Farther  to  the  east  this  limestone  formation  extends  across  Alabama 
and  into  Georgia  and  Florida,  but  as  there  is  no  north-south  railroad 
east  of  the  Louisville  and  Nashville  at  this  time,  the  investigations 
have  gone  no  further. 
To  summarize:  While  the  St.  Stephens  limestone  outcrops  across  the 
State  from  the  Mississippi  line  to  the  Chattahoochie  River,  of  ten  occu- 
pying broad  belts,  attention  has  been  concentrated  on  those  locali- 
ties which  lie  upon  navigable  streams  or  upon  railroad  lines  terminating 
in  Gulf  ports.  As  compared  with  theDemopolis  division  of  theSelma 
chalk,  this  limestone  is  more  uniform  in  composition,  higher  in  lime 
content,  softer  and  more  easily  quarried  and  crushed,  and  in  geograph- 
ical position  many  miles  nearer  the  Gulf. 
Its  thickness,  on  the  other  hand,  is  much  less,  although  sufficient  to 
supply  an  indefinite  number  of  manufactories  with   raw  material  for 
cement.
