etc. A great number of answers we're
obtained, and the results are tabulated
in the report. These tables point unmis-
takably to the following facts: First
That great portion of the lands lying
south Of the city are suitable for irrigs-
ton purposes. Second-That an insult
ficient amount of land is offered for q
disposal Of the city's sewage.
enough land is, however,
available for disposal during the dry
season. Fourth-That an insufficient
of sewage would be accepted in
winter. These conclusions, together with
the experience obtained elsewhere
clearly show that there will be no diff
Guilty of disposing of the sewage on land
south of the city during the summer,
but that in winter no demand exists
therefor. The problem, therefore, requir.
ing solution is the finding of a prac.

age during the winter months.
"The estimates of cost are based upon
the requirements of frst.class work
throughout, and upon the demands of a
population of 200, 1000 people, and daily
amount Of sewage equal to 10000, 900
gallons, with maximum flow of &c..
600, 900 gallons. The excavation and
back filling together were figured at an
average cost Of fifty cents per cnbic yard,
and $25 were allowed for 1000 bricks
laid in strong mortar of English Port
land cement. The cast iron outfall into
the ocean is estimated to cost $50, 1000,
and $40, 900 was assumed to cover the
expenses for the purchase of rights OF
way and the necessary ocean frontage.
The outfall sewer should extend about
1000 feet from the shore into 35 feet of
water and consist of two pipes, each
three feet in diameter. These pipes
may be either laid on the bottom and
covered with rip-rap, or laid in trench
dredged five feet deep and covered with
sand in order to make them safe from
the action of waves. At the outlet the
pipe should be turned up and extended
ten feet above the bottom. 1t should be
protected by heavy rip-rap or concrete
masonry. For the present it should be

tended to. The screens, the machinery
for lifting them, the furnace and coal
shed, should be enclosed in one building
which is to be erected over the sewer
near the shore at an estimated cost o.

The report then considers three routes
to the ocean, taking first the river route
to Long Beach, estimated cost 81 ,035, 500
then the route via Centinela, estimated
cost $787, 400, and the last the Balloons
route, estimated cost 1896, IT'S, or about
$3.50, 900 more than it was estimated &c
cost when submitted to the people. The
cost of publication by land is estimated
according to location, at $735, 400, $685..
600 and $4,000. This includes the
purchase of 800 acres of sandy land and
the outfall sewer from the city to the
land. The cost OF chemical precipitation
is fixed at $491, 900 for the works and
outfall, with yearly expense of 500, 17z
if the location is near the river; $542, SOC
if the works are near Ballona, and $6S1 ).

The following conclusions were reached
by the board:
First. There is no legal authority te
pollute water course and to create anC
maintain q nuisance therein, and there
fore crude sewage cannot be discharged
into the Los Angeles river or any othe
available stream.
Second. For this reason it is no
within the province of the commission
to consider an outfall sewer to the
river, not far from the river, or to any
other water-course within reach, with
out making provision for the proper
publication of the sewage at the point o.
discharge.
Third. If the annual cost of purify
ing the sewage by precipitation is CAPT
talized and added to the cost of a shor
outfall sewer, the total expenses of any
such method of disposal in this locality
is far too expensive, and the commits
sion cannot recommend it.
Fourth. The filtration of sewage o
the winter months upon 800 acres o
land, either near the Los Angeles rive
or the Ballona creek is more expensive
than the cost of an outfall to the sea
but this difference is not sufficient,
great that it might not be balanced b,
other considerations than the question
of cost.
Fifth. The expense of taking care o
the sewage during the winter month
may be balanced by the receipts from
the crops raised during the summe
months, but this conclusion depend
greatly upon the skill, intelligence ant
int If tho ~, uonout
Sixth. The operation of filtration
oblige it to enter directly or indirectl,
into competitive business for the raisin,
and sale of crops, which is to be looked
upon with disfavor.
Seventh. The owners in severalty o
those large areas, which by reason o
their size can alone profitably receive tn
amount of sewage upon which the pres
emit estimate is based, refuse to enter int
any engagement to take this sewage
unless the city guarantees them agains
any loss resulting from litigation.
Eighth. The city can give this guaran
tee, or can guarantee the general publ
against the creation of q nuisance, onl,
when it is in position to dispose of tn,
sewage properly at all times.
Ninth. Other things being equal, al
outfall to the SEES, which requires mini
mum of care and attention on the part o
the municipality, is therefore to be pre-
ferred.
The outfall sewer to Long Beach alon,
the Los Angeles river is the most expen
sive among the sewers projected to til,
ocean.
Tenth. There are prospective objec
