WARMTH AND PURE AIR.
The Ruttan System of Heating and
yentilatlHg she Central school Build
ing-A Test Made This Morning.
At ten o'clock this forenoon q test was
made of the heating apparatus within
the new central school building. The
board OF education and many oitizens
we're present by invitation. The Ruttan
system is employed, and 1t is o venti-
lating as we'll as q heating system. The
aim of the system ia to maintain uni
form temperature throughout a building
and at the same time supply constantly
renewed atmosphere to those who occu-
py its apartments. II is @ system re-
sulting from q combination Of we'll ma.
tured scientific and mechanical princi.
Piles, confirmed In their utility by the
test of time and practical application.
In its workings it seems to fully realize
the promise of its projectors. A series of
furnaces is placed in the basement and
each furnace is provided with o cold air
corridor opening into the out door at-
mosphere. Through these corridors
| virgin prairie air is conveyed and IL pas
SEES in contact with the rsdiating surfaces
OF the tubular furnaces, warming it TO 9
comfortable degree and lifting it by its
own expansive force to the apartments
above. It enters these apartments
through registers located midway be.
tween the floor aud she ceiling and after
lingering Q few moments finds exit
through registers in the base boesds and
diffuses itself underneath the floors be-
fore finally passing into the escape flues
and mounting through the enormous
chimneys to be r~e.vitalized in the upper
atmosphere. In each apartment is I'D
iron crank placed over an iron dial, the
crank handle being held wherever it is
placed by q ratchet spring. BY turaing
this crank to the right or the left the
supply OF warm OK cold air is regulated
and the combination Of the two can be
SO nicely adjusted that the man or the
woman at the crank CAD hold the ther.
mometrical indicator at any desired de-
gree mark, regardless OF out door
weather conditions. This crank con-
neots, by means OF q chain. with fue
gates below. which are opened or closed
at the pleasure of the operator. 1t is
intended by this process of heating and
ventilating that the atmosphere of each
school room will be renewed once in five
minutes without o~hanging the tempera.
ture and a uniform heat diff used through.
out the building.
In the central school system there are
FIVE furnaces. each possessing the va
rious attachment above described. In
the test of this mornIng only light fires
were employed, iuGt sufficient to dem
onstrase the principle upon which the
system works. The test was In every
way satisfactory and the savants and
citizens there assembled declared unan-
imously in 7avor OF q perfect result. Al
the seyerest available test of %ven!ilatine
properties, the expert present closed the
doors OF one of the school rooms and
filled the room with sulphur fumes unit

Through the ventilatinR registers the

ed from the atmosphere within ffseer
minutes.
Another feature Of the system Is III
dry closets, which take the place Of
water closets, and their perfect utilit.
is demonstrated. The last use TO whicl
the heated foul atmosphere from tn
school apartments is put is in deodorl
zing these closets. Small furnaces or
provided for ventilating and purifying
