At King's Bluff the middle and lower parts of the formation 

 are in contact. At the other bluffs of the river between King's 

 Landing and Selma the rock of the lower division is exhibited). 

 No. 32 (Table E) is of the rock at the steamboat landing in 

 Selma ; No. 33 of rock occurring near Selma ; No. 34 from Ca- 

 haba ; and No. 35 from Benton. 



These analyses show that the rock of this division is in gen- 

 eral too clayey for the best cement rock, but it might be mixed 

 with the purer limestone of Unicntown, or Demopolis in mak- 

 ing up a cement mixture. 



To summarize : From Demopolis eastward along the line 

 of the Southern Railway, by Van Dorn, Gallion, Uniontown, 

 Massillon, and thence by Martins and Milhous stations to White 

 Bluff, the white or Demopolis type of reck appears at the sur- 

 face in clean exposures at almost innumerable points, either 

 immediately on the railroad or at very short distance from it. 

 So far as the quality, quantity, and accessibility of the lime- 

 stone rock are concerned, -manufactories cf cement might be 

 located almost anywhere in this territory. From Demopolis 

 westward the same conditions prevail up the river to Epes, and 

 thence to Gainesville, beyond which point the white rock is to 

 the west cf the river at greater or less distance. 



East of Alabama River the outcrop of the cement rock is 

 crossed by the Louisville and Nashville Railroad (Repton 

 branch), as before stated, between Berlin and Pleasant Hill 

 stations. At Benton, on Alabama River, and on the railroad, 

 the limestone has the composition shown by analysis 35. 



On the Montgomery and Selma road, at the crossing of Pint- 

 lala Creek near Manack station, the limestone is exposed in the 

 creek banks and in the open fields, often with little or no over- 

 burden. In Table E are given analyses of a specimen from the 

 fields along the wagon road (No. 36), and from the creek bank 

 (No. 37.) 



On the main branch of the Louisville and Nashville Railroad 

 the white rock shows between the city and McGhees switch, and 

 an analysis of a specimen from McGhees is given (No. 38.) 

 Somewhat similar, but ratber better, is the limestone from H. 

 A. Jones, 8 miles south of Montgomery, shown in analysis 

 No. 39. 



Examinations have not been carried beyond Montgomery, 

 but it is known that the white prairie rock is crossed bv the 

 Central of Georgia Railroad between Matthews and: Fitzpatrick 

 stations, and there seems to be no doubt that along this stretch 

 of the road suitable rock will be found convenient to the line.
