Jollv Hill Project.
The plan here
propased
is to provide
a 2000 acre foot
re-
servoir
by the
construction
of a
dam
to
a point locally
kaown
as Jolly
Hill-See
Plates
''A’’ and 4.
There
is at
present
a small
diversion
structure
at
this point
and
an
18"’ concrete
pipe
leading
there-
from
to a
small
concretelined
reservoir
and
thence
on down
to the lands
of
the
la Grange
Sugar
Factory.
A
variable
radius
arch dam
is droposed
at
this point
with 2 maximam
height from stream
bed
to spillway crest
of about 90ft.,
or to ele-
vation 250.
A 400 fr. top radius
would be
required,
and the
erest
length of the
dam
89 feet.
The
maximum probable
flhw is
estimated
as
a
10077 runoif
from
a
two
in~h per
hour rainfall
over
a
water
shed
of 2 08
sip. miles,
or
a
flord of 240
sec,
ft.
This
would result
ir
a depth of about
1.5 ft. over
the
spillwas.
There
is sohd
rock exnosed
in the
bottom
of the
wash
at this point, and
the soil is very shaliow
on the slopes.
IThe rock
1s of the hardest
variety
of the
old=r
for nation
ard
ap-
pears
quite suitable
for the foundation
of
an arch
dam.
As
a precaution
arainst
open
seams,
however,
it
is planned
to
excavate
the
foundation
to an
average
depth
of 10 feet,
and
to
seal
the
cracks
below
this by drilling and
cement
grout-
ing under
pressure.
Good
concrere
ag-
grerate
can be obtained
at the
dam
site
by erushing
the local rock,
or sand
and
grravel can be
secured
from
the
sea
beach
which
ils the
usual
source
of supply
for
eoncrete
work
on
the
Island.
The
sea
heach
gravel is of good
quality, but
the
sand
would
not
stand
a very
high
test
thongh
a fairv
good
grade
concrete
s
mad-
fromit.
A2%
inch
cast
iron
pipe
outlet
is
proposed
through
the
dam
at
elevation
180,
or under
a maximum
heud
of Toft,
This
will
be
provided
with
a
valve gate
at the
outlet
end,
and it will
discharge
into the natural
rock
channel.
A short
distarce
below the dam,
or about
opposite
the
present
small
reservoir,
a
small
diversion
structure
is
proposed.
From
this the J
-1 and J-2 cana's
will
di-
vert, the former
running
to
the

as far as

for

FACTS AND TRUTH MUS{ PRiEVAIL

An ariicle appeared

The
Tribune
says
that
{
am
unknown
in political cireles;
this staement
1s rue
for if one
does
not
agree
with
the
aims
and
views o’ the Tribane
and its nulitical
¢.rele
you are considered
Jdead.
Now
as regards
the polities and
politi-
cians
of the
Tribune,
the
sireet
¢ rners
and gallery telk
is the
politics
and
the
Tribune’s
atmosphere
and
one

who
go around
talkirg
a whole

and when

“hat’s the polities and
political
circles
they
belong
to
and
talk about.
They
called
me
a
political
tool and
turn
around
and
say
[
am
unknown
in
political

is it not
strange
that
one can be
a
political
tool
without
a
political cirele?
