A Recommendation That It Be Built by
tho Boston Bidders.

that contract be made with the Amerl-
can Garbage Crematoir Company of
Boston for Brown patent crematory.
The recommendation is in the shape /
of a resolution and will be presented
to City Council this evening,
when the contract will probably be
awarded. A site for the crematory has
been selected, but it is deemed best to |
not announce its location until after the |
negotiations for its purchase have been
completed. Work on the crematory |
will begin Immediately after the con-
tracing company has furnished bond,
and is expected to be finished in six
weeks, about the last of September,
during the season for preserving fruit,
when the quantity Of garbage is greatest.
! The American Garbage Cfematoir
| Company agrees to erect o crematory
here for $4,000. 1t thinks thatthe cost
for destroying garbage may be as low
as 20 cents per ton, and guarantees that
it will not exceed DO cents.
The Brown crematory OF standard
size is 43 feet in length, with an inside
width across the CRATE of o. feet. 1t
stands about 0 feet high. It is con-
structed with thick walls of fire-brick.
| This friedrich, Furthermore, is glazed
on its inner surface with boracic acid
preparation which protects the brick
from the action of all aqueous gases
and keeps it from disintegrating under
the influence of the great heat. Sur
rounding the furnace on the outside is
water jacket, in which water is kept
constantly moving. This preserves the
exterior of the furnace at an even tenn
perature; it keeps the brick annealed
and greatly retards any tendency to
disintegration. II is well-known fact
that furnaces supplied with this water
jacket have been known to endure in
active service for 20 years, while similar
furnaces not thus protected have been
burned out after four or five years of
service. In workmanship and material
the Brown furnace is of the very best
and is fully guaranteed.
AT one end of the furnace, near the
top, is situated the combustion chamber,
into which enters the burner. This
burner not only conveys the fuel to the
combustion chamber, but as a matter of
fact forms the fuel, being not only q
burner but gas generator This burner,
or generator, as it may inter-
changeably be called, consists Of
cylinder composed of three

these pipes contains steam, the second
pipe crude petroleum, while the third
contains burnt gases, which have been
drawn out from the combustion cham
Der itself and which are now returned
to it. These three pipes, emptying their
contents at the same time, have this
effect: the steam CASTLES the oil and
this gas in turn mingles with the gases

! the highest combustibility. This is
ignited as it enters the combustion
chamber. II is subjected to three trans.
, verse currents of superheated air, one
entering from either side and one from
: the back of the chamber. Then, in q
state of high combustion, it is driven
bv blast over the bridge that separates
/ the combustion chamber from the CRATE
and is sent with great force and volume
!. over the mass Of garbage. Then this
q voluminous fame, intensely heated and
charged with oxygen, turns and passes
: back again under the CRATE, attacking
the garbage on its under surface and
!. thence goes through the flue into the
i. smoke-stack. 1t will be perceived that
q the combustion fame traverses the gar
h bage twice--first over its entire upper
/ surface and then underneath. AS the
q CRATE surface, on which the garbage re-
n poses, in the standard furnace which
y consumes five tons an hour, is about 4C
Il feet in length, it will be perceived that

n absolute and complete combustion.
The CRATE is so important feature o.
the Brown crematory brief descrip
ton of it may with advantage be given
$ AS previously stated it is nearly 40 fee
le in length. A supporting wall, situated
Is under the middle of thegrate, runs from

: matories are wont to make boast of tn
y fact that their CRATES are composed 0
- fire. brick and that this is virtually indie
"a structible. The Brown crematory, afte
many experiments, long since discarded
friedrich for the construction of th
tie CRATE, for the reason that friedrich is

re more, the action of the sodium in th
H. garbage is such as to vitrify the surfac
IT'S of the brick, rendering it still more
It non.conductor. The result of this
Is, that, where the garbage comes in cor
