l a name which, according to Laing, it has at its sources—­according to Clapperton, it preserves beyond Timbuctoo, and is probably still the name of the same stream at its embouchure in the Bight of Biafra.  The Quarrama is another tributary stream which passes by Saccatoo, and falls into the Quorra above Youri, and above the point where Mungo Park was wrecked; and the line of country between this river and the Shashum, comprising the hills of Doochee, of Naroo, and of Dull, is the line of water-shed to the rivers joining the Quorra on the one hand, and those emptying themselves into the Wangara on the other.  The course given by Sultan Bello, and the information obtained by Major Denham, both pointed out a river coursing to the east, which is probably the branch followed by the Landers:  for its termination in Lake Tchad had not even the air of probability; though it is not, on the other-hand, at all improbable that other branches empty themselves into the Bight of Benin, by the rivers Formosa or Volta, according to information given to Captain Clapperton and Major Laing.

We had intended to embody some remarks upon the pretended journey of Caillie; but we find we have already occupied too much space in details necessary to make the geographical nature of the question well understood; and we shall content ourselves with remarking, that the discovery of the termination of the Quorra, or Niger, tends to throw a degree of improbability upon the narrative of that individual, which it will require much ingenuity to explain away.  It is certain that the latitude given to Timbuctoo by the editor of those travels, and upon which sufficient ridicule has already been thrown in the Edinburgh Geographical Journal, may be considered as an error entirely of the editor’s, who, by taking it upon himself, will relieve the burden of the mistake from the traveller, and thus lighten the weighty doubts which might in consequence bear upon the remainder of the details; for the situation of that city, as given by Jomard, is quite inconsistent with the situation it must be in, from the ascertained source, direction, and termination of the river.  There can be no doubt but that a portion of the labours presented to the public as the travels of Caillie are founded upon valid documents, wherever obtained, and probably most of the errors are those of the editor.  But though authorities can be found in support of the division of the Quorra into two branches; one of which, the Joliba, flows to the north-west, and the other in an almost opposite direction,—­fact which has no analogy in geography, and, what is better, no existence in nature; yet no authority can be found for placing Timbuctoo on a river flowing north from the Niger.
