INSECT PESTS AND DISEASES 63 



seem at first thought. Twice a day, for a few 

 days, may actually make a finish of them straight 

 off for the season. Perhaps a second invasion 

 may occur. After another campaign of the same 

 thorough kind, however, nothing more is likely 

 to be seen of them, except, maybe, a few stragglers.

 around the stem, just below the surface. In the 

 middle of the day, you will find them underneath 

 the leaves, many of them on the cool ground. At

 After all that has been done, it may be neces-

 are only slightly poisonous. Hellebore is stronger
