Cincinnati, which look very well, though, it is not as durable 

 a rock, as granite, or very hard limestone. 



This stone is frequently used for grind stones, whetstones, 

 6sc. and large quantities of these articles, are used in Ohio, 

 and begin to be carried beyond the limits of the State, for sale 

 to our neighbors. 



In some places, it is finer, and others are coarse. They are 

 very fine grained, near Waverly, but they are a pudding stone 

 in Jackson county. Where this rock is hard, and where it 

 once stood in a perpendicular mass, with a rivulet running off 

 it, caverns have been formed, in which the aborigines once 

 lived, and, before them, wild animals there, found a home, es- 

 pecially in winter. Such caves exist in Jackson, Lawrence, 

 and Gallia counties. Many such caverns were often used, as 

 cemeteries, in times long past. The small eagle, finds a place 

 of security, for itself and young ones, in the cavities, existing 

 in the perpendicular walls of this rock, fronting the Ohio river 

 and along it; — and hence, the name of the river, among the 

 Indians — Kiskepeela Seepee — Little-Eagle river. In some 

 places, the mass of sand, originally deposited, in this region, 

 by the ocean, for want of any cement in the mass, never be- 

 came a rock, but is sand still, in which, trees are imbedded, 

 but not petrified. Such a tree, was found on the high land, 

 near Marietta, in digging a well, (many years since) forty feet 

 below the surface. 



We suspect that it will eventually be ascertained, that the 

 whole sandstone formation northwest of the Ohio river, from 

 the Portage summit, south of it, dips towards the southeast, 

 about thirty feet to the mile : that inclination ends on that sum- 

 mit, which is the cause of that summit's location where it is, 

 nearer the lake than it is to the Ohio River. Should that be 

 ascertained to be the fact, it answers to a general law, notic- 

 ed in every thing, east of the Mississippi, which lies parallel 

 with the shore of the Atlantic ocean, and is inclined towards 

 it. Even the Alleghanies as a whole, obey the same law, and 

 the Atlantic rivers, originate in the most westwardly ridge of 

 that chain of mountains. The Avestern edges of the Allega-
