 Elberta peaches picked the same day in the state experiment orchard 

 at Vineland. The fruits in the upper portion of the picture were 

 taken from a highly fertilized and rapidly growing tree, while those 

 in the lower portion of the picture were taken from a tree checked

in growth by girdling. The latter will mature into larger specimens. 

 Attention should be called to the fact that a general check to the 

 whole tree, as the effect of a drought, for example is entirely differ- 

 ent from a check in the processes of translocation of foods due to 

 winter injury and other factors. The orchard at Vineland with its 

 numerous fertilizer plots and trees of different ages offered excep- 

 tional facilities for such observations. It should be remembered that 

 the number of the fruits on the tree and the supply of moisture are 

 always factors in determining the size of the fruit.
