be rolled up like a carpet. BY preference they
devastate grass but if the supply Is scaht they
are willing to ruin small grain, corn, strawberry
plantations, woodlands and, indeed, many other
situations. They are especially difficult to COM
bat because the life history is hard to follow
from the first to the last stage. Only single
specimen has been bred from the egg to the
beetle and its life cycle occupied three years.
So far the best remedy has been found to
be in cropping, especially In planting the IN
tested ground to clover. Welknown enemies
of the white grub also are the festive porker
which will dig a foot for nice fat one, and
crows and crow blackbrds
Occasionally a farmer notices that a field
which has been brown from a grub ravage be-
comes green and alive. He is inclined to think
it clear case of the Lord remembering the
righteous; as a matter of fact another insect
has appeared and is working out another set
of instincts. This is the Tiphia a member Of
the solitary wasp family. 1t stngs the grub
into submission and then CLUES to its thick hide
an egg which in few days matches into a
veritable vampire 1t sucks from its host its
life juices, leaving the she'll TO crumble back
to earth.
Trees both those in natural forests and
those which have been planted, noble and
helpless products of nature" TO quote Dr.
Forbes, are often dragged to a slow and I'M
slightly death through insect infestation. Have
you never late in May in June noticed upon
shade trees little wads of cotton? Each wad
you will see, If you look projects from brown
cap, which is the female maple scale. 1t is a
native insect parasite of the soft maple 1t will
infest besides the maple, the linden, box elder,
elm and honey locust. These cotton wads are
the soft bed in which the careful female lays
her eggs, and each female can be relied upon
to deposit something like 5000 eggs in her own
particular little wad. DR.. Forbes found after
considerable experiment that a kerosene emul-
sion was effective in dispOsing of these pests.
A 90 per cent emulsion could be used in winter
if the roots of the trees were protected and
10 per cent. in summer. It is made by dssolv-
ing one pound of common soap in one gal<on
of water by boiling. This is removed from the
fire and two gallons of kerosene poured in.
With a spray pump the mixture is then forced
back into itself for about five minutes when it
will look like thick cream and no longer sepa-
rates standing. Seventeen gallons of water
added to the three gallons thus prepared will
give 10 per cent. solution. The cost will
be 43 cents a gallon and three or four gallons
will save large tree from destruction.
Doubtless you have noticed upon the apples
you brought home in a paper bag and those
that fell from your own cherished tree cres-
cent mark. This means that busy little curculio
has had its beak in your apple before you and
has probably laid egg at the sign of the
crescent curculios A spray compound of 12b
ounces of acetate of lead and four ounces Of
arsenate of soda to fifty gallons of water, if
used three four times, will catch practically
all these orchard destroyers.
Among the insects injurious to health the
common househy takes first rank Dr. Forbes
has found that rs per cent of the common
housefies breed in horse manure. As the rene
dies that will kill the housefy maggots are FOO
dangerous to be used in stables hniIi-,O
water which IS hardly practicable the only
protection seems to be in screening stables
against flies as we do our houses and in careful
city sanitation.
