HARPER: BOTANICAL CROSS-SECTION OF MissiIssipp1 387 
The typical Eocene country of northern Mississippi is moder- 
ately hilly, with reddish to yellowish clayey soil, some of it derived 
from the weathering of the Eocene strata, and some belonging to 
the much more recent Lafayette. According to Dr. Hilgard’s 
analyses these soils contain 0.05—0.09% of lime, 0.09-0.24% of 
potash, and 0.02-0.09% of phosphoric acid; which is a smaller 
percentage of the first two than in any other region here described. 
Like most other parts of northern Mississippi, it is now mostly 
under cultivation, and primeval forests are scarce. The same belt 
extends northward into Tennessee and eastward to South Carolina, 
if not farther.* 
The following plants were noted more than once in Webster 
and Montgomery Counties and the eastern half of Carroll on 
June 7th, or between Holly Springs and Hickory Flat on the 16th; 
a total distance of 77 miles.
