A CIRCULAR SiLO.
1t Will House 2o7.63 Tons of Ensilage and
Cost About $500.

O~~S
In a pamphlet on silos and ensilage
Mr.. James W. Turner presents the speci.
fcation and estimate of cost for the con.
struction of circular silo of 207. So tons
capacity. A capacity of this size is suit.
able for the maintenance of about sc
COWS or the equivalent of this in any
other stock. The construction is such
that this capacity can be greatly in
creased without increasing the diameter
Of the silo by simply adding to the length
Of the studding.
Excavate trench for wall not less than
8 feet deep, of sufficient width to allow
the wall to be laid, without the earth
touching the stone until the mortar is
set. Throw the earth from the trenches
to the outside This will be used to
grade and fill around the building. The
wall should start from solid ground OF
a bed of concrete and should be well
built Of large stone in the manner of a
4 barn wall The mason should see that
the bond timbers, Of by s hemlock
plank, sawed on the outer edge to a ra-
{ dius Of 10 feet, are firmly bedded in the
mortar and in perfectly level position.
Bolt the bond timbers to the walls by
means Of quarter inch bolts, "a inches
long, turned up at the bottom, with not
less than three bolts to each length OF
bond.
The carpenter should see that the bond
timbers are ready for the mason, anG
that the plates will be placed not more
than 16 inches on centers; the opening
should be about 8 feet wide and triple
studded; the opening should be spanned
by at least ten quarter inch bolts of suf
ficient length to bolt through the three
studs on each side; the bolts should be
fitted with large washers; all plates and
rafters should be thoroughly spiked to
their bearings; the plates should break
all joints by as nearly one-half theil
lengths as possible; the roof boards
should be laid not more than Is inches
apart and fastened by at least two nails
to every bearing Shingles should be laid
inches to the weather and have two
nails each.
The lining (see section) will be made
of two thicknesses Of half inch boards
laid to break joints by one-half Of their
width. These should be firmly secured
to every bearing and have thickness OF
tarred paper between the boards.
The outside covering may be Of five
eighths inch novelty siding, or may be
sheathed diagonally and shingled or may
be covered with corrugated iron. Before
the covering is put on there should be a
thickness Of tarred paper spread over
the studs from top to bottom. Every
joint should be over a stud and should
lap, say, two inches, and be well nailed.
The silo should have one or more dor
mer windows, with sash hung SO as to
swing in. They should be fitted with
suitable bolts, etc. The valleys and
joints Of dormer and main roofs should
be we'll flashed with good tin. The open
ing Of silo shoald have jambs fitted tc
receive boards as they are required in
filing or using from the silo. The in.
terror should be given good coat Of
hot tar and pitch.
The estimates Of material and labor
as found about Lansing, Mich, make
it appear that this silo, "a feet in diam
eter and 81 feet 10 inches in depth, costs
nearly 5000, but in many localities the
cost would not be so great.
