HAWORTH AND BENNETT.| General Stratigraphy. 83: 
first used in volume III, page 36, of this series of reports, sug- 
gested by Adams while the manuscript was in preparation. 
Previously Haworth and Kirk" had suggested the name Lane- 
ville shales in their preliminary report on the geological sec- 
tion along the Neosho river. Later the term Laneville was. 
dropped when the formations named in the section made in 
1894 were first correlated, as explained earlier in these pages. 
Thickness.—The Labette shales vary from 20 to 60 feet in 
thickness. On the north side of the Marmaton river near 
Fort Scott they are not more than 20 feet thick. West of 
Fort Scott from two to three miles they measure fully 60 feet 
in thickness. These extremes are the greatest variations ob- 
served anywhere in the state. 
Area.—The Labette shales cover a narrow zone or belt ly- 
ing within the outcropping lines of the overlying Pawnee and 
the underlying Fort Scott limestone. It is rarely more than a 
few miles in width and in some places narrows to a few yards. 
Its position in a northeast-southwest line is well represented 
on the surface map, plate Vila, VIIb and VIIc. 
Fauna.—The Labette shales have numerous calcareous con-. 
cretions and streaks and a good supply of invertebrate fossils 
associated with them. For a complete list see Doctor Beede’s 
chart, plate XLII. 
Pawnee Limestone.14 
The name Pawnee limestone was given by Professor Swal- 
low to the limestone first overlying the Labette shales, largely 
developed along Pawnee creek in Bourbon county. 
Thickness.—The Pawnee limestone is from 8 to 52 feet in 
thickness, the thinner places being undoubtedly where the 
upper part has been worn away by erosive processes. How- 
ever, it is a limestone which varies in thickness from place 
to place more than some of the other Kansas limestones. 
Area.—The Pawnee limestone is exposed along a narrow 
zone from the south line of the state west of Chetopa to the 
east line of the state in the vicinity of Fulton, as shown on the 
accompanying map. It does not cover a very wide surface, 
probably two miles representing the greatest space from which 
the overlying shales have been washed away. At different
