 they attack; an application of Paris green 

 dusted over the plants is very destructive to 

 them, but being so dangerous a poison, we 

 recommend hand-picking and burning of the 

 bugs in preference. The application of 

 tobacco-water, whale-oil soap, etc., is use-

 plants. 



ROSE SLUG. These slugs are the larva of 

 a saw-fly, called by Harris Tdandria Rosa, 

 an insect about the size of a common house-

 May and June. The female flies puncture 

 the leaves in different places, depositing their
