Well, at the rate of two hundred and forty miles every twelve hours, which does not come near the rapidity of our railroad trains, by travelling day and night, it would take only seven days to cross Africa!"

"But then you could see nothing, make no geographical observations, or reconnoitre the face of the country."

"Ah!" replied the doctor, "if I am master of my balloon—if I can ascend and descend at will, I shall stop when I please, especially when too violent currents of air threaten to carry me out of my way with them."

"And you will encounter such," said Captain Bennet. "There are tornadoes that sweep at the rate of more than two hundred and forty miles per hour."

"You see, then, that with such speed as that, we could cross Africa in twelve hours. One would rise at Zanzibar, and go to bed at St. Louis!"

"But," rejoined the officer, "could any balloon withstand the wear and tear of such velocity?"

"It has happened before," replied Ferguson.

"And the balloon withstood it?"

"Perfectly well. It was at the time of the coronation of Napoleon, in 1804. The aeronaut, Gernerin, sent up a balloon at Paris, about eleven o'clock in the evening. It bore the following inscription, in letters of gold: 'Paris, 25 Frimaire; year XIII; Coronation of the Emperor Napoleon by his Holiness, Pius VII.' On the next morning, the inhabitants of Rome saw the same balloon soaring above the Vatican, whence it crossed the Campagna, and finally fluttered down into the lake of Bracciano. So you see, gentlemen, that a balloon can resist such velocities."

"A balloon—that might be; but a man?" insinuated Kennedy.

"Yes, a man, too!—for the balloon is always motionless with reference to the air that surrounds it. What moves is the mass of the atmosphere itself: for instance, one may light a taper in the car, and the flame will not even waver. An aeronaut in Garnerin's balloon would not have suffered in the least from the speed. But then I have no occasion to attempt such velocity; and if I can anchor to some tree, or some favorable inequality of the ground, at night, I shall not fail to do so. Besides, we take provision for two months with us, after all; and there is nothing to prevent our skilful huntsman here from furnishing game in abundance when we come to alight."

"Ah! Mr. Kennedy," said a young midshipman, with envious eyes, "what splendid shots you'll have!"

"Without counting," said another, "that you'll have the glory as well as the sport!"

"Gentlemen," replied the hunter, stammering with confusion, "I greatly—appreciate—your compliments— but they—don't—belong to me."

"You!" exclaimed every body, "don't you intend to go?"

"I am not going!"

"You won't accompany Dr. Ferguson?"

"Not only shall I not accompany him, but I am here so as to be present at the last moment to prevent his going."

Every eye was now turned to the doctor.

"Never mind him!" said the latter, calmly. "This is a matter that we can't argue with him. At heart he knows perfectly well that he IS going."

"By Saint Andrew!" said Kennedy, "I swear—"

"Swear to nothing, friend Dick; you have been ganged and weighed—you and your powder, your guns, and your bullets; so don't let us say anything more about it."

And, in fact, from that day until the arrival at Zanzibar, Dick never opened his mouth. He talked neither about that nor about anything else. He kept absolutely silent.

CHAPTER NINTH.

They double the Cape.—The Forecastle.—A Course of Cosmography by Professor Joe.—Concerning the Method of guiding Balloons.—How to seek out Atmospheric Currents.—Eureka.

The Resolute plunged along rapidly toward the Cape of Good Hope, the weather continuing fine, although the sea ran heavier.

On the 30th of March, twenty-seven days after the departure from London, the Table Mountain loomed up on the horizon. Cape City lying at the foot of an amphitheatre of hills, could be distinguished through the ship's glasses, and soon the Resolute cast anchor in the port. But the captain touched there only to replenish his coal bunkers, and that was but a day's job. On the morrow, he steered away to the south'ard, so as to double the southernmost point of Africa, and enter the Mozambique Channel.

This was not Joe's first sea-voyage, and so, for his part, he soon found himself at home on board; every body liked him for his frankness and good-humor. A considerable share of his master's renown was reflected upon him. He was listened to as an oracle, and he made no more mistakes than the next one.

So, while the doctor was pursuing his descriptive course of lecturing in the officers' mess, Joe reigned supreme on the forecastle, holding forth in his own peculiar manner, and making history to suit himself—a style of procedure pursued, by the way, by the greatest historians of all ages and nations.

The topic of discourse was, naturally, the aerial voyage. Joe had experienced some trouble in getting the rebellious spirits to believe in it; but, once accepted by them, nothing connected with it was any longer an impossibility to the imaginations of the seamen stimulated by Joe's harangues.

Our dazzling narrator persuaded his hearers that, after this trip, many others still more wonderful would be undertaken. In fact, it was to be but the first of a long series of superhuman expeditions.

"You see, my friends, when a man has had a taste of that kind of travelling, he can't get along afterward with any other; so, on our next expedition, instead of going off to one side, we'll go right ahead, going up, too, all the time."

"Humph! then you'll go to the moon!" said one of the crowd, with a stare of amazement.

"To the moon!" exclaimed Joe, "To the moon! pooh! that's too common. Every body might go to the moon, that way. Besides, there's no water there, and you have to carry such a lot of it along with you. Then you have to take air along in bottles, so as to breathe."

"Ay! ay! that's all right! But can a man get a drop of the real stuff there?" said a sailor who liked his toddy.

"Not a drop!" was Joe's answer. "No! old fellow, not in the moon. But we're going to skip round among those little twinklers up there—the stars—and the splendid planets that my old man so often talks about. For instance, we'll commence with Saturn—"

"That one with the ring?" asked the boatswain.

"Yes! the wedding-ring—only no one knows what's become of his wife!"

"What? will you go so high up as that?" said one of the ship-boys, gaping with wonder. "Why, your master must be Old Nick himself."

"Oh! no, he's too good for that."

"But, after Saturn—what then?" was the next inquiry of his impatient audience.

"After Saturn? Well, we'll visit Jupiter. A funny place that is, too, where the days are only nine hours and a half long—a good thing for the lazy fellows—and the years, would you believe it—last twelve of ours, which is fine for folks who have only six months to live. They get off a little longer by that."

"Twelve years!" ejaculated the boy.

"Yes, my youngster; so that in that country you'd be toddling after your mammy yet, and that old chap yonder, who looks about fifty, would only be a little shaver of four and a half."

"Blazes! that's a good 'un!" shouted the whole forecastle together.

"Solemn truth!" said Joe, stoutly.

"But what can you expect? When people will stay in this world, they learn nothing and keep as ignorant as bears. But just come along to Jupiter and you'll see. But they have to look out up there, for he's got satellites that are not just the easiest things to pass."

All the men laughed, but they more than half believed him.
