96 THE APPLE-TREE 



properly timed, may suffice also for the codlin-moth. 

 As the fungus may attack the flower-stems and kill them, 

 so is the first application made when the flower-buds 

 open and the stems begin to separate, but before the 

 flowers expand ; the operator has a period of one to three 

 days in which to spray. A second spraying is given just 

 after the blossoms fall, as for codlin-moth ; if the season 

 is wet, a third application may be made ten to fourteen 

 days later ; if the fungus seems to spread, a fourth spray- 

 ing may be applied in midsummer. These sprayings, 

 variously modified, control not only the codlin-moth and 

 the scab fungus but also scale, blister-mite, plant-lice, 

 leaf-roller, case-bearer, bud-moth, red-bug and others. 



In the tropics one sees trees bearing great burdens 

 of orchids and bromeliads and ferns and mosses, and one 

 wonders at the strange and exuberant population. Yet 

 here is my apple-tree supporting epiphytes and parasites 

 and insects, protector and nurse of a goodly company; 

 and birds nest on the branches thereof.
