"I can. A friend of mine, a reporter on one of the London dailies, once
gave me a few lessons, and, becoming fond of the subject, I followed it
up."

"That is well; you did well. It is of immense advantage to a man,
whatever his position in life, that he should be able to write shorthand
with facility. Especially useful is it in commerce. I know that, having
had some experience of commercial life."

At this point in the conversation Nigel was startled by what was to him
an absolutely new sensation, namely a shaking or trembling of the whole
cavern, accompanied by faint rumbling sounds as if in deeper caverns
below him.

He glanced quickly at his host and at the negro, but to his surprise
these remarkable men seemed not to be aware of the shaking, although it
was severe enough to cause some of the furniture to rattle. Observing
his look of surprise, Moses remarked, with a benignant though capacious
smile, "Mountain's got de mulligrumps pritty bad jist now."

"We are pretty well accustomed to that," said the host, observing that
Nigel turned to him for an explanation. "No doubt you are aware that
this region is celebrated for earthquakes and volcanoes, so much so that
the inhabitants pay little attention to them unless they become
unusually violent. This island of Krakatoa is itself the fragment of an
extinct volcano; but the term 'extinct' is scarcely applicable to
volcanoes, for it is well known that many which were for centuries
supposed to be extinct have awakened to sudden and violent
activity--'quiescent' might be a more appropriate term."
