STONE FRUITS: THE CHERRIES 



Varieties 



Let pupils tell where there are sweet and sour cherry 

 trees growing in the district. 



How do the two trees differ in manner of growth? 



See how much can be learned about the names of the 

 varieties of each type that are grown successfully. Make 

 a temporary blackboard Hst under these headings: 



Sweet or Mazzard Sour or Morello 



Enemies 



Make a map of the district and mark on it every 

 locality where pupils find that black knot is growing 

 on wild cherries, cultivated cherries, or plums. 



Get each pupil to agree to destroy the black knot on 

 his own farm or home grounds. 



Request the highway commissioners to destroy it 

 along the highways.
