inches high, tied tightly at the top
and allowed TO flare out at the bot
tom so that 4 few inches of dirt may
be put upon the edge of the paper.
The moth then lays the eggs upon
the paper and the larva starves.
THE wEBBERs.
The webbers are very large family.
They all live in webs at some period
Of their life's history, and all except
one live on grasses or vegetables. This
one is the bee moth that lives in bee
hives. The sugar beet web-wor1n is
one of the worst of this group. It's
eggs are laid on the under side of the
leaf of the beet in early spring. The
young larvae live in webs on the leaves
When full grown, they burrow and
make a tube in the ground, resembling
that of the trap-door spider, but small

ter in this kind OF burrow. This is a
most fortunate circumstance, because
IN the sugar beet fields, the ground
being highly cultivated, water and dis
ease enter and kill many of the insects
The Hour moth and the Indian meal
moth are likewise web worms. They

The best remedy is to clean up and
admit fresh air and sunlight TO the
-four bins and pantries.
THE TORTRIcIDs.
These are small moths. the larvae of
many of which fold roll or tie leaves
to form houses in which they live when
not feeding.
The strawberry leaf folders may be
found in every strawberry patch. They
may be controlled by moving the leaves
after the crop has been gathered and
then burning the dry leaves where they
lle Straw may be added to increase
the fire.
THE COOLING MOTH.
This is the worm that infests the
apple. The moths are dark gray with |
y brown spot on each wing. They
|tome out early In spring and after the
~ the leaves and young apples. Most
n the worms OF the first brood bore

ie Pn-the calyN end. The larvae lives
u the heart of the apple. When near
g tull grown, 1t cuts its way to the
surface and drops to the ground. II
flnds some sheltered place, as under
me apple tree bark, in which to spin
its cocoon from which week or ten
days later the moth issues. The second
brood burrow into the side of the APP
PIE, and vary their life by passing the
winter In the cocoon stage, the moth
emerging In the spring. These facts
indicate two means of combating the
pest First we should spray with
Paris green or some other arsenite
Immediately after the blossoms fall
from the tree. The calyx OF the young
apple is then pointing upward, and the
lttle cup formed by It's leaflets can be
nlled with the poison spray. The
worms entering here are killed by eat
ing this poison. The other means must
DC used in conjunction with spraying.

every week and destroying the worms
found therein, we prevent the second
brood from being numerous.
