Occasionally a farmer notices that neld

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 slow and un-
slightly death through insect infestat1on. Have
you never late in May or 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 kerosene emul-
sion was effective in disposing u these pests
A 20 per cent emulsion could be used In winter
if the roots of the trees were protected and
10 per cent in summer 1t is made by dissolv
ing one pound of common soap In one gallon
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
hack into itself for about five minutes, when it
will look like thick cream, and no longer sepa-
rates on standing. Seventeen gallons of water
added to the three gallons thus prepared will
give a 10 per cent. solution. The cost will
be 43 cents gallon and three or four gallons
will save large tree from destruction.
Doubtless you have noticed uNon the apples
yon brought home in a paper bag and those
TINT fell from your own cherished tree cres
cent mark This means that busy little curculio
has had it's beak In your apple before you and
has probably laid an egg at the sign OF the
crescent curculios A spray compound OF 12h
ounces of acetate of lead and four ounces OF
arsenate of soda to fifty gallons of water. If
used three or four times, will eaten practically
all these orchard destroyers.
Among the insects injurious tc health the
common housefy takes first rank. DR.. Forbes
has found that Is per cent. of thu common
housefies breed in horse manure AS the RENE
dies that will kill the housefy maggots are too
dangerous to be used in stables, except boiling
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.
