WINTER MEETINd.                   155
sprayed trees at Baraboo in 1909, fifty-four barrels were snund
and seven barrels unsound, making a percentage of unsound
fruit of 11 per cent. From 145 barrels of MeMahons harvested
from sprayed trees on the farm of Henry Dworak at Casco, Ke-
waunee County, 135 barrels were estimated sound and ten bar-
rels unsound, giving a percentage of unsound fruit of 7.2 per
cent. At Oshkosh in 1909, on the farm of R. T. Smith tL e
average precentage of unsound fruit on sprayed trees, all varie-
ties, was 6.5 per cent. The average percentage of unsound
fruit from unsprayed trees was 81.7 per cent.
The above figures represent only in part the data collected
but will give an idea of average conditions. The beginner ;n
orchard spraying must understand that orchard spraying means
making a business-like investment and giving close attention to
such details as 1, selection of desirable equipment and spray ma-
terials, and 2, timeing the applications in accordance with the
development of the pests in the orchard.
The following estimate of complete equipment is given using
200 bearing trees as a basis. The reader is asked to notice that
all material and equipment is purchased new, and that on the
average farm there is considerable chance to economize upon
the statement given. The average orchardist shows a tendency
to neglect the work by selecting equipment and material un-
suitable for the purpose and otherwise neglecting essential de-
tails.
