378 GEOLOGY OF OHIO. 



graphical horizon must be nearly or quite the same. At this place it 

 can also be profitably worked for a building stone when the settlement 

 of the county shall have progressed so far as to demand a cut-stone of 

 such quality. At the present time it is used somewhat for foundations ; 

 but the abundance of stone generally throughout the county retards the 

 special development of superior qualities. The following section was 

 taken at this place, a portion of it being from the N. E. \ section 12, 

 Liberty township : 



Downward Section of the Watekltme at Pohtage, Wood County. 



No. 1. Soft, drab, somewhat vesicular, weathering a huff color ; 

 beds, six to sixteen inches ; texture generally homoge- 

 neous, similar to the magnesian and harsh, thick beds 



of the Lower Corniferous 2 ft. 4 in. 



" 2 Harder, crystalline, with a darker color, showing some 

 bituminous films, which, on fracture, appear as black, 

 horizontal streaks. In this "member there is a tendency 

 to an oolitic structure, seen sometimes in patches, or 

 in beds horizontally continuous, with a thickness of a 

 quarter of an inch to three inches ; beds three to eight 

 inches 2 |'

This section is displayed on the land of William Sargent. The dip is 

 toward the south and south-east. At the crossing of the road between 

 the two townships it is ten to fifteen degrees south-east. The land rises 

 toward the north and north west, caused by the appearance of the 

 Niagara. East of the bridge about forty rods, thin and slaty beds are 

 seen in the river, some of which are so bituminous as to burn like coal. 

 Twenty rods further down, on land of Mrs. J. L. Roland, the rock appears 

 hard, crystalline, dark drab, almost brecciated, yet in regular beds of 

 sixteen to twenty inches ; dip, south-west. This probably overlies the 

 layers of the foregoing section, since, the dip continuing the same, the 

 soft, magnesian, drab beds (No. 1 of the section) appear with a thickness 

 of fourteen to twenty inches, affording opportunities for a profitable 

 quarry. 



Near Mill Grove, in Perry township, the Waterlime in loose pieces 

 has been burned for quicklime on the farm of Winfield DeWitt. It also 

 appears in regular beds of two to four inches in the East Branch of the 

 Portage, at the village, and again in the McCutchenville road, N. E. \ 

 section 9, in similar layers ; also further south, in the same section, in 

 thick beds. In the S. W. \ section 17, Mr. Daniel Pclton obtains good 

 flagging stone from the Waterlime, one to three inches in thickness. On
