PLATE 33 



A. — Plantation at Whitesbog, N. J., for the testing of blueberry hybrids. From 

 very carefully selected wild blueberry plants hybrid seedlings are raised in the green- 

 houses of the Department of Agriculture at Washington. In order to bring them into 

 fruit under favorable outdoor conditions so that selections of the best hybrids can be 

 made for further propagation, the young seedlings are sent to a plantation at Whitesbog, 

 4 miles east of Browns Mills, in the pine barrens of New Jersey. In the photograph 

 2-year-old hybrids are shown at the right and 3-year-olds in the row at the left. 



B. — Four-year-old blueberry hybrid in full fruit. This illustration shows the 

 vigor, beauty, and productiveness of a hybrid blueberry bush when it is given the 

 proper and peculiar conditions which by its nature it requires for successful growth. 

 From a ^3-acre patch of hybrid bushes a yield of berries was secured in 1919 at the rate 

 of 96 bushels per acre. They sold at a little over $10 a bushel, bringing gross receipts 

 at the rate of $966 per acre. In 1920 this planting yielded at the rate of 117 bushels 

 per acre, which sold at a little less than $11 a bushel, yielding gross receipts at the 

 rate of $1,280 per acre.
