air may be accomplished without creating
perceptible currents. Many methods have
been devised for the purpose of effec,iag
this end.
One of the best for large buildings is
that which provides nues connected with
the chimney The air in the tlues be-
comes warmed BY the h7, air which pass
es up with the smoke, aud having been
heated rises and leaves lis place TO be sup
piled with foul air from the top of the
room, which, IN turn, is succeeded by a
current Of fresh air, admitted at apertures
provided for the purpose a, the bottom of
the room. Some good reasons are given
for having the aperture for the escape of
the foul air at the BOTTOM of the room :;
but the case is still one which admits dis
cussion. Another method witch | have
never seen tried in a school house. though
il seems we'll suited 10 our common schools,
which are usually carried on in single
room, would be, to place ven,ila,or or
register in the centre Of the ceiling, and
to provide the ends Of the garret with lat
lice work. The air of the room when
sufficiently warm to be comfortable, would
pass through the ven;ilator and lattice TO
the external air, and thus constant cir
culation would readily be maintained
The rapidly with which the change would
be made could be increased or diminished,
by opening or closing the register.
That the rooms should be we'll lighted
is SO obviously necessary that il has been
overlooked in but few Instances, but equal
care has not always been taken ;ha. i, be
admitted to the room from the right direc-
tion. Il is generally agreed that it should
never be allowed 10 enter from that quar-
ter toward which the face is directed the
best directions from which 10 receive it
are from directly overhead and from be-
hind. As il is not always practicable to
admit sufficient from these quarters, side
windows must be tolerated, but the guam
tiiy and quality of the light admitted
should be regulated and modified by means
Of blinds or curtains.
The method by which the building is to
be warmed should be decided upon before
the plans are drawn. The kind of fuel
which will be used is in many instances
determined by the situation of the place,
Ill. =. - - ,oeo-. o.;,har ,,.ool or coal
may be used al abou; the same expense.
A thorough trial Of both, together with the
many opportunities which have been mine
for Observing the use of both in school
buildings, forces me unhesilatingly TO give
my voice IN favor of coal. That | have
used little of the biluminouS coal found in
these regions, Is. however, true. Among
otLer reasons for It's Use in reference TO
wood. these are by no means unimpor-
tant: a more even temperature can be
maintained by the use of coal-it requir,
very much less attention than woodland
and occasions much less dirt. These ad-
vantages would result when but one room
is to be warmed and stoves are preferred.
If, however, two or more rooms are used,
and a furnace or furnaces can be provid
ed, tie gain Is still greater. The tenn
perature would not only be uniform ,hro'-
out the common session room, but the DIFF
ferent recitation rooms may be easily
kept at the same temperature thing
scarcely attainabIe in any other way. If
there are those here who, in their school
going days, have been obliged to pass from
an over-heaied study room to an ice-coId
recitation room, or, as is perhaps more
Frequently the case. from recitation room
heated sweltering hot to very cold ses-
sion room, they can easily appreciate the
advantages of this system. 1t also avoids
the Inconvenience and annoyance of hav-
ing a s;ove in the room al all. Very
large school buildings are now frequently
warmed Nth steam, and there car be it,
lie doubt that this is the best arrangement
for such buildings
When, however, nothing more than
good sized village school is to be heated,
it seems to me this would be an excellent
arrangement. Il requires, in common
with other furnaces, lhat the house he pro-
,ided with & cellar, and, indeed, this
should be done in every house, whether
to he warmed by furnace or not. The
cellar can also be used as a wood d-house,
and for other like purposes. In some
point Of the cellar, so situated as to be but
a short distance from each of the rooms
above, build up a small room of masonry,
having walls at least equal TO the thick
ness of TWO bricks. |, may he four feet
square and six feet high. and should be
