A similar test conducted in 1922 in a bearing Stayman Winesap 
orchard in Maryland where bees were placed in the orchard, together 
with blossoming branches of the York Imperial variety in- pails of water, 
resulted in a fa ir crop o f frui t be i ng set , even t houg h th e s eason. w:is

so ms, v ery little fruit "set" altho ugh th ere were ple nty of Stayman 
blossoms and the weather was favorabl e. 
In 1923 with good pollination weather and Grimes blossoms placed 
about the bee hives, a good set of fruit was obtained in this orchard. 
In some special tests at the Experiment Station in 1923, two 
trees, one a Grimes and one a Stayman Winesap, 40 feet apart, were 
inclosed in a large muslin frame 14 feet wide, 14 feet high, and 55 
feet long. 
A muslin partition was built through the center of the tent 
(long ways) so that one-half of each tree was on one side of the 
partition and one-half of each tree was on the other side. Bees were 
placed in one side of the tent, so that they could fly back and forth 
between the halves of the Grimes and Stayman Winesap trees. No bees 
were placed in the other side of the tent. In the side in which bees 
e placed, fruit set on the halves of both . the Stayman Winesap and 
Grimes trees. In the othe r s ide of the te nt wit h out bees, no fruit 
set on the ha lve s of. the same Stayman Winesap tre e, alth oug h the

in the one-half of the tent, the_Grimes polle n was carried b y the, bees 
to th e Stayman Wi n esap, givi ng a set, while in the other half, the 
Grimes pollen did not reach the Stayman blossoms. 
Another test of the value of bees was indicated in some experi- 
ments carried on at the College in 1923. Two hundred and fifty blossoms 
each of Baldwin, Lawver, Stayman Winesap and Kinnaird were emasculated 
and left unbagged or open to cross-pollination. Apparently, because 
all of the petals had been removed by emasculation, the bees were not 
attracted to these blossoms. As a result, not a blossom on any of 
the emasculated blooms "set." Other unemasculated blossoms (with 
their petals expanded) on the same limbs were apparently visited by the 
bees so that cross-pollination took place. In these cases 21.4 per 
cent of the Lawver blossoms, 6.4 per cent of the Kinnaird, 15.8 per 
cent of the Baldwin, and 5.3 per. cent of the Stayman Winesap "set" 
fruit. 
Fr om the above exper ime nts , it can be se en how important it is

orchards . The last experiment_also suggests that a great many 1
