THE DISEASES OF THE COTTON PLANT,

Many of the most experienced planters attribute

 leaves, when first attacked, appear rather more yellow 

 than the rest, with red spots on the surface. These 

 leaves turn more yellow and red every day, until the

 assumes a different appearance, and is termed the 

 "red" or "black" rust, as the case may be. The

 black rust, and the bolls themselves, shrivel up and
