» the summit, where it has a capping of plastic clay only. The char- 
ter of the Limestone from this locality is shown in analyses 28 and 29. 
At Elm Blurt', as has already been shown, the upper and middle 
visions of the formation are in contact. At Kings Bluff the middle 
d lower parts of the formation are in contact. At the other bluffs 
the river between Kings Landing and Selma the rock of the lower 
rision is exhibited. No. 31 is an analysis of the material as exposed 
Cahaba; No. 53 of the river bluff at the steamboat landing in Selma, 
d No. 32 at Benton. 
To summarize: From Demopolis eastward along the line of the 
mthern Railwa} T , by Van Dorn, Gallion, Uniontown, Massillon, and 
ence by Martins and Milhous stations to White Bluff, the white or 
3mopolis type of rock appears at the surface in clean exposures at 
nost innumerable points, either immediately on the railroad or at 
irery short distance from it. So far as the quality, quantity, and 
cessibility of the limestone are concerned, manufactories of cement 
ght be located almost anywhere in this territory. From Demopolis 
stward the same conditions prevail up the river to Epes, and thence 
Gainesville, beyond which point the white rock is to the west of 
b river at greater or less distance. 
East of Alabama River the outcrop of the cement rock is crossed 
the Louisville and Nashville Railroad (Repton branch), as before 
ted, between Berlin and Pleasant Hill stations. At Benton, on 
abama River and on the railroad, the limestone has the composition 
3wn by. analysis 32. 
On the Montgomery and Selma road, at the crossing of Pintlala 
eek near Manack station, the limestone is exposed in the creek 
ks and in the open fields, often with little or no overburden. On 
^e 83 is given an analysis of a specimen from the fields along the 
gon road (No. 33) and from the creek bank (No. 34). 
3n the main branch of the Louisville and Nashville Railroad the 
ite rock shows between the city and McGhees switch, and an 
ilysis of a specimen from McGhees is given (No. 35). 
Sxaminations have not been carried beyond Montgomery, but it is 
own that the white prairie rock is crossed by the Central of Georgia 
Jilroad between Matthews and Fitzpatrick stations, and there seems 
1 be no doubt that along this stretch of the road suitable rock will 
found convenient to the line. 
ST. STEPHENS OR VICKSBURG LIMESTONE. 
GENERAL DESCRIPTION. 
Che St. Stephens or White limestone formation of the Alabama 
tiary, which includes the uppermost of the Eocene strata, is in 
| leral equivalent to the Vicksburg and Jackson limestones of the 
,1 ssissippi geologists. 
n Alabama St. Stephens exhibits three rather well-defined phases,
