A QUART OF SELECTED ElELD-GROWN BLUEBERRIES 



This illustration shows, in its natural size, a quart box of selected blueberries grown in 

 the plantation of Miss Elizabeth C. White, at Whitesbog, New Jersey, in a peaty, well-watered, 

 pine-barren soil. There are thousands of acres of such soil in the southeastern quarter of 

 New Jersey now lying unused for any agricultural purpose. 



may merely be stated that after each of 

 the essential principles was clearly under- 

 stood special methods for rooting blue- 

 berry cuttings were perfected without 

 serious difficulty and are now in practical 

 operation in the field. 



Reference has already been made to 

 the breeding experiments aimed at the 

 production of new and superior varieties 

 of blueberries. In the course of these 

 experiments one fact turned up which 

 merits comment here, because to its cu- 

 rious interest is added its great practical 



importance in the actual field culture of 

 the blueberry. 



An attempt was made to ascertain 

 whether an especially fine blueberry va- 

 riety could not be made to come true 

 from the seed by pollinating flowers of 

 the individual plant with its own pollen, 

 just as has commonly been done in the 

 breeding of choice varieties of vegetables. 

 From these self-pollinations, however, 

 few berries and seeds were secured. 



In all cases, although the pollinations 

 were made very carefully by hand, the
