in most places sepa- 
rated by thin shale partings. At the stone-quarry at Benedict, 
however, some of the limestone layers are from 6 to 8 feet 
thick. Elsewhere one of these shale partings assumes con- 
siderable importance and becomes a rich, bituminous shale 
from 4 to 8 feet thick. In the vicinity of Princeton, for ex- 
ample, along the Santa Fe track at a crossing of one of the 
branches of the Pottawatomie, some one apparently has mis- 
taken this jet-black shale for coal and has mined quite a vol- 
ume of it, only to leave it lying on the ground unused. At 
Ottawa the same shale-bed has a thickness of 7 feet and pre- 
serves its bituminous character. Good exposures of this bi- 
tuminous shale can be seen at Eudora, in Douglas county, and 
at Linwood, in Leavenworth county.

Le Roy Shales. 
The name Le Roy shales is used here to designate the shale 
first above the Stanton limestone and first below the Kickapoo 
limestone. In 1894 Haworth and Kirk recognized them in 
their section along the Neosho river. Later they were sup- 
posed to be correlated with the Lawrence shales so well ex- 
posed farther north. In those days of imperfect correlation it 
was difficult to determine just what were their equivalents 
north and south. We are now able to say that they have a 
sufficient existence to warrant a separate name. 
Thickness.—The Le Roy shales vary in thickness from 60 
to 100 feet. They are about 100 feet thick in the vicinity of 
Le Roy and to the south. From here northward they gradu- 
ally decrease to the west of Ottawa and then increase to 100 
feet in the vicinity of Lawrence, and gradually grow thinner 
to the northward to about 60 feet. 
Area.—The Le Roy shales occupy a zone along the dip slope 
of the Stanton limestone and extend from the south side of
