tended well into the fall. The temperature during the greater part 
of the season was slightly lower than normal. Because of these 
conditions the codling moth did not multiply as rapidly as during 
the two preceding seasons. The broods were more definitely 
defined, and the second brood was considerably later in appearing 
than in 1913 or 1914. 
The same general plan was followed as in 1913 and 1914. A 
strenuous effort was made to fill all the calyx cups thoroly, and it 
was planned to apply the third spray on different plats 7, 14, 21, 
and 35 days respectively after the falling of the petals.

At Beatrice (table 8), the same machinery was used as in 1914 
Bordeaux nozzles were used for the petal-fall spray on all but on 
plat, and a pressure of 225 to 250 pounds was maintained. Coars 
mist nozzles at a pressure of 250 pounds were used on one pla' 
The efficiency of the schedules was: No. 3, 93.3 per cent; No. a 
^Arsenate of lead was combined with Bordeaux.
