THE LANDERS VOYAGE AND DISCOVERIES ON THE NIGER.

The travellers, in embarking on the Atlantic, had solved the greatest

problem in African, and even in modern geography;--one which had

exercised the ingenuity and conjecture of so many learned inquirers,

and in the efforts to solve which so many brave and distinguished

adventurers had perished. This discovery divested the Niger of that

singular and mysterious character, which had been one chief cause of

the interest that it had excited--when seen rolling its ample flood

_from_ the sea towards vast unknown regions in the interior. The

circuit by which it reaches the Atlantic assimilates its character

to that of ordinary rivers, without any much more remarkable windings

than are found in others of similar length. It displays, however, a

magnitude considerably greater than had been suggested by any former

observation.

We can now trace very distinctly, the entire line of this great river.

Its source, though not actually visited, seems ascertained by Laing

to exist in the high country of Kissi, about 200 miles in the interior

from Sierra Leone. Thence it rolls through Foota Jallo and Kankan,

where Caillie describes himself to have found it already a rapid and

considerable stream. At Bammakoo, having received the tributary from

Sankari in Manding, which Park mistook for the main river, it begins

its course over the fine plain of Bambarra, where it forms a noble

stream; and in passing Sego, the capital, has been considered

as equalling the Thames at Westminster. Thence it pursues a

north-westerly course, and flowing through the lake Dibbie, reaches

Timbuctoo. Its course from that city to Youri has not yet been

delineated; but the fact that Park navigated down from one place to

the other, fully establishes the continuity. During this reach the

Niger makes a great change of direction from north-east to almost

due south. From Youri to the sea, it was navigated by the present

travellers, and was found following generally a southern direction,

though making in one part a rapid bend to the east, whence it

gradually returns. If we measure two distances, one from the source

to Timbuctoo, and the other from that city to the sea, we shall have

nearly 2,000 miles, which may be considered as the direct course;

and the various windings must raise the whole line of the stream to

upwards of 3,000 miles. For several hundred miles of its lower course,

it forms a broad and magnificent expanse, resembling an inland sea.

The Niger must after all yield very considerably to the Missouri and

Orellana, those stupendous rivers of the new world. But it appears at

least as great as any of those which water the old continents. There

can rank with it only the Nile, and the Yangtse-kiang, or Great

River of China. But the upper course of neither is yet very fully

ascertained; and the Nile can compete only in length of course, not in

the magnitude of its stream, or the fertility of the regions which it

waters. There is one feature in which the Niger may defy competition

from any river, either of the old or new world. This is in the

grandeur of its Delta. Along the whole coast, from the river of

Formosa or Benin to that of Old Calabar, about 300 miles in length,

there open into the Atlantic its successive estuaries, which

navigators have scarcely been able to number. Taking this coast as

the base of the triangle or Delta, and its vertex at Kirree, about 170

miles inland, where the Formosa branch separates, we have a space of

upwards of 25,000 square miles, equal to the half of England. Had

this Delta, like that of the Nile, been subject only to temporary

inundations, leaving behind a layer of fertilizing slime, it would

have formed the most fruitful region on earth, and might have been

almost the granary of a continent. But, unfortunately, the Niger rolls

down its waters in such excessive abundance, as to convert the whole

into a huge and dreary swamp, covered with dense forests of mangrove,

and other trees of spreading and luxuriant foliage. The equatorial

sun, with its fiercest rays, cannot penetrate these dark recesses; it

only exhales from them pestilential vapours, which render this coast

the theatre of more fatal epidemic diseases than any other, even of

Western Africa. That human industry will one day level these forests,

drain these swamps, and cover this soil with luxuriant harvests, we

may confidently anticipate; but many ages must probably elapse before

man, in Africa, can achieve such a victory over nature.

The Niger, besides its own ample stream, has a number of tributaries,

equal perhaps in magnitude and importance to those of any other

river on the globe; with the exception of the united streams of the

Mississippi and Missouri. At no great distance above the point where

the Delta commences, the Tshadda, nearly equal in magnitude to itself,

enters it; after watering large and fruitful kingdoms, of which the

names only, and of these but a very few, have reached us. On this

river an extensive commerce and active navigation is said to prevail;

the existence of which is further confirmed by the great importance

attached to Funda, and other cities situated at or near the junction.

It would have been deeply interesting, and have given a new importance

to the river communications of Africa, could we have believed, what

was positively asserted by very credible witnesses, that vessels

by its channel sailed to and from the lake Tchad, and thus held

intercourse with the kingdoms of Loggun and Bornou. It seems certain

that the names Tshadda, Shary, and Tchad, are one and the same. But

the identity of the two first as rivers is what we are precluded from

all possibility of believing, by the circumstance that the Shary of

Loggun and Bornou, which Major Denham saw and sailed upon, was found

by him falling _into_ lake Tchad, while the Tshadda of Lander fell

_into_ the Niger; consequently they are distinct streams, flowing in

opposite directions. It is very probable indeed that their fountains

may be in the same mountain chain, and at no great distance; and even

that some of their branches may approach very near, so that merchants

may, by an easy portage, convey commodities between them. Nay, it

is not quite impossible that they may be united by some connecting

channel, as the Amazons and the Oronooka are; but this seems scarcely

probable.

At no great distance above the Tshadda, enters the Coodonia, a smaller

river, but which Lander had seen flowing through a very fertile and

highly cultivated country. Considerably higher is the Cubbie, a large

stream from the country and city of that name; and higher still the

Quarrama, which has passed by Zirmie and Sackatoo. Between this point

and Timbuctoo, we have no means of knowing whether any or what rivers

fall into the Niger. The tributary which passes that city is of

no great importance; but at the eastern boundary of Bambarra, Park

describes the influx from the south of two great streams, the Maniana

and Nimma; and it seems very doubtful if Caillie was not mistaken

in supposing the latter to be a mere branch of the Niger. The higher

tributaries, descending from the mountains, swell the stream, without

themselves affording any important navigation.--_Edinburgh Review._
