MANUFACTURING HEAT.

because you do not now need 1t TO
keep you warm. You have put ny
screens in the windows and doors In
order that they may be thrown wide
open to permit a free circulation OF
air through the house Thus you may
avoid the heat and be comfortable
without letting disease bearing insect
pests in. You know that closed
room in summer is uncomforta Bile,
and you have heard perhaps that 1t Is
dangerous as we'll and you are guard
ing against that danger. But have you
reasoned out why it is so? Do you
know? Do other things about your
person prove and proclaim that you
have acted consistently and according
to known principles, or that you are
Just following conventional lines and
habit and have done this or that be-
cause others do it?
Perhaps you are also beginning to
ask yourself and your acquaintance,
too. the question that comes to the
mind of the vast majority with the
first hot days OF summer: What can
l drink to cool me OFF," Curious. Is it
not, that the old cure" idea jumps
out at us at every turn? 1t would ap-
pear that we think always that We
must take something" to correct un-
comfortable conditions, and it never
seems to occur to US that eminentiy
satisfactory results may be had from
within.
Without doubt you would think your
neighbor decidedly queer II. during
this hot weather, he were TO keep his
furnace fire going, close the windows
Of his house and buy Ice to cool him
self with.
Probably no single contribution to
the science Of nutrition has been pro-
ductive of knowledge capable Of more
profoundly influencing human life
than has the calorie idea. BY means
Of this unit of measurement food re-
Quirements become matter Of accu-
rate demonstration, and 1t is proved
that the transformations of chemical
energy into heat and work in the ami
NAL body take place according to the
same general laws as In our artificial
motors
II air is dry 1t more readily takes
up moisture and thereby cools US,
whereas If the humidity is high-that
is, II the air be close to its limit Of
water vapor saturation-of course
there will be but little room in it for
our moisture. For example: At 80
degrees Fahrenheit and so per cent
humidity the air will have a capacity
for IA grains Of water per cubic foot
and comparatively moderate volume
OF such air will keep our skins dry
and cool; but If the humidity be 80
per cent then there is room in 1t for
but 1.4S grains Of water per cubic
foot and we will heat and sweat on
the slightest exertion.
Very exhaustive tests in many parts
OF the world by various experts on
many subjects prove that the average
man. kept absolutely motionless and
fasting, develops 1925 Galleries per
day, an amount Of energy equal to lift
ing more than $500 tons one foot.
Note carefully that this is body tissue
combustion. Food necessary for sim
pie maintenance alone would increase
this fully $50 calories. II permitted
to move about the room the man
would require 1870 Galleries, the
equivalent of 3,434 foot tons. These
tests go to show 1t is very necessary
that we should adjust and balance our
food to our requirements and that
intuition and guessing are unsatisfac-
tory and unsafe methods for arriving
at sane solution OF the food ques-
ton.
1t would also seem to make clear
the absurdity Of attempting to "cool
OF" by pouring various wet goods
down our threats. The solution OF the
heat problem is: First, not to take
more food than is required easily to
accomplish our daily tasks. Second,
to clothe ourselves 80 as to permit our
radiator-the surface of the body. in
Guiding the scalp-to fulfill its func-
ton. Incidentally, cut down your meat
eating, unless you are laboring man
at hard labor.
Cut out the beer and the cocktail.
For lunch bowl Of bread and milk,
or large portion of dandelion green's
or spinach or asparagus with plenty
Of good olive oil and lemon Juice, and
some bread and butter, will keep the
machine running until we get time to
consider fully the food question.
Dandelions and spinach are rich in
iron and other mineral matter and
this Is the season to catch up on your
