400 Report of the Horticultural Department of the 



So far as the influence of spraying in bloom upon the yield is 

 concerned it is evident that this test with the Pumpkin Sweet 

 is inconclusive, because there was very little fruit produced by 

 either the treated or the untreated trees. 



Three trees of Baldwin were sprayed in bloom and three corre- 

 sponding trees were not so sprayed. On August 16 the follow- 

 ing notes were made. 



Row 3 — sprayed m hloom. — Tree 5: Lower limbs except on 

 west and north are well loaded. The rest of the tree has a fair 

 crop. Tree 6 : A good crop and quite evenly distributed. Tree 7 : 

 A fair crop on south and east parts of the tree. The rest of the 

 tree has a light crop. 



Row 4 — ^ot sprayed in Uoom. — Tree 5: Except on the north- 

 west the tree is well loaded and the crop quite evenly distributed. 

 Tree 6: A fair crop and quite evenly distributed. Tree 7: A 

 light crop. 



On account of the variability in the yield of the different Bald- 

 win trees which received the same treatment a larger number of 

 trees should be tested in order to get satisfactory evidence as 

 to the effect of the treatment on the yield. 



EXPERIMENT AT HALLS CORNERS. 



Spraying in bloom was tested on Baldwin and Rhode Island 

 Greening trees in the orchard of Thomas B. Wilson, Halls Cor- 

 ners, N. Y. A row containing 14 Baldwin trees was sprayed in 

 full bloom and the same number of trees in the next row which 

 were not sprayed in bloom were selected for comparison with 

 them. Five Rhode Island Greening trees were sprayed on one 

 side only while in bloom and one was sprayed on both sides. 

 The portions of the five trees which were not sprayed in bloom 

 were to be used for comparison with the sprayed portions. The 

 trees selected for the experiment have been planted 29 years. 

 They are quite uniform in size and generally are in good health 

 and productive condition. 



Treatinmt. — The first treatment was given to all of the trees
