few feet. At a point one mile east the well of Mr. Lawrence Sader, sit- 
uated at his brick and tile establishment, met the Niagara after passing ) 
through fourteen feet of brown and blue clay. | 
In Portage township the Niagara may be seen in section 6, on Mr. 
Fuet’s land, and at Portage, N. W. 4 section 7. At the latter place it is 
slightly quarried near the public school-house. A well dug at Portage, 
on Mr. Louis Dinest’s land, happened to strike a crevice in the rock two 
feet in width. The overlying Drift was eighteen inches. This crevice, 
upon removing the Drift, furnished water at the depth of six and a half 
feet from the surface. 
The Salina.—On the eastern slope of the Niagara anticlinal, in Ottawa 
and Sandusky counties, the Salina is met with, but in a very reduced 
condition. It is represented by a green shale, which is not more than a 
foot in thickness, and is altogether wanting south of Sandusky county. 
In the north-eastern part of Ottawa county it has a thickness of at least 
thirty feet, and contains the white gypsum exported from Sandusky. In 
Wood county the junction of the Niagara and Waterlime has not been 
observed, and nothing is known concerning the existence of the Salina 
west of the Niagara anticlinal. . 
The Waterlume in Wood county has the three lithological phases de- 
scribed in giving the geology of Ottawa county. 
ist. It is a coarse, brecciated limestone, without distinct bedding or 
stratification; often massive; sometimes vesiculated, even cavernous; of 
a dull gray or drab-gray color, and almost destitute of fossils. In this 
condition of the Waterlime there are small, irregular patches of fine, 
hard, and close-grained rock, with thin laminations of alternating light 
and dark drab, running in wavy lines sometimes quite perpendicularly, 
but often at angles constantly changing. Such rock is heterogeneously 
mingled with loose-grained, vesicular rock, of a lighter color, which, by 
crumbling under the influence of the weather, gives the whole mass a 
cavernous appearance. 
2d. It is a coarse but even-grained, thick-bedded, and magnesian lime- 
stone, of a dirty buff color, soft and easily wrought; a very useful stone 
for building where it can be found in sufficient quantities. 
3d. It appears very frequently as a thin-bedded, drab, close-grained 
limestone, the layers of which are uniformly separated by bituminous 
films. This character of the Waterlime is subject to sudden and inex- 
plicable changes of dip. The beds, which are usually about three inches 
thick, are sometimes not more than half an inch. It most frequently 
shows the characteristic fossil Leperditia alta, although it has also been 
found in No.1. No.2 has as yet afforded no fossils, so far as known.
