 SECTION AT PRICE'S OLD MILL, ON THE YOCKENEY RIVER. 



Lower down, on Dr. John Taylor's land, S. 30, T. 9, R. 3 W., the lignite 

 crops out, 2 to 3 feet thick, a little above the bad of the river, which is formed 

 by a tenacious blue clay — probably No. 1 of See's 18 and 19. 



173 Higher up, also, on the heads of the Yockeney, lignite is found. s A bed 

 said to be 8 feet thick occurs at Mr. Vineyard's, S. 1, T. 10, R. 1 W. ; it is found 

 in wells in T. 9, R. 2 \V., and also on branches of Potlockney Creek, in T. 10, 

 R. 2 W , wherd I have had an opportunity of examining it. It crops out in 

 bluffs and gullies on Hughes' branch, on S. 8, T. 10, R. 2 W., overlaid by some 

 30 feet (as far as visible) of sharp yellow sand with ferruginous veins. The 

 sand, which is evidently a member of the lignite group, occurs in many bluffs 

 in the neighborhood, and sometimes contains impressions of leaves In a branch 

 near Mr. S. Ragland's, on S 9, T. 10, R. 2 W., there is an outcrop of great 

 interest, of which Diagram No. 5 will convey an idea. 



The stratum of greenish yellow sand at a contains impressions of leaves, 

 chiefly of a Cinmmomum not unlike the Sassafras, c is a bed of yellowish 

 white clay of irregular, or thickly laminated cleavage, containing numerous 

 leaves of a Sxbal, also a variety of other, chiefly dicotyledonous plants, among 

 which a Quercus and Mcusf, which seem to be identical with species found in 

 the red shale of Tippah. In the yellow sand at d, immediately overlying the 

 clay stratum, there occur large billets of silicified wood, the interior of which 

 is black. The bed of the branch on the N. half of the bluff, is formed by blue 

 clay e, of massy cleavage, similar to No. 1 of See's 18 and 19, which appears to 

 underlie horizontally. The N. dip of the strata of the outcrop seems, therefore, 

 to be owing to a fault or landslide. The yellow fossiliferous sand found in other 

 localities in the vicinity, is high above the level of the leaf bearing clay stratum 

 of this diagram. 



In the sands just mentioned, there frequently occur ferruginous, rust-colored 

 stripes, which at first sight appear to be stratification lines, since they very 

 commonly run parallel to the latter. Sometimes, however, these stripes exhibit 

 fanciful vrndu'-ations and contortions, and would lead the observer to suppose
