seems to be spread more largely through the overlying Onondaga in 
Wood county than in Sandusky or in Delaware county. In both of these 
counties, as well as in Paulding, the Oriskany merges into the Onondaga 
by insensible changes. In Paulding and in Sandusky there is a consid- 
erable thickness of: a soft magnesian limestone in heavy beds, excellent 
for cut-stone, lying below the Oriskany, having no arenaceous tendency. 
These beds have very much the aspect of the recognized Onondaga, or 
Lower Corniferous, and have been regarded as belonging to that forma- 
tion, but are somewhat more bituminous. Their actual place in the 
series throws them, however, into the Waterlime, and they have exactly 
the characters of that phase of the Waterlime which has been described 
as “Phase No. 2” in reports on Ottawa and Wood counties. The quarry 
at Charloe is in these beds, their thickness being about six feet. 
The Waterlime.—This limestone affords many characteristic and valua- 
ble exposures in the bed of the Auglaize River above Charloe. It ap- 
pears S. EH. $+ see. 21, Brown, one-fourth of a mile above the mouth of the 
Little Auglaize, between the farms of Oliver Young and H. Harmon, on 
opposite sides of the river. It is here of a light blue or blue-drab color, 
in beds of four to eight inches; hard, yet porous, with Leperditia, and 
makes excellent lime. Some of this stone is crystalline, like the Van 
Wert county Waterlime, and some is dark drab and rough. The Water- 
lime also appears in the Auglaize at the mouth of the Little Auglaize, 
showing the characteristic fossil, Leperditia alta; beds thin, but finely 
crystalline. In the N. EH. + sec. 34, it is a fine-grained yet magnesian 
stone, which under the hammer emits a bituminous odor, and is soft, 
like the Onondaga beds of the Corniferous. It here shows in rather 
heavy beds, which in a cross section have a curly internal structure, 
with bituminous films. Yet these thick layers are intermingled vari- 
ously with thinner, fine-grained drab layers, that show the characters of ° 
“Phase No. 3” of Ottawa county. In section 35 the bed of the Auglaize 
is on the fine-grained drab beds of the Waterlime, which have been a 
little worked for local use. Section 1, in Washington, shows Waterlime 
of the same kind. It is also exposed in section 29, same township, in 
the creek, where it is quarried. 3 
General Section of the Rocks in Defiance and Paulding Counties. — In* the 
progress of the survey of Delaware county some evidence was obtained 
of the Hamilton age of the whole of the blue limestone of that county, 
but not such as placed such an opinion beyond the limit of doubt. Ham- 
ilton fossils are found in it in various places. The same is true of its 
exposures in Marion and Seneca counties, and at Bellevue, in Sandusky 
county. But in Paulding county the closest attention was paid to the
