Kentucky extension. Inthe report on Garrard county the state- 
ment is made that some ‘‘shot”’ iron ore comes from some place 
in the Crab Orchard shales, but it was not found. Red hematite 
iron ore, the odlitic variety, is mentioned from northeastern Clark 
and Montgomery counties. The odlitic iron ore is well charac- 
terized in Bath county and is definitely located there about 
four feet above the wave-marked layer and about 23 feet above 
the base of the Clinton. It varies in thickness from a few inches 
on the Montgomery line to nearly three feet on the eastern side 
of the county. In Fleming county it is sometimes absent, and 
sometimes appears at its proper horizon, but very much dimin- 
ished in thickness. It is seen also in Lewis county, and is well 
shown at various localities in Ohio, where it also occurs only 
along the eastern side of the anticlinal axis. Its occurrence 
usually a short distance above the wave-marked layer may be of 
some significance. The fact that the wave-marked layers and 
the odlitic ore in both Ohio and Kentucky are confined to the 
eastern side of the axis is certainly very suggestive as to the 
conditions under which the Clinton was deposited there. 
Chert is found in the Clinton in Henry county, the horizon 
not stated. In Nelson it occurs towards the top of the Clinton. 
In Marion county it is common. Its best development however 
seems to be in the northeastern counties, in Bath, Fleming, and 
Mason, where it occurs in the heavy limestones toward the base 
of the Clinton. This same horizon it occupies in Ohio. In Bath 
county, the general thickening of these heavy beds eastward is 
noted. ' 
For the sake of completeness, two peculiar occurrences should 
be noted, which deserve fuller study in the field. Near Freder- 
icktown, on the western side of Washington county, several 
inches of conglomerate occupy a position just underneath the 
heavy limestones of the section, presumed to be the Niagara. 
This would place it at the top of the Clinton. The conglomerate 
was composed of fragments of iron ore, probably the remains of 
the Clinton iron ore beds, cemented in a sandy shale. This con- 
glomerate probably once extended over the entire country. In
