Permanency in construction is al
ways one of the basic principles of
economy. We find that weirs con
structed OF wood last from three to |
six years, with an annual maintenance |
Of more or less expense. weir that |
will last indefinitely can be construct |
ed OF concrete. at moderate first cost,
and no maintenance charge.
First. determine the position of
your weir and the maximum amount
Of water you expect TO discharge
through it. This having been done,
sxcayate the ditch to level surface.
to depth of four OF five inches be-
low the original bottom. The length
of the base will be. in our case. say.
eight feet. At each end of the foun-
lation pit make small trench,
reaching across the bottom from side
10 side. The width of the foundation
viii depend upon the size of the weir
needed. Assuming a two-foot weir.
we would make the base five and one
half feet. Now mix your concrete,
)ne part Portland cement, three parts
sand. and six parts gravel or broken
stone. and place this in the pit as
/ provided. The small trenches at the
ends will serve as a curtain wall and
prevent the water from flowing be-
leath the base. While the concrete
S being placed there should be set a
scantling two inches square and full
ength of base, directly underneath
~.
weir Now place four onehalfinch
ron rods in the base, TO extend verti-
,ally on the outside OF the scantling,
and to extend some six or eight inches
above the finished surface of the base.
I is advisable TO bend the ends of
.hese rods at right angles, the lower
end extending out into the base at
light angles to the axis Of the ditch.
These rods should be equally spaced
with first and last one a foot from
each end Of the wall. The two
scantlings will be parallel with each
other, and after the concrete has al
been placed and tamped into position
and noated with straight edge. these
strips should be flush with the sur
face. There should be margin o
concrete on the outside Of them a
east four inches wide The finished
surface should be approximate.

The forms for the sides OF the wei

each side wall. At the ends of the on
side pieces are two long eye holt
, reaching to the opposite side Thes
, bolts are threaded for some distance
- permitting of varying widths. To forl
, the ends OF the wall is placed vert
cally board. five inches wide. w
feet long. held in place by cleais. Tw
pieces Of PA at each end, cut Il
proper length. serve as struts

. struts are in place. the turn nuts {
the eye bolts are frightened, thus eau
= ing the whole form to be rigidly co
nected and properly spaced. The Q,
bolts are hinged at the diagonal &C
ners and the end pieces are slotted

4 side wall a 2iax2-inch cleat is nail
vertically on the inside of the insi

and to prevent excessive leakage.
Ut small angle iron. placed on the low
side OF the clcat. and imbcdded in
