p. 10: The exDerimental results obtained in different 
sections of the country on the sour cherry with respect to its 
self-fertility do not entirely agree. The majority of evidence, 
however, indicates that most varieties will set commercial crops 
thru the use of their own pollen. Shoemaker ... has recently 
shown that the set of Montmorency is increased under Ohio con- 
ditions by the use of early Richmond pollen, but it is doubtful 
whether the increased set will compensate for the space occupied 
by the trees of the inferior pollinating variety. Interplanting 
of several varieties, better cultural practices, and the place- 
ment of bees in the sour cherry orchard is recommended for in- 
creasing the set of fruit .

p. 23: With fruit so dependent upon cross-pollination as are 
cherries, the agents responsible for this transfer of pollen need 
to be considered. The number and presence of wild insects can be 
controlled very little, but the honey-bee can be controlled to a 
great extent. It is becoming the practice for cherry growers 
either to keep their own bees or to hire stands of bees during the 
blooming season. One hive to one or two acres of cherries is 
sufficient if the stands of bees are strong. 
The sour cherry may be self-sterile, self-fertile, or partly 
self-fertile, depending on the variety.
