PROBLEMS IN COLORS
WHITE IS COOL, YET ARCTIC ANIMALS
AS A RULE ARE WHITE.

In summer weather ladies'. and men,
too, when possible wear white. Why?
To keep cool, Of course you will say.
IL this be so. why. then, are almost all
the creatures that live In arctic regions
clothed In white? The usual reply Is
that the white. color Is for protective
purposes--in order, In fact, to make
them invisible to their enemies in the
midst of the wastes OF snow.
But consider, again. is this reasona-
BILE? From whom does the polar bear
need to hide? He has no enemies to
fear. And as for the birds which as
sumo white plumage when they mi
CRATE north. surely they also have far
fewer foes In the polar regions than
when farther south.
Again, IL white be a cool color this Is
surely another reason against the in
habitants of the coolest regions turning
white at me approach Of winter. It is
easy to strengthen this argument Visit
the tropics. and you will find hardly
any white animals or birds. In the very
hottest regions of the globe not only is
man, as a rule, black. but the birds and
ben sts are either very dark or else ex-
tremely brilliant In color. OF tropical
birds the commonest colors run as fol-
lows: Brown, dark green and dark blue.
emerald green. reds and yellows.
Speaking of the birds again. why Is It
that land birds are mostly dark hued
while 50 msay sea birds are white?
Here Ia another color puzzle. Almost
all song birds are somber in hue, while
the brightly colored apecies, such as the
| jays, the parrots and birds of paradise,
have .natErally harsh voices.
| The colors OF flowers and leaves offer
numbers of interesting problems. No
one quite knows why the prevailing
tint OF early spring flowers is either
white or yellow. Yellow, indeed, holds
its own to some extent all through the
summer, but the typical color OF sum-
mer blooms Is pink, while as the au-
tumn advances richer crimsons and all
the rich. glowing hues Of dahlias and
chrysanthemums are seen.
Horticulturists have produced pop
pies Of pretty nearly every shade under
the sun, and with many other flowers
they seem able to alter the colors al.
most as they please. Yet the blue rose,
the black tulip and the green carnation
seem as far of as ever they were In
spite OF constant efforts to arrive at
them. Nearly three centuries ago
Dutch gardeners imagined themselves
on the verge of inventing black tulip
The colors of the blossom Of fruit
trees are limited to white, pink. bright
scarlet and purple. The reason no one
knows. Nor is 1t clear why nearly al
plants with purple blossoms have poi
sonous properties mo deadly night

imagine that intensity of color depends
upon intensity of light The brilliancy
OF tro"Ical landscape seems In some
measure to bear this out. But any
amount of arguments may be deduceC

exquisltely colored gems are dug from

The rays of the sun have never
touched them. The pulp of some fruits
is more richly tinted than the outel
rind, while the crimson blood Of ant

Yet these are all night flying creatures
Speaking of moths, 1t seems odd that
there is no blue moth. Very few show
even Il touch or spot OF blue. The col

strange point is the absolute difference

Why do autumn leaves turn yellow
Here Is question which is more eas
lily answered than some that have al
ready been suggested. The popular
reply is, "The frost does It," This Is
only partly correct If really hard
frost were to happen early in autumn
there would be no tints at all. All the
leaves would turn brown at once. The
really gorgeous colors are produced by
slow and gradual fall OF temperature
Of course, without too much wind OF
rain. The cold causes chemical fer
ment, which attacks the color com
pounds in the cells of the leaf. 1t is
. those leaves which contain most sugar
which oxidize most rapidly and OF
. which, consequently, the color becomes
most rich and brilliant.
A question which Is often asked Is
, ''Why do Holsters, shrimps and certain
other similar shelfish turn red when
boiled? 1t seems that the black color
ing matter which colors the shell Of the
lobster during life is an iron com
pound. We know that iron rust is red
The effect OF boiling Is practically to
turn this iron compound in the lobster
shell to highly oxidized rust.
The dislike of certain creatures for
certain colors is strange. II number

red and the other with blue glass. they
