Building Stone. There is the greatest abundance of good building 

 >tone in this county, so distributed as to make it of easy access to all its 

 citizens. All the formations are quarried. In Pleasant Valley a num- 

 ber of good quarries are opened in the Cincinnati group of rocks. These 

 quarries arc in the brows of the hills, on either side. The stone ob- 

 tained is sufficiently thick -bedded and compact to make a good building 

 stone. It has a dry, dusty, kiln dried appearance. Several farm houses 

 arc built of this material in the valley. So far it seems to answer well 

 for farm uses, without exhibiting a tendency to disintegrate. Tlie best 

 of it would. I think, be uns.ife for massive and long enduring masonry, 

 but for light masonry it seems to answer well : and its convenience of 

 access, and the ease with which it can be quarried, will always cause its 

 outcrops to be kept open and worked. The abundance of better build- 

 ing material in most parts of the county doubtless prevents its exten- 

 sive use in other places, where it could be easily obtained. 



The Blue limestone outcrops, along the north branch of Fever river, 

 a fiord some good building stone. This is a light-gray limestone, rather 

 thin-bedded, and of enduring properties. The outcrop at Duuleith also 

 splits into a conveniently handled stone, and is used extensively for 

 economical purpi 



The massive ledges, exposures, and natural outcrops of the Niagara 

 and Galena limestone along nearly all the streams, in the brows of all 

 the bluffs and hills, and in all those parts of the county where these 

 heavy deposits are the bed rocks, furnish an inexhaustible supply of a 

 coarse, enduring, valuable stone, suitable for all sorts of heavy masonry, 

 such as bridge piers and abutments, foundations, cellar walls, and even 

 public buildings and private residences. They require considerable 

 dressing for these latter purposes, but when dressed into good shape, 

 their rich, warm, brown and cream colors, and the fact that they season 

 into almost the hardness of a granite, and have an enduring, solid, sub- 

 stantial appearance, makes them prominent among the materials of eco- 

 nomical value in the county. 



Lime. We know not to what extent lime is burned in the county. 

 The abundance of timber and the abundance of good inagnesiau lime- 

 >toiie. afford all the facilities for manufacturing large quantities of a 

 good, coarse, strong lime. 



Clays and Sand. The clays associated with the Cincinnati shales are 

 sufficiently pure to furnish a potters' clay, good for the manufacture of 

 common crockery ware. At Elizabeth I noticed several outcrops of this 

 potters' clay in some of the streets and lots of the village. Four or five
