to one orchard. Observations were made chiefly at Lincoln. 
Spores were found exuding on June 2. They were more abundant 
than in 1913 or 1914, and could be found in fairly large quantities 
for 20 days and in smaller quantities for several days longer.

The evidence shown in table 37 indicates that while some 
infection must have taken place earlier, the greater part of it 
occurred after the 35-days spray. Blotched apples were first 
found the last of June. This also indicates early infection. 
iNot sprayed in 1914. Received same treatment as plat 5 in 1915.
