of the growing season, Sep. 7, 1900, was as follows. There were 
very few or no young insects on trees 60, 61, 79, 101 and 102, 
very few on tree 80, few on trees 16, 17 and 62; they were rather 
abundant on trees 34, 35, and numerous on tree 15. 
May 22, very few limbs were winterkilled on trees 34, 55 and 
80, and there were a number of dead limbs on tree 101. 
July 6, there were very few or no young scale insects on trees. 
34, 34a, 62, 80, 101 and 102, very few on trees 17, 35, and 79, few 
on trees 16 and 60; they were rather abundant on tree 15, and 
abundant on tree 61. The bark of tree 61 was very rough, and 
the sprouts on tree 101 were rather thrifty. 
Aug. 9, there were few or no young on trees 17, 34, 34a, 35, 60,. 
62, 79, 80, 101 and 102; they were rather abundant on trees 15, 
16 and 61. | | 
Sep. 25, there were few or no living scale insects on trees 34, 
62 and 101, very few on trees 15, 16, 17 and 102, few on trees. 
34a, 35, 60, 79 and 80; they were rather abundant on tree 61. 
The general condition of this lot of trees Sep. 25, 1901, is very 
fair. Living insects were found on three quarters of the total 
number, but not in considerable numbers, except in the case of 
tree 61, which was very badly infested in the spring of 1900, and 
ies! rough bark undoubtedly accounts to a large extent for the 
poor success in controlling the pest in this instance. The very 
few on trees 15, 16, 17 and 102 might easily have been carried 
to them by natural agents, since they are on the edge of the 
orchard near adjacent, untreated trees. In the case of the 
remaining infested trees, nos. 35, 60, 79 and 80, while they may | 
have been reinfested, it is very probable that in each instance 
a few insects escaped the spray.
