[T171, 172 



possesses fine specimens of leaves occurring in a red, micaceous, schistose sand- 

 stone, near Gov. Matthews' place, in N. E. Marshall county. Of the 

 precise position of the rock in these localities, I am not informed. All of 

 them are probably metamorphoses of different materials of the Lignitic forma- 

 tion, by means of ferruginous solutions derived from the Orange Sand. 



171. The following section, from a bluff in T. 6, R. 1 E., on the Corners- 

 ville and Hickory Klat road, as well as that mentioned as occurring near the 

 latter place on Ccklimita Creek, will give a fair idea of the character of the 

 outcrops observed in S. W. Tippah and S. E. Marshall.

SECTION OF LIGNITE STRATA, FROM AN OUTCROP IN T. 6, R. 1 R. 

 TIPPAH COUNTY. 



This section also represents faithfully numerous oufcrops in S. Lafayette, and 

 N. Calhoun counties — some sections, however, exhibit nothing but sharp, 

 yellow sand, with faint impressions of leaves. The region in which the above 

 section occurs, is remarkable for the number and large size of the ferruginous 

 nodules occurring on the surface of the formation (1f42); silicfied trunks, also 

 being very common in the same position, and remarkable for the per.'ect preser- 

 vation of their vegetable structure. 



172. At Reeky Ford, Pontotoc county, the S. bank of the Tallahatchie River 

 contains an exposure of about 12 feet of black, very micaceous, sandy, laminated 

 clay, passing in spots into a soft micaceous sandstone. In the upper poriion of 

 this mass (which is overlaid by Orange S md capped with white siliceous sand- 

 stone — <fl58) there are large, flattened ferruginous nodules. 



The outcrops in ranges'] E. and 1 W., in Pontotoc and Lafayette, are merely 

 repetitions of those just mentioned, while R. 2 E. is occupied chiefly by the 

 Flatwoods. W. Marshall, and N. and W. Lafayette, exhibit chiefly the Orange 

 Sand strata, though here and there a deep well reaches the " black dirt," 

 yielding fetid water. In S. Lafayette, however, on the waters of the Yockeney- 

 Patafa, the lignite formation is well developed ; as also in Calhoun and E. 

 Yallabusha. 'i ho following section occurring on the Yockeney River, S. T 

 9, R. 3 W., will serve to characterize the strata of that region :
