 This analysis (which was made solely for the purpose of ascertain- 

 ing the ingredients foreign to the clay proper) proves the singular 

 fact that this clay, though occurring in a formation characterized 

 by the large amount of iron it commonly bears, contains a 

 remarkably small amount of that substance ; which, together with 

 the minute proportions of linie and magnesia, explains its 

 intiisibility. 



On S. 7, adjoining Clingscale's, at Mr. Hutchins' place, there is 

 an outcrop of cream -colored clay, which also becomes whiter in 

 baking, and is very refractory. 



64. At Mr. Lovress' place. S. 17, T. 4, R. 11 E., strata of white 

 ■conglomerate, similar to that at Aleck Peden'f, were struck in a 

 well at 28 feet ; minor layers of beautiful white clay were encoun- 

 tered above this. An outcrop of pure white clay occurs on 

 Peniwinkle Creek, on S. 8, just X. of Mr. Lovress'; the soil of the 

 bottom shows plainly the admixture of this material by its whitish 

 tint. 



On S. 18, at New Warren ton, the white clay has also been found. 

 Thence in a N. W. direction, the white materials appear in cut? 

 on the Memphis and Charleston Railroad, near Iuka. and at Mr. 

 Null's, S. 22, T. 3, R. 10 E.; overlaid, in all cases, by pebbles or 

 pebble conglomerate. In the localities mentioned, however, the 

 quality is inferior so far as visible (a few feet only), being rather a 

 fine clayey sand than a clay, and traversed occasionally by red 

 streaks. It is possible that at some depth, the quality might 

 improve, as in other cases. In the railroad cuts, the white material 

 was said to contain at times large lumps of dark red clay, the 

 latter being even found independently, in the valley of Clear Creek, 

 underlying the pebbles. 



65. In none of the localities heretofore mentioned, the geological position of 

 the white strata, and their connection with the Oringe Sand, could be decisively, 

 established. At Mr. Aker's grist-mill, on S. 24, T. 3, K. 10 E., the following
