this feature being much more pronounced and of greater extent 
in southern Kentucky than in Ohio and Indiana. In fact, some 
of the lower portions of this series may with truth be called sand- 
stones. 
Observations of Dr. John Locke at West Union; Upper Hudson.— 
The locality is twelve miles a little east of south of Elk Horn 
creek, near a house known as Treber’s at the time of Locke’s 
report (Geol. Surv. Ohio, 1838, p. 246, and plate 6), in the bed of 
Lick Run. It is about four miles northeast of West Union, as 
nearly as can be determined from the report. Mere, about 
fifty-five feet below the level of the Clinton, for a distance of 
400 feet, wave marks occur in the upper Cincinnati group beds, 
with crests two to three feet apart, and two to three inches 
above the troughs. According to Locke they may be traced at 
about the same horizon for miles. 
Observations of Professor Orton.—\n Vol. 1. of the Ohio Survey 
report, page 377, Prof. Orton mentions that Locke noted the 
wave-marked layers in the upper beds of the Cincinnati group, 
and then states that they are even more characteristic of the 
lower beds (the Lower Hudson of Kentucky reports) as shown 
in the river quarries of Cincinnati, or in the 100 feet that are 
there exposed. These wave-marked layers are said in every case 
to be overlain by shales.

West Covington, Kentucky (Lower Hudson, or Utica of Ulrich). 
—Opposite Cincinnati, halfway between the Chesapeake and 
Ohio and the Cincinnati Southern railway bridges, opposite house 
No. 31, along the road skirting the river front, nearly at the 
top of the section exposed along the Ohio river is a well strati- 
fied, sandy-looking limestone layer, in places almost two feet 
thick, which can readily be traced for a considerable distance 
along the river front. Over this lies a layer composed chiefly of 
coarse crinoidal remains but containing also many bryozoan frag- 
ments, and some brachiopods. The crinoidal layer is about 
twenty inches thick. Its chief interest consists in the fact that
