 together and the cabbage, coming on later, has fewer 

 enemies. There are other methods of control. One of these

 storage at so low a temperature that the destructive insects 

 will not develop. There is no virtue in any method unless 

 it be applied with knowledge of habits and life histories. 

 There is now available in government publications* a vast 

 store of such knowledge, and it is furnished freely to all who 

 apply for it. 



First, find out what your pest is. If you cannot learn this 

 from your books or from some local person who knows, then 

 send specimens for naming as directed on page 207. Then 

 for specific information as to how to control this pest, apply 

 to the Bureau of Entomology, U. S. Department of Agri- 

 culture, Washington, D. C, or to Entomologist's Office of 

 the Department of Agriculture of your own State.
