1 have made some quite careful exam
nations to determine the

Inc works, with the following result:
At Catalina Island, about thirty-fve
miles from Port Los Angeles, there is
quarry OF fairly good rock of volcanic
nature. 1t has been used for several
years on the Government works at Will
mlngton Harbor and elsewhere, and while
there Is, from appearances, some rock
there that Is not strong and durable, the
mass of it can, think, be relied upon.
This rock weighs about l45 pounds per
cubic foot, which is the heaviest of the
four specimens which | obtained by per-
sonal examination. 1t might possibly
answer for the exposed work, but would
De better adapted for the base. Unfor-
tunateiy there has been found but
one quarry of suitable rock on this island
and this is restricted in several ways. It's
total length is not over 500 feet; it is an
almost vertical bluff against very deep
water; the bluff Is about 800 feet to 400
ieet high and the water is evidently fully
as deep; 1t is sheer precipice, partly
above and partly below the water.
There is no room for handling more
than one or two barges at time, and it is
therefore entirely inadequate to supply so
large work as the proposed break water;
IN 1act, the comparatively unimportant
work at Wilmington harbor was, | am
told, delayed, and the time for completion
extended on account OF the inpracti-
caolIlty OF getting rock as rapidly as the
contract required. AS far as | could
ascertain, it would be very risky business
TO attempt to barge stone from this quarry
during the winter months, say from No
VemDer to April, when the seas from the
northerly winds are very heavy against
this shore. From the indications along
the face of the quarry, the waves, or their
spray, had reached the hight of fifty or
sixty feet during the last winter, and the
whole toe of the slope on which the der
rlcks had rested had been dragged into
the sea by the waves.
SANDSTONE QUARRY.
have examined quarry of sandstone
on the line of the Southern Pacific Rail
road, 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, 100
pounds per cubic foot. The lodges lie
within one mile of the end of the track of
the CnatsWorth branch and conveniently
situated for large number OF tracks,
nearly half 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 ZO-ton cars could easily
dumped into the sea at Port Los Angeles.
a GRANITE QUARRY.
/ have examined quarry OF first-class
granite al Declez, near Cotton and near
the main line of the Southern Pacific
road, east OF Los Angeles. This stone
weighs about 10 pounds per cubic foot
1t is very hard. tough, compact, uniform,
durable rock, pure granite, and entirely
suitable for any part OF the work.
The buttes OF nearly bare rock rise out
OF the plain To height OF 800 TO 400 feet.
Inc quarry could be worked on two
faces, each about One-fourth mile in
length,
There is estimated to be in the quarry
under consideration, and controlled by
the Southern Pacific Company, about
b,OO0,0 600 cubic yards OF rock, | believe
hVe trains of twenty 20-ton cars each
could be handled and hauled from this
quarry, making total output from this
and the Chatsworth quarry OF about 5000
tons per day.
GUARANTEE ON ROYALTY.
/ may state here that l have a
guarantee from the railroad company
that the royalty on the rock in the Declez
quarry shall not exceed III cents per
cubic yard, and the statement that il will
probably be nothing at the Chatsworth
quarry, and shall not in any event ex-
ceed l24 cents; also that the rate for haul
lng the rock from either quarry to Port
Los Angeles shall not exceed one halt
cent per ton per mile, which will scarcely
cover the cost III so short haul.
hC x dltS Ou WHICH the D0Cl6Z rock
would be hauled are also easy, though
somewhat heavier than from Chatsworth.
L or this reason / have estimated twenty
as the number of cars in a train from
Declez.
If the stone comes from either of the
lanu quarrleS above described, the con-
structlon of pile bridge or trestle will
be necessary in order to reach the loca-
tlon OF the breakwater. This may possi-
ply be considered Objectionable, but I
DelleVe, from my own experience it is
entirely practicable and
THE PROPER WAY
To construct this work. At the mouth of
the Mississippi the work was carried on
by a floating equipment entirely, and
was ofLen delayed by the weather. AT
Iamplco, in designing the works, pro-
posed the method of carrying the stone
by a double-track railroad on trestle-
work. The mattress work also was built
from this work. The north ietty is 1000
feet long, exposed nearly its entire length
to the heavy seas from the severe north
ers which strike that coast of the Gulf of
Mexico with great force. While the piles
were not driven in over twenty-eipht
feet of water, not as deep as at Port Los
Angeles. yet the exposure was much
greater. The work was conducted for
over two years by this method with yery
little loss. The great advantage was that
the work was tied to the shore by rail-
road tracks and from there to the quarry,
situated seventy-nve miles distant. l be-
HeVe, from the experience gained there,
that 1t would be entirely practicable to
construct the work as rapidly as desired.
We found it practicable to haul 100 cars of
rock per day out OF one quarry, with only
one face. over rough road with undu-
iatlng grades and with comparatively
very inferior rolling stock.
OF UNTREATED PILES.
From all that can learn of the action
of the teredo in these waters, 1 think un-
treated piles would last from three to
four years, which would be sufficient
time for completing the work. However.
for absolute safely, | would recommend
to creosote 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 quarries, and
would suggest that as much of it as pos
sible should be taken from the quarry at
Catalina Island for the base of the work.
but that the main dependence should be
placed upon the supply from the land
quarries Considering the disadvantage
and expense and delay by relying en-
tirely upon the Catalina stone, / believe
the work can be 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 MO-
MICA.
The city of Los Angeles is quite rap
idly growing in that direction, for the
reason that the land is better adapted for
urban growth. 1t is level, with a gentle
slope seawards. Electric roads, good
streets and good roads will soon exist the
entire distance. The country toward San
