Robur the Conqueror

Chapter 18. Over The Volcano
The sea was as rough as ever, and the symptoms became alarming. The
barometer fell several millimeters. The wind came in violent gusts, and then for a
moment or so failed altogether. Under such circumstances a sailing vessel would
have had to reef in her topsails and her foresail. Everything showed that the wind
was rising in the northwest. The storm-glass became much troubled and its
movements were most disquieting.
At one o'clock in the morning the wind came on again with extreme violence.
Although the aeronef was going right in its teeth she was still making progress at
a rate of from twelve to fifteen miles an hour. But that was the utmost she could
Evidently preparations must be made for a cyclone, a very rare occurrence in
these latitudes. Whether it be called a hurricane, as in the Atlantic, a typhoon, as
in Chinese waters a simoom, as in the Sahara, or a tornado, as on the western
coast, such a storm is always a gyratory one, and most dangerous for any ship
caught in the current which increases from the circumference to the center, and
has only one spot of calm, the middle of the vortex.
Robur knew this. He also knew it was best to escape from the cyclone and get
beyond its zone of attraction by ascending to the higher strata. Up to then he had
always succeeded in doing this, but now he had not an hour, perhaps not a
minute, to lose.
In fact the violence of the wind sensibly increased. The crests of the waves were
swept off as they rose and blown into white dust on the surface of the sea. It was
manifest that the cyclone was advancing with fearful velocity straight towards the
regions of the pole.
"Higher!" said Robur.
"Higher it is," said Tom Turner.
An extreme ascensional power was communicated to the aeronef, and she shot
up slantingly as if she was traveling on a plane sloping downwards from the
southwest. Suddenly the barometer fell more than a dozen millimeters and the
"Albatross" paused in her ascent.
What was the cause of the stoppage? Evidently she was pulled back by the air;
some formidable current had diminished the resistance to the screws. When a
steamer travels upstream more work is got out of her screw than when the water
is running between the blades. The recoil is then considerable, and may perhaps
be as great as the current. It was thus with the "Albatross" at this moment.
But Robur was not the man to give in. His seventy-four screws, working perfectly
together, were driven at their maximum speed. But the aeronef could not escape;
the attraction of the cyclone was irresistible. During the few moments of calm she
began to ascend, but the heavy pull soon drew her back, and she sunk like a
ship as she founders.
Evidently if the violence of the cyclone went on increasing the "Albatross" would
be but as a straw caught in one of those whirlwinds that root up the trees, carry
off roofs, and blow down walls.
