Under these conditions it was more convenient to keep a 

 record of the trees and the notes on the same by number instead 

 of by charts, the trees being numbered consecutively in each 

 orchard, without reference to the kind of tree. 



All trees under test, of whatever kind, were treated while the 

 fumigators were near them, without returning to the same sec- 

 tion of the orchard at different times. The orchard was treated 

 in sections during the winter of 1900-1901, so that some trees of 

 each kind could be fumigated with different amounts of KCN at 

 different periods — while dormant and when the buds were 

 opening. 



Dates given in the tables should not be taken as proper time 

 for treatment except in sections of the country which have 

 relatively the same temperature.
