PontohaFsfain Railroad, and at the distance there
from OF $3.50 feet, and in IL feet water Said
breakwdter to be constructed ACCORDING tn H.

Of which places they can be seen and exam;nsd
1t Is to consist of four rows of cypress or pine
piles IL in square, driven from 10 to Is feet int
the bottom OF the lake, which ia coYnnosed ~ 80
and sand; the piles in each row being feet from
centre to centre; and the distance between ,ha
three outer rows Chat il, crosswisc) being 10 feet
from centre to centre; the inner row helms ;ncl;ad
so as to act like brace or butress To- The otnars
by abutting against the top of the one nert 70 ~
where they are to be halved into each ohio, snJ
hrinly boited together. The three outer piles in
cross section are to be connected togethsr hv an
inclined cross piece, IL in. IL in strongly ho,ted
on to their heads, and intended also to receive a
inch planking, which will be securely fastened
on by heavy spikes and trenails of locust; this
blinking is to be open; the planks being about
foot apart and let into mortices about 2 inches
deep.
This pIanking or platform rises on the inside Of
the breAkwater 10 about feet above the low water
level of the lake, and descends towards the outside
to about feet below the came level thus presente
ing an inclined surface on which the wave will
break
The two middle rooms will be connected together
longitudlnally by string pieces II in II in
securely ooted. to them. and supporting the in
clined cross piece juet spoken of which will itself
be braced to the two inner rows sd and 4th) by
horizontal cross piece IL in. IL in. bolted on to
them Immediately below the low water level The
waite will no
lows: After driving down the outside pile certain
distance, the inclined piece lie attached to il
by screw bolt, and it is then driven down to its
proper DEPTH its head being cut off level with the
cross piece; the other piles then driven down
and the cross and longitudinal pieces bolted on to
them also. The fastenings to the middle pile can
be easily effected, their depth below the low
water level will only be from Is to 24inches The
Jour inch planks under water will be spiked and
trenailed to the inclined cross piece by means of
tube and follower, the holes and mortices being
prepared before placing them in position. US
breakwatef:
5O0 cypress or pine piles, IL in. x IL in, from
% to 33 feet long.

asfl pieces, IL in. x IL in

1t is supposed that the work can be carried on at
the rate OF 200 days in the year without interrup-
ton from the weather, after making fair allow
ance for other casualties and Sundays. 1t will be
required to be completed in six months from the

LIST To furnish and deliver at the site of the
breakwater, or about the Pontchartrain Railroad
Depot, las the experimenting engineer shall di-
rect ali the piles the cross and longitudinal pieces,
and the planklng needed for its construction
I'd. To construct said breakwater at so much per
running foot OF ls length, the contractors furnish
ing every thing elee but the piles, the cross and
longitudinal pieces, and the planking
Sd. To furnish al the materials &C. required
and TO construct the whole breakwater at so much
per running foot Of its length; in other words to
