No pickings were made from the nonheated plat 3 in September or December. 
A study of figure 1 1 
shows that with one 
exception the curves 
of merchantable fruit 
in both the inade- 
quately heated and 
the efficiently heated 
plats are considerably 
higher than the curve 
of the same class of 
fruit in the nonheated 
orchard. The diagram 
also presents strikingly 
the differences in per- 
centages of merchant- 
able fruits in the par- 
tially heated and effi- 
ciently heated or- 
chards. With the 
exception of the pick- 
ing in December, the 
percentages* of mer- 
chantable fruit in the 
partially heated or- 
chard are found to be 
somewhat lower than 
the same class of fruit 
in the well-heated one.
