260 THE IRON ORE DISTRICT OF EAST TEXAS. 



The character of timber trees is similar to that of Nacogdoches County, 

 except the noted absence of long leaf yellow pine, Pinus australis. 



IRON ORES. 



At Mount Enterprise, on the northeastern and northwestern exposures, rep- 

 resentatives of iron pebble conglomerate, iron sandstone, wavy laminated and 

 buff crumbly iron ores were seen covering an area of about two hundred 

 acres. 



About two miles east from Henderson, on the Pine Hill road, were seen 

 ^some large geodes of iron ore, not in continuous bed, but extensive. Two 

 and one-fourth miles from Henderson, on the same road, is a remnant of. a 

 bed of iron pebble conglomerate on the summit of a ridge. Four miles east 

 of the town, on the same road, is a ledge of sandy ferruginated geodes. Five 

 miles east on the same road is another remnantal bed of iron pebble conglom- 

 erate on the summit of a ridge. 



About three and one-fourth miles northeast of Henderson, on the Millville 

 road, large bowlders of iron pebble conglomerate were seen. Seven miles 

 from Henderson, on same road, fragments of iron ore, including buff crumbly 

 ore, were noted. 



In a field at Howard Williams' place were collected fragments of a stratum 

 of fossiliferous iron sandstone containing casts of shells, Cardita planicosta, etc. 



About seventeen miles south of Henderson, at Gould Postoffice, is the 

 northeastern exposure of Iron Mountain, formerly Elkins Mountain. On this 

 ridge there is an extensive remnant of the iron series. The iron pebble con- 

 glomerate has been disintegrated and eroded, but a few tumbled bowlders, as 

 seen in the vicinity of the fault at Sulphur Spring, escaped disintegration by 

 being covered with local drift until uncovered by gully washing, and now 

 attest its former presence. 



The iron sandstone, only a thin stratum of which now remains, was partly 

 eroded, but what is left has served to protect a portion of the wavy lami- 

 nated and underlying buff crumbly iron ore, which here rests upon an ex- 

 tensive local drift deposit of altered greensand marl of the Eocene epoch. 

 The upper portion of this marl or orange loam is fossiliferous, containing 

 casts of Eocene shells, Cardita planicosta, etc. 



In front of L. D. Stevens' house, at Sulphur Spring, faulted and tilted 

 strata of iron ore were observed. Some portions of the limonite are compact 

 and glossy black. The wavy laminated and buff crumbly varieties are also rep- 

 resented. ' The orange loam is here rich in fossiliferous casts of Eocene shells. 



One-half mile east of the Sulphur Spring church and school house is a rem- 

 nant of wavy laminated and buff crumbly iron ore, including fragments of 

 iron sandstone.
