BURTON IN A DUG-OUT ON LAKE TANGANYIKA.
After a drawing by Burton.

As the two men tramped on, the streams began to drain to the west and the land grew more fertile, till one hundred and fifty miles from Kaze they began to ascend the slope of mountains overhanging the northern half of Lake Tanganyika. "This mountain mass," says Speke, "I consider to be the True Mountains of the Moon." From the top of the mountains the lovely Tanganyika Lake could be seen in all its glory by Burton. But to Speke it was a mere mist. The glare of the sun and oft-repeated fever had begun to tell on him, and a kind of inflammation had produced almost total blindness. But they had reached the lake and they felt sure they had found the source of the Nile. It was a great day when Speke crossed the lake in a long canoe hollowed out of the trunk of a tree and manned by twenty native savages under the command of a captain in a "goatskin uniform." On the far side they encamped on the opposite shore, Speke being the first white man to cross the lake.

Having retired to his hut for the night, Speke proceeded to light a candle and arrange his baggage, when to his horror he found the whole interior swarming with black beetles. Tired of trying to brush them away, he put out his light and, though they crawled up his sleeves and down his back, he fell asleep. Suddenly he woke to find one crawling into his ear, and in spite of his frantic efforts it crept in farther and farther till it reached the drum, which caused the tired explorer intense agony. Inflammation ensued, his face became drawn, he could with difficulty swallow a little broth, and he was quite deaf. He returned across the lake to find his companion, Burton, still very ill and unfit for further exploration.

So Speke, although still suffering from his ear, started off again, leaving Burton behind, to find the great northern lake spoken of as the sea of Ukerewe, where the Arabs traded largely in ivory. There was a great empire beyond the lake, they told him, called Uganda.

But it was July 1858 when the caravan was ready to start from Kaze. Speke himself carried Burton's large elephant gun. "I commenced the journey," he says, "at 6 p.m., as soon as the two donkeys I took with me to ride were caught and saddled. It was a dreary beginning. The escort who accompanied me were sullen in their manner and walked with heavy gait and downcast countenance. The nature of the track increased the general gloom.

"For several weeks the caravan moved forward, till on 3rd August it began to wind up a long but gradually inclined hill, until it reached its summit, when the vast expanse of the pale blue waters of the Nyanza burst suddenly upon my eyes! It was early morning. The distant sea-line of the north horizon was defined in the calm atmosphere, but I could get no idea of the breadth of the lake, as an archipelago of islands, each consisting of a single hill rising to a height of two or three hundred feet above the water, intersected the line of vision to the left. A sheet of water extended far away to the eastward. The view was one which even in a well-known country would have arrested the traveller by its peaceful beauty. But the pleasure of the mere view vanished in the presence of those more intense emotions called up by the geographical importance of the scene before me. I no longer felt any doubt that the lake at my feet gave birth to that interesting river (Nile), the source of which has been the subject of so much speculation and the object of so many explorers. This is a far more extensive lake than Tanganyika; it is so broad that you could not see across it, and so long that nobody knew its length. This magnificent sheet of water I have ventured to name Victoria after our gracious sovereign."

BURTON AND HIS COMPANIONS ON THE MARCH TO THE VICTORIA NYANZA.
From a humorous sketch by Burton.

Speke returned to Kaze after his six weeks' eventful journey, having tramped no less than four hundred and fifty-two miles. He received a warm welcome from Burton, who had been very uneasy about his safety, for rumours of civil war had reached him. "I laughed over the matter," says Speke, "but expressed my regret that he did not accompany me, as I felt quite certain in my mind I had discovered the source of the Nile."
