FIG. I-FOUNDATION.

bottom should extend to the level of the floor
upon which the stock is fed. The round silo
of wood may be set upon a stone basement ex-
tending eight or ten feet below the surface of
the ground as readily and with the same adj
vantage as any other type. Indeed, l would
urge the general practice of sinking the bot
tom Of the silo at least two, il not three, feet
below the bottom Of the feeding stable, wher-
ever the ground is dry enough to prevent wa
ter from draining into it.
In Fig. 2 is shown one method of laying and
leveling the foundation wall where it is only
two or three feet high. A is a center post with
its top level with that of the proposed wall;
BIB, boards nailed to stakes, their tops level
with that of the center post, and G is a straight
edge which turns on q pin at A. A simpler
method Is to drive down a stake like a fOrh
handle at the center and then bore through a
board a hole large enough to slip easily over
the stake; then, OF cutting this board to the
turned about in determining the position of
the outer edge of the latter. When the wall is
once started it can be laid up with the plumb
or level like any other. In bringing It to u
level a long straightedge may be used, reach
ing from the center to the wall, or it may be
laid upon the wall directly, stretching from
point to point like the chord of a circle, Tie
top of the wall inside should be leveled SO as
nearly to meet the lining of the structure
above. as shown in Fig. 2.

silo. Stills 2 by As cut in sections on q radius
of the silo circle, bedded in mortar and toe
nailed together. Plates the same. spiked to
tops of studding. studding 2 by IS one foot
apart. Short lengths may be used, Tapped, to
get the depth; l6's and las will give a
silo thirty feet deep. Lining made from fencing
ripped in two. Outside sheeting the same.
Siding for silos under thirty feet outside di-
ameter, common siding rabbetcd; for silos
more than twenty-eight feet outside diameter,
common dropsiding or shiplap may be used.
A shows ventilators between studding. Anger
holes are bored ut bottom between studding,
and the boards lack two inches of reaching
plate at top, inside. Both sets of openings are
covered with wire cloth to keep out vermin.
There should be a line of feeding doors from
top to bottom, each two to three feet by five
feet and about two to five feet apart.
The stills and plates are most simply mad
by cutting 2-inch lumber, of the same width
as the studding, into sections Of from two to
four feet long, according to the diameter OF
the silo, saving on the bevcl determined by
the direction of the radius of the circle; those
for the stills are bedded in mortar and toe.
nailed together, and those for the plates spiked
down upon the top of the studding.
Where the silo does not exceed thirty feet
in diameter 2 by 4 studding gives ample
strength, and in no case is it necessary to use
studding larger than 2 by @. The use oil
the studding is to hold the lining and siding In
place and to support the roof. In the rounG
silo the strain from the ensilage is sustained
by the lining and siding, each course acting as
ahoop. The distance between the studding in
silos less than thirty feet in diameter should
be one foot. In those over thirty feet the stud
ding may be sixteen inches apart. After the
stills are placed the studding should be toe
nailed to them just as in q balloon frame, and
each stud plumbed and stayed with a board
nailed to a post set in the center of the silo
After plumbing and staying the studding ii
this direction, it may be stayed in an opposite
one by springing A-inch boards around ant
lacking them to the studding.
The lining should be of H-inch lumber, ant
may be obtained by splitting fencing in 1--WE
or by a special order at the mills. Two thick
nesses, with a layer of good tar paper between
are required. and the two layers of board!
should break joints. Experience may show i
best to use three layers of H-inch lumber will
two layers of tar paper between to secure per
feet ensilage next the wall, but the additions
layer may be added at any time.
The siding may consist of two layers will
paper between where the temperature of win
ter emands them. When the circle is les,
than thirty feet H-inch lumber should b,
used, and the siding must be rabbeted to lie a.
shiplap does. Common house siding, rabbeted
answers every purpose. and is made to ordel
by some mills. Where the circle exceeds thirt,
feet in diameter drop siding may be used, tha
of the shiplap type being most easily put on.
The mailing inside and out should be thor
ough and in every stud. because the boards
act as hoops and the lengthwise strain comes
upon the nails; for this reason also the board'
should be made to break joints on the stud
ding. For the inside lining, it is better to us,
1O-penny nails for the last thickness 80 as t.
draw the layers tightly together, and in nail
ing the lining be careful not to miss the stud
ding, as every nail hole thus formed will I'D
NIT q large amount of air.
