of its refuse by shipping it to the Ha-
waiian Islands to be used as fertilizer.
a Los Angeles agent brought f0rwa rd a
project of building and operating crema-
tory similar to the one now used at Los
Angeles.
The Varney boat method was also con-
sidered.
But the most feasible, efficient and
economic plan, and the one that will in all
probability be adopted by the Board of
Health, which has the matter in charge, is
that the city build its own crematory and
run it as a regular department.
A crematory, which is now in successful
operation in more than forty cities of the
United States. will be the one selected. 1t
is inexpensive in the matter of its con-
structiOn and is superior 10 all others in
that the garbage passes through two fires
in the same furnace; the gas and smoke
from the first fire where the original CON-
bustion takes place being subjected TO
second fire in which the imuerfect CON-
bustion is made complete, and the smoke
passes out of the smokeStack, white. odor-
less and notfensiye and invisible most of
the time.
An ordinance will be passed at the meet
Ing OF the Council tonight appropriating
$1,000 for the erection of such a acrematory,
and $4,000 for the purchase OF site.
Three Indispensable requirements are
attained in the construction of the pro-
posed crematOry.
First. an adequate heat for the I'M
mediate combustion of animal and vege-
table garbage IN large masses.
Second, arrangements securing perfect
destruction by combustion of all gases
and Odors within the walls of the furnace.
Third. a construction sufficiently solid
and fre-proOf TO stand the enormous heat
required to accomplish the first two OBJ
jects.
y primary heat is secured by powerful
draught from a chimney or smok eStack rs
to 100 feet high, drawing through a for
ward and return flue OF % TO 80 feet in
length each way. or 60 feet in all.
The forward fue constitutes the cremat-
ing oven. It's dimensions are 5h by so
feet in cross section, which is sufficient
TO receive twenty cubic yards of garbage
and five barrels of liquid at one charge
Its bottom is friedrich grating, separat-
ing it from the return flue. which is i'm
mediately beneath it.
The garbage is dumped on iron slopes
leading down to the manhOles on TOP of the
furnace. There are four of these feeding
holes, one being large enough to take In
carcass of horse or cow. The covers to
the holes are round slabs Of firscIav.
The garbage Is sucked by a rushing
draUght through the mani holes and falls into
the oven fue on grate-bars made of solid
blocks OF fireclay. At one time steel rails
were employed in the construction of the
grating. but they constantly gave away
under the intense heat.
The startng-hre is at the chimney end.
and first passes through and over the mass
of garbage to the other extremity. where
a second fire, at the mouth of the return
hue. strikes the current of thick gases and
the force of both draughts Is united Ipiets
OF air at proper intervals increase the in
tensIty OF combustion, which is thus made
perfect. and all carbon and odors of
the burning refuse are destroyed. Mois-
ture only tends to intensity the violent
combustion. Every gaseous particle is
thus consumed and the heat is conducted
back toward the chimney underneath the
CRATES. intensely heating the garbage on
its under side.
The temperature of the two com bnstion
cham bers can be regulated TO any required
degree OF heat. The inside walls and roof
are large freclay blocks, Weighing sixty
pounds each. the outside walls being hard
RED brick, with heavy buckstays, angle
irons and trust bars, all strongly bound
and braced together.
There Is provided an upper range of
doors, through which the mass of garbage
is distributed over the CRATES and stirred
up, to allow the fire TO reach each particle.
Through lower series of doors the ashes
are Withdrawn from time to time.
The action Is continuous, and when re-
qured may be carried on without cessa-
tnn for months together.
When once this device is in smooth
running order Oakland will be provided
with one of the most complete inventions
for the disposition of garbage known to
scen tifc sanitation. It's operation will
be attended with but a nominal expense
The liquid and solid organic matter de-
strOyed furnishes the greater part of the
heat and reduces the outlay for fuel ma
terially.
The phosphoric acid and potash in the
ashes render them of consderabl COM
mercial value as fertilizers, and S25 per
ton can be realized from their SALE 1t is
estimated that per cent OF the garbage is
thus negotiable in the shape OF ashes.
saving from scaVenger hire will be
realized by each family in the city, for it
