What to Eat and Wear In Hot
Weather Scientifically Ex-
planned by These New
Investigations

government at Aldershot show that heat
Is thus absorbed most by black textures,
next by pink and then by the other colors
In the following order-yellow, gray and
white. Hence outer day clothing to reflect
the most heat from the body should be
white.
Women in the selection of their summer
dresses will find gray materials next to
white In GOODNESS. and yellow materials
cooler than pink. But even white clothing
while rejecting the heat rays freely ad-
m1tS the light weaveS. so dangerous to the
nervous system of white men, and which.
according to Maj. Woodruff, are responsible
for many of the skin diseases of bionds.
Therefore we should wear the black under
clothing In connection with the white outer
clothing. We then are equipped with
double shell OF armor piate-the outer white
layer protecting us from the bomba rdment
Of heat rays and the inner black layer pro-
tecfing us from the assault of the equally
dangerous violet and ultra violet rays which
have sifted through the white after the heat
rays have been excluded. This combination
initiates certain tropical animals which
have white hair and black skins. "A black
negro dressed in white is about as happy
and contented a being as we have in the
Philippines" says the major The Moors of
the north coast In Africa also know the ben
efts of the combination: for they wear
white robes almost exclusively Yellow Is
second to black In power to stave off these
nerve-racking rays. So for those who
shrink from the idea Of black summer un-
answer almost as we'll.
For summer evenings black outerclothng
as well as underclothing is best, IT al
lows the readiest escape Of the heat radiat-
ing Off from the body. For this reason noe
turnal animals are black After the sun
has gone down this question of radiation is
the only one to be dealt with, all coors
absorb the dark rays equally.
For persons remaining indoors black or
dark blue Is for this reason cool In summer.
But In the sunlight blue becomes very
warm. Blue reduces light rays to heat
rays
Line Your Hat With Tinfoil.
AS to headgear a white hat with an inner
lining Of tinfoil is recommended by DR..
Woodruff. The white exterior reflects the
heat rays. as In the case Of the other gar
ments. and the tinfoil shuts out the danger
Gus violet and ultra violet rays even better
than black material. He does not. however,
recommend tin underwear, which reminds
us that some one else did. but for what pur
pose we cannot now recollect.
In summer the skull must be protected
from these deeply penetrating ultra violet
rays, which pass entirely through the skull
as we'll as the scalp. Even a few minutes
exposure bareheaded to the tropic rays is
known to have been fatal In India The
hair Of natives of tropical countries Is pro-
| fuse and black. which Is hint to us that
we should wear our locks long in tropical
weather. even If nature has not dyed them
black. Scalp diseases, according to DR..
| Woodruff. result from shingllng hair which
men run even greater risks than those
blessed with hirsute adornment and should
doubly fortify their hats.
