PontchaFtraint opposite to the terminus of the
Pontchartrain Railroad, and at the distance there
from Of $3.50 feet, and in 10 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 b. Chase, Corps of Engineers, Mo-
bile; and Mr. H. +. lngraham, Pensacola, at each
OF which places they can be seen and examined
IT. TO consist of four rows of cypress or pine
piles 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, crosswse) being 10 feet
from centre 70 centre; the inner being inclined
so as to act like brace or buttress to the Others
by abutting against the top of the one next to il.
| where they are to be halved into each other and
firmly bolted together. The three outer piles ia
cross section are to be connected together by an
inclined cross piece, ~ IN II in, strongly bolted
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
| panking is to be open; the pianks being about
| foot apart and let into mortices about inches
| deep.
| This planking or platform rises on the inside of
| the breakwater to about feet above the low water
level the lake, and descends towards the outside
to about feet below the same level thus present.

break
The two middle rooms will be connected together
longitudinally by string pieces, IL in. u in,
securely bottled to them. and supporting the in,
clined cross piece just spoken of, which will itself
be braced to the two inner rows I'D and 4th) by
horizontal cross piece, IL in. IL in, boted on to
| them Immediately below the low water level The
construction under water will be executed as fol.
lowe: After driving down the outside pile certain
distance, the inclined cross piece il attached to it
by screw bolt, and it 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 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 "a inches. The
four inch planks under water will be spiked and
trenailed to the inclined cross piece by means of q
tube and follower, the holes and mortices being,
prepared before placing them in position
