only ones much resorted to. The former is described in the Sur- 

 vey's report on mineral waters. ^ 



Mineral Springs, Clark county, are two miles northeast of 

 Antoine post-office, a quarter of a mile south of the military road, 

 immediately on the Amity- Okolona road. Seven springs issue 

 near each other and one larger spring a short distance away. These 

 springs are well tiled and the large one has a cover. The water 

 issues from a dark-colored, sandy deposit, with streaks of black 

 shale or clay, all of which are probably of Cretaceous age. These 

 beds dip to the south at an angle of 45°. The place is used as a 

 local summer resort and camping place. An open Methodist 

 Chapel, a dozen or more summer cottages and frames for a number 

 of tents have been built at this locality. 



The others have all been largely resorted to. For the past few 

 years it has been claimed that there have been as many as five hun- 

 dred people spending more or less of the summer at Baker's Springs. 

 The principal constituents of these springs is given by Owen ^ as 

 follows : 



Analysis of Baker's Stdphur Spring Water. 



" Carbonate of alkali, which is probably in the state of carbon- 

 ate of soda. 



'' Chloride of sodium. 



*' A small quantity of free sulphuretted hydrogen. 



*' Traces of sulphate of soda and magnesia. 



" When boiled down it exhibits strong alkaline properties. Its 

 medical properties are a mild laxative ; a diuretic, antiscorbutic, 

 slightly alterative and strongly antacid. This spring rises from the 

 slate at the base of a ridge of quartzose sandstone. 



"There are also several other mineral springs in this neighbor- 

 hood, in Polk county. One at Samuel Gray's on section 20, Town- 

 ship 5 north. Range 29 west, its temperature 58°, the air being 52° 

 (also known as Shurd's Sulphur Spring, G.H.A.). The main char- 

 acteristic constituents of this water are: 



'* Carbonate of soda. 



" Chloride of sodium.
