168 THE IRON ORE DISTRICT OF EAST TEXAS. 



lern and David Furguson headlights and along the east side of the William 

 Robinson headright to the northeast corner of this survey. The line then 

 turns west to near the northeast corner of the Henry Hathaway headright, 

 and thence southerly along Hawkins' Creek, through the W. H. Castleberry 

 headright, to the south side of the same survey. It then turns east and north- 

 east to the northwest corner of the Isaac Skillern headright, and from that 

 point in an irregular line to near the Sabine, on the southwest corner of the 

 Alexander furguson headright, and then eastward through the Furguson 

 and Marshall Mann headrights to the crossing of the public road and Inter- 

 national and Great Northern Railway. This field comprises an area of about 

 fourteen square miles. 



The ore over the greater portion of this field is thin and scattering, and 

 consists chiefly of conglomerate and nodular ore, with a great proportion of 

 ferruginous sandstones. The only heavy deposits are those along Hawkins' 

 Creek near the western boundary of the field, and these are chiefly of a sili- 

 ceous variety of conglomerate ore. 



Throughout this ore field all the various classes of ore found in East Texas 

 are represented. On the east side of the Wm. Robinson headright, near the 

 old Allison place, the ore is represented by a gray ferruginous sandstone. 

 This sandstone is found in a fragmentary condition, scattered over the sur- 

 face of the ground in pieces ranging from two or three inches to sixteen or 

 eighteen inches or more in length, and although generally in flat pieces, many 

 of the larger fragments present the appearance of having been formed around 

 some central nucleus, which has since been removed, giving the sandstones 

 the figure of a broken earthenware pot. Across the Isaac Skillern headright 

 and on the west side of Grace's Creek the ore exposed in many places is in 

 the form of a conglomerate, carrying not more than 32.61 per cent of metallic 

 iron, and also as a highly ferruginated sandstone, which will probably carry 

 in the neighborhood of twenty-five per cent of iron. 



Crossing to the eastern side of the W. H. Castleberry headright, consider- 

 able deposits of a poor quality of conglomerate ore are found lying along 

 both banks of Hawkins' Creek. On the west side of the Wm. Robinson 

 headright, and through the central portion of the Isaac Skillern headright, 

 small scattering deposits of nodular concretionary and an ochreous concre- 

 tionary ore are to be found covering the surface of the ground, but in very 

 few places were these nodules found to extend to more than a few inches in 

 depth. An analysis of a sample of the ochreous variety of these ores found 

 on the Gilmer and Longview road, near the junction of this road with the 

 road to Gladewater, gives the following:
