11287, 288, 269] marls of smith — jasper — clarke. 173 



287. With the character of the marls in the Polkville region, I 

 am not acquainted ; but from what I have heard, they arc similar 

 in general to those near Brandon. 



N. of Raleigh. Smith county, at Mr. Austin's mill (1227), we 

 find mails corresponding in every respect to those at and above 

 Byram, which sec ("280) ; though on the whole, perhaps, they are 

 a little more sandy ; in some places they contain a good many 

 greensand grains. The marl into which the pit for the water 

 wheel is dug, is rather inferior to that which is found a few hundred 

 yards lower down, outcropping on Shongalo Creek. Outcrops of 

 a similar character are said to exist on the Okahay, and on Leaf 

 River ; the same marl could no doubt be found under the ledges 

 of limestone which come to the surface on the lower slopes of the 

 ridges tailing off towards Shongalo and Bowlands Creek, and may 

 be looked for on Hatehushe and West Tallahala Creeks, E. of 

 Raleigh, and S. of the "Hog-wallow prairie"' region, in which only 

 the clay marls of the Jackson Group (see above, 11202 and if.; 282) 

 are to be looked for. 



y88. The latter occur, very characteristically, near Garlandsville, 

 and generally on the black prairies, or "shell prairie," on both 

 sides of the Paulding ridge. On the bald prairies S. of Suanlovey 

 Creek, near Garlandsville, we find all the several varieties of the 

 white or yellowish clay marls occurring near Jackson and in the 

 McNutt Hills -heavy calcareous clays with but a small percentage 

 of lime, and some gypsum ; and soft, easily crushed marls, with 

 ferruginous casts of shells, resembling those of Moody's Branch and 

 Langley's field (see above, II 28'-', 2So), and probably of a similar 

 composition also. The great sandiness of the ridge soils of this 

 region would render these clay marls particularly suitable to their 

 improvement. 



Of the marls of S. Jasper, I know nothing personally ; they are said to resem- 

 ble partly those of the Brandon neighborhood, partly the sandy varieties of the 

 Vicksburg marl — as do those of the same formation in Wayne county. The 

 country being hilly, they appear only in the deep ravines, and beds of water 

 courses. 



289. In Clarke and Wayne counties, we have a great variety of 

 mineral fertilizers. 



Beginning at the north, we find in the banks of the Chickasaw- 

 hay River at Enterprise, strata of shell-bearing, calcareous sand, 

 containing a huge amount of greensand grains. 



The stratum (Nos. 2 and 3 of Sec. 24, l)T!)O l ) as exhibited in the town of 

 Enterprise, is so rich in greensand grains, that notwithstanding its sandiness, 

 this material would be an eligible manure wherever it is conveniently accessible 

 and does not require to be hauled to any great distance. It is very likely, how- 

 ever, that the river bluff below the town, where a large exposure of stratum No. 

 3 may be looked for, will be found to contain materials of gi eater purity, which, 

 for their action as true manures and not mere stimulants, would be ol especial 

 value. Portions of this bed greatly resemble that near Shongalo (if 274 and ff.) 

 and it is quite likely that the two deposits are connected, in which case, similar 

 materials might be looked for in N. Newton, Leake, and E. Attala. Sim-
