The first warm sunny spring day make
a point of examining the ornamental and
, fruit trees, as well as the shrubs and
berry bushes. Perhaps on one of the
; APPLE trees will be noticed tiny round
dark brown spot about one-sixteenth OF
an inch in diameter, with darker spot
in the center. Look carefully, for it re-
quires very sharp eye to see this most
! insidious and destructive of all the insect
pests, namely, the San Jose scale. 1t
multiplies with marvellous rapidiyit, and,
not content with destroying fruit trees,
it also attacks ornamental trees and
shrubs. The San Jose scale is sucking
insect, and, like all sucking insects. it
must be destroyed by smothering. Lime
and sulphur solution or scalecde will do
the work effectively and will also destroy
oyster shell scale and scurfy bark louise.
When To Spray.
| The time to spray trees and shrubs for
scale is between October and spring be-
fore the leaves start. On another tree
perhaps, might be found the oyster shell
bark louse it is about the color of the
bark on which it grows, and is very in
furious where it occurs in large numbers;
| it looks little like an oyster and like
other scale insects, it readily succumbs
to lime and sulphur solution or scale.
eide.
Among the early insects to arrive are
the coddling moths, which are the com
mon cause of wormy apples. The female
deposits her eggs in the calyx 1.-THE top OF
the eye) of the apple just as the bios
SONS fall. On Matching, The worm eats
into the apple, where it lives happily I'M
til ready to change to the moth. The
remedy for this is preventive one:
spray just after the blossoms fall, never
before, with arsenate of lead, which
comes in the form of paste, obtainable
from any scotsman. The proportion is
one ounce of arsenate of lead to one gal
Ion of water. Ii the trees are to be
sprayed as a preventive against scab |
canker, and leaf spot diseases with Bor-
deaux, then it saves much time if both
operations are done together by using !
Bordeaux -arsenate o. lead mixture in the |
proportion of three ounces to one gallon
OF water.
The canker worm is small measuring
worm which defoliates the trees in MAY
and June. The time to destroy il is be-
fore the blossoms open, when it is just
Matching, by spraying with two pounds of
arsenate OF lead in 50 gallons of water;
repeat later If the worm is seen again.
Case bearers and budmoths must also be
looked for on young leaves and buds;
the former, a small caterpillar, lives in
a little pistol or cigar shaped case, while
the latter is brown caterpillar, but
the Bordeaux and arsenate mixture will
soon do away with them.
The tent caterpillar appears every
year, and the only sure means of de-
stroying this destructive pest is to watch
for the first sign of it, then pick the
small nests Off al night and either burn
them or dip them in kerosene. Under no
should the nests be- burned
on the trees, as the burning Injuries the
trees. Ii is quite possible to destroy
many of these caterpillars while still in
the form OF eggs, which may be seen in
circular clusters surrounding the small
twigs The fall.web worm appears in the
summer and autumn. and as il also lives
IN a tent is often mistaken for the tent
caterpillar; il should be- destroyed how.

In addition Ia this by no means com
