The first part of this head is, To shew the disadvantages to _Africa_ in taking so many of its natives yearly. Before I enter upon this branch it may not be improper to mention a few observations which Mr. _Postlethwayt_ makes upon the great qualities which this country abound with. “Its situation for commerce is certainly beyond any of the other quarters of the world, for it stands in the center between the other three, and has thereby a much nearer communication with _Europe_, _Asia_, and _America_, than any other quarter has with the rest. It is wonderfully accommodated for commerce by the interposition of islands, and more particularly by the assistance of the trade winds, which render the navigation safe, easy, and constant. It is furnished with the greatest and most convenient navigable rivers, and perhaps with as many of them as any other of the chief parts of the world: Such are the _Nile_, _Nubia_, _Niger_, _Natal_, which are rivers of the first magnitude; besides these there are innumerable others, though not equal to the former, are yet very excellent streams, situated for navigation and commerce, and which by their noble courses penetrate far inland; if the _Europeans, &c._ would cultivate a human and Christian like commerce with the _Africans_, they might through these rivers become the medium of an endless beneficial commerce. The country is populous beyond credibility, the soil fruitful, the season for the greatest part mild and clement, and the air salubrious.” I must stop in the midst of this agreeable description, being afraid of leading myself into an undue length in this narrative of the beautious perfection of that rich and fruitful part of the world.
