74 THE IRON ORE DISTRICT OF EAST TEXAS. 



The elevation of the mouth of this well is about 440* feet above sea level. 

 Other sections from pits and wells in the neighborhood show the same suc- 

 cession of strata, but with varying thicknesses. 



GENERAL SECTION. 



A completed section of the strata of Cass County appears to be, from all the 



information obtainable, as follows: 



Yellow, brown, and red or orange sands, unstratified and irregularly laid down, 

 containing nodular concretionary ore deposits and beds of laminated ore and fer- 

 ruginous sandstones 200 feet. 



Iron ore, mostly laminated, and accompanying sandstones . 10 feet. 



Stratified and unstratified red and white and mottled sands, black, yellow, and red 



clays, and sandy clays, and occasional deposits of lignites 183 feet. 



393 feet. 



IRON ORES. 



The ore beds or deposits of Cass County are generally in the form of ag- 

 gregations of bowlders and nodules. The conglomerate ores are usually in 

 large irregularly shaped or rough rectangular blocks. The geode, or nodular, 

 concretionary ores, have various forms, usually rounded, oval, or lenticular. 

 There are, with the exception of some small deposits of laminated ore, no con- 

 tinuously bedded ores within the county. The geode, or nodular, ores fre- 

 quently lie upon the same plane, and are so closely packed together as to give 

 them the appearance of a continuous bed. 



Thickness. — In thickness these deposits vary from a few inches to a maxi- 

 mum of ten feet. This maximum, however, occurs in very few places, and 

 even then it is generally Droken by the intermixture of thin beds of a white 

 or yellowish colored sand. 



In the western division the heaviest deposits found have thicknesses of 

 from six to ten feet. Near Hughes' Springs a well on the Burleson headright 

 shows an iron deposit twelve feet thick. In this well the ore is mixed with a 

 yellow colored ferruginous sand. On the E. West headright a well passed 

 through four or five feet of ore. To the north of Hughes' Springs a well on 

 the Burris headright shows ten feet of ore mixed with yellow ferruginous 

 sand. Several old pits dug in the neighborhood of Hughes' Springs show the 

 ferruginous ores to be four feet thick. In the railway cutting, three miles 

 west of Hughes Springs Station, the ore has a thickness of ten feet. Here it 

 is also much mixed with brown sand. 



Near Avinger, on the Andrew J. Fowler headright, a siliceous ore four 

 feet thick underlies a yellow sand having a thickness of two feet. 



*The altitude of Hughes' Springs Station, on the Missouri, Kansas and Texas Railway, is 

 379 feet above the level of the mean tide of the Gulf of Mexico, and these levels are from baro- 

 metric readings, having 379 feet as their base.
