54° at different times of the day. The plot of eight rows was at the 
end of the orchard and consequently well removed from the check. 
yiay 2/, these trees were found unusually infested as compared 
with others treated at the time. Of 575 scales examined, 159 were 
living — a ratio of 28 per cent. At the fall inspection, September 5, 
the average infestation of this plot was rated at 3.43* giving a bene- 
fit of 19 per cent, for the treatment if compared with the check, or 
about 12 per cent, if compared with its own January condition. 
The principal data of the foregoing discussion may be conveni- 
ently summarized, for further consideration, in the first of the fol- 
lowing tables.
