The efficiency of schedules Nos. 1, 2 and 4 (table 19) was 
approximately 100 per cent and that of schedule No. 3, 37 per cent. 
The curculio infestation in all of the orchards under observa- 
tion was so light that no reliable conclusion can be drawn. How-

tables 16 and 19 must be more than a coincidence. 
EXPERIMENTS IN 1915 
In 1915, the work was continued as in the preceding years, but 
in the data the larvse and skin punctures were recorded separately.
