is go slight as not to be a serious factor in fruit production. The 
opinion is commonly held that even the varieties considered to be 
self-f in a h igh degree wi ll set a better crop of fruit if 
■lination occurs . With self-sterility prevailing to so large 
extent in common fruit varieties, the r elation of weather conditions

Wh e n se l f-ste rile varieties are planted and there are no other 
tre es of diffe rent varieti es of the same kind growing near enough to 
insure the p a ssing of b ees from one to the o ther, it will be found 
that tre es blossom but d o not set._fruit . 
When the tree to be cross-pollinated is in bloom secure some 
blossoming branches from a tree of another variety of the same kind of 
fruit and place them in a pail or other water container in the top of 
the tree. Th e b e es, v isitin g the tr ees, wil l also visit the blossoms 
on the br anches and will thereby transfer the pollen as they revisit 
the blossoms on the tree .

p. 1: With proper care bees winter over in large numbers and 
are very active in the spring. They are especially well adapted to 
carry pollen. Their bodies and legs are covered with hairs to which 
the pollen grains adhere in large numbers. Moreov er, the hone ybee 
vis its o nly one kind of flow e r, like the apple or the peach, at a 
time . Thus they are very effective agents in cross-pollination . 
P • 9 : It has been demo nstrated in many orchard s in a convinc- 
ing way that bees _ g r^at vai-p for the pollination of apples, 
sour cherries, an d o ther fruits. If the orchardist does not keep his 
own bees and there are none in the neighborhood, then most certainly 
it will pay to secure several hives.

p. 4: The fruit grower has a pollination problem with almonds , 
che rries, plums and prunes , apple s, pears, and berries . In' general, 
apricots , peaches , and walnuts set well with their own pollen and 
hence present no difficulties from this standpoint. The J. H. Kale 
peach, however, is self-unfruitful and must be interplanted with 
some other variety. Recent studies indicate that some varieties of 
walnuts in certain years do not mature the staminate and pistillate 
flowers at the same time and therefore, under these conditions, cannot 
pollinate themselves.
