When and Why to Protect
Trees and Shrubs.

county Horticultural Inspector John
+ Sorenson has prepared a brief treat
Use on spraying which will be read
with profit by all fruit growers. Mr..
Sotehsen tells what the bugs are that
90 the damage and tells how TO de-
stroy them. Following is the bulletin
prepared by Mr. Sorenson:
Many books have been published and
bulletins written about Spraying but
the trouble is mostly that such bulle-
tlns and books only come in the hands
OF the few. Often on account of the
hlgh flown language or because they
elaborate too much or become dry or
long drawn out and full of scientific
ana technical terms, they are quietly
laid by for reading when we have more

several requests have been made for it.
insects are claSsed in several groups,
but for practical use we may consider
them in two classes: Those that eat
and those that suck The eating insect,
Ike the apple worm, the pear and cher
~ slug, the caterpillar, the measuring
worm the beetles, and other bugs and
worms that eat should always be
sprayed with an arsenite that is, a
Paris Green or London Purple solution
or arsenite of lead, or white arsenic
dissolved by boiling with washing soda
and afterward mixed with limewater
for large work the white arsenic is far
the cheapest, but rather more danger

after mixing any of these poisOns ac-
cording to formula that after having
put insects or worms into the barrel,
the poisoned water did not kill the
worms. Why, certainly not If you
threw a barrel of Paris Green on your
horse or COW, do you think II would
kill it? No, of course not. But try to
mix a pound of Paris Green with the
oats for your horse, or in the bran for
your COW, and you would soon be in the
market for another animal. These poi
sons do not operate before they get into
the animal or into the insect or bug.
They do not operate on the outside, but
only when eaten by insect or animal
The other group of insects are the diff
ferent scales, the red spider the plant
lice, the aphis- green black and woollY
aphis, all of them sucking insects that
