The most of the county is poorly supplied with building stone. This 

 necessary article is imported from Logan county, where the Onondaga 

 quarries at Middleburg afford a .good stone, from the quarries in the 

 Hamilton, at Marion, in Marion county, and from the same at Delaware. 

 The quarries in the limestones of the Devonian, in the south-eastern 

 part of the county, would probably be better patronized if better roads 

 intersected that section, and if the quarries themselves were energet- 

 ically developed. Not much lime is made in the county, the kiln of 

 Thompson and Brown, in Mill Creek township, doing more than all 

 others united. A kiln has recently been opened near Unionville, by 

 Sager and Robinson, for burning the Waterlime, and at Plain City the 

 beds of the Delhi stone are burned by William Lamb, the stone being 

 hauled from Dublin, on the Scioto River. William Bales burns a little 

 lime in the extreme western angle of Allen township, from loose pieces 

 of limestone taken from gravel banks and from the bottom of Darby 

 Creek. 



The Drift clays, however, are freely used in the manufacture of red 

 brick and tile. The following list embraces such brick and tile yards as 

 were noticed in the survey of the county :
