in the scale of the African travellers.  It is, however, curious to observe how even the best collectors of oral information in that country, have failed in arriving at the truth, as to the origin, cause, and termination of the rivers.  Edrisi, Abulfida, Leo Africanus,[Footnote] Delile, and Bruce, all come to the determination that the Quorra flowed from east to west.  Burckhardt, whose oral inquiries on Bornou, have proved generally correct, concluded that the Shary flowed from N.E. to S.W., and Lyon, though particularly successful in his information on the countries not visited by him, was induced to confound the Shary of Bornou with the Tchadda or Yen, and like Sultan Bello, to carry the Quorra, after passing Youri and Funda, into the Lake Tchadda, and thence into Egypt.  The most intelligent natives are confused, when questioned on the subject of rivers, while the majority, unable to understand the object or utility of such enquiries, can neither inform the traveller whether two streams are different rivers or part of the same; where any river rises, or whither it flows, and appear often to believe that all the lakes and streams of Africa, are parts of one and the same water.  It is not surprising, therefore, that ancients as well as moderns have obtained the knowledge of a large river flowing to the east, should have supposed that it was a branch of the Nile of Egypt, or that when the existence of a great lake, in the direction of the known portion of its stream, became known, the opinion should have followed, that the river terminated in that lake, or that it was discharged through the lake into the Nile.  Such, consequently have been the prevalent notions in all ages, even amongst the most intelligent foreigners, as well as the higher class of natives, from Herodotus, Etearchus, and Juba, to Ibn, Batuta, and Bello of Soccatoo.

[Footnote:  It is supposed by W. Martin Leake, Esq.  Vice President of the Geographical Society, that Leo Africanus actually reached Timbuctoo.  The narrative of Adams places the matter at rest, that Leo never did reach that famous city.  Mr. Leake says, that Leo was very young at the time, and, therefore that his memory probably failed him, when he came to describe the city, which was many years after his return.]

Considering these circumstances, it will hardly be contended that the late discovery of the Landers, has made any alteration in the nature of the question, as to the identity of the Quorra and Nigir; the sudden bend of the river to the southward, through a country, which has been equally unknown to the ancients and moderns, having always left the best informed of them in ignorance of any part of the river, except that of which the course was northerly or easterly.  If then, there be sufficient reason for the belief, that these latter portions were known to the, ancients, we have only to suppose them to have had some such imperfect knowledge of the interior of North Africa, as we ourselves had attained previously to the expedition
