Fic. I.—PLANTATION OF 2-YEAR-OLD AND 3-YEAR-OLD HYBRID BLUEBERRIES 
| AT WHITESBOG, N. J. 
The soil is a white sand mixed with upland peat and is strongly and permanently acid. 
The rows are 8 feet apart, the plants 4 feet apart in the row. The row at the left consists 
of 3-year-old plants; the others are 2 years old. Each of these plants is a seedling hybrid 
and although of carefully selected parentage its own qualities can not be known until i 
fruits. The photograph was taken August 2, 1917.

26, 1920. The plants in the left-hand row are now 6 years old, the others 5. In the back- 
ground a blueberry packing shed has been erected. At the right in the background are 
| shown the gauze screens that are placed over selected bushes which are to be kept under 
special observation.
