few are abandoning their dusting ap¬ 
paratus because the area of the dust 
can not be controlled. Sometimes 
dusting is wholly ineffective because 
dust does not lodge where it will do 
good. Dr. H. A. Surface, State Zoolo¬ 
gist of Pennsylvania, has stated that 
dusting is not as efficient as spraying. 
The difficulty is that the dust is 
carried everywhere by the wind and 
unless the foliaga is wet with dew or 
rain it is blown into the air. The dust 
may fall on the cover crop; and when 
it consists of any of the clovers it may 
fall on blossoms that are just in the 
height of the nectar secretion and upon 
dandelion blossoms in or near the or¬ 
chard. Bees gather this poisoned nec¬ 
tar and die by the thousands. The dust 
may be carried hundreds of yards in 
all directions. Even though the bees 
may not be working on the clover 
blossoms they may take up the morn¬ 
ing dew from the grasses and plants 
that have been dusted previously with 
arsenical mixtures. When the spray is 
used the effect is strictly local, and on¬ 
ly on the trees that are out of bloom. 
As a rule it is much safer to move 
bees from the orchard entirely when 
arsenical poisons are applied either in 
the form of a liquid or dust. If the 
orchardist will take the proper precau¬ 
tion to apply the dust when there is 
little or no wind, in the early morning 
when the dew is abundant, and if he 
will wait until the petals of the flow¬ 
ers have fallen and no other nectar¬ 
bearing flowers are in or near the or¬ 
chard, no bees will be killed. Dusting 
machines are not here condemned 
when used at proper times. 
It should be stated that neither
