RESERVE WATER SUPPLY.

u
Robert Morrow Jr. made his report
relative to a water system for the pro-
lection of the city. One suggestion he
made was d scheme proposing reser-
voir on the hills, which was con-
demned; another method, that of a tun-
mel under the bay to supply the en-
gines, was deemed good, but too ex-
pensive; and the third suggestion was
the establishment of a series of pump
ing stations driven by electricity, with
gas auxiliary. This proposition Nor
row said, was the least expensive
NJ. NJ O'Shaughnessy, civil engineer,
said:
This is matter for solution by q
board of expert engineers who will
thoroughly consider all phases of tho
proposition of salt water protection for
solve the problem.
likely one might be the construc-
tion OF an aqueduct, say ten feet be-
low the sea level in the solid rock for
nation across the city. This would
be constantly filled with water which
could be drawn from 1t at various sta
tions and make an impregnabIe bar
rier to fire across the city and avert
repetition of the recent eonfagra-
tion.
An auxiliary pipe system in connec-
tion with this as well as reservoirs on
the adjacent hills are subjects for con-
sideration, and for this reason / recon-
mend your organization to retain a
board OF specialists 10 advise with you
on this subject.
The probable cost would be $500. 900
for the main conduit of about three
miles length.
l think that the proposition for a
salt water reservoir on top of Twin
Peaks for fire protection at the present
time is ill-advised, as 1t is about three
and owing to its high altitude. 700
feet the pressure on the pipes would be
about 2S0. pounds TO the inch. which
AS to the possibility of wells be-
meath private property it is possible
to have a limited protection in each
building from this source. but it would

100000 gallons in twenty four hours
at one point, which would be too small
Understand that John center's
small pumping plant and 10000 gal
lon water tank saved the spreading of
the fire in a southeasterly direction
in the neighborhood of Twentieth and
Folsom streets.
1t was resolved to appoint two other
expert engineers with 'Shaughnessy
to devise a system of salt water sup
ply with recommendations, which will
be submitted to the Supervisors.
STATES MARBLE THE BEST.
Joseph Scheerer appeared before the
association to advise matters of ma
terial for rebuilding and proved a
powerful champion for California mar
ble, which he advised in the recon-
struction of the city. Sheerer said Cali
fornia has enough marble to build te
New York and back again" and he ad-
vocated its use because of its superb
ority over any other marble ever
brought here.
He held that Italian marble is soft,
as is that from Vermont which he ad-
mitted looks exceedingly well but will
not stand the fire or water test. He
invited the association to appoint a
commission to visit San Bernardino
County and judge for itself, and as a
proof nearer home he referred the asso-
citation to examine the California mar
BILE used by DIR. Herbert Law and his
brother in their Monadnock, Rialto and
Crossley buildings.
He declared that California marble is
crystallized and contains so per cent
of carbonic acid gas, which repeIs< hea t.
Sheerer was requested to occupy the
associations attention with the virtues
of some other materials. He retorted
that that is just what Is the matter
with so many-they do not want to
listen to an explanation of that which
might help them" and with a courteous
bow and in spite of appeals to continue
he withdrew.
H L. welch expressed his wish to
see the grades changed on Rincon HILL
which he contended would benefit the
whole city. The hill is centrally To-
Gated and a heavy business is done in
It's vicinity He would like to see II
icut down and the material used In
