within a limited distance somewhat in

aiid so affecting the balance of the forces
that determine our weather. But thiB Is
Entirely wrong. Volcanoes produce not
hot weather, but cold. The fires which
they give forth do nothing whatever, but
the dust and ashes that they throw out
do a great deal.
A tremendous eruption of Mount Erebus,
near the South Pole, could, and at least
once has, given us an approximation of the
g'acial age in a cold-killing Winter and a
cold Summer in which little vegetation
could develop and ripen.
How could this come about?
The temperature of the earth is deter
mined wholly by the amount of radiant
energy it receives from the sun. This
energy, in the form of light rays, passes
through the space between us and our
luminary without any effects of heat. But
our earth is surrounded by a .gaseous en-,
velope which we call the atmosphere.
When he rays of the sun pass through the
atmosphere and fall upon the earth's sur
face their energy is released in the form
of heat Almost all the heat in our atmos
phere comes from the radiation of sun
rays from earth's surface.
The sun delivers then every day a cer
tain quantity of heat ray3 through the at
mospheric envelope of our earth. If tho
skies be clear about half of this heat
speaking very roughly reaches the surface
of the world. The other rays have been
turned back by minute particles of dust
and by particles of watery vapor. If there
arc clouds, why then these masses inter
rupt the passage of more rays.
N'ow we know that we can shield our
selves from the sun's heat by parasols, or
umbrellas, or wide-brimmed hats, or awn
i.igs. and so on We know that these
shields keep us cooler than we would be
v ithout them. What we do with the para
sols, umbrellas and so on lt to turn back
te sun's rays from directly striking us.
What the volcwiop do is exactly the
j-anie thiliK!

lietween the sun and us a cosmic umbrella.
The sun rays are deflected by the count
less particles back into space, and every
wi.e so turned back means one unit of heat
io-.t to us. The dust thrown up by the tre
mendous eruptions is known to have risen
as high as fifty miles. The grains are so
minute that gravitation has very little
effect upon them and they may, and often
do, require years to fall back to earth's
surface. In the meantime they are taken
by the winds and strewn throughout the

part of it remains unaffected.
In 19X2 there occurred on the Alas
kan Peninsula one of" the greatest
volcanic outbursts on record, Mount

hours at Kodiak, 100 miles away. Sul
phurous fumes were dlstinguished-

the burning mountain. Dust fell at
Juneau and in the Yukon Valley, fif

were four and a half feet deep. All
vegetation was annihilated, and
bears, rabbits, caribou and other animals
went blind.
If the Weather Bureau had known then
what It knows now. It could have predicted
a year at least of exceptionally cold
weather to follow. The eruption occurred
Jane 6, and, as a matter of fact, more than
a year of unusually cold weather did fol
lownot only in the United States but In
Europe also.
Following the great volcanic outburst
of Krakatoa. In 1SSS, there were two years
of red' sunsets all over the world, due to a
dust-cloud that enveloped the entire earth.
The dust originated from one spot,
Krakatoa, but soon it was distributed by
the winds everywhere throughout the up
per atmospheric levels. And that is what
happens more or less whenever there Is a
volcanic outburst anywhere in the world
Krakatoa was a mountainous island In the
Straits of Sunda, between Java and Su
matra, but the dust It threw up on the
occasion mentioned gave the United States
three cool Summers and three very cold
Winters. All over, the earth the tempera
ture was below normal for that length of
time.
Krakatoa literally blew Itself to pieces.
It killed 10,000 natives dwelling along the
shores of the Straits, in the middle of
which, in a single night, it built up a
brand-new mountain twenty-five miles In
circumference and two miles high. The
explosions were so tremendous as to be
mistaken at a distance of 2,000 miles for
cannonading.
Pelee. on the island of Martinique, blew
its head off In 1902. It was a disaster far
greater than that which overwhelmed
Pompeii and Ilerculaneum. because the
loss of human lives was much greater. It
was a much more tremendous outburst
than that of Vesuvius In 79 A. D.. and the
dust it kicked up kept us cold for a year
thereafter.

Mount Toinbnro. at tho oaBt end of Java,
which destroyed 56,000 lives. For three
days darkness prevailed over all that

The greatest volcanic catastrophe in his
tory occurred in 1783, when Aaamayama,
on the main island of Japan, blew up.
The mountain throw great volumes of dust
to a height of fifty miles, and for years the
atmosphere all over the earth was foggy
with It.
Benjamin Franklin wroto: "There was

a fog all over Europe. It waB of a per
manent nature and dry. Bays of the sun
passing through It were so faint that, when
collected In the focus of a burning-glass,
they would scarcely kindle paper." .
Franklin's statement illustrates the idea
perfectly. The sun's rays could not get
through the dust-fog to the earth, or at all
events suffered so much interference that
the heat supply furnished by the orb was
largely shut off. No wonder that tho fol
lowing Winter 1783-4 was severe. The
next two years albo were very cold.
A volcano in Japau, on the other sldo of

Americans chilly and run up tho coal bills!
Few of us In tho United States, being
happily free from danger of destruction by
volcanoes, realize how plentiful and how
widely distributed are such burning moun
tains In many other parts of the world.
