this newly sprayed cow. They all
fall dead and are replaced by another
1,000 that likewise fall dead. And
suppose there are 60 cows in the pas
ture. That knocks off 120,000 flies
in the first hour. If we keep this up
for two or three days we soon run
out of flies. Whether these figures
are fight or not, that's just what
happens; we run out of flies. And
from any viewpoint, that's a good
idea.
After about three weeks the DDT
loses its wallop, and the flies become
troublesome again. A second spray
ing lasts a little longer, about a
month, and carries the cattle through
the worst of the fly season. And the
cattle have been comfortable, no run
ning, no shading up at noon, no tail
switching, just undisturbed grazing.
A herd of beef cattle in Oklahoma,
where they really have flies, was
divided into two equal groups, one
sprayed and the other not sprayed,
and grazed on separate pastures. The
sprayed cows put on 40 pounds more
beef in the summer grazing period
than the unsprayed cattle did. A
dime's worth of spray made $15
worth of beef.
Nothing Complicated
There is nothing complicated about
this fly-control, it doesn't even re
quire brains. Just get some DDT,
some sort of a spray-gun and follow
the directions on the DDT package.
Most people prefer to spray cattle in
a chute, but they can be sprayed
quite well in a corral if it is not too
large. High pressure sprays are not
required, 50 to 60 pounds is enough.
All we need is a heavy "mist" spray
that will wet the hair.
If the spraying is followed by a
couple of days of blazing hot sun
shine, that makes it tough, for sun
shine breaks down the DDT. But
of course, we have to take our
chances on the weather. If the
weather is hot and bright, we may
have to spray again in two weeks,
otherwise one spraying should hold
the flies for three weeks or longer,
DDT is not a fly repellent. It does
not keep away flies, it kills them
after they light on the cow. And it
doesn't kill them at once. My office
in the veterinary building is sprayed
about once a year with DDT. Every
now and then some outside fly comes
zooming in and messes around a
while and then lights on the wall to
rest. That's all for him. In about
10 minutes, he goes into a tailspin
and dies. A sprayed cow is really a
fly-trap, and with enough cows, the
fly supply soon runs out.
Spray Hone« Too
I believe in this fly spraying. And
if I owned a bunch of horses, I would
spray them too. It makes me half
sore to see a bunch of horses fighting
flies in a hot, treeless pasture, when
$1 worth of DDT would keep them
comfortable all summer.
There is one drawback—the big
green headed horse fly doesn't seem,
to be bothered by DDT and cattle
pastured near the timber will have to
fight these big flies. But the horse
flies are temperamental, and will not
fly on rainy or cloudy days and are
not as troublesome as the swarms
of stable flies and horn flies.
As we said to start with, there
isn't any schedule that has to be
followed. We can spray the cattle
when we please, in any way we
please and spray them again when
the flies seem to be bothering them
again. People who have sprayed for
flies almost all stay with it. It seems
a shame to let a bunch of cattle be
bothered all summer by these pests
when so little expense and labor can
prevent it.

Got a favor to ask of some of
you folks this month. First, let me
give you some of the background.
Pinkeye, we know, results in ani
mal shrinkage. The shrinkage gets
worse as the disease progresses.
Gettin ' right down to pounds,
dollars and cents that are lost
because of pinkeye is what Pm '
aimin' to find out. But I need
your help. £rZ * Of ^ „3//

Dan uses new formula K-R-S* with diphenyla
mine for maggot elimination because :
1. K-R-S kills maggots on contact.
2. K-R-S keeps wound toxic or poisonous to
newly-hatched screw worm larvae.
3. K-R-S is non-irritating to tissues.
4k K-R-S offers antiseptic qualities to pro
mote healing.
K-R-S—Imprevod —available in handy

average. Costs depend, too, on
your range conditions and the
supplemental feeding formula
you're followin'. What I want to
get is more definite dope on the
rate of loss if pinkeye hits some
of your cows — and I hope it
Feeder people who have a little
more control over animals will be
able to figure losses easier than
you folks who are rangin' your
critters, but give it a try, will
you, please, for Ol' Bull?
'Course you know 'cause I've
told you so often that when pink
W starts liftin' dough from your
jeans, you can stop it with Cutter
Trisulfano!.*Usually just two ap
plications from our handy sprayer
bottle are all that's needed. Tri
sulfanol quickly and completely
bathes the infected eye tissue and
there's little or no irritation to
the mucous membrane.
A Trisulfanol plus value is
that it's good for healing cuts
and gashes. Used it on a wire
cut my pet saddle horse got the
other day , and the cut healed
up as nice as anything. No in -
lection at all.
If you can get the loss of weight
on your pinkeye animals, send it
