CHAMPION
OPEN CENTER OR TRACTION CENTER
n
TThere are many tractor tires on the
market today but only two basic types — the
Open Center and the Traction Center. Some
farmers prefer the Open Center for their
soil conditions. Others prefer the Traction
Center. Only Firestone builds both.
If you want the finest Open Center Tire
that money can buy—or — if you'd rather
have the one and only Traction Center,
you'll find it in a Firestone Champion.
Both Champions have the curved bar
design to give you the extra leverage neces
sary for full trâctipn power. Both have
•Flared Tread Openings for positive cleaning
action. Both have many extra-traction and
long-wear features not to be found in
• other tires.
Make your next tires Firestone Cham
pions— either Open Center or Traction
Center.

They 9 re Doing ft
—HEALING BURNS with a new
dressing made from milk. After
three months of testing a prepara
tion made from milk is being hailed
by doctors as the most effective
burn" treatment of all. It involves
the mixing of hydrolyzed milk (the
same state as milk partly digested)
in a jelly base. The preparation is
then applied to gauze which has
been impregnated with zinc acetate
to make it firm. When applied to a
bum the preparation becomes pli
able and firm like white rubber,
keeps the fluids at the burned area
where they are needed and does not
admit bacteria-laden air.
—CHECKING HEREDITY trends
by using the fast multiplying fruit
fly. British scientists have selected
lines of fruit flies for 70 generations.
This is about equal to 110 years of
selection in poultry, 280 years with
sheep or dairy "cows. One line se
lected for long wings increased
steadily for 30 generations. The size
remained the same when selection
was stopped. Another line improved
for 20 generations, then stopped
even though selection was con
tinued. When selection was stopped
the size quickly went down. The
tests emphasized what breeders
have long known—breed improve
ment is a long, continuous process.
—PREVENTING SHIPPING FE
VER in cattle by injecting penicillin.
Some veterinarians are reported to
have had success in giving an injec
tion of long lasting penicillin to cattle
before loading them for shipment
to shows or sales. The penicillin will
last about five days and presumably
will protect the animal for that
length of time from germs that may
attack it while its resistance is low
ered by exposure.
—CURING BLOAT by injecting a
substance into the rumen. One the
ory about the cause of bloat is that
gas is trapped in the rumen by mil
lions of tiny bubbles such as cre
ated in a dishpan by a detergent
which decreases the surface tension
of water. The new drug acts in the
opposite way. It increases the sur
face tension of liquids in the rumen
and reduces the buildup of gasses.
