 by our records and experiments, and (6) a set was reported to have occurred — tL' 

 first for many years.

 Strawberries keptctmslantly wet by frecpuuit si)iinkling during the tiun-

 fewer berries than those left uucoveicd. The flowers on an .apple tree 

 kejit wet by spraying failed to set fruit, although surrounding trees ol 

 the same kind which were dry produced a full crop.
