' The cherries were picked from plots i and a on June 25. A rain followed on June 26, and the cherries 

 from plots 3 and 4 were picked on June 27. The rain probably resulted in there being relatively less pro- 

 tective material left on the dusted than on the sprayed fruit. The picked fruit from plots i and 2 was not 

 placed under ice till June 27. and this delay in cooling may have partly or entirely offset any harmful 

 effects from the rains received by plots 3 and 4 Two lo-pound boxes from each plot were shipped in a pony 

 refrigerator to Washington, D. C, were received warm July 2, were held overnight at a temperature of 

 approximately 7° C. (44.6° F.), andnotes were taken July 3. The sound fruit was saved, and half of the cher- 

 ries from each plot were stored at a constant temperature of s° C. (41° F.) and half at a constant tempera- 

 ture of is" C. (59° F.). On July 15 notes were taken on the amount of rot that had developed in storage.
