270 THE IRON ORE DISTRICT OF EAST TEXAS. 



A bed of red clay, giving an exposure about one mile in length, was ob- 

 served in the same road, five to six miles west of the town of Nacogdoches. 



About eight and a quarter miles west of the town, in the same road, was 

 seen a bed of stratified clay several feet thick, overlaid by iron sandstone 

 and remnants of iron conglomerate. Under the clay is a bed of hardpan 

 grayish sandy clay, which rests upon mottled red and yellow sandy clay. 



About eight miles southwest of Nacogdoches, in the old San Antonio road, 

 there is a considerable bed of red clay, from which projects a stratum of cal- 

 careous ferruginated shell rock. This clay bed is an extension of that seen 

 at Simpson's Hill. 



SILICEOUS LIMESTONE. 



On a tract of land adjoining W. J. Peterson's on the north, near Pitze 

 Station, there is an exposure of this rock, close to which was observed some 

 of the upper shaly strata of the lignitic series. Other exposures of this lime- 

 stone were seen in the railway cut about two and a half miles northeast of 

 Garrison. A few scattered nodules of the material were observed on the 

 hillsides near Cherino. 



LIGNITE. 



Except a streak of asphaltic clay near Fitze, no exposures of the lignite 

 bed were seen in traveling through this county, but it probably exists in the 

 eastern portion, forming an irregularly serrated line southward. In passing 

 from the office of the Lubricating Oil Company to Cherino, on the north side 

 of the road between a saw mill and the latter, is a well recently dug on a 

 ridge, which, judging from the dump, had penetrated the lignitic shales. 



MINERAL WATER. 



Within the limits of the town of Garrison is a spring which is frequented 

 by persons who believe they derive benefit from the use of the water. 



The property has been recently improved by excavating about seven and 

 one-half feet and building a circular wall about three feet in diameter, capped 

 with a heading of hydraulic cement. Over this is an octagonal pavilion of 

 wood, about thirty feet in diameter. A company has been formed with a 

 project for building a $5000 hotel, with half the capital subscribed in the town. 

 The water is from the main water bearing sand, which overlies the lignite. 



The water belongs to the chalybeate class, and judging from its taste ap- 

 parently contains iron, magnesia, alumina, carbonic acid, and perhaps a little 

 free sulphuric acid derived from the decomposition of iron disulphide (pyrites). 



Sulphur Water. — There is fine sulphur water fourteen and one-half miles 

 southeast of the town of Nacogdoches. The property has been improved by
