same apparatus that is ordinarily used
In handling other feeds. A lean-to or
shed could be built over the silo to
protect it in cold weather.
Laying Out the Curb.
Tho actual beginning Of the con-
struction Of the pit silo is the use of
q IA or 1x4. a little longer than one
half the diameter Of the silo. one end
Of which should be fastened at the
exact center Of the silo. 80 It can be
revolved about this point. Then out
from the center feet. q 80 penny
spike can be driven through this
board. Eight to ten inches farther out
another should be put in, or holes
bored and small bolts dropped in. for
the purpose of making two marks. 8
this marker about tho center. q trench
is dug between these marks. for the
curb Of concrete which is filled in the
trench, the same as for the founda-
ton Of any building. This concrete for
the curb may be made I to 8. II good
sand and gravel 10 available, and
should be put in wet !.
After this concrete has set the soil
is excavated inside the curb, the
about feet q reamer can be installed
for trueing down the walls for plas-
tering. This rsamer is made Of a 2x4
with q knife on one end. and fs re-
volved about q gas pipe. held per-
pendicularly In the exact center of
the silo. This knife cuts away the
dirt, and gives uniformly true wall,
sisting Of / Of cement to Of sand Is
plastered right into the dirt wall.
Two good coats Of plaster should be
applied, as it should be about one inch
thick.
After the first section Of the silo is
dug and plastered. another feet can
be excavated and treated In the same
way.
Erect q Derrick.
It II Of course necessary to arrange
some sort Of derrick for hoisting the
dirt, and as there is a great deal to be
hoisted the arrangement should be
such that q horse or engine can be
used for this purpose. The figure ~"
hoist, cut of which Is shown. has
proved very satisfactory. for this pur-
pose, and is also used later for get

Cement the Bottom.
When the silo is completed it 10
generally advisable to cement the bot
tom, also this IL not absolutely neces-
sary. It 10 also Of great advantage to
build a curb 8 feet above ground for
tho purpose Of keeping out stock. and
also to make it more convenient to ar
range cover with doors.
Build Curb Above Ground.
For building the curb q section Of
form. 8 to z feet long, can be built
and set up ON the curb. This curb
need not be as thick as the founda-
ton in the ground, though perhaps 8
inches would be az thin as 1t should
be built. The inside of tho curb above
ground should Of course be Just even
with the inside below ground, SO that
there would apparently be a continu-
Gus wall. When this section Of curb
is built, the form can be removed and
set up at ono end, and another section
built. Some reinforcement should be
used II q si1o is to bet set on top Of
the curb. II q short wooden silo IL to

brush coat fills up all pores in the
wall, and makes 1t perfectly alright.
The brush coat should be applied once
q year. just before filling, to keep the
walls in good shape.
Getting tho silage Out.
With many. getting the silase out
Of a pit silo is q great bug-a-boo."
However, We have found that with z
conveniently arranged hoist there Il
very little difference in the time re'

and from ono above ground Tho dif-
ference Is 50 slight that 1t can be
practically disregarded.
