CHEROKEE COUNTY. 



289 



A sample of the lignite from this locality, submitted to analysis by Mr. L. 

 E. Magnenat, afforded the following composition: Water, 9.12; volatile 

 matter, 30.32; fixed carbon, 34.22; ash, 22.98; sulphur, 3.36. 



The lignite outcrops in several other localities in this county which were 

 not visited by the writer, but the character of the lignite, as it belongs to the 

 same deposition, is probably similar. 



The following specimens of lignite, submitted to analysis for this report, 

 were collected by Dr. R. A. F. Penrose, Jr., more than a year ago, which will 

 account for the difference in percentage of moisture, etc. :

 No. 1109. Brown lignite, six miles south of Alto. 

 No. 1110. Lignite, near Jacksonville. 

 No. 1111. Lignite, McBee school. 



On the west bank of a little branch tributary to the one above mentioned, 

 J. W. McCord's place, John H. Furgison headright, was seen ten feet of mi- 

 caceous lignitic sand of creamy color above and brownish at base near the 

 water. Overlying this deposit is the surface soil drift, about two feet thick. 

 The position of the micaceous sand is above the lignitic clay shale. 



MINERAL WATER. 



Chalybeate Springs. — Wherever the disintegrated iron ore has drifted 

 into contact with organic matter the access of water by infiltration gives 

 origin to chalybeate springs. The carbonic acid gas derived from the slow 

 oxidation of the organic matter is held in suspension by the water, which 

 coming in contact with the iron ore dissolves a portion of the iron. On 

 reaching the open air the carbonic acid gas is gradually given up and the 

 iron, no longer soluble in the water alone, is deposited as a rusty sediment. 

 When this sediment is deposited on a bed of small iron pebbles and iron 

 gravel, which usually line the margins of streams in this region, the pebbles 

 and gravel are cemented into a soft iron conglomerate. This was seen in 

 process of formation in a little stream in the northern limits of the town of 

 Rusk and elsewhere 



Sulphur Springs. — Several springs of sulphur water have been reported 

 in the eastern portion of the county on the tributaries of the Angelina River.
