Passing on a class of animals re-
quires a great amount Of mental
| concentration on the part of the
Judge, and If interrupted by an ex-
hibitor or in any other way, his
task is made more difficult. Every
exhibitor cannot win first prize, ana
their defeat with grace and ease.
Protesting judges decision usual
ly reacts with discredit to the one
entering the protest and is other
wise disagreeable. The best policy
is to play the part of a good loser
and profit by learning the, points
wherein your pig was excelled and
come back next year with a better
pig and with a determination to
make a better showing.
AN ECONOMICAL TYPE OF sILo
G. C. F., Douglasville, Ga,
writes: 1 am thinking of build
ing silo, and would like your
advice as to the best and most
economical type to build.
Many types of silo may be sue
cessfuily built in Georgia. Where
one wishes to make only small in
vestment and put up a temporary
structure a rough board stave silo
may be built. In such STRUCTURE
est possible form of a silo which
can be built, but as it will last only
for little while we advise against
| following this method of construc-
ton except in extreme cases.
Another type of silo which you
might build is that known as the
hoop silo. In this case the slaves
are beveled and grooved. They are
put together with. splines and iron
hoops are used to hold the, slaves in
place.
A third type of structure is the
lath and plastered silo. In its con-
struction iron piping is used for re
framework and high rib is attached
| thereto and then a heavy coating of
sharp cement plaster is put on the
inside and the outside. This makes
a very pretty structure and one that
is quite durable and satisfactory if
it is properly built.
On the other hand, the most per-
manent and desirable type Of silo to
construct is that known as the Mo-
nolithic silo. Where this method of
building is followed the silo is con-
structed of sand, crushed rock or
sharp gravel and cement Forms are
on the market which may be pur-
chased and used in its construction.
These are filled each day and raised
as soon as the cement has set suf-
to give a perfect exterior contour to
the silo and bevel the walls from the
base to the top. In other words, the
foot1ngs might be Is inches and the
width, Of the wall at the top not
over 4 inches. When silo Of this
practically forever and In the long
run it is by far the cheapest type
of silo to put up.
We have experimental with all the
styles described, along with several
other types not so generally used
and our conclusion is that wherever
the capital can be found and where
one expects to use silage as a
permanent adjunct in the mainte.
silo is the best and most satisfactory
| type to construct.
Protecting cowpeas Against weevil
Invasion
P. G. A. Putney, Ga, writes:
would like to know what to use
to keep weevil out of cowpeas.
The best method Of keeping weevils
out of cowpeas is to treat them
with carbon bisulphide. This may be
accomplished in one of several WAYS
but the best and simplest method
IS to store the peas to be treated in
large, rat-proof. tight granary. or
else to put them in good-sized boxes
or barrels and treat each individual
box.l To this end, carbon bisulphide
should be bought in such quantity as
may be needed and shallow pans
placed over the mass of peas into
which the liquid in question may be
poured In case of treating indi-
V1dual containers smaller pans will
answer. 1t is desirable to have a
tarpaulln or some cover to put over
| the container which is to be treated.
Carbon bisulphide evaporates i'm
med1ately when it comes in contact
with the air, and begin heavier than
, air, sinks down into the peas and eff
fectively, destroys the weevils. The
amount to use varies with the tight
ness Of the container. One and a
half pounds per ton of grain will
answer quite we'll for most condi-
lions. 1t is often necessary, how
ever, to use as much as two pounds
lively tight.
Carbon bisulphide is a white liquid
very offensive in odor, but will not
| BURN the hands or injure the cloth
ing. When the peas are exposed to
the air the odor passes off very
mating qualities are not affected in
any way. AS there are likely to be
| eggs In the peas it is necessary to
| treat the grain more than once dur
| ing the season so it will not be re-
infested.
How to Start With Alfalfa
| S.. J.. B., Barlow, Ga. writes:
1
alfalfa, but as it is not grown in
| this vicinity, I would like some
particulars regarding inocu1a-
ton, time of paintings prepara-
ton of soil, etc.
Where one wishes to plant the
land to alfalfa it is necessary to pre-
pare very thorough seed bed. In
your section of the state you could
delay planting until as late as No
vember, but We do not think this ad-
| vlsable, as our experience leads us
to believe that earlier planting is
good practice. 1t would be well to
plant alfalfa in your section around
! October Is, provided seasonal condi-
| tons are favorable. In the case of
a dry fall, and very dry land on that
account, it would be better to delay
planting until there is more moisture
ton. Nothing is to be gained of
course, in planting alfalfa in a dry
season. One, therefore, has to change
the date Of planting two or four
weeks from the most desirable time
of seeding on account of seasonal
conditions. Early planting, however,
is to be preferred whenever this is
practicable.
After you have prepared the land
very thoroughly and compacted it so
as to provide a firm seed bed then
roll and cultivate until you have Sc
| cured a filth as fine as that of a
garden. Next put at least two tons
of crushed raw lime rock per acre
on the ground and harrow it, in. Sc
cure some special cultures for the
| incubation of your seed and the day
you desire to plant the alfalfa pre-
pare these cultures and apply to the
seed. The seeding is best done in
the evening Or on cloudy day. Re-
| member the bacteria are sensitive
to bright sunlight and may be kill
