HAWORTH AND BENNETT.| General Stratigraphy. 93 
Characteristics.—The Mound Valley limestone in all of its 
essential properties is about the same as the Bethany Falls 
limestone already described. The two are so similar that one 
would be unsafe in trying to distinguish the difference between 
them by mere physical properties. 
Fauna.—See Doctor Beede’s chart, plate XLII. 
Galesburg Shales.4 
The name Galesburg shales was proposed by Adams to desig- 
nate, as he put it, “the rocks occupying the interval between 
the Hertha limestone and the Dennis limestone.” As has al- 
ready been shown, Adams in some way overlooked the exist- 
ence of the Mound Valley limestone, which separates the 
shale-bed he referred to into two parts. For the shales below 
the Mound Valley limestone we have already accepted Schra- 
der’s name, Ladore shales. It is here proposed to retain the 
name Galesburg shales for those lying above the Mound Valley 
limestone and below the Dennis limestone. 
Thickness.—In the southern part of the state these shales 
reach a maximum thickness of fully 60 feet along the bluff 
lines of Big creek in northwestern Labette county. To the 
northeast they gradually grow thinner. West of Uniontown 
two miles they are about 8 feet thick, and at Kansas City they 
are not more than 5 or 6 feet in thickness. | 
Area.—The area occupied by the Galesburg shales neces- 
sarily is triangular in outline, with the widest part towards 
the south. On account of the peculiar topographic properties 
of the surface at no place do they cover a wide stretch of sur- 
face, but are known principally in the bluff lines and scarp 
walls. From the vicinity of Uniontown northward they are 
known only as the parting walls between the thin beds of lime- 
stone. 
Characteristics.—The Galesburg shales have no distinguish- 
ing characteristics. They are practically the same as the La- 
dore shales and others in this part of the state. They are clay 
shales to a great extent, here and there changing to arenaceous 
and bituminous. 
Dennis Limestone. 
Adams used the name Dennis limestone to designate a lime- 
stone formation immediately underlying the little way station
