The Concrete.
The concrete sio is built exclusive

rods, OF woven wire. The first cost
of building such Il silo is rather great,
or than of building the oiHer types,
but for durability no slo can compare

Many things said Of concrete also

stave slios.
! Many manufacturers have made q
speciality of stave slos, and have given
them wide advertisement because OF
/ cheapnesS of construction, and of a
/ patented Joint door fitting
Is low cost, and ease of erection
/ lave made il the most widely built
type. All of the firms selling stave
Slos have good ones, but the patented
door feature has greater value ms
an agents talking point than 1t has
for the preservation of feed.
The stave silo keeps ensliage well
but Its principal disadvantage Is the
fact that its life is short Its 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 sil0, two types OF
which are In use, is the cheapest. One
type is constructed with oak or elm
hoops TO which matched tongue ant
gr0oved boards are nailed from the In
side. The inner wall thus is made
smooth. uniform and air tight.
TIE other type Is built with rougl
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 II properly con
structed, have essentials Of good silos
to-wit: they exclude air, and retair
moisture; have a smooth perpendicu
lar; and sufficient resistance to with
stand inside pressure and outside wine
force. Their life varies from eight Il
fifteen years.
Farmers frequently choose one o
these types because they have al
abundance of wood. the cost OF which
is therefore much less TO them. The
total cost, however, depends upon th'
size. Under present prices the price
ranges from S1.5O 10 SO for each tor
capacity
