THE CAHABA BASIN. 
The Cahaba basin is situated west and northwest of the 
Helena basin, the interior fault vertical coal measures sep- 
arate the two. 
It is bounded on the southeast side by the interior fault, 
on the southwest end by the Gould basin, on the northwest 
side by the sub-carboniferous measures of Shades Valley, 
and on the northeast end by the Acton basin. The bound- 
ary of the basin is as follows: Commencing on the South 
and North Alabama Railroad, about forty yards south of 
bridge 70, or Carr bridge, thence southwest along the edge 
of the fault measures, leaving the Holt house to your right, 
continuing southwest along the edge of the interior fault, 
passing close by the northwest corner of section 16, through 
the middle of section 17 to the middle of the southwest 
quarter of section 17, thence northwest, crossing Cahaba 
river and following up Lainey branch to its head, near the 
northwest corner of section 7, thence over Shades moun- 
tain to the base of the Millstone Grit, thence northeast 
along the base of Millstone Grit through section 6, crossing 
the South and North Alabama Railroad at Brock’s Gap, 
near the middle of section 32, continuing on northeast to 
that part of section 28 opposite the head of Bailey’s branch, 
thence southeast down Bailey’s branch, crossing the 
Cahaba river in the south end of section 34, to the vertical 
coal measures of the interior fault, thence southwest along 
the northwest edge of the interior fault to the point of be- 
ginning on the South and North Alabama Railroad, near 
the Holt house. 2 ~

called the Montevallo and Elyton road, where, thirty-five 
years ago, Jemison and Powell used to run their stage.
