(Sec. 3.) 

 SECTION AT WARREN'S MILL, ITAWAMBA COUNTY. 



CHARACTER OF STRATA. 



40 Wooded hillside — Orange Sand on top. ' 



. Yellowish sand resembling that commonly overlying the 

 laminated clays ; possibly in secondary place. 



. Sand similar to the above, filled with compressed lignitized 

 trunks, often covered with pyrites. 



2. 3 Lignite & nodules of brown hematite, in ferruginous matrix 



5 Dark colored, greenish, sandy clay, with an irregular, 

 twisted or nodular stratification. 



^2~2 Yellowish-green sands, micaceous. 



Thin layers of sandy, green, bluish, red or gray clay, 



interstratified with greenish sand, 

 with pyrites imbedded in the mass. 



Lignitized trunks 



The lignite found here is very much decomposed, so as to afford little hope of 

 identifying the species of the trees. Not uncommonly there are found among 

 the lignite rounded masses of fossil resin of a grayish yellow tint, with bands 

 more or less translucent, resembling agate. It is very brittle, and when rubbed 

 emits a faint aromatic odor. The latter, as well as the aspect of the material, 

 strongly reminds one of hardened sweet gum or Styrax liquida. A portion of 

 a disc-shaped mass of this substance, which originally was about four inches in 

 diameter by 1}£ m thickness, was presented by Mr. J. C. Reinhart. 



The characteristic fat laminated clay does not occur in this section ; it appears, 

 however, in the bed of the creek, lower down, and in bluffs on Big Brown's 

 Creek. E. of Marietta. Thence southward, however, we find exhibited in 

 many localities on the Tombigbee River, down nearly to the Monroe line, strata 

 of the same character as those just described, viz : consisting of alternating 

 layers of sand and clay of variable thickness, from 0.1 of an inch to 2 inches 

 and more. Such are the outcrops on the Tombigbee, near Fulton, from which 

 numerous mineral springs flow, and also those at Van Buren ; at the latter 

 place, there intervenes between the upper sandy portion and the more clayey 

 beds b3low a thin ledge (1 to 2 inches) of fine grained, brownish aluminous 

 sandstone.
