360 GEOLOGY OF OHIO. 
a dark drab color, with darker mottlings of blue and purple, and slightly 
porous. It weathers a buff. The surfaces are very often roughened by 
small angular prominences which fit. into corresponding depressions in 
the superimposed layer, forming the peculiar structure known as suture- 
jounted. The beds here lie nearly horizontal, although at other places 
near they show a slight dip both south, south-east, and south-west. De- 
scending the creek from Pressnell and Shirden’s quarry, the same charac- 
ters are seen in the rock, which shows constant surface exposure to its 
junction with the Blanchard. Two or three short anticlinals cccur in 
the bedding within that interval, and the beds are often glacier-scratched 
in a direction south 40° west. The bed of the creek lies on the surface 
of the rock, without having made any sensible excavation. Further up 
the creek aré the quarries of Mr. Chris. Neucer, on land of Dr. B. Raw- 
son, which also supplies stone for all the uses to which the Niagara is 
adapted, and of Mr. HE. P. Philips, the latter on the N. W.4,S. H. 4+ sec- 
tion 30, of Findlay township, and embracing also a few beds of the over- 
lying Waterlime. 
S. E. 4 section 18, Findlay township. In the bed of Lye Creek the 
Niagara appears in thick beds, and has been burned for quicklime by 
Mr. Isaac Harshy. Along this creek the Niagara may be seen on section 
10, Jackson township, where it is in porous beds of three inches, rusty 
and shattered from exposure; and on S. EH. 4 section 33, Marion town- 
ship, where the bedding is the same, showing some blue and gray on 
fracture, and frequently to the junction of the creek with the Blanchard. 
It also was observed on S. W. } section 27, Marion township, on land of 
Samuel Hssex, in the bottom of a ditch, and in the 8. W. 4 section 33, iu 
a ditch by the side of the road. 
In the Blanchard it is quarried in sections 12 nae 1, Amanda town- 
ship, where it is gray and vesicular. After it has been weathered a 
short time it acquires a greenish tinge, and also becomes firmer. A spe- 
cies of Jllenus was met with here. On section 21, Marion township, it 
lies in massive gray beds. Mr. Allen Wiseley has opened it in the 
Blanchard on N. W. + section 23, and it is abundantly exposed on section 
16, both of the same township. Near Findlay it is quarried by Mr. 
Squire Carlin and by Mr. William Pilcher. Under the highway over 
the Blanchard at Findlay it has a characteristic surface exposure, where 
the current of the river has washed away the left bank so as to uncover 
a beautiful exhibition of glacial marks. 
In the township of Cass the Niagara is wrought for lime and for foun- 
dations by Mr. John Frank, on the S. W. + section 4. Beds have here a 
thickness of three to six inches; loose and vesicular.
