"The letter which I wrote on the subject of the publication of your travels in Africa, is perfectly at your service to make any use of, which you may think proper. No measure can be more satisfactory and agreeable to myself, than that which may most fully render justice to your high and well earned reputation in every point of view." APPENDIX. No. IV. The question regarding the termination of the Niger is one of the most doubtful and obscure in modern geography, and in the present defective state of our information with regard to the interior of Africa, seems hardly to admit of a clear and satisfactory solution. Of the difficulties with which the subject is attended, some judgment may be formed from the various and even opposite opinions which have been maintained relative to the course of the Niger, since Park's discoveries have ascertained that it flows from west to east. As the enquiry is somewhat curious, a summary view of these different opinions, and of the principal arguments by which they are supported, may not be uninteresting to the readers of Park's life. To investigate the question with the accuracy and minuteness which it deserves, would not only very far exceed the limits of a note, but would require much more information upon this subject than the editor possesses, united with some previous habits of geographical disquisition. I. According to the oldest of these opinions, and that which is supported by the greatest authorities (being the opinion not only of some of the principal Geographers of antiquity, but of D'Anville and Rennell among the moderns), it is supposed, that the Niger has an inland termination somewhere in the eastern part of Africa, probably in Wangara or Ghana: and that it is partly discharged into inland lakes, which have no communication with the sea, and partly spread over a wide extent of level country, and lost in sands or evaporated by the heat of the sun.
