nd yet all the while certain, and as it were, involuntary observations
determined my convictions. By the doubtful glare of the torch, I could
make out some singular changes in the granitic strata; a strange and
terrible phenomenon was about to be produced, in which electricity
played a part.

Then this boiling water, this terrible and excessive heat? I determined
as a last resource to examine the compass.

The compass had gone mad!

Yes, wholly stark staring mad. The needle jumped from pole to pole with
sudden and surprising jerks, ran round, or as it is said, boxed the
compass, and then ran suddenly back again as if it had the vertigo.

I was aware that, according to the best acknowledged theories, it was a
received notion that the mineral crust of the globe is never, and never
has been, in a state of complete repose.

It is perpetually undergoing the modifications caused by the
decomposition of internal matter, the agitation consequent on the
flowing of extensive liquid currents, the excessive action of magnetism
which tends to shake it incessantly, at a time when even the
multitudinous beings on its surface do not suspect the seething process
to be going on.

Still this phenomenon would not have alarmed me alone; it would not have
aroused in my mind a terrible, an awful idea.

But other facts could not allow my self-delusion to last.

Terrible detonations, like Heaven's artillery, began to multiply
themselves with fearful intensity. I could only compare them with the
noise made by hundreds of heavily laden chariots being madly driven over
a stone pavement. It was a continuous roll of heavy thunder.

And then the mad compass, shaken by the wild electric phenomena,
confirmed me in my rapidly formed opinion. The mineral crust was about
to burst, the heavy granite masses were about to rejoin, the fissure was
about to close, the void was about to be filled up, and we poor atoms to
be crushed in its awful embrace!

"Uncle, Uncle!" I cried, "we are wholly, irretrievably lost!"

"What, then, my young friend, is your new cause of terror and alarm?" he
said in his calmest manner. "What fear you now?"

"What do I fear now!" I cried in fierce and angry tones. "Do you not see
that the walls of the shaft are in motion? Do you not see that the solid
granite masses are cracking? Do you not feel the terrible, torrid heat?
Do you not observe the awful boiling water on which we float? Do you not
remark this mad needle? Ev
