246 THE IRON ORE DISTRICT OF EAST TEXAS. 



the sandy clay overlying the mottled red and gray clay, as seen in the west 

 bank of the railway cut, as will appear from the following section: 



1. Light sandy soil 6 inches. 



2. Yellow sand 2 feet. 



3. Yellow sandy clay, to bottom of cut 2 feet. 



No. 3 contained a belt or pocket of small nodules one-half inch to one and 

 one-half inches in diameter, having dark nuclei of bluish black color, which 

 afterward proved to be mainly black oxide of manganese, associated with 

 ferric oxide and alumina. 



FRESH WATER SILICEOUS LIMESTONE. 



About seven miles south of Timpson, near the crossing of Bear Bayou, on 

 both sides were seen ledges of this limestone, similar to those seen in Panola 

 County, but somewhat denser and of a deeper blue color, indicating more 

 lime and less silica. The ledge on the north side was of considerable extent. 



At the residence of Mr. C. Silas Barnes, eight miles south of Timpson, in 

 the J. A. Rodrigues headright, are found large ovoid nodules of this lime- 

 stone several feet long by four to five feet wide, with radial cracks which 

 have been filled with crystal calcite. 



Near this locality it was also seen as an outcrop on the side of a hill, and 

 again in a gully between the hills on the A. C. Thornbery headright. 



About five miles south of Patroon, on the Matlock place, in Wm. Nethery 

 headright, both yellow and blue siliceous limestone bowlders were seen near 

 the top of a hill, or at a higher elevation than it had been observed before. 



An outcrop was also seen on a hillside bordering a fork of the Attoyac 

 Creek, on the Bryant Humphrey headright, in the western part of the county. 



LIGNITE. 



About seven miles south of Timpson, in the northeastern portion of the W. 

 J. Crump headright, at the falls of a small stream, a tributary of the Attoyac 

 Creek, in a gully about eleven feet deep, a bed of lignite apparently four or 

 five feet thick was seen. It formed the bed of the gully and was similar to 

 the lignite bed of Panola County 



No other exposures of the lignite bed were observed in this county, but it 

 is probable that it is of considerable extent. 



TIMBER GROWTH. 



The total area is 513,280 acres, of which 47,000 represents the total field, 

 fruit, and garden area in cultivation, leaving 466,280. If from this be de- 

 deducted 46,628 acres for town sites, barrens, and streams, and from the re-
