very scalp tremble with the air that
time in yorr life you realize tia.
sound may innict physical pain a,.s
that there is possibility that it ray
kill.
No sooner is the big valve opened
than you feel the pressure against your
eardrums. A big wad of cotton seems
thrust into each ear. and two big I'm
gers seem to push the wads more end
more firmly until each time when you
swallow or blow into your nose the
sensation disappears only to begin
anew. Should you purposely delay
swallowing. within twenty seconds the
pain becomes intense and finally ex
circulating, as if pair of knitting nee
dies were being pushed deep into your
ears.
Nothing short of the faith that 9th
ers successfully withstand these sen.
sations prevents you from becoming
unduly excited, for actually you are
in the throes of about as disagreeable
a situation as you care to meet. For
the eternity Of half a minute the
racket and fog and ear pains continue.
Then the noise ceases as suddenly as it
began. Out of the fog comes the voice
OF your guide:
Feeling ali right? Ears all right?
No trouble TO breathe? oh. you'll be
all rightr' Again the valve screeches
and the air drones. the top of your
head throbs, and you are shaken with
in and without.
Gradually, after the lapse Of ten
minutes, when the pressures in the
heading and the lock become more
equalized, the din begins to slacken;
then it falls more and more and fades
to nothing, after which the lockman
opens the heading door and you gaze
upon another length of tube like that
you left behind.
How does it feel to be under forty
pounds pressure? There is no sensa-
ton to it-none whatever-which is
the trouble, for In case your heart is
going to give out there is no warning
symptom until too late. Against ey-
cry square foot of the surface OF your
body is pressure of 5,760 pounds, and
the only thing that prevents you from
being squashed is the 5,760 pounds
per square foot pressure inside of you.

Inc pressure from without is SO
great that were 1t not for the pressure
within you would be smashed fat as
toad run over by a steam roller, and
the pressure within you is so great
that were it not counterbalanced by
the pressure from without you would
explode to atoms like the shell of
dynamite cartridge.
Yet you have no means of realizing
this. You feel perfectly natural You
breathe normally and without effort.
You move about without being con-
scious of exertion. Only feeling as

remains.
The noise of rumbling cars and
scraping shovels from ahead sounds
natural. So does the voice of your
guide. Only your own voice seems

and far off. not as If it came from your
own mouth, but as If from ten feet be-

until you have found the cause, all
sounds are chopped off short, for in
this heavy atmosphere there is little
echo and carrying power. Even the

TO try to whistle with your lips or to
blow cornet or fife you might blow
your lungs out without producing q
sound. for the pressure would resist |
any sound waves of which your lungs |
we're capable. Owing TO the excessive

match it would burn with the rapldity |

For the same reason an oil lamp or |
a lantern would burn itself out within |
q few minutes, emitting volumes OF

flames. And for the same reason q /
