CHAPTER XXVII.

FROM LAKE ALBERT TO MURCHISON FALLS.

Ten miles from Magungo the river suddenly narrowed, till it was but two

hundred and fifty yards broad. The great level tracks of rush banks

gradually disappeared as they entered a channel shut in by high banks on

either side. The hills here were heavily timbered.

Even here the current was so sluggish as to indicate no perceptible

stream. A heavy fog soon covered the river. Gradually it lifted. As

Baker watched it slowly rise from the water, he noticed the little,

floating, green water plants perceptibly moving to the west. Looking

more closely, he saw that their progress, though slow, was certainly

towards Albert Nyanza.

[Illustration: CROCODILES ON THE BANKS OF THE NILE.]

They were about eighteen miles from Magungo when they perceived this

very slight current in the river. Proceeding on their journey, they

found the river gradually narrowing to a width of but one hundred and

eighty yards. As they ceased paddling the roar of the water could be

distinctly heard. After two hours of hard pulling, during which the

velocity of the water was noticeably increasing and the roar of the fall

became extremely loud, they reached a few deserted fishing huts. These

were situated at a convenient little bend in the river.

At this point crocodiles were noticed in immense numbers. They lay

closely packed together, like timber logs in a lumber region. Upon one

bank twenty-seven of the ugly reptiles lay basking in the sunlight.

Every nook and turn in the bank disclosed crowds of them lurking in the

stream, their hideous jaws just showing on the surface of the water.

The banks on either side, which had gradually been growing steeper, now

became decidedly bolder and more rugged. The roar of the fall grew more

fearful, and as they rounded the corner of the stream a magnificent view

burst upon them. On either side of the river beautifully wooded cliffs

rose precipitously to a height of some three hundred feet. Here and

there picturesque rocks jutted out from among the green foliage. The

river, abruptly contracted from its grand proportions into a narrow

stream, rushed madly through a gap cleft in the rock before them.

Through a gorge scarcely fifty feet in width it poured its waters with a

furious rush and roar, as it plunged with one gigantic leap into a dark

abyss lying one hundred and twenty feet below.

To quote from Baker's journal: "The fall of the water was snow-white,

which had a superb effect as it contrasted with the dark cliffs that

walled the river, while the graceful palms of the tropics and wild

plantains perfected the beauty of the view. This was the greatest

waterfall of the Nile, and in honor of the distinguished president of

the Royal Geographical Society, I named it the Murchison Falls, as the

most important object throughout the entire course of the river."

The canoes of the little party endeavored to approach the falls, but

when about three hundred yards from them the strong current and the

terrific whirlpools prevented any nearer view.

At their left a sand bank was literally covered with crocodiles. They

seemed to have no fear of the canoe till it approached within twenty

yards of them, when they slowly and lazily crept out of the water. A

huge hippopotamus charged the canoe, and struck the bottom of it with

such tremendous force as nearly to throw the crew out of it. Proud of

his achievement, the ugly monster raised his head to look at his strange

enemy, then sank rapidly in the stream.

The canoe now drifted rapidly down to a landing at a small deserted

fishing village, and the little party bade adieu to the lake and river

which had interested them so much in Central Africa.

If we look at the map of Africa, we shall find that the great lakes,

which form such an important physical feature of the continent, are

located chiefly in the southern and eastern sections of it, but are

distributed overall the great drainage systems. Let us take a little

review of the lake system.

Both lakes of the Nile basin, the Victoria and Albert Nyanza lakes, are

really great fresh-water seas.

If the present estimate of this great extent should ultimately prove to

be fairly correct, they are the rivals even of the great American lakes

in being the greatest expanse of fresh water on the face of the globe.

In 1889, a great lake lying three hundred miles northeast of the

Victoria Nyanza was discovered. It has been named Lake Rudolf. It is

about one hundred and sixty two miles long and over twenty miles wide.

The principal lakes of the Congo basin are Lake Bangweolo, or Bemba, one

hundred and fifty miles long from east to west, and Lake Moero, having a

length of sixty miles. There are several lakes of this basin still

unvisited. They are said to be of vast extent and to lie two thousand

feet above the level of the sea.

Lake Nyassa belongs to the Zambesi basin. It covers an area of nearly

nine thousand miles in this great river basin. Lake Shirwa, on the

plateau southeast of Lake Nyassa, is enclosed by mountains. It has an

elevation of two thousand feet above the sea. Its water is brackish and

has no outlet. Lake Tanganyika occupies an area of more than ten

thousand square miles. A broad channel unites it with Lake Liemba, in

the south. No outlet was for many years discovered for Tanganyika. It is

probably a continental lake; for its waters are not perfectly fresh, and

its drainage is very small.

Lake Tchad is the greatest lake of the continental system of North

Africa. It consists of a shallow lagoon of very variable extent.

Numerous islands dot its surface. Its waters are fresh and clear, and

the overflow is carried off by the Bahr-el-Gazal to the northeast. Lake

N'gami is in the southern continental system. It corresponds to Lake

Tchad of the northern system. It is a shallow, reedy lagoon. Its extent

varies according to the seasons. Its surplus water is carried by the

Zuga River off to the eastward. Within the areas of continental

drainage, salt lakes occur frequently. Assal Lake, in Abyssinia, is the

most remarkable of these salt lakes.
