lirnc even improves by being thus kept for a time ; but the process is not advis- 

 able with very impure lime, such as that made of the .Rotten Limestone (H 149). 



311. Most of the hard limestone occurring in the Brandon 

 neighborhood is of the same character as that of which the analysis 

 is given above. 



Besides being found on the belt mentioned above (If 309), it occurs also due 

 S. of Brandon, near Dr. Parker's, in a little branch on S. 27, T. 5, E. 3 E. ; the 

 ledge is not, however, as thick as the one at Yost's kiln, and belongs to a lower 

 level. At a lower level still, on Richland Creek, S. 34, T. 5, 11. 3 E., there is an 

 outcrop similar to the one mentioned. These strata do not, however, appear to 

 be always continuous, so that the rock is not necessarily found in one hill at the 

 same level at which it occurs in the one opposite. Limestone precisely similar 

 to that at Yost's kiln, was found in Mr. Ware's well, E. of Brandon, at about 

 40 feet ; and again, we find it overlying the marl at Dr. Quin's (see above, H285). 

 Dr. Q. has used the rock for lime-burning, and finds it to produce an excellent 

 article. 



312. The same limestone occurs, no doubt, further on in a S. E. 

 direction, about Polkville. It is found again in the neighborhood 

 of Raleigh, and crops out on the slopes of the ridges, towards 

 Shongalo Creek. N". E. of Raleigh ; the ledges so far as I have 

 seen, are of less thickness than in Rankin, and on the whole, less 

 pure — the marl character prevailing over that of the limestone. 

 On the ridge between Shongalo and Bowland's Creek, the rock 

 also crops out, giving rise to terraces on the hills ; that which 

 I have seen there, is very rich in greensand grains, and would 

 probably answer better for agricultural, than for architectural 

 purposes. 



313 1 . I am not aware whether or not any hard limestone occurs 

 on the territory of the Vicksburg Group in S. Jasper, but it is 

 very likely that such is the case, for we see it in Wayne county, if 

 not as abundantly, or generally speaking, of equal purity with 

 that of Rankin and Hinds, nevertheless affording abundant oppor- 

 tunity for the manufacture of quicklime, of good quality. Here as 

 elsewhere, the hard blue or gray limestone is to be preferred to 

 any of the softer and yellowish materials ; nevertheless, the pure 

 white marls (1T294) might, if necessary, be used for the purpose. 

 Blue limestone is found on the Chickasawhay River, at, and for 

 some distance above, Dr. E. A. Miller's place, near Waynesboro' ; 

 on Limestone Creek, both at its mouth and further up : on Yellow 

 Creek, in ledges of inconsiderable thickness, interstratified with 

 blue marl ; on Cakchey's mill Creek, and others. It is also found 

 on the Buckatunna, S. E. of the localities mentioued. The soft 

 yellowish limestone underlying the prairies and forming bald hill- 

 tops, in this region, is generally better suited to agricultural, than 

 to architectural purposes. 



313°. Building Stoxes. — With the exception of the limited 

 deposits of variegated aluminous sandstone occurring at Reeve's, 

 and on Muddy Creek, in Tippah (1168), no hard rocks but those 

 belonging to the Orange Sand (111, 56) occur in quantities useful 

 for building purposes, on the territory of the Northern Li^mtic 

 formation.
