scale need not be destroyed, according
to the latest bulletin from the Ohio
experimental station. Indeed, digging
up and burning is rather discouraged,
for the reason that il other trees are
planted in the same soil they soon be-
come infested. The advice is to prune
closely and then spray and treat as
directed.
Anything relative to this pest Is Of
vital interest to the people of Canton
and Stark county, as thousands of trees
are threatened with destruction by the
scale. The latest bulletin issued by
the Ohio experiment station is as fol-
lows:
Various mixtures have been pro-
posed for this insect and a number
have been found to be more or less
effective. 1t is hardly possible, how
ever, to apply any remedy with such
thoroughness as to reach every scale,
and because it's natural enemies arc
few and its rate of reproduction very
rapid, complete eradication is practi-
cally impossible, but by treatment
each season it is entirely practicable
to hold it in check.
NEW SOLUTION.
Good results have been secured in
spraying scale infested trees with %
per cent of crude petroleum and water,
also with higher percentages OF oil.
Trees have been injured, and even
killed. with 25 per cent of oil. On the
other hand, many thousands of trees.
in all parts of the country, have been
sprayed with clear crude petroleum,
and with various percentages, without
injury.
The manner of spraying has much
to do with the effect upon the trees.
When the material is applied in such
quantities as to run down the limbs
and bodies of the trees injury is al
most sure to occur even If the oil is
diluted with water. Sometimes the
operator, trusting to dilution to pre-
vent damage. sprays excessively, or
roots. The oil is thus unevenly dis
tributed and unknown quantities reach
certain parts of the tree, resulting in
local injury.
Peach trees are very tender and
should be sprayed with more than or
dinary care. If whale oil soap is used
the work should be done just as the
buds are swelling.
The only safe way is to stop spray
ing before the material begins to run
and this rule applies to diluted as well
as to clear crude petroleum. A nozzle
which will give fine spray is needed
in all cases, and for this purpose the
Vermorel Is satisfactory. Choose q
day for spraying with crude petroleum
when evaporation is rapid, as greater
injury is done in damp than in drying
weather.
WORK DOWNWARD.

blowing all the better. A light wine

as may result by spraying up and dowr
the tree. If the wind is brisk hold thu
nozzle high and let the material drift
through the trees. In this way tree
some distance away may be covered
almost as we'll as those near by. Th'
operator must shift his position ant
change the height of the nozzle as ex
perience shows to be necessary. Whel
the wind changes another application
must be made on the other side of tn
trees. There is less danger of over
spraying in a high wind than whel
the air Is calm, but there Is also
greater probability of missing parts o
trees. In early spring, just before tn
buds open is the best time to spray
although no harm may be done if tn
work is performed earlier. The worl
can be done much better II the tree
are first severely pruned by cutting OF
the ends of the branches. In case tree
are seriously infested this operation
necessary in order to secure good re
suits, after removing one-third or one
: half of the top. Peach trees will en-
dure very close pruning and no harr
will be done il the top is all cut ava
