158 THE IRON ORE DISTRICT OF EAST TEXAS. 



Panther, and Clear creeks. On the north side of the Little Cypress the creeks 

 tributary to that stream are Bear, Lick, and Eagle creeks. 



For mining purposes these creeks would require to be dammed and the 

 water stored; otherwise, with the exception of Sabine River and Little Cypress 

 with its associated lake system, the water supply would be insufficient for the 

 necessary work in connection with the manufacture of the iron ores of the 

 county. 



Good wells and many springs are found throughout the county. Wells 

 descending as low as the micaceous black clays and greensands, as well as 

 many entering the deep lying blue clays, have their waters impregnated with 

 sulphate of iron. The wells belonging to the Marshall City Water Works are 

 bored to a depth of sixty feet, and pass through a deposit three feet thick of 

 dark blue clay. The water from these wells is charged with a small quan- 

 tity of sulphureted hydrogen. The water when allowed to stand in the 

 pipes smells strongly of this gas but has no unpleasant taste. 



The only navigable waters in Harrison County are those of Caddo Lake 

 and its extension to Jefferson, and the Sabine River. The latter is navigable 

 for small river boats as far as Easton Ferry, in Gregg County, for probably 

 four months in the year. No navigation has been carried on for some eight 

 or ten years. 



MINERAL SPRINGS. 



There are numerous springs of chalybeate water scattered throughout the 

 county, but only three of these are utilized either as health or pleasure re- 

 sorts to any extent. These are Hynson's Springs, Roseborough Springs, and 

 Montvale Springs. 



Hynson's Springs have already been described by Dr. Penrose. (First An 

 nual Report Geological Survey of Texas, p. 99.) 



Roseborough Springs are a series of springs lying on the side and at the 

 base of a small hill on the H. C. Lewis headright, about nine miles south of 

 Marshall, and from eighty to one hundred feet (bar.) beneath the elevation of 

 the town. The mam spring has a flow of about ten gallons of water per 

 minute. The water is a pale amber color, and when allowed to stand for some 

 time throws down a dark colored sediment. 



These springs are chalybeate, and contain chiefly iron and alumina with 

 sulphates of calcium and magnesia. These springs have been recommended 

 for skin diseases and are largely patronized. 



The following is an analysis of the water from No. 1 spring: • 



Chloride of sodium 1 1 . 452 



Sulphate of lime 36 . 617 



Sulphate of magnesia 23 . 123 



Sulphate of iron 16.497
