408 GEOLOGY OF OHIO. 



derivable from the Devonian and Silurian limestones of north-western 

 Ohio, there are also many which must have had a more northern origin. 

 In the absence of positive data, the thickness of the Drift deposit at any 

 point in Auglaize county cannot be stated with certainty. Wells only 

 penetrate to the water-bearing gravel or sand, which is generally less 

 than fifty feet, although some have been known to go upward of seventy 

 feet before striking gravel or sand in sufficient quantity to furnish a con- 

 stant supply of water. The average thickness, however, is not believed 

 to be much greater or less than in the eastern half of Allen county. The 

 lack of rock exposure, while it indicates a greater accumulation of Drift, 

 may be due to the absence of large streams capable of eroding the deposit 

 to the rock. 



MATERIAL RESOURCES. 



It is evident that the material development of Auglaize county will 

 not be from the geological stand-point, except so far as the materials of 

 the Drift may be made to subserve the comfort and convenience of its 

 inhabitants. These materials themselves have a geological origin, and 

 give character to the soil. Thus geology antedates agriculture ; and in that 

 sense even the agricultural resources of the county may be said to be of a 

 geological origin. Aside from this, however, the Drift of the county is 

 rendered abundantly useful. It supplies an excellent clay every way 

 suited for the manufacture of brick, tiling, and pottery. The gravel of 

 the ridges which cross the county, wherever it is revealed, is made to 

 subserve the purposes of road-making, though not to that extent that 

 its proximity and the ease with which good roads can be made by its 

 use would indicate and demand. 



The following establishments for the manufacture of brick and tiling 

 were met with in the survey of the county. There may be others :
