elusion is based is quite convincing, and the date — Pleistocene — as- 
signed for the uplifting seems probable. 
In describing the stratigraphic series, which embraces the forma- 
tions from lowest Ordovician (Chazy) to the Lower Coal Measures 
(Pottsville), some new names of a local character are now introduced 
for the first time in Kentucky geology. 
These in ascending order are: "Highbridge limestone"; correlated 
Avith the Chazy and Birdseye of New York, following Linney, though 
there is a disposition to ignore the importance of Linney's distinction 
here. The thickness, ten feet, as assigned to the whole Birdsaye, is too 
low. It should be 130 feet. 
''Lexitigton limestone" equals "Trenton" of the Kentucky Reports. 
"Flanagan chert"' equals "Hudson chert" of the Kentucky Reports. 
" Winchester limestofje" equals "Lower Hudson" of the Kentucky Re- 
ports. 
"Garrard sandstone" equals "M. Hudson sandstone" of the Kentucky 
Reports. 
"■'Richniond shale" equals "Upper Hudson sandstone" of the Ken- 
tucky Reports. 
This term refers to Richmond, Indiana, not Richmond, Kentucky, 
as one would naturally think, if it were not for the explanation that it 
is adopted upon the authority of Mr. E. O. Ulrich, who has used the 
term as descriptive of this portion of the series in Indiana. 
" Panola formation" equals U. Silurian and Corniferous of the Ken- 
tucky Reports. 
" Irvitie for/nation " correlated with Neocene deposits. This forma- 
tion was never noted in the Kentucky reports. 
The formations between the Panola Formation and Irvine Forma- 
tion are given for the most part the same names as those in Virginia 
and Tennessee with which they are correlated; namely — 
"Chattanooga shale' equals "Ohio black shale" of Kentucky Re- 
ports. 
"Waverly shale" ('M\o\)\.ed from Ohio) equals "Waverly shale and 
sandstone" of Kentuckv Reports. 
^'Neivinati limestone" ecjuaJs ".St, Louis limestone" of Kentucky Re- 
]3i)rts. 
"Pennington shale" ecjuals "Chester ?" of the Kentucky Reports. 
"Lee formation" with its sandston:^ lenses equals "Coal Measure con- 
glomerate" or "Rockcastle Series" of the Kentucky Reports. 
The mineral resources of this area are not great, hence treatment 
of the economic geology is brief. Some coal occurs in the south- 
eastern corner of the quadrangle. Limestones for building purposes 
and road metal are well distributed over the area: — the best building 
•stones being those from the Kentucky river cliflfs, — the so-called "Ken- 
tucky River marble." Brick and pottery clay arc widely distributed: 
the best being near Waco — the "Waco clays." These are considered 
residuals from the weathering of the "Panola formation." Is it not 
rather likely that they are the "Neocene clays" of the "Irvine Forma- 
lion?" Proper mention is made of the "phosphate deposits" and their
