thick, under which, separated by recemented iron ore, is a second bed of altered 

 greensand marl ten feet; under this, separated by thin iron seams, is a bed of 

 green marly clay, with pyrite, two feet; dark greensand marl, without pyrite, 

 six feet; indurated glauconitic clay, six inches; greensand marl, very dark 

 green when fresh, three feet, to sandy bottom of valley. (See section on

A similar outcrop on the same stream, some three miles southwest, near an 

 old mill, was seen by Mr. Moss, of Henderson, a companion for this trip, but 

 was not visited by the writer.

TIMBER. 



The total area of this county is 586,880 acres.* After deducting the amount 

 in field, fruit, and garden cultivation, 109,764 acres, and for barrens, town sites, 

 and streams, 68,159 acres, and for timber cut and in process of cutting by the 

 ten saw mills at work in the county, 58,422 acres, then the final remainder, 

 350,535 acres, would approximately represent the area of standing timber. 



The total value of this area of timber would be approximately represented 

 as follows: One-fourth, or 87,633 acres, suitable for lumber. The remain- 

 der, 262,904 acres of standing timber, if cut into cord wood, would probably 

 average 37^- cords per acre.
