| ing the last winter, and the whole top oi
the slope ON which the derricks had
rested had been dragged into the sea by
the waves.
A SANDSTONE QUARRY.
l have examined a quarry OF sand
stone on the line of the Southern Pacific
railroad. about fifty miles from Port
Los Angeles where there is an unlimited
supply Of suitable rock, with no strip-
ping, for the base of the work. This
rock weighs, from specimens obtained,
$50 pounds per cubic foot. The ledges
lie within one mile of the end of the
track of the Chatsworth branch and
conveniently situated for large num-
Der of tracks, nearly half q mile in
length along two faces OF the bluff. 1t
is a down grade nearly all the way to
the harbor. Five trains of thirty 20ston
cars could easily be handled from this
Port Los Angeles.
A GRANITE QUARRY.
have examined a quarry of first
class granite at Declez, near Cotton and
near the main line of the Southern
Pacific road, east of Los Angeles. This
stone weighs about It's pounds per
cubic foot. 1t is very hard. tough,
compact, uniform, durable rock, pure
granite and entirely suitable for any
part of the worb.
The buttes OF nearly bare rock rise out
of the plain to height of 800 to 400 feet.
Tns quarry could be worked ON two
faces, each about ons-fourth mile in
length.
There 10 estimated to be in the quarry
under consideration, and controlled by
the Southern Pacific company, about
5000, ,000, 600 cubic yards Of rock. be-
lieve five trains Of 20 Cotton cars each
could be handled and hauled from this
quarry, making total output from this
and the Chatsworth quarry OF 5000 tons
per day.
GUARANTEE ON ROYALTY.
l may state here that l have guar
antee from the railroad company that
the royalty on the rock in the DscIez
quarry shall not exceed 1211s cents per
cubic yard, and the statement that it
will probably be nothing at the Chats
worth quarry, and shall not in any event
exceed l211a cents; also that the rate for
hauling the rock from either quarry to
Port Los Angeles shall not exceed one
half of l per cent per mile, which will
scarcely cover the coat of 80 short q
haul.
The grades on which the Dsclez rock
would be hauled are also easy, though
somewhat heavier than from Chats
worth. For this reason l have estimated
20 as the number of cars in q train from
Declez.
II the stone comes from either OF the
land quarries above described, the con-
structIon OF q pile bridge or trestle will
be necessary in order to reach the loca-
tion of the breakwater. This may pos
sibly be considered objectionable, but
believe. from my own experience, it is
entirely practicable and
THE PROPER WAY
to construct this work. At tho mouth
of the Mississippi the work was carried
on by floating equipment entirely. and
was often delayed by the weather. At
Tampico, in designing the works, pro-
posed the method OF carrying the stone
by don ble-tracS railroad on trestle-
work. The mattress work also was built
from this work. The north jstty is 1000
feet long, exposed nearly its entire
length TO the hsaug aeAs f-e..e e...iss aH sr-Ine
gulf of Mexico with great force. While
the piles were not driven in over % feet
OF water, not as deep as at Port Los An
geles, yet the exposure was much greater.
The work was conducted for over two
years by this method with very little
loss. The great advantage was that the
work was tied to the shore by railroad
tracks, and from there to the quarry,
situated rs miles distant. l believe. from
the experience gained there, that it
would be entirely practicable to con-
struct the work as rapidly aB desired.
We found it practicable to haul 100 cars
OF rock per day out of one quarry, with
only one face. over a rough road with
undulating grades and with compare
lively very inferior rolling stock.
OF UNTREATED PILES.
From all that can learn OF the action
Of the teredo In these waters, I think
untreated piles would last from.three to
four years, which would be sufficient
time for completing the work. However.
for absolute safety, | would recommend
to oreosote all piles that would need to
be exposed over two years. l see no
reason, however, why all of the rock
should come from these land qusrries.
and would suggest that as much Of it as
possible should be taken from the quarry
at Catalina leland for the base of the
work, but that the main dependence
should be placed upon the supply from
the land quarries. Considering the dis
advantage and expense and delay by re-
living entirely upon the Catalina stone,
believe the work can bs done more
cheaply, more rapidly and in every way
more satisfactorily by taking larger
part of the stone from the quarries on
land.
There are other considerations OF more
or less weight in favor Of Santa Monica.
CONSIDERATIONS FAvoRING SANTA MONICA.
The city OF Los Angeles is quite
rapidly growing in that direction, for the
reason that the land is better adapted for
urban groth. 1t is level, with gentle
slope seaward. Electric roads, good
streets and good roads will soon exist the
entire distance. The country toward
San Pedro is much different, more broken
and less desirable for either farms. roads
or streets. The distance in q straight line
between Los Angeles and Santa Monica
is l211 miles, whereas San Pedro ia dis.
tant 1874 miles.
The above may at first appear to be an
unimportant matter, but when it is con-
sidered that, whatever point is selected,
it must necessarily be the port OF the
city OF Los Angeles, the comparative
nearness has much to do with the ques-
ton OF selection. Los Angeles is sure to
be the great central distributing point
for the entire country in this latitude,
