CLUB ROOT. 



The injury to the cabbage and turnip crops 

 attacked by club root may be considerable, some-

 less represented by millions of dollars. It is particu- 

 larly severe in the eastern portion of the United 

 States, but is not unknown in the west and south. 

 The following excellent account of this pest was 

 given by Dr. B. D. Halsted, botanist of the New 

 Jersey experiment station, in the columns of the 

 American Agriculturist:

 concerning club root. The name of the malady is 

 quite descriptive, for it is an affection of the roots, 

 which become much distorted. The roots may 

 begin to show enlargements while they are quite 

 small and before the plants are more than seedlings. 

 Thus cabbages while growing in the hotbed may 

 show unmistakable signs of "clubbing," followed by 

 a loss of vitality throughout the whole plant. The 

 affected parts soon begin to decay, becoming very 

 offensive, and, from places near by, other roots are
