FAKM PRACTICE IN THE CULTIVATION OF COTTON. 17 
Land is plowed deeper in this division than in the other areas 
studied. This is probably due to the fact that the soils are pre- 
dominantly of a sandy type, and soils of this texture are, generally 
speaking, broken deeper than clay soils. 
In this division it will be noted that more tillage is given after 
plowing and before planting. This is due primarily to the use of a 
fertilizer distributor, which is not so extensively employed in other 
divisions. 
The Intermediate areas include Giles County, Tenn., Monroe 
County, Miss., St. Francis County, Ark., and Lincoln Parish, La. 
In each of these areas there are varying conditions. Part of the 
land in each region is rolling and rough, with irregularly shaped fields 
and small farms, and part is broad level bottom land divided into 
large farms. The upland rolling farms are usually worked by the 
owners or by tenants who supervise their own work. Crop yields 
are not so good as on the bottom-land farms, which are often very 
large and are usually worked by tenants under 'the supervision of the 
owner or a hired manager. 
Little uniformity is found in these areas with regard to general 
conditions and tillage practice. 
The Southwestern division includes Texas and Oklahoma. Five 
areas were surveyed in this division. Here the predominating soil 
type is a clay loam. Most of the farms are operated by the owners 
or by tenants who supervise their own farming. Heavier teams and 
implements are employed both for preparing the land and for culti- 
vating the crop. The land is comparatively fertile, and little or no 
commercial fertilizer is used. The crop yields are probably gov- 
erned here more by climatic conditions than by soil fertility or tillage 
practice. 
The depth of breaking land and the amount of tillage given both 
before and after planting are about the average, yet crop yields are 
below the normal average for other areas studied. This is prob- 
ably due primarily to scant rainfall. 
GENERAL FARM PRACTICES AND CONDITIONS. 
SURVEY IN PEMISCOT COUNTY, MO. 
Pemiscot County is located in the extreme southeastern part of 
Missouri along the Mississippi River. The tillage records for this 
county (Table XI) were taken near Caruthersville. This is a typical 
Delta region. The soil and subsoil are a silty clay loam and very 
fertile. No commercial fertilizer is used, and stable manure is not 
considered valuable. The country is exceptionally flat, and the soil 
is such that no surface or tile drainage is required. The excess 
water is collected by broad open ditches and runs into central canals, 
which are dug by the county.
