suffice. The first two sprayings this )-ear were made on the same dates 

 as last — May 15th and 21st. — and the third a day carher, — May 25th. 

 A more dilute solution was used this season however, London purple 

 being applied in the proportion of one pound to 160 gallons of water as 

 against one pound to 100 gallons last year. 



The cherries had begun to turn red June 4lh, and the examination 

 for curculio injuries began on that date, continuing until June 12th. 

 One thousand cherries were picked from each of twenty-four trees in 

 each half of the orchard, care being taken to select limbs in all parts of 

 the tree and strip them thoroughl}\ Each tree was labeled with a letter, 

 those on the sprayed portion being tagged as A, B, C. etc., and those 

 on the unsprayed portion which corresponded in situation with those 

 named being labeled A check, B check, C check, etc. As just stated, 

 the checks were selected according to their situation, principally because 

 this was the only practical way of doing it ; and though occasionally a 

 tree and its check would hardly be fair comparison trees because of the 

 difference in the amount of fruit borne by them, the total results could 

 not fail to be correct. 



The results obtained, so far as they relate to the injuries of the cur- 

 culio, are shown in the following table, the columns 1000 being the 

 number of cherries examined, and those to the right the number in each 

 1000 injured by the insect
