The Cabbage Maggot, one of the most destructive pests 

 connected with the raising of cabbage, cauliflower, turnips 

 and radishes, has occupied much of our attention during the 

 season just past, and enough has been accomphshed this year 

 to outline our experimental work for next season, narrowing 

 it down to a few processes to be used, some on a small scale, 

 others on a large acreage, which we are confident will give 

 good results. In the mean while we have made some obser- 

 vations, a few of them new to science possibly, which we 

 include below. Many of these have a more or less practical 

 bearing on remedial treatment. 



The pest is so wide-spread and of such economic im- 

 portance that a colored plate precedes this article, illustrating 

 the appearance of the fly, its life history, showing the method 

 of egg-laying, and some of its enemies, for it must be known 

 it does not lead an existence entirely free from dangers of this 

 kind.
