368 The American Geologist. December. 1902. 
The Fowler limestone,* occurring at various localities be- 
tween Fowlers Landing" and Burksville, usually is located 
higher up, above the steeper parts of the cliffs which are with- 
in easy reach of persons landing from a skiff. Moreover the 
Fowler limestone and the overlying Ordovician rock usually 
weather away more readily than the underlying section, so 
that they are less frequently exposed, and rarely form any con- 
spicuous part of the cliff' sections. 
The writer is therefore of the opinion that the major part 
of the rock designated as the Cumberland sandstone by Prof. 
N. S. Shaler must have been of Lorraine age, and if any part 
of the Richmond is to be included under this name this is due 
rather to accident than to the original intention of the author. 
The Richmond localities at Forbush and Little Cub creeks, 
and the Fowler limestone and overlying beds near Burksville 
are altogether too inconspicuous parts of the river sections 
a'ong the Cumberland to have given rise to this name. 
The writer is even more convinced that most of the beds 
in Casey, Marion, Boyle and Lincoln counties belong to the 
Lorraine. In the western part of Marion county, and in Nel- 
son county, less than 30 feet of Richmond beds have been 
identified in any section. The unfossiliferous beds in the 
vicinity of Lebanon belong to the Lorraine. This is also the 
horizon of the unfossiliferous beds at Moreland. 
On the eastern side of the anticline, in the vicinity of the 
Clinton outcrops, it is almost certain that both Richmond and 
Lorraine rocks have been included under the name of Cumber- 
land sandstone. Near Concord, east of Maysville on the Ohio 
river, the Richmond exceeds 164 feet in thickness. West of 
Spencer, on the railroad east of Mount Sterling, about 50 
miles southwest of Concord, the Richmond is about 62 feet 
thick. At the base, Streptelasnia msficiiin is common. Twelve 
feet above the base, Rhynchotrema capax and Stropliouiena 
plannmhona occur. Twenty feet below the top, Stroplioincna 
sulcata was found. The top of the beds containing the form 
of Plafystrophia lynx with a long hingeline occurs 46 feet be- 
neath the base of the Richmond. The intervening rock is al- 
most unfossiliferous. but stratigraphically belongs to the top
