POINTERS BY THE INSPECTOR.

Insurance Against Mildew-The
Pink Spray--It will shortly be time
for the pink spray, the first step in the
presentation Of loss from mildew in
jury. If we could forecast weather
conditions exactly, We could tell how
bad year this would be for mildew
and even estimate the probable loss in
dollars and cents, should the pink
spray and those that follow be neg
lected Since We cannot do this, the
|only safe plan is to insure against loss
by starting to spray in the pink. II it
should be clear and dry after the bios
|soming period. we might find that the
spraying in the pink was unnecessary,
but this would be no more cause for
regret than II a mans house failed to
burn down after he had insured 1t
against fire. II, as seems probable,
the year should be bad one for mil
dew, 1t is very important to nave. first
Of all, good pink spray, partly be-
cause it aids greatly in control Of the
disease and also because it greatly
lessons the danger of sulphur shock"
to the trees, which might result in the
dropping of fruit. Use lime sulphur
TO so, with spreader.
Protecting Young Trees from Bor-
ers-With the great amount Of plant
ing that has been done Of late, tle
question of possible damage from bor-
arc 10 Of in 10
let the tree and the borer fight it out,
should eggs of the latter be laid on
the tree. II the tree is thrifty one,
well planted, and we'll taken care Of,
the tree will doubtless get the best Of
the argument, drowning out the borer
can cut off the flow Of sap to the tree.
II for any reason the tree should fail
to get well and quickly established,
the borer might win the struggle. -
1t is also possible to prevent the
eggs from being laid on the tree, and
. be no injury. Cones made from pages
of magazines (as described by Roy
Larsen in late issue Of the We
natchee World) may be placed to keep
the egg laying beetle from the lower
part Of the tree, the danger zone.
These should be pinned to fit snuggly
around the tree at the upper end and
should flare out at the ground line
After being placed in position an inch
or so Of earth should be piled about
the bottom Of the paper cone. II this
method Of protection is to be used the
cones should be in position by May

Cooling Moth Observations-Ir
neighboring districts, this is the year
of the war on codling moth. Ey far the
greater number of the worms which
were so plentiful last year, lived over
the winter in good health. and are now
getting ready for further mischief
We are particularly favored in this
district in having what is relatively 6
small crop of worms, but we can be
very sure that only the utmost vigil
ance can keep us comparatively Stree
from them. The districts which suffer
ed so severely last year were them
selves comparatively clean, not 81
long ago.
The most important thing, OF cours,
is to be sure that an ideally thorough
calyx spray is given by everyone whit
Towns an apple tree.
The next thing Is to be sure that tn,
cover spray is properly timed. Ever.
grower should equip himself with a
least one good thermometer, and rea'
it about dusk each night after tn
calyx spray. AS Mr.. Newcomer pointe,
lout a succession Of two or more night
with temperatures of so degrees o
higher will give the time at which eg
laying starts. and in the days afte
this the eggs will have Matched an
the young worms will be starting t
bore into the apples. These dates ca
be so readily determined by eac
grower for his own special location
that no grower should be without tn
Information.
To give further information on tn
rate Of appearance of the moths, cage
will be established around infeste
trees. According to present plan
J there will be one of these at Orovill
7 and one near Ellisforde.
