Five Weeks in a Balloon by Jules Verne (best novels to read to improve english txt) 📕
Description
Five Weeks in a Balloon tells the tale of three Englishmen who attempt to cross Africa, from east to west, in a balloon. Dr. Ferguson is the rational scientist leading the trio, accompanied by loyal sidekick Joe and the doctor’s sporting friend Kennedy.
The three embark on many adventures: They encounter natives and dangerous animals, experience problems with their ballooning technology, and struggle with the winds and the weather. Throughout the novel, the author liberally sprinkles descriptions of flora, fauna, and geography, as seen through nineteenth century eyes.
Though this is Verne’s first published book, he already demonstrates much of the formula that drive his later works: the well-defined characters led by a rational scientist, the focus on science and technology, and of course the adventure-filled plot.
The novel, first published in 1863, was topical for its time, as European interest in African exploration was strong. At the time the book was published, David Livingstone was midst-exploration in south-east Africa, and Burton and Speke had recently returned from exploring the Great Lakes region. The novel itself contains many references to actual expeditions that would have been current or recent for the original readers of the novel.

“The descent, of course, is effected by lowering the heat of the cylinder, and letting the temperature abate. The ascent would be, usually, more rapid than the descent; but that is a fortunate circumstance, since it is of no importance to me to descend rapidly, while, on the other hand, it is by a very rapid ascent that I avoid obstacles. The real danger lurks below, and not above.
“Besides, as I have said, I have a certain quantity of ballast, which will enable me to ascend more rapidly still, when necessary. My valve, at the top of the balloon, is nothing more nor less than a safety-valve. The balloon always retains the same quantity of hydrogen, and the variations of temperature that I produce in the midst of this shut-up gas are, of themselves, sufficient to provide for all these ascending and descending movements.
“Now, gentlemen, as a practical detail, let me add this:
“The combustion of the hydrogen and of the oxygen at the point of the cylinder produces solely the vapor or steam of water. I have, therefore, provided the lower part of the cylindrical iron box with a scape-pipe, with a valve operating by means of a pressure of two atmospheres; consequently, so soon as this amount of pressure is attained, the steam escapes of itself.
“Here are the exact figures: 25 gallons of water, separated into its constituent elements, yield 200 pounds of oxygen and 25 pounds of hydrogen. This represents, at atmospheric tension, 1,890 cubic feet of the former and 3,780 cubic feet of the latter, or 5,670 cubic feet, in all, of the mixture. Hence, the stopcock of my cylinder, when fully open, expends 27 cubic feet per hour, with a flame at least six times as strong as that of the large lamps used for lighting streets. On an average, then, and in order to keep myself at a very moderate elevation, I should not burn more than nine cubic feet per hour, so that my twenty-five gallons of water represent six hundred and thirty-six hours of aerial navigation, or a little more than twenty-six days.
“Well, as I can descend when I please, to replenish my stock of water on the way, my trip might be indefinitely prolonged.
“Such, gentlemen, is my secret. It is simple, and, like most simple things, it cannot fail to succeed. The dilation and contraction of the gas in the balloon is my means of locomotion, which calls for neither cumbersome wings, nor any other mechanical motor. A calorifere to produce the changes of temperature, and a cylinder to generate the heat, are neither inconvenient nor heavy. I think, therefore, that I have combined all the elements of success.”
Dr. Ferguson here terminated his discourse, and was most heartily applauded. There was not an objection to make to it; all had been foreseen and decided.
“However,” said the captain, “the thing may prove dangerous.”
“What matters that,” replied the doctor, “provided that it be practicable?”
XIThe arrival at Zanzibar—The English consul—Ill-will of the inhabitants—The island of Koumbeni—The rainmakers—Inflation of the balloon—Departure on the 18th of April—The last goodbye—The Victoria.
An invariably favorable wind had accelerated the progress of the Resolute toward the place of her destination. The navigation of the Mozambique Channel was especially calm and pleasant. The agreeable character of the trip by sea was regarded as a good omen of the probable issue of the trip through the air. Every one looked forward to the hour of arrival, and sought to give the last touch to the doctor’s preparations.
At length the vessel hove in sight of the town of Zanzibar, upon the island of the same name, and, on the 15th of April, at 11 o’clock in the morning, she anchored in the port.
The island of Zanzibar belongs to the Imam of Muscat, an ally of France and England, and is, undoubtedly, his finest settlement. The port is frequented by a great many vessels from the neighboring countries.
The island is separated from the African coast only by a channel, the greatest width of which is but thirty miles.
It has a large trade in gums, ivory, and, above all, in “ebony,” for Zanzibar is the great slave-market. Thither converges all the booty captured in the battles which the chiefs of the interior are continually fighting. This traffic extends along the whole eastern coast, and as far as the Nile latitudes. Mr. G. Lejean even reports that he has seen it carried on, openly, under the French flag.
Upon the arrival of the Resolute, the English consul at Zanzibar came on board to offer his services to the doctor, of whose projects the European newspapers had made him aware for a month past. But, up to that moment, he had remained with the numerous phalanx of the incredulous.
“I doubted,” said he, holding out his hand to Dr. Ferguson, “but now I doubt no longer.”
He invited the doctor, Kennedy, and the faithful Joe, of course, to his own dwelling. Through his courtesy, the doctor was enabled to have knowledge of the various letters that he had received from Captain Speke. The captain and his companions had suffered dreadfully from hunger and bad weather before reaching the Ugogo country. They could advance only with extreme difficulty, and did not expect to be able to communicate again for a long time.
“Those are perils and privations which we shall manage to avoid,” said the doctor.
The baggage of the three travellers was conveyed to the consul’s residence. Arrangements were made for disembarking the balloon upon the beach at Zanzibar. There was a convenient spot, near the signal-mast, close by an immense building, that would serve to shelter it from the east winds. This huge tower, resembling a tun standing
