HARRISON COUNTY. 139 



The conglomerate ores of Harrison County may be divided into two di- 

 visions : 



1. An older and higher deposit, in which the conglomerate consists of 

 ferruginous pebbles from half an inch to an inch in diameter, sands, and 

 gravels, with occasional siliceous or quartz pebbles. This deposit breaks 

 with an even fracture and presents a firm, solid face. 



2. A newer deposit of conglomerate, in which the material consists chiefly 

 of a ferruginous gravel and sand, very closely held together by the same 

 cementing material. Pebbles of any size or material are usually absent in 

 this newer deposit. This deposit always lies close to the present stream beds 

 or within a very short distance above them. From its composition, looseness 

 of texture and materials, and its association with large quantities of gravel of 

 a texture similar to that of which it is formed, it has the general appearance 

 of being of recent origin, if, indeed, it is not at present actually in the course 

 of formation. As a source of iron these newer deposits are of no value 

 whatever. They might, however, probably be used in composition with coal 

 tar or asphaltum, or even alone, as a material for road making purposes. 



The older conglomerates are not, as a general thing, very rich in iron, and 

 are not likely to be used in the presence of the great quantities of better and 

 richer ores found throughout the county. The localities in Harrison County 

 m which these ores have their greatest development are: 



On the east side of the Clery Grillet and west side of the W. C. Duffield 

 headrights there is a ridge of the older conglomerate ore lying in an easterly 

 and westerly direction for nearly one hundred and fifty yards and having an 

 elevation of about sixteen feet. This ridge lies upon the north bank of a prong 

 of Potter's Creek, and the blocks into which the ore has been broken are 

 tilted in the direction of the creek bed. This condition is no doubt due to 

 the erosion of the underlying sand. These blocks are of large size, many of 

 them measuring over six feet in length. Farther down the main stream of 

 the same creek a deposit of the same grade of conglomerates occurs upon the 

 S. P. Hall headright. This deposit is somewhat more pebbly than that on 

 the Grillet headright and is associated with extensive deposits of gravel and 

 sand. 



Along the base of the mountain upon which Hynson's Springs are situated, 

 and the mountain lying about a mile west, conglomerate bowlders occur, and 

 on the west side of the hill near John Cole's house, on the Micajah Lindsay 

 headright, the same class of ore is to be found in blocks of large size. It is 

 also found upon the western sides of several of the small hills upon this sur- 

 vey in blocks, and is as a general thing a very poor pebbly conglomerate. 

 This region is tributary to Page Creek. Conglomerate also occurs along the 

 banks of Walnut Creek, in the James Chafiin headright.
