dering them unsalable and causing considerable

 the only satisfactory treatment. 



The ear worm is the only insect of importance. 

 This is a large larva usually entering the ear from 

 the tip and eating its w^ay about under the husk. 

 While only a comparatively small portion of the ear 

 is injured, the unsightly nature of the insect and its 

 injury destroys all desire for the ears so attacked. 

 This insect is more common toward the southern 

 limit of sweet corn culture, but is to be dealt with 

 from the Great Lakes southward and westward to 

 the Pacific Coast. No effective remedies are known. 



The most important varieties are Adams Early, 

 in reality not a sweet corn, but an extremely hardy 

 sort frequently planted for the first crop. White 

 Cob Cory and Golden Bantam are widely planted 

 early varieties of high quality. Cosmopolitan, Ken- 

 dal's Giant, Country Gentleman and Stowell's Ever- 

 green are varieties generally grown as a mid-season 

 or late crop. Columbus Market is a variety grown 

 extensively in the vicinity of Columbus, O., de- 

 serving of wider distribution. It is a mid-season 

 sort with unusually large ears and broad, deep 

 grains of high sugar content.

Cress belongs to the mustard family and is used 

 largely for salads, garnishes and as greens. There 

 are three common forms sometimes found in cul-

 commercial importance. The demand for this plant 

 is constantly increasing, and it finds its chief use
