While the use of the turn-plow in this first cultivationby rows is perhaps more coininon than that of any other.

(2) These narrow high ridges may crunil)le, pulling theplants down, if heavy rains occur. (3) The deep plowing by the turn-plow cuts many roots. COTTON CULTIVATION 353 Therefore, the turn-plow should be used for barring offcotton only under special conditions; for example: — (1) When grass has become too large to be easily killedby scrapes or by other shallow-working this case the best means of kilhng the grass may be byburj^ng it for a number ofdays, as is done by themoldboard plow. (2) The deep tillage, suchas that given by the turn-plow, may sometimes be de-sirable on clay soils preparedearly and subsequentlyverj greatly compacted byrains,hence needing
