lected and removed from the orchard. Treated bands should be removed, however, 

 before winter. In recent tests, a donnant application of an oil-pyrethrum 

 mixture has given good results in penetrating the overwintering cocoons and 

 killing the larvae. Prop poles may also be sprayed with this combination. 

 This treatment is still more or less experimental but it requires less time 

 and labor in scraping the trees and is one of the most promising of the re- 

 cent developments. A. I. Bourne 



Time Requ ired for Apple Scab In f ections 



How long must apple trees remain wet before scab infection takes 

 place? It depends upon the temperature. Only half as much time is required 

 at GO*^ as at 40°. And a light infection requires only half as much time as 

 a heavy infection. 0. C. Boyd presents the following data based on studies 

 in western New York:

Suggestions for Farmers Vfho Employ Boys 



Many boys are employed on Massachusetts farms during the summer vaca- 

 tion to help with the farm work. The testimony of many farmers is that with 

 proper guidance and handling most boys do good work and are an excellent source 

 of farm labor. This summer, more boys than usual will be employed by farmers 

 because adult workers are not available. Many farmers who have not hired boys 

 will do so for the first time this summer. 



Although boys usually do a good job on farms they present different 

 problems to the farmer employer than old-ir workers do. Boys are young and in- 

 experienced and require caroful supervision, patience and tolerance for best 

 results. Fanners who have fully realized these facts have had satisfactory 

 experiences in using boys.
