Pontchartrain, opposite to tho terminus of the
Pontchertrain Railroad. and at the distance there
from of $3.50 feet, and in Is feet water Said
breakwater to be constructed according to the
plaas and drawings in the hands of Major G. r.
Beaurekard, Corps Of Engineers, New Orleans:

of which places they can be seen and examined.
1t is to consist OF four rows of cypress or nine
piles IL in. squares driven from 10 to Is feet into
the bottom of the lake, which is composed of mnd
and sand; the piles in each row being feet from
centre to centre; and the distance between the
three outer rows hat 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 H.
where they are to be halved into each other and
firmly bolted together. The three outer piles in
croes section are to be connected together by an
inclined cross piece, 10 in. < II in strongly boted
on to their beads, and intended also to receive a
4 inch planking, which will be securely fastened
on by heavy spikes and trenails of locust; this
planking is to be open; the planks being about
foot apart and let into mortices about 3 inches
deep.
This planking or platform rises on the inside of
the breakwater 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.

The two middle rooms will be connected together
iongit9dlnaily by string pieces, IL in. 10 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 ed and 4th) by a
horizontal cross piece, 10 in IL in, bolted on 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 lis attached to Il
BY screw bolt, and it is then driven down to its
mr. cy,th ito hond hoiv
cross piece; the other piles are then driven down
and the cross and longitudinal pieces bolted 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 24inches The
four inch planks under water will be spiked and
trenailed to the inclined croas piece by means of
tube and follower, the holes and Inortices being
prepared before placing them in position
Quantity of materials for the construction of the
breakwater;
500 cypress or pine piles. l2 in. 70 in, from
% to 80 feet long.
1000 running feet of cross and Iongituudinal
pieces, 10 in. x 10 in.
% 900 running feet of planking 4 in II in
1, l25 screw bolts, galvanized iron,) from in.
to Il in diameter, and about IS in long.
$500 spikes.
800 trenails of locust.
1t lie supposed that the work can be carried on at
the rate of 200 days in the year without Interrupt
