Hog Cholera Experiments.
Among number of experiments
under way to learn more about hog
cholera, one is to learn what hold it
has upon sucking pigs. From expert.
ments thus far worked out 1t seems
that SO per cent of pigs from immune
mothers are immune to hog cholera by
exposure as long as they are sucking
the mother. When injected with hog
cholera virus, that is, putting the dis
ease into their blood, the per cent
showing immunity was not quite as
high as by exposure. There was also
some variation in different litters, as
certain litters showed much higher
immunity than others. It is worth
while knowing that little pigs can be
protected in this way, but must be
made immune as soon as they are
weaned.
Soil Tests Interesting.
The Experiment Station has shown
for years that the soils in many parts
Of the state are in need of lime. In
careful study of samples taken dur
ing the past year, in Prairie, Pope
and Washington counties, the upland
soils were nearly all found to be acid.
This condition can be corrected only
by the use of lime. The most econom-
teal form of lime to use is crushed
limestone, at the rate Of one or two
tons per acre. applied on land that is
| to be seeded to clover or alfalfa.
The bottom land soils along the larger
streams do not appear to be greatly
in need of lime at the present time.
The investigation is to be extended
to all parts of the state as soon as
funds are provided to continue the
work.
Experiment With Seventy Varieties
Of Potatoes.
! An experiment with seventy varie-
ties of potatoes has been under way
for several years. The 1915 season
was rather moist, and the past rath-
er dry one. The size, shape, eyes and
general appearance of the tubers have
been studied. Yields of marketable
potatoes and culls per acre, at differ.
ent dates during the season, have been
secured. These yields at different pc
RODS were secured to determine the
ACCESSIBILITY of digging at the regular
time for early market or Of waiting
| for further maturity. Market reports
have been kept to compare the prices
! at the different diggings.
| There are two striking things about
our results so far:
l. There are about twenty varie
ties outyielding the Bliss Triumph,
the most popular commercial variety
now being grown.
2. About three-fourths of the high
est yielders have been white potatoes
OF these varieties the best and most
consistent yielder has been the Irish
Cobbler.
The experiment was carried on al
Fayetteville and Van Buren, this year
and it is to be continued another year
at least.
SeH.Feeder for Hogs Proves Valuable
Experiments with the self-feeder fol
hogs have shown that the self-feedel
not only saves time and labor, but also
makes larger, cheaper gains at ar
early age, due to each animal balanc
ing and increasing it's daily ration &C
cording to it's individual requirements
The self-feeder is becoming very val
liable and useful in pork production
especially in this day and age, wher
with the present high priced feeds
and labor pork must be grown as
cheaply as possible. The self-feedel
is adapted for sucking pigs and fat
tening shoats. The cost of the feeder
is small; every farmer with small
herd could afford to build one.
Cotton Variety Tests Give lmportan,
Results.
Cotton variety tests were made b,
the Experiment Station in 1915 at fit
teen different points in the state. The
tests served many purposes, but two
things are of much importance.
