DESCRIPTION OF PLATE XXIII. 



This plate shows the condition of the trees in the experiment block of the Rio 

 Bonito orchard at the close of the spray work in the spring of 1895. The row of 

 trees at the left has been sprayed; that at the right has been left unsprayed for com- 

 parison. The first 10 trees on the left have been treated with a spray containing a 

 moderate amount of lime; the second 10 in the same row were treated with a spray 

 containing more lime, and they are much whiter than those in the foreground. 

 Each row of 10 sprayed trees on the left and the cijrresponding row of 10 unsprayed 

 trees on the right constituted an experiment. The uniformity in the size of the trees 

 in these experiments is here shown to advantage. It should be noted that the buds 

 are still closed, while the spraying is completed.
