Number 2 seems to be a phase of the Cheyenne, and is the 
only instance noticed outside of the Belvidere locaHty. It 
occurs in a wash-out about three-fourths of a mile east of 
Mr. Osborne's house. The leaves in No. 5 were found near a 
point on the hill above the wash-out. The rest of the section 
is best exposed in the canyon issuing from the Natural Corral 
one mile west of Mr. Osborne's. 
The characters of the matrix of the two fossiliferous ledges. 
No.'s 4 and 10, are very different. No. 4 is a bluish limestone 
of the kind so common at Belvidere and in Clark county and 
differs from anything seen elsewhere north of the Arkansas 
river. No. 10 on the contrary is in color and lithological ap- 
pearance very like the sandstone boulders which, scattered 
over the hills of Saline county, contain the Mentor fossils or 
dicotyledenous leaves. It dififers in the fact of forming heavy 
ledges and in this regard has the general appearance of the 
Dakota.
