f here, is a change in the character of timber as soon as the Selma 
|a is reached. Short-leaf pine, which occurs so abundantly in the 
I twoods, is wanting except in the old "turned-out land." Black 
is the principal timber in the Selma chalk. Some post oak and 
vory occur. The pine is wanting at a distance of 2 miles east of 
oba, which would perhaps bring the contact between the Selma 
Midway one-half mile west of the Selma outcrop. 
Vo miles east of Scooba and one-half mile south is another outcrop 
imestone, more sandy than .that 2£ miles east of Scooba. This is 
haps of Ripley age. 
between Portersville and Oakgrove, in southern Kemper County, 
the west side of Pittiefaw Creek, the Lagrange hills begin and 
end westward. On land belonging to Mr. M. L. Nailer a bed of 
lite, reported to be 4 feet thick, has been opened, 
ucarnooche Creek marks the west edge of the Midway group from 
miles due east of Dekalb to about 3 miles north of Oakgrove. 
re the Porters Creek area widens and its west edge swings in to 
hin 2i or 3 miles east of Oakgrove, then follows a southeasterly 
action and crosses the Kemper and Lauderdale County line about 
miles west of the State line. 
)n the west side of Quilby Creek, where it runs south along the 
te line, 7 miles east of Sucarnooche, the Selma chalk forms a small 
ff, The prairie soil extends back for 2 miles farther west. On the 
b side of the creek, about 100 yards in Alabama, the Selma chalk 
ms a bluff a little higher than on the opposite bank in Mississippi, 
re what is taken to be the top of the Selma chalk is found. The 
of the bluff is capped by a coarse-grained sandstone, cemented by 
e carbonate. In it are lime concretions the size of a closed hand, 
'he upper beds of the Selma chalk also appear in the bluff on the 
t side of Quilby Creek, 7 miles east of Sucarnooche. 
\n outcrop of Selma chalk shows on Scooba and Fox Prairie road 
pre it crosses Bodea Creek, about 2 miles west of the State line. 
k sample collected from this outcrop by Mr. Crider was analyzed 
jjjbhe laboratory of the United States Geological Survey by W. S. 
Neil.
