I day we will wake to the fact that
it is economical of both time and
health to quickly and completely
change the air in a living room even
though it require the cessation of
present task for as much as fifteen
minutes every two or three hours.
Most assuredly this may not be done
at all times and under all circum-
stances of age, health and climate.
But most able bodied, vigorous indi-
viduals would be instantly refreshed
and permanently benefited by a wide
opening Of all windows for a few min
utes, the length OF time depending
upon the wind velocity and amount of
draft through the room, the outside
temperature, and upon the size of the
room and the number of persons
vitiating the air.
AS to the second condition, in re-
gard to temperature, it is very evil
dent in home life that there is a diff
ference in the requirements of an aged
person and one in youth. Further the
same active healthy adult requires a
different temperature at different
times and under different conditions
of bodily vigor.
Now we come to that fourth factor
or humidity. We must admit that the
vital problem has not been solved on
a basis Of the other factors alone. We
are inclined to prophesy a great future
resulting from research In this direc-
ton. This is based upon the expert
ments of others as set forth in the
literature of the subject, supplement-
ed by some investigation and expert
mentation by the writer. Sufficient
data has been collected to make 1t
clear that a very important factor for
health and one far from negligible
from the standpoint of economy in
house heating has beer discovered.
1t was recognized that the data
collected in this line OF work is very
must of necessity be done before any
final conclusion a be drawn. With
this in mind the speaker undertook
the direction OF research investigation
at the agricultural college, in his home,
and other buildings.
Az it is a fact that the Interpretation
of some of such data as is here ex-
hibited depends in some respects very
much upon the personal equation-the
feelings" and sense impression of the
observer, 1t was deemed advisable to
have several persons observe the con-
ditions and note the individual ef-
feet. More credit will attach to the
conclusions since there is agreement
Of opinion.
Original lines of research have been
followed out and the data now being
collected is intended TO show:
First, the effect of ventilation upon
room humidity.
Second, the relation between indoor
and outside humidity.
Third, the effect OF certain hunnidi-
aers upon the moisture content of the
house.
Fourth, Q h1rnidities in la) dry
climates, annual precipitation twenty
