INTRODUCTION.

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,
