EtKEL.J ALABAMA. 81 
Below Monroe station, near Drewry, on the Repton Branch, this 
oad crosses the line of outcrop of the chimney rock, which at a 
lumber of points in the vicinity of Drewry lies within easy reach of 
ransportation. 
A few miles below Drewry, at Manistee Junction, there is a fine 
xposure of Grand Gulf clays in railroad cuts both north and south of 
he station. 
Analysis is given (No. 59, p. 84) of the clays from three horizons in 
hese cuts, from which their suitability for admixture with the lime- 
tone may be determined. 
The chimney rock may be found at many points below Evergreen, in 
he vicinity of Sparta and Castleberry stations. There are many bluffs 
if this rock on the banks of Murder Creek in this vicinity, and there are 
Several quarries from which the stone has been obtained for building 
mrposes within short distances of the railroad line. At the foot of 
aliaferros Heights the limestone forms high bluffs on the creek, at 
Mis Williams Spring there are bluffs with the soft rock at the base 
nd the hard horse-bone rock at the top, and on the creek bank a few 
i undred yards away is one of the quarries mentioned above. In fact, 
i ie localities where the rock may be found within convenient distance 
f the railroad and in a position favorable to cheap quarrying are 
\ umerous in all this region. No clays were seen except the usual 
i 3sidual clays from the decomposition of the limestone and a clay 
| ccurring close to Evergreen in the pits of Wild Brothers. Analyses 
i 0, 41, and 42 will show sufficiently well the character of the limestone 
« i this section. 
These Evergreen occurrences have attracted attention because of 
io leir location on the line of a great railroad system within short dis- 
Lnce of tide water. 
in I Farther east this limestone formation extends across Alabama and 
in ito Georgia and Florida, but as there is no north-south railroad east 
es f the Louisville and Nashville at this time, the investigations have 
.nj Dne no further. 
To summarize: While the St. Stephens limestone outcrops across 
ie State from the Mississippi line to the Chattahoochee River, often 
cupying broad belts, attention has been cencentrated on those locali- 
3S which lie upon navigable streams or upon railroad lines terminat- 
g in Gulf ports. As compared with the middle division of the Selma 
lalk, this limestone is more uniform in composition, higher in lime 
ntent, softer and more easily quarried and crushed, and in geograph- 
al position many miles nearer the Gulf. Its thickness, on the other 
r;« md, is much less, although sufficient to supply an indefinite number 
oil f cement plants with raw material for cement.
