The stupefaction of the crowd was indescribable as they saw one of their waganga thus whirled away into space.

"Huzza!" roared Joe, as the balloon--thanks to its ascensional force--shot up higher into the sky, with increased rapidity.

"He holds on well," said Kennedy; "a little trip will do him good."

"Shall we let this darky drop all at once?" inquired Joe.

"Oh no," replied the doctor, "we'll let him down easily; and I warrant me that, after such an adventure, the power of the wizard will be enormously enhanced in the sight of his comrades."

"Why, I wouldn't put it past them to make a god of him!" said Joe, with a laugh.

The Victoria, by this time, had risen to the height of one thousand feet, and the black hung to the rope with desperate energy. He had become completely silent, and his eyes were fixed, for his terror was blended with amazement. A light west wind was sweeping the balloon right over the town, and far beyond it.

Half an hour later, the doctor, seeing the country deserted, moderated the flame of his cylinder, and descended toward the ground. At twenty feet above the turf, the affrighted sorcerer made up his mind in a twinkling: he let himself drop, fell on his feet, and scampered off at a furious pace toward Kazeh; while the balloon, suddenly relieved of his weight, again shot up on her course.

CHAPTER SIXTEENTH.

Symptoms of a Storm.--The Country of the Moon.--The Future of the African Continent.--The Last Machine of all.--A View of the Country at Sunset.-- Flora and Fauna.--The Tempest.--The Zone of Fire.--The Starry Heavens.

"See," said Joe, "what comes of playing the sons of the moon without her leave! She came near serving us an ugly trick. But say, master, did you damage your credit as a physician?"

"Yes, indeed," chimed in the sportsman. "What kind of a dignitary was this Sultan of Kazeh?"

"An old half-dead sot," replied the doctor, "whose loss will not be very severely felt. But the moral of all this is that honors are fleeting, and we must not take too great a fancy to them."

"So much the worse!" rejoined Joe. "I liked the thing--to be worshipped!--Play the god as you like! Why, what would any one ask more than that? By-the-way, the moon did come up, too, and all red, as if she was in a rage."

While the three friends went on chatting of this and other things, and Joe examined the luminary of night from an entirely novel point of view, the heavens became covered with heavy clouds to the northward, and the lowering masses assumed a most sinister and threatening look. Quite a smart breeze, found about three hundred feet from the earth, drove the balloon toward the north-northeast; and above it the blue vault was clear; but the atmosphere felt close and dull.

The aeronauts found themselves, at about eight in the evening, in thirty-two degrees forty minutes east longitude, and four degrees seventeen minutes latitude. The atmospheric currents, under the influence of a tempest not far off, were driving them at the rate of from thirty to thirty-five miles an hour; the undulating and fertile plains of Mfuto were passing swiftly beneath them. The spectacle was one worthy of admiration--and admire it they did.

"We are now right in the country of the Moon," said Dr. Ferguson; "for it has retained the name that antiquity gave it, undoubtedly, because the moon has been worshipped there in all ages. It is, really, a superb country."

"It would be hard to find more splendid vegetation."

"If we found the like of it around London it would not be natural, but it would be very pleasant," put in Joe. "Why is it that such savage countries get all these fine things?"

"And who knows," said the doctor, "that this country may not, one day, become the centre of civilization? The races of the future may repair hither, when Europe shall have become exhausted in the effort to feed her inhabitants."

"Do you think so, really?" asked Kennedy.

"Undoubtedly, my dear Dick. Just note the progress of events: consider the migrations of races, and you will arrive at the same conclusion assuredly.
