PANOLA COUNTY. 237 



erate, but no continuous stratum. A few pseudomorphs after iron pyrites, and 

 detached fragments of silicified wood, partly ferruginated, were also seen. 



In the bed of Six Mile Creek, or Cypress Bayou, some micaceous sandy 

 shale was seen in contact with the lignitic siliceous limestone. The exposure 

 as seen was about three feet thick on the Thos. F. Hull tract. 



Detached and water worn specimens, six to eight feet long, five to six feet 

 wide, and about one foot thick, were afterward seen exposed on either side 

 of the Texas, Sabine Valley and Northwestern Railway, two miles north of 

 Beckville. This fresh water limestone has already been referred to its strati- 

 graphic position.. The' number of fragments and bowlders seen in various 

 localities point to the fact that it was once a stratified deposit of considerable 

 extent, but afterwards eroded, displaced, and waterworn, so that it is now 

 generally found partially preserved in detached masses. 



On the summit of a ridge about one and seven-eighths miles north of 

 Beckville, on the railway, was seen geode limonite associated with a very 

 considerable quantity of iron gravel. These geodes here have a thickness 

 from eighteen inches to two feet, and vary in composition and value from 

 the ochreous clay iron stone centre, to the more compact concentric shells of 

 limonite, which by fracture and weathering became the origin of the iron 

 gravel in this locality. 



In the southwest corner of the Wesley Gooden headright, near Riley W. 

 Kinard's residence, in the road to Beckville, about half a mile south of the 

 ford of a small branch, a tributary of Martin's Creek, was seen the following 

 section : 



1. Iron sandstone 18 inches. 



2. YeLow vesicular ochreous sandy iron ore 3 feet. 



3. Heavier sandy iron ore 2 feet. 



4. A thin stratum of septum iron ore, with red and yellow ochreous inclusions, 2 inches. 



This arrangement seemed to be a local variation in the deposition of the 

 iron series. 



A tendency to the formation of septum ore was afterwards seen in several 

 places. The ore on the summit of Mineral Spring Ridge is somewhat of 

 this character. Portions of it were sometimes seen elsewhere as nuclei of 

 geodes. 



Near this locality, in the southeast corner of the Daniel Martin headright, 

 Selman tract, on the summit of" a ridge, was noticed the following section: 



1. Conglomerate iron ore, irou sand cement 2 feet 6 inches. 



2. Iron sandstone, often adhering to No. 1 . . .♦. 2 feet 6 inches. 



3. Geode bed, mingled with iron gravel, covering the northwest side of the 



hill Displaced. 



4. Sandy ferruginated clay, with iron pebbles from disintegrated conglom- 



erate To base of hill.
