the land. Especially is this true when corn follows corn or cotton. 
For such work a 3-horse or -1-horse team is used and the plow em- 
ployed has a broad shovel which breaks practically all the row. Xo 
difference in the } 7 ield is noted from the different methods of prepar- 
ing the land. About 90 per cent of the corn is listed and planted in 
drills 3 to 3^ feet apart with one stalk every 18 inches in the drill. 
After planting, a spike-tooth harrow is frequently used just as 
the corn comes up. A disk cultivator especially designed for culti- 
vating listed corn is extensively used for the first cultivation. The 
1-row cultivator of this t} 7 pe (fig. 36) is constructed on a sled which 
straddles the corn row and protects the corn plants from being cov- 
ered with dirt from the disk cul- 
tivators which run on either side 
of the row. The 2-horse 4 and 
6 shovel cultivators and disk cul- 
tivators are used for the later 
cultivations. A few farms use 
a 1 -horse 5-shovel cultivator. 
Usually three or four cultiva- 
tions are given. After the corn 
gets too high to cultivate, some 
farmers will, with one horse, 
drag a mowing-machine wheel 
between the rows, 'which destroys 
nearly all the small weeds and 
forms a shallow dust mulch. 
Practically no cover crops are 
grown and no commercial fer- 
tilizer is used. 
The yellow dent varieties of 
corn are principally grown. 
The most prevalent weeds are 
smartweed, crab-grass, ragweed, bull nettle, artichoke, and Johnson

SURVEYS IN PIKE COUNTY, ALA. 
The tillage records for Alabama (Table XXVIII) were taken in 
Pike County near Troy. The soil in this region is of a sandy or 
sandy-loam type, usually dark red in color, and underlain with a red- 
dish sand-clay subsoil. The land is very irregular and in some 
places extremely rolling. Drainage is principally obtained by means 
of numerous terraces, which divide the fields into small, irregular- 
shaped areas. These terraces are usually about. 25 yards apart and 
are so constructed that they can not be worked over. On most of 
them Bermuda grass is grown to prevent erosion.
