Many are the acquisitions which geography has made since the boundaries of commerce have been extended, and the spirit of enterprise has carried our adventurous countrymen into countries which had never yet been indented by a European foot; and which, in the great map of the world, appeared as barren and uninhabitable places, destitute of all resources from which the traveller could derive a subsistence.

It must, however, on the other hand, be admitted, that design has frequently had little to do in the discovery of those countries, however well it may have been conceived, and however great the perseverance may have been, which was exhibited in the pursuit.

The discovery of America was, indeed, a splendid example of an enlightened conception, and an undaunted heroism, crowned with the most complete success; and the laudable and unabated ardour which this country, in despite of the most appalling obstacles, has persisted in solving the great geographical problem of the Course and Termination of the Niger, may be placed second in rank to the discovery of America.
As long 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.
