Kennedy had to fire his rifle several times at these unceremonious visitors, but the night passed without any untoward occurrence.

At five o'clock in the morning, preparations for departure commenced. Joe, with the hatchet which he had fortunately recovered, broke the elephant's tusks. The balloon, restored to liberty, sped away to the northwest with our travellers, at the rate of eighteen miles per hour.

The doctor had carefully taken his position by the altitude of the stars, during the preceding night. He knew that he was in latitude two degrees forty minutes below the equator, or at a distance of one hundred and sixty geographical miles. He swept along over many villages without heeding the cries that the appearance of the balloon excited; he took note of the conformation of places with quick sights; he passed the slopes of the Rubemhe, which are nearly as abrupt as the summits of the Ousagara, and, farther on, at Tenga, encountered the first projections of the Karagwah chains, which, in his opinion, are direct spurs of the Mountains of the Moon. So, the ancient legend which made these mountains the cradle of the Nile, came near to the truth, since they really border upon Lake Ukereoue, the conjectured reservoir of the waters of the great river.

From Kafuro, the main district of the merchants of that country, he descried, at length, on the horizon, the lake so much desired and so long sought for, of which Captain Speke caught a glimpse on the 3d of August, 1858.

Samuel Ferguson felt real emotion: he was almost in contact with one of the principal points of his expedition, and, with his spy-glass constantly raised, he kept every nook and corner of the mysterious region in sight. His gaze wandered over details that might have been thus described:

"Beneath him extended a country generally destitute of cultivation; only here and there some ravines seemed under tillage; the surface, dotted with peaks of medium height, grew flat as it approached the lake; barley-fields took the place of rice-plantations, and there, too, could be seen growing the species of plantain from which the wine of the country is drawn, and mwani, the wild plant which supplies a substitute for coffee. A collection of some fifty or more circular huts, covered with a flowering thatch, constituted the capital of the Karagwah country."

He could easily distinguish the astonished countenances of a rather fine-looking race of natives of yellowish-brown complexion. Women of incredible corpulence were dawdling about through the cultivated grounds, and the doctor greatly surprised his companions by informing them that this rotundity, which is highly esteemed in that region, was obtained by an obligatory diet of curdled milk.

At noon, the Victoria was in one degree forty-five minutes south latitude, and at one o'clock the wind was driving her directly toward the lake.

This sheet of water was christened Uyanza Victoria, or Victoria Lake, by Captain Speke. At the place now mentioned it might measure about ninety miles in breadth, and at its southern extremity the captain found a group of islets, which he named the Archipelago of Bengal. He pushed his survey as far as Muanza, on the eastern coast, where he was received by the sultan. He made a triangulation of this part of the lake, but he could not procure a boat, either to cross it or to visit the great island of Ukereoue which is very populous, is governed by three sultans, and appears to be only a promontory at low tide.

The balloon approached the lake more to the northward, to the doctor's great regret, for it had been his wish to determine its lower outlines. Its shores seemed to be thickly set with brambles and thorny plants, growing together in wild confusion, and were literally hidden, sometimes, from the gaze, by myriads of mosquitoes of a light-brown hue.
