whom this striking case was named said that they had 

 seen similar results from lime spraying. ]VIr Hooper's 

 explanation is that the lime coats over the eggs of the 

 pests, and extracts moisture from them, thus destroying 

 their vitality. Lime-wash must be strained before 

 it is put into a spraying machine, and it is important 

 to do the work only in dry weather, and to cover 

 every twig. If rain occurs before the stuff has dried 

 thoroughly on the trees, the lime is easily washed off ; 

 but it sticks on well after bemg dried. In the case under 

 notice the spraying was done as soon as there was any 

 sign of an attack by birds upon Plum buds. Apart 

 from this attack, however, just before the buds approach 

 the bursting stage is probably the best time to apply the 

 lime-wash. "Southern Grower." p. 414, 21. 6. 13. 



It is wise to spray with some insecticide of moderate 

 strength, p. 436, 28. 6. 13. 



Red spider, syringe the foliage constantly with water, 

 to which has been added a little quassia extract. 



If the cherries are infested with black fly, the affected 

 shoots should be cut away and the trees syi'inged with 

 an insecticide. After each appUcation a syringing 

 of clean water should follow. This method will be 

 found to be a great improvement on the old plan of 

 applying tobacco powder, p. 437, 28. 6. 13. 



Soft soap, one quart, in one gallon of boiling water. Add 

 one pint crude carbohc acid and dilute with 30 times 

 its bulk of water. Syringe the ground around the 

 attacked plants, p. 444, 28. 6. 13. 



Spraying with paraffin emulsion is recommended. Soft 

 soap and quassia extract may also be tried, p. 5, 

 5. 7. 13. 



If there are bad infestations the growths most affected 

 should be cut off and burned and the tree syringed 

 afterwards, first with an insecticide, then with clean 

 water, p. 9, 5. 7. 13. 



Next winter drench the trees thoroughly with soft soap 

 and paraffin emulsion, p. 20, 5. 7. 13. 



The foliage should be syringed thoroughly or washed by 

 means of the garden engine two or three times a week. 

 This will cleanse the leaves of insect pests, p. 29, 

 12. 7. 13. 



Pinch the maggots in the leaves and remove the leaves. 

 . . .Afterwards you can make the plants distasteful 

 to the flies by syringing them with quassia extract, 

 or you may scatter soot, lime, etc. p. 60,
