The third or Eastern Field is about seven miles north of Jefferson, and 

 includes that region lying around and including Berry's Hill in the northern 

 part of the county. This ore field embraces the John Kettrell, Isaac R. 

 Jones, J. W. Duncan, N. McHanks, Druery Richardson, north half of W. W. 

 Giddens, northeast quarter of the Jno. A. McKinney, west half of the W. 

 Warnell, southwest portion of the Santiago Toscano and W. H. Crain head- 

 rights, and comprises an area of about nine square miles. At the Berry 

 Hill, on the old Hagarty farm, this field forms a broad plateau, comprising 

 some four thousand acres, a large part of which is underlaid by iron ore. 

 The following section shows the general mode of occurrence of the ore:* 



1. Red sandy clay, with seams of hardpan and rounded ore pebbles one-fourth 



to two inches in diameter 2 feet. 



2. Mottled sandy clay, with same pebbles as 1 5 feet. 



3. Intefbcddcd seams of iron ore and hardpan 15 feet. 



4. Mottled red and white sandy clay 10 feet. 



Bed No. 4 runs to the foot of the hill and becomes covered by drift sand 

 in the bottom of a creek, so that only ten feet of it can be seen. The iron 

 ore in the above section is a brittle, stratified brown hematite. On a hill to 

 the north of this exposure was seen a bed of conglomerate ore from one to 

 two feet thick, and at about the same level as the last mentioned bed. Some 

 of the pebbles in the conglomerate bed appear to be fragments of broken up 

 limonite geodes. 



A quarter of a mile to the northeast of the last exposure was seen a series 

 of alternating beds of conglomerate ore, laminated ore, and a variety com- 

 posed of geodes from one to eight inches in diameter, cemented together by 

 a sandy ferruginous matrix. Each of these beds is only a few inches thick, 

 and are separated by sand and mottled clays, the whole series having a 

 thickness of about fifteen feet. The geodes are brown on the outside and
