The city, indeed, seemed abandoned to supreme neglect; it betrayed that indifference which seems epidemic to cities that are passing away. Huge heaps of rubbish encumbered the suburbs, and, with the hill on which the marketplace stood, formed the only inequalities of the ground.
When the Victoria passed, there was some slight show of movement; drums were beaten; but the last learned man still lingering in the place had hardly time to notice the new phenomenon, for our travellers, driven onward by the wind of the desert, resumed the winding course of the river, and, ere long, Timbuktu was nothing more than one of the fleeting reminiscences of their journey.
“And now,” said the doctor, “Heaven may waft us whither it pleases!”
“Provided only that we go westward,” added Kennedy.
“Bah!” said Joe; “I wouldn’t be afraid if it was to go back to Zanzibar by the same road, or to cross the ocean to America.”
“We would first have to be able to do that, Joe!”
“And what’s wanting, doctor?”
“Gas, my boy; the ascending force of the balloon is evidently growing weaker, and we shall need all our management to make it carry us to the seacoast. I shall even have to throw over some ballast. We are too heavy.”
“That’s what comes of doing nothing, doctor; when a man lies stretched out all day long in his hammock, he gets fat and heavy. It’s a lazybones trip, this of ours, master, and when we get back everybody will find us big and stout.”
“Just like Joe,” said Kennedy; “just the ideas for him: but wait a bit! Can you tell what we may have to go through yet? We are still far from the end of our trip. Where do you expect to strike the African coast, doctor?”
“I should find it hard to answer you, Kennedy. We are at the mercy of very variable winds; but I should think myself fortunate were we to strike it between Sierra Leone and Portendick. There is a stretch of country in that quarter where we should meet with friends.”
“And it would be a pleasure to press their hands; but, are we going in the desirable direction?”
“Not any too well, Dick; not any too well! Look at the needle of the compass; we are bearing southward, and ascending the Niger toward its sources.”
“A fine chance to discover them,” said Joe, “if they were not known already. Now, couldn’t we just find others for it, on a pinch?”
“Not exactly, Joe; but don’t be alarmed: I hardly expect to go so far as that.”
At nightfall the doctor threw out the last bags of sand. The Victoria rose higher, and the blowpipe, although working at full blast, could scarcely keep her up. At that time she was sixty miles to the southward of Timbuktu, and in the morning the aeronauts awoke over the banks of the Niger, not far from Lake Debo.

Dr. Ferguson’s anxieties—Persistent movement southward—A cloud of grasshoppers—A view of Jenné—A view of Sego—Change of the wind—Joe’s regrets.
The flow of the river was, at that point, divided by large islands into narrow branches, with a very rapid current. Upon one among them stood some shepherds’ huts, but it had become impossible to take an exact observation of them, because the speed of the balloon was constantly increasing. Unfortunately, it turned still more toward the south, and in a few moments crossed Lake Debo.
Dr. Ferguson, forcing the dilation of his aerial craft to the utmost, sought for other currents of air at different heights, but in vain; and he soon gave up the attempt, which was only augmenting the waste of gas by pressing it against the well-worn tissue of the balloon.
He made no remark, but he began to feel very anxious. This persistence of the wind to head him off toward the southern part of Africa was defeating his calculations, and he no longer knew upon whom or upon what to depend. Should he not reach the English or French territories, what was to become of him in the midst of the barbarous tribes that infest the coasts of Guinea? How should he there get to a ship to take him back to England? And the actual direction of the wind was driving him along to the kingdom of Dahomey, among the most savage races, and into the power of a ruler who was in the habit of sacrificing thousands of human victims at his public orgies. There he would be lost!
On the other hand, the balloon was visibly wearing out, and the doctor felt it failing him. However, as the weather was clearing up a little, he hoped that the cessation of the rain would bring about a change in the atmospheric currents.
It was therefore a disagreeable reminder of the actual situation when Joe said aloud:
“There! the rain’s going to pour down harder than ever; and this time it will be the deluge itself, if we’re to judge by yon cloud that’s coming up!”
“What! another cloud?” asked Ferguson.
“Yes, and a famous one,” replied Kennedy.
“I never saw the like of it,” added Joe.
“I breathe freely again!” said the doctor, laying down his spyglass. “That’s not a cloud!”
“Not a cloud?” queried Joe, with surprise.
“No; it is a swarm.”
“Eh?”
“A swarm of grasshoppers!”
“That? Grasshoppers!”
“Myriads of grasshoppers, that are going to sweep over this country like a waterspout; and woe to it! for, should these insects alight, it will be laid waste.”
“That would be a sight worth beholding!”
“Wait a little, Joe. In ten minutes that cloud will have arrived where we are, and you can then judge by the aid of your own eyes.”
The doctor was right. The cloud, thick, opaque, and several miles in extent, came on with a deafening noise, casting its immense shadow over
