294 Report OF THE DEPARTMENT OF IEXNTOMOLOGY OF THE 
days the weather was cloudy with a high wind and occasional 
flurries of snow. The temperature varied from 31° to 36°. The 
mixture was boiled in barrels with live steam. McGowan and 
Seneca nozzles were used. As in the other orchards the trees 
were sprayed very thoroughly once and retouched twice. None 
of them were trimmed after the spraying was done. Owing to 
the very heavy winds much of the material was wasted, making 
the amount used per tree average nearly 214 gallons. 
The weather conditions during the thirty days immediately 
following the treatment were the same as given for Orchard II. 
Effect on the trees.— In general the results in this orchard were 
the same as in the preceding. There was no apparent effect 
upon the trees except to delay the opening of the buds from 
three to six or seven days. The final examination made July 30 
showed that the trees had made a better growth than for a 
number of years. There was no evidence of injury to bark, 
leaves or fruit. Where the wash had been the bark was usually 
clean and smooth. The foliage was better colored and more 
abundant, especially on the trees that had been most seriously 
infested, than for a number of years. It was much better than 
that of the infested checks. The fruit, especially, showed the 
effect of the treatment. It was as a rule clean, only an 
occasional one showing the marks of the scale. The crop of 
marketable fruit was largely in excess of any previous year in 
the history of the orchard. 
Effect on the scale-—— The frequent examinations made in this 
orchard during the summer showed the same general effect as 
previously reported. There were enough encrusted trees to give 
abundant data on the effects of the treatment on the scale. In 
this orchard as on Long Island it was apparent that the wash 
had had a secondary effect upon the young larve. Very few 
live scales could be found, but all that were found were upon 
the new growth. Only three fruits in the entire orchard were 
found with scales upon them. The fruit of some of the trees 
had been in previous years so badly infested as to be unsalable. 
liffect of the weather upon the wash.— In this orchard the 
wash seemed to weather off somewhat more rapidly than in
