as any fact is shut out from the knowledge of man, he who is
in search of it will supply the deficiency by his own conclusions,
which will be more or less removed from the object of his pursuit,
according to the previous opinions which he may have formed, or to
the credit which he may have placed on the reports of others. These
remarks cannot be better illustrated, than in the case furnished by
the Joliba, the Quorra, or Niger, the termination of which river was
utterly unknown until Richard and John Lander, braving difficulties
which would have broken any other hearts than theirs, succeeded in
navigating the river until its conflux with the ocean. Since Park's
first discovery of the Joliba, every point of the compass has been
assumed for the ulterior course and termination of that river, and
however wrong subsequent discovery has proved this speculative
geography to have been, it is not to be regarded as useless. Theories
may be far short of the truth, but while they display the ingenuity
and reasoning powers of their authors, they tend to keep alive that
spirit of inquiry and thirst for knowledge which terminates in
discovery.

Various accounts of this river had been gradually collected from
different sources, which afforded grounds for fresh theories
respecting its termination. That of Reichard was the favourite, he
supposing that it assumed a southwest course, and terminated in the
gulph of Guinea. It was observed at the time, that there was neither
evidence on which such an opinion could be supported, nor any by
which it could be refuted. Discovery has proved him to be right in
respect to its ultimate disposal; but at the same time, he
participated in the general error regarding its course to Wangara.
These different opinions appeared in several publications, in which,
as might be expected, much error was mixed up with the general
correctness. That the river flowed into the sea at Funda, was the
principal and chief point that was gained; but the most extraordinary
circumstance attending this discovery, was, that no one knew where
Funda was. The only exception to these was the theory of Major
Denham, supported by Sultan Bello's information, who continued its
easterly course below Boossa, and ended it in Lake Tchad.

Such was the uncertain condition in which the course of the Niger
remained, when the happy idea occurred of sending the Messrs. Landers
to follow its course below Boossa. By this step the British
