There is a slight dip to the north. Near here Andrew Dilz burns lime 
from these beds, the lime being of a bluish-ashen color, and having a 
noticeable hydraulic quality. No. 3 has considerable thickness, and 
graduates below into the Hamilton. Another quarry in this stone is 
mentioned under Geology of Henry County. That of Wm. Wileman is 
in the same beds, situated in the Maumee River, near the Henry county 
line. | 
The Hamilton.—In the N. E. 3 section 17, Defiance, on the land of 
Michael Humbert, is a quarry in the Auglaize River, in a crystalline, 
vesicular, bluish-gray limestone, that contains considerable chert be- 
tween the bedding. It holds indistinct cyathophylloid corals. Also, in 
the chert may be seen the cells of a coarse Favosites. One bed is about 
a foot thick. About three feet can be made out. This stone is probably 
the downward continuation of No. 3 of the last section, although there 
is an unexposed distance of about two miles between them. How much 
of this belongs to the Hamilton, or whether anything below No. 1 of the 
last section should be included with the Tully, it is not possible to say. 
It is true, however, that No. 1 of the last section above is the only part 
that resembles strongly the beds referred to the same horizon seen in 
Marion and Delaware counties: 
On section 17, Defiance, is the quarry of Town Newton. Stone is taken 
out there for the Paulding Furnace. The color, grain, and all the exter- 
nal characters of this stone resemble those of the stone quarried at San- 
dusky and used in the basement of the court-house at Defiance. The 
dip is north or north-east. Further south in Paulding county are other 
exposures of the same stone, likewise situated in the valley of the Au- 
glaize. The reader may consult the report on that county for remarks 
on the supposed equivalents of these limestones in New York. 
On section 24. Delaware, Elias Bruner has diseovered a stone in the 
bottoms of the Maumee which. belongs to the Corniferous limestone, 7. e¢., 
to the fossiliferous, light-colored beds that first underlie the blue lime-
