HARRISON COUNTY. 131 



headlight the surface ore shows a thickness of five feet. Near the centre 

 of the headright, at Mr. J. B. Hall's house, a well forty-three feet deep 

 passed through a bed of laminated ore six feet thick at a depth of twenty - 

 seven feet, and after passing through len feet of yellow sand underlying the 

 ore bed the well stopped at a lower bed of the same grade of ore. The 

 thickness of this lower bed is not known, as it was not cut into more than a 

 few inches. 



On the S. Wagley headright, at Hynson's Mineral Springs, and a hill 

 about three-quarters of a mile west, the three classes of <>re occur, having a 

 combined thickness of probably twenty feet. These ores lie in different posi- 

 tions on the hil., and their thickness is hard to arrive at with any degree of 

 satisfaction. 



On the Ephraim Tally headright Barnes' Hill shows a deposit of crumbly 

 ore about six feet thick. Through the Francisco Calvillo, W. B. Rhea, and 

 Samuel Jordan headrights the ore deposits do not exceed two feet. On the 

 Henry Teal headright the ore deposit is not over two feet in thickness, of 

 which one foot is a laminated ore of the massive variety. In the northeast- 

 ern portion of the ore region, on the Thomas Gray and Lewis Watkins head- 

 rights, a ridge of laminated ore ten feet in thickness occurs. The upper 

 division is broken, fragmentary, and associated with red sand. The lower, as 

 exposed in the Marshall and Jefferson public road, lies in a solid condition 

 two feet in thickness. 



Following the methods employed in describing the iron ores of the other 

 counties in East Texas, the ores of Harrison County may be divided into 

 three classes: 1, Laminated Ore; 2, Geode or Nodular Concretionary Ore; 

 and, 3, Conglomerate Ore. Of these the laminated and conglomerate ores 

 are the most extensive in their development. The geode or nodular concre- 

 tionary ores, although found more or less scattered throughout the yellow 

 and brownish yellow sands of the higher ridge through the centre of the 

 county, are more intimately connected with and best developed among the 

 dark brown or orange-red sands belonging to the second or middle division, 

 lying at a lower level around the base of the ridge. Although laminated 

 and conglomerate ores occur associated with these sands, the occurrences are 

 rare and the ores not of a sufficient extent, except in very few places, to be 

 of any practical value. 



In the detailed descriptions of these ores the localities given are those in 



which the ores are most prominently developed. The smaller deposits found 



outlying among the gray sands in the eastern portion of the county are not 



considered of sufficient value to be enumerated.
