by New One, 20 Feet High,
and z Feet Wide
INTERESTING ITEMS or
PROGRESS ALONG LEVEES

Con r"tp NOrk preparatory u
raising and widening the present
stone wall between Fourth and
Eighth streets was begun yesterday
by the Walsh-Kahl Construction
company from Eighth street south.
Laborers who mix the concrete b.
hand are throwing it into trenches
that have been dug twenty feet be-
low the base Of the old wall The
bed of concrete at the bottom Of the
trench which will form the founda-
tjon of the new wall, is two feet
wide and will continue up the outer
side of the Old concrete from two
feet to foot and a half in width
and viii rise about four feet and n
half above the top of the present
barrier. From the base to the top.
the new wall will measure about
twenty feet
Reinforcing work.
Steel reinforcing rods are forming
the skeleton work for the new wall
end they are being laid both hori-
zontally and vertically in the newly
mixed mass OF lime, sand aud stone
When the concrete in the trenche
is brought up to the base of the old
wall it will be anchored to tha
stone with steel rods A compressed
air drilling outfit is on the scene
now and will be put at work as soon
as the concrete work progresses sut-
ficiently to drill into the present
wall
Unlike the other stretches Of the
Ohio levee front, the wall from
Fourth to Eighth street Will not be
built over the interlocking sheet
piling that is being driven into tn.
earth along the other portions. Thi,
is because the lcyee slope here /
sufficiently solid and wide enough
for the resistance of the underneath
pressure and there is no danger o.
undermining by quick sand stratas
However, from Fourth street soutf
to the Halliday elevator, the p'linr
viii be driven in the same manner
as the work is now being prosecuted
north Of Eighth street to the Cair-
elevator.
Manv Machine Mixers.
In several days, the concrete wor'
: between Fourth and Eighth street
which is now being done by ham
will be done by the concrete miXine
machines that are on the grount
and which are being put in shap'
| for the operations When the worl
| is in full sway all along the leve
/ front there will be a half dozen o
more concrete mixers in operation
Just now the trenches for the
new wall work south of Eight
street are being dug about five fee
apart to relieve the pressure Of tn
wall on the excavations and pre-
venting any cave in of the old con
crete
| When the old wall was put dow
some fifteen years ago, reinforcer
concrete was not known and tn
work was done by the old method
The modem ideas in constructinl
the new wall should make it mucI
more stronger anG more lastin
than the old, according to the stat
engineers who are supervising tn
job,
Work North of Eighteenth.
North of Eighteenth street wor
on the new wall progressed rathe
slowly yesterday but much car
must be exercised in the startin
for the work there is constructor
an entirely new wall and not tn
rebuilding of an old one, since tn
present wall only runs to Eigf
teen street The work is being don
in much the same manner as tina
south of Eighth street.
! The interlocking sheet pilin
work is going ahead rapidly bot
| between Eighth and Fourteent
streets and above Twenty-secon
street where one pile driver
steadily on its way to a point nea
the Cairo elevator.
