“We are going up, doctor!”
“Quicker, quicker still!”
In this part of Africa, during the equatorial storms, it is not rare to count from thirty to thirty-five flashes of lightning per minute. The sky is literally on fire, and the crashes of thunder are continuous.
The wind burst forth with frightful violence in this burning atmosphere; it twisted the blazing clouds; one might have compared it to the breath of some gigantic bellows, fanning all this conflagration.
Dr. Ferguson kept his cylinder at full heat, and the balloon dilated and went up, while Kennedy, on his knees, held together the curtains of the awning. The balloon whirled round wildly enough to make their heads turn, and the aeronauts got some very alarming jolts, indeed, as their machine swung and swayed in all directions. Huge cavities would form in the silk of the balloon as the wind fiercely bent it in, and the stuff fairly cracked like a pistol as it flew back from the pressure. A sort of hail, preceded by a rumbling noise, hissed through the air and rattled on the covering of the Victoria. The latter, however, continued to ascend, while the lightning described tangents to the convexity of her circumference; but she bore on, right through the midst of the fire.
“God protect us!” said Dr. Ferguson, solemnly, “we are in His hands; He alone can save us—but let us be ready for every event, even for fire—our fall could not be very rapid.”
The doctor’s voice could scarcely be heard by his companions; but they could see his countenance calm as ever even amid the flashing of the lightnings; he was watching the phenomena of phosphorescence produced by the fires of St. Elmo, that were now skipping to and fro along the network of the balloon.
The latter whirled and swung, but steadily ascended, and, ere the hour was over, it had passed the stormy belt. The electric display was going on below it like a vast crown of artificial fireworks suspended from the car.
Then they enjoyed one of the grandest spectacles that Nature can offer to the gaze of man. Below them, the tempest; above them, the starry firmament, tranquil, mute, impassible, with the moon projecting her peaceful rays over these angry clouds.
Dr. Ferguson consulted the barometer; it announced twelve thousand feet of elevation. It was then eleven o’clock at night.
“Thank Heaven, all danger is past; all we have to do now, is, to keep ourselves at this height,” said the doctor.
“It was frightful!” remarked Kennedy.
“Oh!” said Joe, “it gives a little variety to the trip, and I’m not sorry to have seen a storm from a trifling distance up in the air. It’s a fine sight!”
CHAPTER SEVENTEENTH.
The Mountains of the Moon.—An Ocean of Verdure.—They cast Anchor.—The Towing Elephant.—A Running Fire.—Death of the Monster.—The Field-Oven.—A Meal on the Grass.—A Night on the Ground.
About four in the morning, Monday, the sun reappeared in the horizon; the clouds had dispersed, and a cheery breeze refreshed the morning dawn.
The earth, all redolent with fragrant exhalations, reappeared to the gaze of our travellers. The balloon, whirled about by opposing currents, had hardly budged from its place, and the doctor, letting the gas contract, descended so as to get a more northerly direction. For a long while his quest was fruitless; the wind carried him toward the west until he came in sight of the famous Mountains of the Moon, which grouped themselves in a semicircle around the extremity of Lake Tanganayika; their ridges, but slightly indented, stood out against the bluish horizon, so that they might have been mistaken for a natural fortification, not to be passed by the explorers of the centre of Africa. Among them were a few isolated cones, revealing the mark of the eternal snows.
“Here we are at last,” said the doctor, “in an unexplored country! Captain Burton pushed very far to the westward, but he could not reach those celebrated mountains; he even denied their existence, strongly as it was affirmed by Speke, his companion. He pretended that they were born in the latter’s fancy; but for us, my friends, there is no further doubt possible.”
“Shall we cross them?” asked Kennedy.
“Not, if it please God. I am looking for a wind that will take me back toward the equator. I will even wait for one, if necessary, and will make the balloon like a ship that casts anchor, until favorable breezes come up.”
But the foresight of the doctor was not long in bringing its reward; for, after having tried different heights, the Victoria at length began to sail off to the northeastward with medium speed.
“We are in the right track,” said the doctor, consulting his compass, “and scarcely two hundred feet from the surface; lucky circumstances for us, enabling us, as they do, to reconnoitre these new regions. When Captain Speke set out to discover Lake Ukereoue, he ascended more to the eastward in a straight line above Kazeh.”
“Shall we keep on long in this way?” inquired the Scot.
“Perhaps. Our object is to push a point in the direction of the sources of the Nile; and we have more than six hundred miles to make before we get to the extreme limit reached by the explorers who came from the north.”
“And we shan’t set foot on the solid ground?” murmured Joe; “it’s enough to cramp a fellow’s legs!”
“Oh, yes, indeed, my good Joe,” said the doctor, reassuring him; “we have to economize our provisions, you know; and on the way, Dick, you must get us some fresh meat.”
“Whenever you like, doctor.”
“We shall also have to replenish our stock of water. Who knows but we may be carried to some of the dried-up regions? So we cannot take too many precautions.”
At noon the Victoria was at twenty-nine degrees fifteen minutes east longitude, and three degrees fifteen minutes south latitude. She passed the village of Uyofu, the last northern limit of the Unyamwezi, opposite to the Lake Ukereoue, which could still be seen.
The tribes living near to the equator seem to be a little more civilized, and are governed by absolute monarchs, whose control is an unlimited despotism. Their most compact union of power constitutes the province of Karagwah.
It was decided by the aeronauts that they would alight at the first favorable place. They found that they should have to make a prolonged halt, and take a careful inspection of the balloon: so the flame of the cylinder was moderated, and the anchors, flung out from the car, ere long began to sweep the grass of an immense prairie, that, from a certain height, looked like a shaven lawn, but the growth of which, in reality, was from seven to eight feet in height.
The balloon skimmed this tall grass without bending it, like a gigantic butterfly: not an obstacle was in sight; it was an ocean of verdure without a single breaker.
“We might proceed a long time in this style,” remarked Kennedy; “I don’t see one tree that we could approach, and I’m afraid that our hunt’s over.”
“Wait, Dick; you could not hunt anyhow in this grass, that grows higher than your head. We’ll find a favorable place presently.”
In truth, it was a charming excursion that they were making now—a veritable navigation on this green, almost transparent sea, gently undulating in the breath of the wind. The little car seemed to cleave the waves of verdure, and, from time to time, coveys of birds of magnificent plumage would rise fluttering from the tall herbage, and speed away with joyous cries. The anchors plunged into this lake of flowers, and traced a furrow that closed behind them, like the wake of a ship.
All at once a sharp shock was felt—the anchor had caught in the fissure of some rock
