318 GEOLOGY OF OHIO. 



of a little stream (Jennings's Creek), and shows the usual features of the 

 formation. It is thin-bedded, but rather close-grained and hard, in wavy- 

 bedding, showing some bituminous deposits. This lime is very much 

 darker than that at Streughn, but averages seventy pounds per bushel, 

 selling at the same price. It resembles the quicklime from the same 

 formation made at Lima, in Allen county. The bottom of this creek is 

 rocky for a mile and a quarter: The stone occurs on the land of Joseph 

 Feierbach, F. W. Courts, and Mat. Boche. 



At Delphos, S. W. £ section 24, Washington, the Waterlime has for- 

 merly been taken from the bed of Jennings's Creek, and burned for quick- 

 lime by L. G-. Roebuch. The stone is rather rough, and in thick, some- 

 what cavernous beds, with considerable calcite. Thinner beds also occur. 



In Union township (N. W. \ section 8) the quarry of B. Bohnert & 

 Co. is in a gentle anticlinal in the Waterlime, or in that member of the 

 Lower Silurian which is quarried at Streughn. It may be some other 

 member of the Lower Helderberg. The exposure is not sufficient in the 

 county to identify, without doubt, its horizon. It is hard, light-drab, yet 

 often porous, in beds of two to six inches, which run irregularly and 

 break into angular pieces of all sizes. Although its color is a light drab, 

 yet it has some spots almost a cream-color. It is occasionally variegated 

 somewhat with blue, and looks then very much like Niagara. No fossils 

 are visible except a fine Favosites coral, a small Orthoceras, Atrypa sul- 

 cata, and Leperditia alta. (?) It shows about eight feet. 



At the quarry the surface of the rock is not glaciated. The soil is not 

 more than eighteen inches, and of a black color, and the Drift is almost 

 wanting. The rock is rounded and smoothed rather by the slow action 

 of water and air than by ice. 



A gray, close-grained limestone, that in hand-samples takes a good 

 polish, is met also on the land of Thomas P. Johnson, S. W. J, section 17, 

 Union, in surface exposure. It is in the Waterlime. On the N. W. J, 

 section 4, Ridge, on the land of the heirs of Wm. Palmer, stone was 

 struck in digging a ditch. It is a drab-gray, crystalline Waterlime, in 

 beds of four to six inches, or perhaps thicker. It has not been opened to 

 any extent. 



The Drift. — The only exception to the generally unstratified and unas- 

 sorted composition of the Drift in Van Wert county, is seen in the Van 

 Wert ridge, which crossos the county through Tully, Pleasant, Ridge, 

 and Washington townships. The cities of Van Wert and Delphos are 

 situated on it. It consists generally of gravel and sand, in varied and 

 oblique stratification. In a few places it has been penetrated to the 

 depth of over thirty feet without meeting much gravel. In those cases
