Section of Sidewalk.

costing $l.50 or two dollars will lay 80
square feet of finished walk
For the sake Of illustration assume
that walk is to be built three feet
wide and four inches thick, concrete
go inches, top mortar three-fourths of
an inch. First, excavate trench three
feet four inches wide. If an open or
porous soil four inches below bottom
or eight inches below top surface of
walk, but if in clay soil this trench
should be eight or ten inches below
bottom of walk From the lowest
point of trench lay tile so no water
will stand in trench TO freeze. Now
fill this trench with cinders, gravel, or
stone, even. and lamp; when this is
brought up within four inches of the
top surface of walk the porous foun-
dation is complete. Now place side
forms (scantling, 2x4 inches, set on
edge. Stretch line tight, and from
line set scantlings straight also they
must conform to proper grade line.
Secure these scantlings firmly by
placing cross scantling every four
feet and securely stalking the outside
ct each of these cross scantlings to
keep them from spreading while the
concrete is tamped into place. Use
no nails or spikes; or in removing be,
fore thoroughly hardened the cast
might be broken. The surface into
which the concrete is tamped is first
sprinkled SO that the dry surface will
not absorb the moisture from the con-
crete and thus arrest hydration. Mix
concrete for the 3A inches in the fol-
lowing way: Take one part Portland
cement. three parts sand (clean
coarse and fine mixed), and four parts
aggregate (this may be gravel,
screened cinders, or crushed stone)
Place them in one pile on mixing floor
While dry shovel back and forth at
least two times, until thoroughly
mixed. Now sprinkle with sprinklng
can while IL is shoveled back and
forth two more times or until evenly

ready TO place. Shovel into the sec
tons Of the form, beginning at one
end and filling each section as you go,
tamping thoroughly and evenly to
within threequarters of an inch of top
Of form When the first section is
completed remove the cross scantling
and against the joint thus left bare
set board one-fourth of an inch thick
and projecting above concrete so that

moved, thus leaving one-fourth of an
inch division between each block.
This is important. The board is now
moved forward to the next joint. and
so on 10 completion. With knife or
pencil mark side forms exactly over
the one-fourth of an inch open joints,
so that when the top mortar is spread
continuously over the surface the top
mortar may be cut through into the
lower joint or opening with trowel
sliding along straight edge. The work
must be so managed that the top NOR
tar can always be placed on the con-
crete within two hours after the latter
is placed, also the concrete should be
slightly sprinkled before the mortar
is placed. so that the surface is moist
Make mortar for top as follows: Port
land cement, one part; sharp. clean
sand two parts. First mix dry then
wet and work into a stiff mJrtar.
Place this on the concrete. spread with
trowel, leaving the form rather full, so
that when stroked even with straight
edge the form is even full everywhere
Leave for 20 minutes, when the
water will be evaporated. At this
time finish surfaces smooth and even
with float or trowel, but do not over
trowel, which again brings the water
to the surface. Run along each side
edge with edger, cut across joints with
trowel and straight-edge' at marked
points. run iointer through these, or,
in. the absence of either edger or
jointer. dub the edges with trowel.
After "a hours cover with grass.
straw, or = carpet. wet thoroughly
twice each day for six continuous
days. when the walk is ready for use.
