suffice. The first two sprayings this year were made on the same dates 
as last—May 15th and 21st. — and the third a day earlier, — 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 4th, 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 thoroughly. 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, ete. 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.
