natural tendency of all vine crops, a large number of male blossoms 
appear in advance of the vines to set fruit. At the base of the 
pistillate or female blossom is located the small embryonic melon 
formed before the blossom opened, and it is necessary that the pollen 
from the male flower be transferred by bees or other insects to the 
female flower* Where melons are grown in greenhouses or in closed 
frames it is essential that provision be made for the entrance of 
bees in order that the pollen be transferred .

p. 675? The nectarine was formerly thought to be a different 
species from the peach. It is now known that the nectarine is simply 
a smooth-skin peach. The trees differ in no respect from the peach, 
and it is impossible to tell a peach tree from a nectarine tree. 
p. 695: Most varieties of peaches are self-fruitful. Occasion- 
ally failure to produce crops may be due to pollen sterility, which 
is exhibited in a few commercial varieties, such as J. H. Hale, 
Halberta, Candoka, Mikado, and Chinese Cling.

p. 29: A J. H. Hale peach orchard favorably located on the 
Friday Bros. Farm near Coloma and containing a few scattering trees 
of other varieties had produced but a few fruits since planting in 
1917. When it was learned that this variety was self -sterile, South 
Haven and Elberta trees were planted in the vacancies as pollinizers 
for the J. H. Hale. In spite of this provision the orchard produced 
less than 10 bushels of peaches in 1926. Before the succeeding blos- 
soming period. 20 colonies of bees were located in the orchard and it 
produced the first crop of fruit in 11 years .

p. 24 t that cross-pollination is advantageous to setting fruit 
of practically all varieties is now generally conceded. Provisions 
for cross-pollination should be made, notwithstanding the fact that 
such varieties as Bartlett, Anjou, and others may, under favorable
