GARBAGE CREMATOR AT LOWELL MASS
concerned The crematOry Is small low building near
Castle Williams. 1t built in 1885. and two years
ago the furnace was t0rD down ana larger one
built upon the original plan.
The Governors Island crematory was constructed
under the supervision Of Lieutenant H. l. keiiy' Oh
the United States Army. Formerly the garbage from
the barracks buried but the ground used Tor tat
ppose soon became saturated with the noxious gases
given out by the rotting filth, and In summer the
odors were unbcarablc The garbage dcstrucor which
Lieutenant Reilly designed Is the simplest knd OF
furnace without any special provision for the burning
OF the gases given off by combustion. II Is hrc-
brick chamber divided into three spaces by iron
grangs. The garbage Is supported by the cravings
which prevent from stopping the draft and puttng
out the fire. The garbage is shovcllcd through iron
doors in the upper part Of the furnace The fire
burns in the middle space. II Is started with WOOD
When the furnace is thoroughly heated no fuel Is
needed beyond the garbage which l. shaken through
the graiings. The tall chimney has powerful dfaus'
and the combustion IS almost perfect The SMOKE
escaping from the chimney Is at most times Scarcei!
perccptible. No offensive odofa can be de'eo'eu near
the crematOry, and even when the three furnace
doors are thrown wide open the smell resembles that
Of burning paper and Is not disagrecalle. AS no
special APPARATUS Is used for burning the gaseous
nroducts of combustion n small quantity OF gases
must find their way into the outer air. but 'hose
living on the island have never experienced any III
convenience. The services OF one man are required
a few hours day TO tend the furnace. The small
furnace used ly the Board OF Health at the Reception
Hospital In slxteenihst. for burning Infected co'Hhs
and bedding is constructed on more elaborate pm
ciples. II consumes the smoke ana gases ana iu

the gases given oil by burning garbage an inecho"
engineer has constructed a crematOr into which large
ouantItjes OF air are forced. The garbage Is irst
screened TO separate the bits OF metal broken dishes
ond stones from the vegetable and animal matter.
The organic materials transferred to The crying
ovens OF the furnace, which communicate dlrecty
with the combustion chamber. These drying cells ar"
so placed in the upper part Of the furnace that the
flames pass around them, consuming any hoXions
gases which may result from the desccation OF the
garbage In the lower part Of the drying cells are
outlet gates, which opened when the garbage j.
