oysters and other fossils of the Rotten Limestone ; the material in the lower 

 portion being rather sandy, hut passing over by degrees into the Rotten Lime- 

 stone above — none of which is seen E. of Carrollville. 



113. The formations in N. W. Itawamba, I have but partially examined, and 

 am not therefore certain of the lino given there. The Rotten Limestone appears 

 some distance E. of Guntown Station on the M. & 0. R. R., and seems to 

 touch 20 Mile Creek ; at Guntown, nothing but the limestone is seen in either 

 cuts or wells. E. of Richmond, on the Fulton road, on the waters of the Rogue 

 Eucaby.and eastward of the same, strongly micaceous sands appear in the wells, 

 which at first have limy water, but the less so as we approach the Tombigbee. 



Near Borland P. 0. (Squire Connel's, S. 18, T. 11, R. 8 E.), bluish micaceous 

 sand, sometimes cemented into a soft sandstone, is found in wells and beds of 

 creeks. A few miles westward, however, the heavy "beeswax hommock" soils 

 of the Rotten Limestone appear on the higher ridges, and shortly after, the latter 

 itself is struck in wells and outcrops. At Coulter's Ferry (l[106, Sec. 4), the 

 Tombigbee Sands are sparingly represented by a few feet of micaceous material 

 underlying the Rotten Limestone ; and between this and Aberdeen, micaceous 

 sand is struck in wells on the W, bank of the river, after passing through the 

 Rotten Limestone. 



Near Aberdeen, we find the stratum finely developed in a bluff on the Tom- 

 bigbee river, on Dr. Tindall's land :

At the Aberdeen Ferry, the micaceous sand crops out on both banks, up to 8
