siIo, any material ma be used which
is sufficiently strong and durable to
Withstand the pressure exerted by the
silage. and which may be made air
tight. so IS to keep the silage from
spelling.
In sections where good building
sand and gravel arc available, con.
crete blocks of various forms may be
moulded and used in silo construction.
Of these there is a great variety from
the common cement hollow blocks,
to the concrete stave. In places,
where sand is available. forms could
be bought and used for. moulding
these, and the silo constructed with
very little cash outlay. And in many
cases, where the freight would not be
excessive on these different forms of
concrete blocks or slaves, such silos
can be- constructed very reasonably.
When properl, constructed there can
be no question as TO their dura bilitS,
and ability to keep the silage salts
IA ctorily.
Brick and Tile Sflos. 81 u,
Brick is a ~favorite material for
| building silos, Silos built of such
material Of purse vary from the or
binary building brick to the hollow
tile silo, a form of which is known
ss the Iowa Si!o. and has given
splendid satisfaction. Those hollow
tiles arc moulded for different sizes
of silos, and have the advantage of
being easy to construct and the claim,
is made for them that they Withstand
freezing to a greater c2:,n, than some
other forms OF slios.
Where building brick is available,
it may be used to good advantage,
and there is 10 form of brick siln
which apparently is not satisfactory
when properly constructed. One rf

cription Of building i brick and rein

wall was built, and as the wall wcnl
up, 20 penny spikes were laid in tho
joints, about . fect apart, with the
heads sticking out about a half incl
on the inside OF the silo. These nail:
had been burned before placing then
in Inc wall, SO that they would bend
easily. After the 1 inch silo wall was
completed, heavy w fence wire
was cut the proper length to reach
around the silo. and hung on thest

Reinforcement Essential
In all brick, stone OF concrete blocl
silos some provision must be made 70
reinforcement. There have been
? number of silos badly damaged in thi
section because this ~precaution wa
not taken. The Iowa si!o. or hollow
tile type. provides for the use O
, heavy wire between every course o
tile. This same precaution should b
taken with brick. stone or any othe
form Of silo. Some of the concrct
block silos ave provisions made fo
this reinforcement. Rods are rnoulde'
into the blocks. Sc that when tn
blocks are put in place the rods ar
CONNECTED together in such away a
to form a perfect reinforcement. Thi
obviates the use of hoops IN the out
e side. and certainly is a satisfa ctor
means of reinforcement.
