"What! take sixty-four and a half days, to fall?" exclaimed Johnson.
"Yes, we are ninety-five millions of miles off. But when I say the Pole is motionless, it is not strictly true; it is only so in comparison with the rest of the globe, for it has a certain movement of its own, and completes a circle in about twenty-six thousand years. This comes from the precession of the equinoxes."
A long and learned talk was started on this subject between Altamont and the Doctor, simplified, however, as much as possible for the benefit of Bell and Johnson.
Hatteras took no part in it, and even when they went on to speculate about the earth's centre, and discussed several of the theories that had been advanced respecting it, he seemed not to hear; it was evident his thoughts were far away.
Among other opinions put forth was one in our own days, which greatly excited Altamont's surprise. It was held that there was an immense opening at the poles which led into the heart of the earth, and that it was out of the opening that the light of the Aurora Borealis streamed. This was gravely stated, and Captain Synness, a countryman of our own, actually proposed that Sir Humphrey Davy, Humboldt, and Arago should undertake an expedition through it, but they refused."
"And quite right too," said Altamont.
"So say I; but you see, my friends, what absurdities imagination has conjured up about these regions, and how, sooner or later, the simple reality comes to light."
