Is proposed to construct Cat presently 1000
4 linear feet OF the open pile breakwater in Lake
Pontchartrain, opposite to the terminus of the
Pontchartrain Railroad, and at the distance there
from of $3.50 feet, and in Is feet water. Said
breakwater to be constructed according to the
plans and drawings in the hands of Major G. T.
Beauregard, Corps of Engineers, New Orleans
Major William H. Chase, Corps of Engineers Mo
bile; and Mr.. H. F. Ingraham, Pensacola. at each
OF which places they can be seen and examined
it Is 10 consist OF four rows of cypress or pine
plies IL In. square, driven from 10 to Is feet into
the bottom of the lake, which is composed of mud
and sand; the piles in each row being feet from
centre to centre; and the distance between the
three outer rows Chat is, crosswise) being 10 feet
from centre to centre; the inner row being inclined
80 as to act like brace buttress to the Others
by abutting against the top of the one next to it,
where they are to be halved into each other and
hrmly bolted together. The three outer piles in
cross section are to be connected together by an
inclined cross piece, IL in IL in strongly bolted
on to their heads, and intended also to receive a
4 inch planking, which will be securely fastened
on oy heavy spikes and trenails of Iocust this
planking is to be open; the panks being about i
foot apart and let into mortces about , inches
deep.
This plankng or platform rises on the inside of
the oreakwater to about feet above the low water
level OF the lake, and descends towards the outside
to about feet below the same level, thus present.
ing an inclined surface on which the wave will
break. -
connected her
longltudinally by string pieces, 10 in b in.
securely bolted to them. and supporting the in.
clined cross piece just spoken Of which will itself
be braced to the two inner rows (3d and 4th) by
norlSontal cross piece II in IL in, boted to
them Immediately below the low water level. The
construction under water will be executed as fol.
lows: After driving down the outside pile certain
distance the inclined piece is attached to it
Dy screw bolt, and 1t is then driven down to it's
proper depth, its head being cut off level with the
cross piece; the other piles are then driven down
and the cross and longitudinal pieces boted on to
them also. The fastenings to the middle pile can
be easily effected, as their depth below the low
water level will only be from Is to "a inches The
iour inch planks under water will be soiked and
trenaled to the inclined cross piece by means of a
tube and follower, the holes and mortices being
prepared before placing them in position
Quantity of materials for the construction of the
breakwater:
500 cypress or pine piles, IL in. 10 in, from
% to 80 feet long.
7'ooo running feet of cross and longitudinal
pieces, 10 in. x IL in.
" '0Oo running feet of planking, 4 in. - in
LIPS screw. bolts, galvanized iron,) from ] in
roo to i in. diameter, and about % in. long
$500 trenaiIs of locust. sd
1t Is supposed that the work can be carried on at
