COTTON CULTIVATION 



353 



Therefore, the turn-plow should be used for barring off 

 cotton only under special conditions; for example: — 



(1) When grass has become too large to be easily killed 

 by " scrapes " or by other shallow-working implements. 

 In this case the best means of killing the grass may be by 

 burying it for a number of 

 days, as is done by the 

 moldboard plow. 



(2) The deep tillage, such 

 as that given by the turn- 

 plow, may sometimes be de- 

 sirable on clay soils prepared 

 early and subsequently 

 very greatly compacted by 

 rains, hence needing stirring 

 after the plants come up. 



A widely used and gener- 

 ally satisfactory implement 

 for this cultivation or scrap- 

 ing is a narrow sweep or 

 scrape, especially when 

 equipped with a fender. 

 Such a cultivating imple- 

 ment may be one of several 

 similar points attached to 

 a two-horse cultivator or 

 to a one-horse cultivator, 

 or it may be the sole point 

 on an ordinary cultivating 

 "stock," or plow frame 

 (Fig. 151).
