12 of. Table G) show the chemical character of the cement man- 

 ufactured at Demopolis. 



At Van Dorn station the white rock outcrops in the fields 

 over considerable territory, (Plate XIII), and just east of the 

 station there is a deep cut through it. Analyses from about 

 Van Dorn show sufficiently well the character of the material 

 at these points (analyses 21 and 22 of Table E.) 



About Uniontown the bare rock is exposed at numerous 

 points, and the advantages of this place for the location of man- 

 ufacturing plants seem to be very great. Specimens have been 

 taken from the Bradfield and Shields places, west of the town, 

 and from the Pitts place east, and from a point south of the 

 town along the McKinley road. Other specimens have come 

 from plantations near the road for several miles eastward! and 

 the analyses are appended (analyses 23, 24, 25, 26, 27 and ~ 



The composition of the res^aual clay overlying the limestone 

 at the Pitts place is shown in analysis No. 2 of Table G, and 

 that of a similar clay from the "Graveyard Hill" on the Mor- 

 gan place, by analysis No. 3 of same table. 



South of Massillon, near the crossing of the Southern and 

 Louisville and Nashville railroads, in the vicinity of Martin's 

 station, the white rock showis in numerous exposures through 

 the fields, making a country somewhat similar to that about 

 Unicntown. At many points the rock has no overburden, and 

 is admirably adapted to cheap quarrying. On the banks of 

 Rogue Chitto Creek, near Martin's station, on the Milhous 

 place, the rock is exposed in a bluff with a bed of plastic clay 

 overlying, but here it is below a considerable thickness of red 

 loam and sandis of the Lafayette formation. The character of 

 the rock at Milhous station, west of Martin's, may be seen 

 from the analysis No. 29, Table E. 



The same rocks make the great bluff of White Bluff, on Ala- 

 bama River, (Plate XIV.) Specimens were selected from 

 this bluff at two points one about halfway down the bluff, the 

 other twenty feet lower. Generally there is a capping of the 

 red loam and sands of the Lafayette over the limestone, but 

 near the upper end of the bluff the white rock extends to the 

 summit, where it has a capping of plastic clay only. The char- 

 aster of the limestone from this locality is s'hown in analysis 30, 

 Table E, and that of the overlying residual clay in analysis 4 of 

 Table G. 



At Elm Bluff, as has already been shown, the upper and 

 middle divisions of the formation are in contact. (Plate XV.)
