In fact, there is a perpetual malaria reigning throughout the country in question. Even the doctor could hope to escape its effects only by rising above the range of the miasma that exhales from this damp region whence the blazing rays of the sun pump up its poisonous vapors. Once in a while they could descry a caravan resting in a “_kraal_,” awaiting the freshness and cool of the evening to resume its route. These kraals are wide patches of cleared land, surrounded by hedges and jungles, where traders take shelter against not only the wild beasts, but also the robber tribes of the country. They could see the natives running and scattering in all directions at the sight of the _Victoria_. Kennedy was keen to get a closer look at them, but the doctor invariably held out against the idea. “The chiefs are armed with muskets,” he said, “and our balloon would be too conspicuous a mark for their bullets.” “Would a bullet-hole bring us down?” asked Joe. “Not immediately; but such a hole would soon become a large torn orifice through which our gas would escape.” “Then, let us keep at a respectful distance from yon miscreants. What must they think as they see us sailing in the air? I’m sure they must feel like worshipping us!” “Let them worship away, then,” replied the doctor, “but at a distance. There is no harm done in getting as far away from them as possible. See! the country is already changing its aspect: the villages are fewer and farther between; the mango-trees have disappeared, for their growth ceases at this latitude. The soil is becoming hilly and portends mountains not far off.” “Yes,” said Kennedy, “it seems to me that I can see some high land on this side.” “In the west—those are the nearest ranges of the Ourizara—Mount Duthumi, no doubt, behind which I hope to find shelter for the night. I’ll stir up the heat in the cylinder a little, for we must keep at an elevation of five or six hundred feet.” “That was a grand idea of yours, sir,” said Joe. “It’s mighty easy to manage it; you turn a cock, and the thing’s done.” “Ah! here we are more at our ease,” said the sportsman, as the balloon ascended; “the reflection of the sun on those red sands was getting to be insupportable.” “What splendid trees!” cried Joe. “They’re quite natural, but they are very fine! Why a dozen of them would make a forest!”
