(which type shall 1t be?" Is one OF
the perplexing questions which faces
the farmer who anticipates building a
silo. He wants to combine service
with cost, and therefore thinks much.
Four kinds of sllos are being built,
all of which are successful, but many
farmers are of the opinion that the
concrete is the cheapest and most sat
isfactory when its long life is con-
sidered. The other three types are
the vitrifed tile, the .stave and the,
wooden hoop.
The Concrete.
The concrete silo is built exclusive
ly of cement, reinforced with iron
rods, or woven wire. The first cost
of building such silo is rather great
er than of building the other types,
but for durability no silo can compare
with it, Therefore the cost can be
spread over a long period of years
Other advantages are, it cannot burn,
blow over, rot, or allow vermin to en-
ter.
vitrified Tile.
Many things said of concrete also
can be said of the yitrifled tile, ma
terial out of which most efficient
silo can be built Initial costs vary
very little.
This type will last indefinitely, will
resist storms if the tile is properly re.
inforced and will deteriopate very lit.
tie from temperature fluctuations,
Inner walls, however, from this type
of silo, sometimes are left with jags
underneath which air pockets form as
the silage settles and hangs. This can
be avoided, though, by using precau.
tion in the construction of the inside.
No prospective builder will make a
mistake in selecting a vitrified tile
silo.
stave siIos. -
Many manufacturers have made
speciality of stave silos, and have given
them wide advertisement because of
cheapness of construction, and of
patented joint door fitting.
It's low cost, and ease of erection
have made it the most widely built
type. All of the firms selling stave
Silos have good ones, but the patented
door feature has greater value as
an agents talking point than it has
for the preservation of feed.
The stave silo keeps ensliage well
but its principal disadvantage is the
fact that its life is short. It's useful
ness, however, can be prolonged by
the frequent use of paint, and the
tightening of guys and hoops. Woods
to be used in construction which give
the longest service are mentioned in
order: red wood, cypress, Oregon fir
and Southern yellow pine.
The wooden hoop silo, two types OF
which are in use, is the cheapest. One
type is constructed with oak or elm
hoops to which matched tongue ant
grooved boards are nailed from the in
side. The inner wall thus is made
smooth, uniform and air tight.
The other type Is built with rough
lumber nailed to the hoops. Inside OF
the 'barrel" is then covered either
with wooden or metal lathing, to which
one-half or three-fourths inch of plas
ter is applied.
Both of these types, If properly con
structed, have essentials of good silos
tO-wit: they exclude air, and retain
moisture; have a smooth perpendicu
lar; and sufficient resistance to with
stand inside pressure and outside wind
force. Their life varies from eight tc
fifteen years.
Farmers frequently choose one OF
these types because they have ar
abundance of wood, the cost of which
is therefore much less to them. The
total cost, however depends upon the
size. Under present prices the price
ranges from S1.50 to 81 for each tor
capacity.
