sulphuretted hydrogen emanations, which Captain Burton mentions, could be distinctly smelt.
“According to his statement, and I think he’s right,” said the doctor, “one could readily believe that there is a corpse hidden behind every thicket.”
“An ugly country this!” sighed Joe; “and it seems to me that Mr. Kennedy is none the better for having passed the night in it.”
“To tell the truth, I have quite a high fever,” said the sportsman.
“There’s nothing remarkable about that, my dear Dick, for we are in one of the most unhealthy regions in Africa; but we shall not remain here long; so let’s be off.”
Thanks to a skilful manoeuvre achieved by Joe, the anchor was disengaged, and Joe reascended to the car by means of the ladder. The doctor vigorously dilated the gas, and the Victoria resumed her flight, driven along by a spanking breeze.
Only a few scattered huts could be seen through the pestilential mists; but the appearance of the country soon changed, for it often happens in Africa that some of the unhealthiest districts lie close beside others that are perfectly salubrious.
Kennedy was visibly suffering, and the fever was mastering his vigorous constitution.
“It won’t do to fall ill, though,” he grumbled; and so saying, he wrapped himself in a blanket, and lay down under the awning.
“A little patience, Dick, and you’ll soon get over this,” said the doctor.
“Get over it! Egad, Samuel, if you’ve any drug in your travelling-chest that will set me on my feet again, bring it without delay. I’ll swallow it with my eyes shut!”
“Oh, I can do better than that, friend Dick; for I can give you a febrifuge that won’t cost any thing.”
“And how will you do that?”
“Very easily. I am simply going to take you up above these clouds that are now deluging us, and remove you from this pestilential atmosphere. I ask for only ten minutes, in order to dilate the hydrogen.”
The ten minutes had scarcely elapsed ere the travellers were beyond the rainy belt of country.
“Wait a little, now, Dick, and you’ll begin to feel the effect of pure air and sunshine.”
“There’s a cure for you!” said Joe; “why, it’s wonderful!”
“No, it’s merely natural.”
“Oh! natural; yes, no doubt of that!”
“I bring Dick into good air, as the doctors do, every day, in Europe, or, as I would send a patient at Martinique to the Pitons, a lofty mountain on that island, to get clear of the yellow fever.”
“Ah! by Jove, this balloon is a paradise!” exclaimed Kennedy, feeling much better already.
“It leads to it, anyhow!” replied Joe, quite gravely.
It was a curious spectacle—that mass of clouds piled up, at the moment, away below them! The vapors rolled over each other, and mingled together in confused masses of superb brilliance, as they reflected the rays of the sun. The Victoria had attained an altitude of four thousand feet, and the thermometer indicated a certain diminution of temperature. The land below could no longer be seen. Fifty miles away to the westward, Mount Rubeho raised its sparkling crest, marking the limit of the Ugogo country in east longitude thirty-six degrees twenty minutes. The wind was blowing at the rate of twenty miles an hour, but the aeronauts felt nothing of this increased speed. They observed no jar, and had scarcely any sense of motion at all.
Three hours later, the doctor’s prediction was fully verified. Kennedy no longer felt a single shiver of the fever, but partook of some breakfast with an excellent appetite.
That beats sulphate of quinine!” said the energetic Scot, with hearty emphasis and much satisfaction.
“Positively,” said Joe, “this is where I’ll have to retire to when I get old!”
About ten o’clock in the morning the atmosphere cleared up, the clouds parted, and the country beneath could again be seen, the Victoria meanwhile rapidly descending. Dr. Ferguson was in search of a current that would carry him more to the northeast, and he found it about six hundred feet from the ground. The country was becoming more broken, and even mountainous. The Zungomoro district was fading out of sight in the east with the last cocoanut-trees of that latitude.
Ere long, the crests of a mountain-range assumed a more decided prominence. A few peaks rose here and there, and it became necessary to keep a sharp lookout for the pointed cones that seemed to spring up every moment.
“We’re right among the breakers!” said Kennedy.
“Keep cool, Dick. We shan’t touch them,” was the doctor’s quiet answer.
“It’s a jolly way to travel, anyhow!” said Joe, with his usual flow of spirits.
In fact, the doctor managed his balloon with wondrous dexterity.
“Now, if we had been compelled to go afoot over that drenched soil,” said he, “we should still be dragging along in a pestilential mire. Since our departure from Zanzibar, half our beasts of burden would have died with fatigue. We should be looking like ghosts ourselves, and despair would be seizing on our hearts. We should be in continual squabbles with our guides and porters, and completely exposed to their unbridled brutality. During the daytime, a damp, penetrating, unendurable humidity! At night, a cold frequently intolerable, and the stings of a kind of fly whose bite pierces the thickest cloth, and drives the victim crazy! All this, too, without saying any thing about wild beasts and ferocious native tribes!”
“I move that we don’t try it!” said Joe, in his droll way.
“I exaggerate nothing,” continued Ferguson, “for, upon reading the narratives of such travellers as have had the hardihood to venture into these regions, your eyes would fill with tears.”
About eleven o’clock they were passing over the basin of Imenge, and the tribes scattered over the adjacent hills were impotently menacing the Victoria with their weapons. Finally, she sped along as far as the last undulations of the country which precede Rubeho. These form the last and loftiest chain of the mountains of Usagara.
The aeronauts took careful and complete note of the orographic conformation of the country. The three ramifications mentioned, of which the Duthumi forms the first link, are separated by immense longitudinal plains. These elevated summits consist of rounded cones, between which the soil is bestrewn with erratic blocks of stone and gravelly bowlders. The most abrupt declivity of these mountains confronts the Zanzibar coast, but the western slopes are merely inclined planes. The depressions in the soil are covered with a black, rich loam, on which there is a vigorous vegetation. Various watercourses filter through, toward the east, and work their way onward to flow into the Kingani, in the midst of gigantic clumps of sycamore, tamarind, calabash, and palmyra trees.
“Attention!” said Dr. Ferguson. “We are approaching Rubeho, the name of which signifies, in the language of the country, the ‘Passage of the Winds,’ and we would do well to double its jagged pinnacles at a certain height. If my chart be exact, we are going to ascend to an elevation
