to produce the maximum effect at minimum cost
Will also remark that, not designing to have any il
terror bitches or canals Immediately next to the exte
rior levees, no filtration waters, which are general
go troublesome and expensive, need be apprehended
said levees are kept in good condition. So soon
any Of these levees are finished, earnestly recon
mend, that Bermuda grass seeds or cuttings shoul
be sown on their crest and slopes to protect then
from the effects Of the sun, rain and high waters
the lake, during Northerly storms. This grass mat
ting when thick, as it will soon become, will ever
prevent weeds and bushes from growing on tn,
levees. ss
The planting of several rows of suniowers (helian
thus) along the berms Of every canal would, accord
ing to Lieut. Maury u s. Navy, cause the absorption
Of the miasmatic gases, arising from these canals
when the latter neglected not cleaned out and
would remove, if successful one Of the greatest OBJ
jections to their use in large cities.

They present together, in each section an average

cubic feet to an acre.
In order to place the draining engines Of the last
four sections in the most favorable locality to do
their work adyantageousy. by diminishing as much
as practicable the distance the water has pass over
in getting to the draining wheel Of each section, it
becomes necessary to construct central discharge
canal, along the middle Of Orleans street Nelson
Ayenue), to carry of to the lake the discharged va
ters Moreover, it might be used hereafter for the
same purpose, for sections and if necessary.
This canal would thus be situated about halfway
between the New Canal and Bayou st. john its di-
mensons should be such also to furnish the earth
required for the protection evees each side Of it.
should be SO feet wide at top, 80 feet wide at
bottom, and feet Deep its length from the middle
point Of the line Of separation of sections and to
the lake would be about 1O,250 feet The foot Of |
the outer slope Of those leyees must be at least 10
feet from the edges Of the canal.
The draining engines Of sections 8 and ought to
be placed near the upper extremity of that canal,
discharging their waters into it. Those of sections
and ought to be put for the same reason as near
to it as practicable at about the middle distance be-
tween the first two sections and the lake. The en-.
gnes thus placed near each other two in each ocaIi
~, will require but one engineer to each set and can
be arranged to drain the contiguous sections in
Of necessity But they should be put far enough
from each other, to be beyond the reach of danger,
should Of them be destroyed by fire or by an ex
plosion Of boilers.
The entire separation from each other, or more
properly, isolation of these sections by their levees
enables to complete the draining arrangements of
my one Of them independently Of the Others and
recording to the means at our command, leaving the
lranage of the others to be commenced and COM
,eted as circumstances will permit
The Board OF Commissioners must decide to which
the sections referred to in this Report the means
present available shall be applied and the order
which the others shall be undertaken. /,
By referring to the accompanying detailed estimate
will be seen that the perfect drainage of the First
istrict, comprising ,430l acres will cost as follows
