This very day something occurred which gave rise to another most regrettable altercation between Robur and his guests. This was provoked by Frycollin, who, finding himself above the boundless sea, was seized with another fit of terror. Like a child, like the Negro he was, he gave himself over to groaning and protesting and crying, and writhing in a thousand contortions and grimaces.

"I want to get out! I want to get out! I am not a bird! Boohoo! I don't want to fly, I want to get out!"

Uncle Prudent, as may be imagined, did not attempt to quiet him. In fact, he encouraged him, and particularly as the incessant howling seemed to have a strangely irritating effect on Robur.

When Tom Turner and his companions were getting ready for fishing, the engineer ordered them to shut up Frycollin in his cabin. But the Negro never ceased his jumping about, and began to kick at the wall and yell with redoubled power.

It was noon. The "Albatross" was only about fifteen or twenty feet above the water. A few ships, terrified at the apparition, sought safety in flight.

As may be guessed, a sharp look-out was kept on the prisoners, whose temptation to escape could not but be intensified. Even supposing they jumped overboard they would have been picked up by the india-rubber boat. As there was nothing to do during the fishing, in which Phil Evans intended to take part, Uncle Prudent, raging furiously as usual, retired to his cabin.

The Caspian Sea is a volcanic depression. Into it flow the waters of the Volga, the Ural, the Kour, the Kouma, the Jemba, and others.

Without the evaporation which relieves it of its overflow, this basin, with an area of 17,000 square miles, and a depth of from sixty to four hundred feet, would flood the low marshy ground to its north and east. Although it is not in communication with the Black Sea or the Sea of Aral, being at a much lower level than they are, it contains an immense number of fish--such fish, be it understood, as can live in its bitter waters, the bitterness being due to the naphtha which pours in from the springs on the south.

The crew of the "Albatross" made no secret of their delight at the change in their food the fishing would bring them.

"Look out!" shouted Turner, as he harpooned a good-size fish, not unlike a shark.

It was a splendid sturgeon seven feet long, called by the Russians beluga, the eggs of which mixed up with salt, vinegar, and white wine form caviar. Sturgeons from the river are, it may be, rather better than those from the sea; but these were welcomed warmly enough on board the "Albatross."

But the best catches were made with the drag-nets, which brought up at each haul carp, bream, salmon, salt.w.a.ter pike, and a number of medium-sized sterlets, which wealthy gourmets have sent alive to Astrakhan, Moscow, and Petersburg, and which now pa.s.sed direct from their natural element into the cook's kettle without any charge for transport.

An hour's work sufficed to fill up the larders of the aeronef, and she resumed her course to the north.

During the fishing Frycollin had continued shouting and kicking at his cabin wall, and making a tremendous noise.

"That wretched n.i.g.g.e.r will not be quiet, then?" said Robur, almost out of patience.

"It seems to me, sir, he has a right to complain," said Phil Evans.

"Yes, and I have a right to look after my ears," replied Robur.

"Engineer Robur!" said Uncle Prudent, who had just appeared on deck.

"President of the Weldon Inst.i.tute!"

They had stepped up to one another, and were looking into the whites of each other's eyes. Then Robur shrugged his shoulders. "Put him at the end of a line," he said.

Turner saw his meaning at once. Frycollin was dragged out of his cabin. Loud were his cries when the mate and one of the men seized him and tied him into a tub, which they hitched on to a rope--one of those very ropes, in fact, that Uncle Prudent had intended to use as we know.

The Negro at first thought he was going to be hanged. Not he was only going to be towed!

The rope was paid out for a hundred feet and Frycollin found himself hanging in s.p.a.ce.

He could then shout at his ease. But fright contracted his larynx, and he was mute.

Uncle Prudent and Phil Evans endeavored to prevent this performance.

They were thrust aside.

"It is scandalous! It is cowardly!" said Uncle Prudent, quite beside himself with rage.

"Indeed!" said Robur.

"It is an abuse of power against which I protest."

"Protest away!"

"I will be avenged, Mr. Robur."

"Avenge when you like, Mr. Prudent."

"I will have my revenge on you and yours."

The crew began to close up with anything but peaceful intentions.

Robur motioned them away.

"Yes, on you and yours!" said Uncle Prudent, whom his colleague in vain tried to keep quiet.

"Whenever you please!" said the engineer.

"And in every possible way!"

"That is enough now," said Robur, in a threatening tone. "There are other ropes on board. And if you don't be quiet I'll treat you as I have done your servant!"

Uncle Prudent was silent, not because he was afraid, but because his wrath had nearly choked him; and Phil Evans led him off to his cabin.

During the last hour the air had been strangely troubled. The symptoms could not be mistaken. A storm was threatening. The electric saturation of the atmosphere had become so great that about half-past two o'clock Robur witnessed a phenomenon that was new to him.

In the north, whence the storm was traveling, were spirals of half-luminous vapor due to the difference in the electric charges of the various beds of cloud. The reflections of these bands came running along the waves in myriads of lights, growing in intensity as the sky darkened.

The "Albatross" and the storm were sure to meet, for they were exactly in front of each other.

And Frycollin? Well! Frycollin was being towed--and towed is exactly the word, for the rope made such an angle, with the aeronef, now going at over sixty knots an hour, that the tub was a long way behind her.

The crew were busy in preparing for the storm, for the "Albatross"

would either have to rise above it or drive through its lowest layers. She was about three thousand feet above the sea when a clap of thunder was heard. Suddenly the squall struck her. In a few seconds the fiery clouds swept on around her.

Phil Evans went to intercede for Frycollin, and asked for him to be taken on board again. But Robur had already given orders to that effect, and the rope was being hauled in, when suddenly there took place an inexplicable slackening in the speed of the screws.

The engineer rushed to the central deck-house. "Power! More power!"

he shouted. "We must rise quickly and get over the storm!"

"Impossible, sir!"

"What is the matter?"

"The currents are troubled! They are intermittent!" And, in fact, the "Albatross" was falling fast.

As with the telegraph wires on land during a storm, so was it with the acc.u.mulators of the aeronef. But what is only an inconvenience in the case of messages was here a terrible danger.
