 similar distance W. of the Cretaceous formation (see map), as farS.asS 

 Calhoun Beyond, until we approach the marine Tertiary (IT 188, to 239) the 

 rlinnces are not so strong, though by no means hopeless. It seems possible that 

 ?arSanweUs might be obtained, not only on the whole of the territory of the 

 Northern Lignitic (see map), but even in the Mississippi Bottom itself. 



As to the practical difficulties likely to be encountered in these bores they are 

 not greater than those of the Jackson well (^321) ; boring itself wdl be easy, 

 but tubing may be required to considerable depths. 



6b9. Mineral Waters.-As to the mineral waters of this region, 

 generalities regarding them have already been given (175 ; 614). 

 I subjoin, however, some detailed analyses made. They are chiefly

 Iron with Bicarbonate* of Lime, Magnesia, Manganese and often Soda , also 

 some Common Salt, ami sometimes Chloride of Magnesium ^ r<f*hum; 

 but few, or no Sulphates. Some free Carbonic And ; sometimes a little Sul-

 (T75). The spring found, some time ago, on the M C. R. It., 2 .miles a. ot 

 Oxford was of this character ; so are some, at least, of the waters of the Lafayette 

 3 which I have not as yet visited ; and, in Marshall county, those on 

 theland of Isham R. Frost, Esq., of Mt. Pleasant-situated in the bottom of 

 Cold Water River ; they contain about one-seven thousandth, by weignt, oi 



^iTTldine chalybeates containing chiefly Sulphates, also some Chlorides 

 and generally some bicarbonate of Iron, and, very commonly, some Sulphuretted 

 Hvdro-en flow from the lignitic strata themselves, or are found in wells in the

 Sulphates of Soda, Lime, Magnesia, largely ; of Potash, little.
