T'j68] WATERS OP TISHOMINGO. 271 



therefore owing, no doubt, to a certain amount of the Sulphates of 

 Alumina (" Alum ") and of Lime (Gypsum). 



The character of the wells in the Tombigbee Hommock has 

 been referred to (lfo3">>. Deep bored, and artesian wells would 

 no doubt succeed in its northern portion as well, as further S. 

 between Aberdeen and Columbi s. 



5i>8. Waters of the Rot/en Limestone Region. — Generalities 

 concerning these have been given in the Geological Report (H 122, 

 123, 125). Sipe-wells are so rarely practicable, that we may 

 generally consider the alternative as lying between cisterns and 

 deep bored wells, in some of which the water rises above the 

 surface, in others only within available distance. In the latter 

 case, either a pump, or more commonly, a long narrow bucket, of 

 the diameter of the bore, having at the bottom a valve opening 

 upwards, is employed in bringing the water to the surface. 



In consequence of the dip of the Rotten Limestone stratum, these wells are, 

 of course, deepest at the western border of its region of occurrence, and quite 

 shallow on the eastern side ; while wells situated at no great distance north- 

 ward or, in the southern portion, north-westward of one another, are generally 

 of similar depth. In the southern portion, depths increase pretty regularly 

 between 25 and 30 feet per mile, westward or south-westward ; but in Tisho- 

 mingo, there is less regularity, and shallow sipe-wells are not uncommon. At 

 Farmington, there are sipe-wells 20 to 25 feet deep, with freestone water, and 

 others 40 to 50 feet, with limy water, possessing but little rise. — At Corinth, 

 bored wells 70 feet deep, in which the water rises to within 12 to 15 feet of the 

 surface. A deeper bore would doubtless bring it out above the surface, so soon 

 as another vein of water should be struck. — A few miles E. and N. E. of Bone 

 Yard, wells 250 to 270 feet in depth have been bored. At Bone Yard, as might 

 be foreseen, no water was struck in a bore of 200 feet (it could not be expected 

 at less than 825 to 350). — At Kossuth, some sipe wells 18 to 20 feet deep, and 

 a bored well (Mr. Wright's) of 270 feet. 



At Rienzi, wells 60 to 75 feet ; water rises only 15 to 20 feet. There is a 

 very good chance here of a much higher rise within the next 2 to 300 feet. — 

 Due W. of Rienzi, near Mr. Bynum's, S. 7, T. 4, R. 6 E., sipe-wells 20 to 25 

 feet ; a little further N". E., the same, or bored wells 200 to 260 feet. 



At Blackland, wells are comparatively shallow — 120 to 140 feet; the 

 water rises only 15 to 20 feet, and the vein is probably a different one from that 

 supplying the wells heretofore enumerated. 



At Mr. J. W. Yates', S. 11, T. 6, 11. 6 E., bored well 35 feet ; little rise.— 

 At Carollville, about the same. On S. 36, T. 6, R. 5 E , at Mr. Humphrey's, 

 200 feet.— At Mr. McManus', S. 35, 210 feet; Dr. Agnew's, S. 27, 271 feet; 

 half a mile E. of Dr. A's, 210 feet. The depth increases westward and 

 northward from Dr. Agnew's— there being wells 300 and 330 feet deep. In 

 all of these, the water rises to within 40 to 70 feet of the surface, according to 

 elevation ; that of the five last n;im;d wells is pretty limy, that of McManus' 

 excessively and unhealthily so ; most of them (e. g. Dr. Agnew's) are slightly 

 sulphureous and chalybeate. 



The examples may suffice to show the condition of things in 

 Tishomingo. Very nearly the same exists at corresponding points 

 of the Rotten Limestone belt in Pontotoc and Itawamba counties, 

 the deepest bores rarely exceeding '■'{)() feet, water rising within 

 40 to tU feet of the surface. Here also, deeper bores might bring 

 artesian water, derived from the high Pine lauds further E. (1532) ; 

 thus far, cisterns are extensively used.
