GOODNESS IN SUMNER.
REGULATING THE TEMPERATURE OF
DWELLING HOUSES
VARIOUS ENrEDIENTs. ACTUAL AND POSSIBLE
WILL LIQUID AIR SERVE?

Entirely new methods of cooling the atmos<
phere OF dwelling bouses and places of business
IN summer are likely 10 be devised in the future.
And it is strange that greater headway has not
already been made in that direction Certainly
there is room for great Improvement upon exist
ing facilities-ventlation, tanning and the
artificial reduction Of temperature. Neverthe-
less, II IS doubtful whether even these are util-
lied as inteIligently and fully as they might be.
This is particularly true in regard to ventila-
ton at night. a large number perhaps the
great majority, Of the places of residence in this
city, face either to the north south In the
summer time, and especially during the preva-
lence of extremely weather, whatever
breeze there is comes from the south or south
west. This may be light but if it has a fair
chance it viii afford apprecable refreshment to
the inmates of a house at night If the windows
looking TO ths southwark are wide open, but
the doors connecting with the interior are closed
little or no benefit Will lie derived or. if these
windows and the doors Of the south rooms are
open but the doors Of the north rooms are shut,
the necessary ventilation viii not be secured. II,
however, the way be opened for a draught clear
through the house from south north a much
larger volume Of outside air win enter than
would otherwise be possible, and in Instances
the mercury would fail several degrees. Yet
TO recognize this principle.
Electric fans have come into extensive use in
the last two or three years but their possibilities
are not fully realized. These devices create a
vigorous breeze in their immediate vicinity.
Such zenhyrs, like those produced Ly riding in
a trolley or excursion steamboat. yield
perceptible results. They cause rapid eVap-
orauon Ct moisture from the skin. and thus re
duce its temperature. When there Is much hu-
miGity in the air the difference Will scarcely ex-
ceed + or degrees, but every little counts"
during a hot wave.
But the great advances TO be- made in the art
Of keeping cool viii unquestionahly come from
The OF some such refIigerating apparatus As
: now employed in cold storage ware houses.
In these a temperature Of about - degrees
Fahrenheit is maintained day after day anG

would require only q slight mobilization # the
steam and hot water radiators now employed in
hotels and dwelling houses for heating purposes
to convert them into coolers. Brine or other
fluids from which the heat has been abstracted
in the basement could be forced through them
and TIE occupant of room could regulate the
chilliress Of his surroundings by turning tn.
valves in ore direction or the ether.
Another way to deal with the question is that
already in the St. Nicholas Rink There.
nearly two feet below the floor is a sheet OF ice
over its surface air from outside is drawn.
This is then driven into the auditorium
by TWO powerful rotary fans. BY varying the
speed of the latter, a greater or less effect is
produced on the temperature Usually the ther-
