tion and Jackson, and no doubt it occurs from Glendon up to 

 Suggsville station, within convenient reach of the railroad. At 

 Suggsville station the same rock occurs along the road leading 

 from station to the town. This place is within a short distance 

 of the railroad. 



Between Suggsville and Gosport, the country rock is the St. 

 Stephens limestone, but no particular attention was given to it 

 for the reason that no railroad crosses the county along this 

 line. 



Along Alabama River. At Perdtue Hill the St. Stephens 

 rock outcrops near the base of the hills which descend to the 

 terrace on which the town of Claiborne stands. The bluff at 

 Caliborne Landing shows near the summit the calcareous clay 

 or clayey limestone which lies at the base of the St. Stephens 

 formation, and which is generally thought to be the equivalent 

 of the Jackson group of the Mississippi geologists. It is quite 

 possible that this rock, where it occurs in sufficient quantity, 

 may be suitable for cement making,, since it has a composition 

 not far different from much of the Rotten limestone or Selma 

 chalk. No investigations have yet been made concerning it, 

 for the reason that there are comparatively few points where it 

 appears in adequate thickness and in favorable localities as re- 

 gards transportation. 



At Marshall's Landing, just above the mouth of Randon's 

 Creek, is the first exposure of the chimney rock along Alabama 

 River. This occurs at the top of the bluff. It has the usual 

 covering of residual clay, and the analyses presented (3 of Table 

 F, and 7 of Table G,) will show the composition of the two. 

 Below the orbitoidal or chimney rock at Marshall's there are 

 20 feet or more of a porous limestone, the analysis of which is 

 given in Table F, No. 4. In the same bluff there are beds of 

 calcareous clay which might possibly be used in mixing with 

 the limestone. At the landing these wouia be difficult to quarry 

 because of overlying strata, but they would certainly be found 

 without cover along the bluffs above Marshall's if they should 

 prove of value. 



From Marshall's down to Gainestown Landing the river 

 bluffs show beds of the limestone at numerous points. At 

 Gainestown, the topmost bed of the St. Stephens, the hard crys- 

 talline limestone occurs not far above the water level in the 

 river. This stone has been cut and polished and proves to be
