chase the lumber, match 1t, and con-
struct temporary s!lo.
Most people prefer to purchase the
matched lumber from some reliable
silo manufacturer The lumber is
matched and fitted, and can be put to-
gether by anyone who has only slight
knowledge of carpentry work The
doors. hoops, lugs and everything
needed are furnished The stave silos
are usually built from tongued and
grooved in. In. or in. In.
material. About every three feet,
Iron hoops linked together with lugs
surround the silo. The outward press.
ure OF the stlage ten feet from the
top Of the silage is little over 100
pounds per square foot The outward
pressure twenty feet from the top is
about 2s0 pounds per square foot, and
the outward pressure about thirty feet
from the top is about 33o pounds per
square foot. To make the silo suffl-
ciently strong to Withstand these var4-
Gus pressures, the iron hoops are
placed closer TO each other nearer the
bottom OF the Stlo.
Tho sflo should be smooth on the
inside 30 that the silage can settle
without any interference Often the
silo Is placed in the center Of the
foundation. which interferes with the
settling OF the silage below the foun-
dation. The inside Of the sllo should
be even with the inside Of the founda-
:ton. Especially is this important
where portion OF the silo IL excavated
down In to the ground.
The silo should be located near the
barn handy for feeding and ON wen
drained place. II so located, portion
Of the silo may be below the surface Of
the ground. The excavation should
not be too deep, as this makes 1t un-
handy to get the silage out. This un.
dersround part should be plastered In
a similar manner as is a cistern. Seep
age water will spoil silage.
The foundation should be built on
solid ground, and may be built from
stone laid In cement mortar or from
solid concrete. BY excavating a hole
In the ground about six feet in depth
the bottom of the foundation will ex-
tend below the frost line. The foun-
datfon can be made exactly circular
by nrst driving stake In the center
OF the place where the silo Is to be
located. Then fasten the end of a
measuring stake to that center pivot

the diameter, swing around and mark
the ground. Then increase the meas

OF the foundation. II the silo Is ex.

ton is needed.
Silos may be built square. octagon-
al, and round in shape. Generally
speaking the round form is the only
one now being built. 1t is almost i'm
possible to build silos in any other
shape so they will not spread.
Stave silos must be we'll anchored
with guy-wire to prevent them from
blowing down on windy days.
Dimension ana Size Of Silos.
In shape silo is then similar to a
very tail tank or tub. It should be
high in proportion to width or diane
ter, or about twice as high as 1t is
vide. The deeper the silo the greater
will be the pressure on the silage.
This excludes air and causes the silage
to keep better. More silage can also
be stored per cubic foot
The dimensions depend upon the
amount of silage needed or upon the
number of cattle and the length OF
time they are to be fed.
The average COW consumes between
30 and 40 pounds Of silage per dav.
In South Dakota silage can be fed
economically eight months Of the wear.
equivalent to 240 days. At 40 pounds
per day. each COW would consume
nearly fiye tons. Ten cows would
consume 80 tons. and 20 cows 10
