178 THE IRON ORE DISTRICT OF EAST TEXAS 



easterly and westerly direction. The hill to the west has an elevation of one 

 hundred and fifty feet (bar.) above the level of the rails of the Missouri, 

 Kansas and Texas Railway at the Daingerfield station.* A section of the 

 region in this neighborhood shows: 



1. Ferruginous gravel and iron ore found in well on top of hill 80 feet. 



2. G-reensand in well, but not bored through. (This greensand appears in the form 



of a broken ledge of soft yellowish green sandstone along the face of the hill 

 at an elevation which would indicate its having a thickness of at least twenty 

 feet) 6 feet. 



3. Mottled yellow, brown, and white sand 15 feet. 



4. Thinly laminated bluish iron-stained sands or clayey sands 4 feet. 



5. Light bluish, white, or yellowish white clayey sand 4 feet. 



6. Micaceous black sandy clay, with thin streaks of lignitic matter 8 feet. 



7. Dark blue sandy clay, enclosing bowlders of red sandstone, containing imprints 



of leaves, visible 2 feet. 



8. White sand or sandy clay 50 feet. 



Total 119 feet. 



Numbers 1 and 2 of this section are from a well on the top of the west 

 hill; 3, 4, 5, 6, and 7 from a brook north of the town; and 8 from a washout 

 in Dr. Brad field's farm at the base of the east hill. The ore of this region is 

 chiefly of the concretionary class in the form of a dark brown or black 

 variety, and considerable quantities of the black nodules have a radiated or 

 fibrous structure. The surface of this district is covered with a mass of fer- 

 ruginous sand, gravel, and fragments of ore of varying sizes. Although 

 the greater portion of these ore fragments do not exceed two to four inches 

 in diameter, many of them range from two to four feet in their greatest length. 

 These large bowlders are found mostly high up the sides of or on the sum- 

 mits of the hills. The line of the ore deposit is difficult to make out, and 

 probably does not exceed two or three feet in thickness. The deposit itself 

 forms a covering of the west hill, but on the hill next the town it is covered 

 by a heavy deposit of sand. 



The ferruginous sands flanking and running high up the hillsides are 

 heavily charged with ore nodules and fragments of the same character as 

 that of the bowlders on the tops of the hills. In thickness this sand varies 

 from two to fourteen feet. The lower portion of the deposit is generally free 

 from ore or gravel. 



Masses of 'a soft greenish yellow colored sandstone or altered greensand 

 occur throughout the whole ore and gravel along the lower portion of the 

 hillsides, and a belt of this material ten or fifteen feet wide in the form of 

 broken bowlders occurs about fifty feet from the tops of the hills. This belt 

 forms a small bench, and the broken sandstone found along it appears to in- 



* The elevation of the rails at this station is 398 feet above tide.
