It would be a terrible journey.  The engineer only feared one thing; it was that the balloon, held to the ground and dashed about by the wind, would be torn into shreds.  For several hours he roamed round the nearly-deserted square, surveying the apparatus.  Pencroft did the same on his side, his hands in his pockets, yawning now and then like a man who did not know how to kill the time, but really dreading, like his friend, either the escape or destruction of the balloon.  Evening arrived.  The night was dark in the extreme.  Thick mists passed like clouds close to the ground.  Rain fell mingled with snow. it was very cold.  A mist hung over Richmond. it seemed as if the violent storm had produced a truce between the besiegers and the besieged, and that the cannon were silenced by the louder detonations of the storm.  The streets of the town were deserted.  It had not even appeared necessary in that horrible weather to place a guard in the square, in the midst of which plunged the balloon.  Everything favored the departure of the prisoners, but what might possibly be the termination of the hazardous voyage they contemplated in the midst of the furious elements?—­

“Dirty weather!” exclaimed Pencroft, fixing his hat firmly on his head with a blow of his fist; “but pshaw, we shall succeed all the same!”

At half-past nine, Harding and his companions glided from different directions into the square, which the gas-lamps, extinguished by the wind, had left in total obscurity.  Even the enormous balloon, almost beaten to the ground, could not be seen.  Independently of the sacks of ballast, to which the cords of the net were fastened, the car was held by a strong cable passed through a ring in the pavement.  The five prisoners met by the car.  They had not been perceived, and such was the darkness that they could not even see each other.

Without speaking a word, Harding, Spilett, Neb, and Herbert took their places in the car, while Pencroft by the engineer’s order detached successively the bags of ballast.  It was the work of a few minutes only, and the sailor rejoined his companions.

The balloon was then only held by the cable, and the engineer had nothing to do but to give the word.

At that moment a dog sprang with a bound into the car.  It was Top, a favorite of the engineer.  The faithful creature, having broken his chain, had followed his master.  He, however, fearing that its additional weight might impede their ascent, wished to send away the animal.

“One more will make but little difference, poor beast!” exclaimed Pencroft, heaving out two bags of sand, and as he spoke letting go the cable; the balloon ascending in an oblique direction, disappeared, after having dashed the car against two chimneys, which it threw down as it swept by them.

Then, indeed, the full rage of the hurricane was exhibited to the voyagers.  During the night the engineer could not dream of descending, and when day broke, even a glimpse of the earth below was intercepted by fog.
