<h3 id="sigil_toc_id_92">THE SOUTHERN HEMISPHERE.</h3>
<p>The projectile had just escaped a terrible danger, and a very
unforeseen one. Who would have thought of such a rencontre with
meteors? These erring bodies might create serious perils for the
travellers. They were to them so many sandbanks upon that sea of
ether which, less fortunate than sailors, they could not escape. But
did these adventurers complain of space? No, not since nature had
given them the splendid sight of a cosmical meteor bursting from
expansion, since this inimitable firework, which no Ruggieri could
imitate, had lit up for some seconds the invisible glory of the moon.
In that flash, continents, seas, and forests had become visible to
them. Did an atmosphere, then, bring to this unknown face its
life-giving atoms? Questions still insoluble, and for ever closed
against human curiosity!</p>
<p>It was then half past three in the afternoon. The projectile was
following its curvilinear direction round the moon. Had its course
been again altered by the meteor? It was to be feared so. But the
projectile must describe a curve unalterably determined by the laws
of mechanical reasoning. Barbicane was inclined to believe that this
curve would be rather a parabola than a hyperbola. But admitting the
parabola, the projectile must quickly have passed through the cone of
shadow projected into space opposite the sun. This cone, indeed, is
very narrow, the angular diameter of the moon being so little when
compared with the diameter of the orb of day; and up to this time the
projectile had been floating in this deep shadow. Whatever had been
its speed (and it could not have been insignificant) its period of
occultation continued. That was evident, but perhaps that would not
have been the case in a supposed rigidly parabolical trajectory,—a
new problem which tormented Barbicane's brain, imprisoned as he was
in a circle of unknowns which he could not unravel.</p>

<p>Neither of the travellers thought of taking an instant's repose.
Each one watched for an unexpected fact, which might throw some new
light on their uranographic studies. About five o'clock, Michel Ardan
distributed, under the name of dinner, some pieces of bread and cold
meat, which were quickly swallowed without either of them abandoning
their scuttle, the glass of which was incessantly encrusted by the
condensation of vapour.</p>
<p>About forty-five minutes past five in the evening, Nicholl, armed
with his glass, sighted towards the southern border of the moon, and
in the direction followed by the projectile, some bright points cut
upon the dark shield of the sky. They looked like a succession of
sharp points lengthened into a tremulous line. They were very bright.
Such appeared the terminal line of the moon when in one of her
octants.</p>
<p>They could not be mistaken. It was no longer a simple meteor. This
luminous ridge had neither colour nor motion. Nor was it a volcano in
eruption. And Barbicane did not hesitate to pronounce upon it.</p>
<p>"The sun!" he exclaimed.</p>
<p>"What! the sun?" answered Nicholl and Michel Ardan.</p>
<p>"Yes, my friends, it is the radiant orb itself lighting up the
summit of the mountains situated on the southern borders of the moon.
We are evidently nearing the south pole."</p>
<p>"After having passed the north pole," replied Michel. "We have
made the circuit of our satellite, then?"</p>
<p>"Yes, my good Michel."</p>
<p>"Then, no more hyperbolas, no more parabolas, no more open curves
to fear?"</p>
<p>"No, but a <i>closed</i> curve."</p>
<p>"Which is called—"</p>
<p>"An ellipse. Instead of losing itself in interplanetary space, it
is probable that the projectile will describe an elliptical orbit
around the moon."</p>
<p>"Indeed!"</p>
<p>"And that it will become <i>her</i> satellite."</p>
<p>"Moon of the moon!" cried Michel Ardan.</p>
<p>"Only, I would have you observe, my worthy friend," replied
Barbicane, "that we are none the less lost for that."</p>
<p>"Yes, in another manner, and much more pleasantly," answered the
careless Frenchman with his most amiable smile.</p>
