Before the editor finally dismisses the subject of the Congo, he may be allowed to express a hope that this distinguished river, which hitherto has been only known as one of the greatest marts of the Slave Trade, may at length be rendered conducive to objects of civilization and science; and that some use will now be made of this great inlet into Africa, for the purpose of exploring a part of that continent which as yet is entirely unknown; or, at least, of obtaining more complete and authentic information relative to the Congo itself, which must unquestionably be considered as a very curious and interesting subject of enquiry. Such an enterprise, according to the opinion of Mr. Maxwell, would not be attended with much difficulty. In a letter to Mr. Park, dated Oct. 12, 1804, alluding to the subject of the Congo, he speaks of an intention which he had formed some time prior to Park's discoveries, of exploring that river. His scheme was to carry out with him from England six supernumerary boats, well adapted for rowing and sailing; each being of such a size as to be easily carried by thirty people, and transported across several cataracts, with which the course of the river is known to be impeded. On his arrival at the coast, he meant to hire about thirty or forty black rowers, and to sail up the Congo with proper arms, provisions, and merchandize, in the month of May (the dry season south of the equator) calculating upon an absence from the coast of about ten weeks. Mr. Maxwell considered this scheme as perfectly practicable, and likely to be attended with no very great expense; but he was prevented from executing his intention by the war of 1793, which made it inconvenient and unsafe for him to encumber the deck of his vessel with supernumerary boats. IV. The fourth and last opinion respecting the termination of the Niger, is that of a German geographer, M. Reichard, which was published in the 'Ephemerides Géographiques,' at Weimar, in August, 1808, and is referred to in a respectable French work, entitled, 'Précis de la Géographie Universelle, par M. Malte-brun.' The fourth volume of this work, which appeared at Paris in the year 1813, (p. 635) represents M. Reichard's hypothesis to be, that the Niger, after reaching Wangara, takes a direction towards the south, and being joined by other rivers from that part of Africa, makes a great turn from thence towards the south-west, and pursues its course till it approaches the north eastern extremity of the gulph of Guinea, when it divides and discharges itself by different channels into the Atlantic; after having formed a great Delta, of which the Rio del Rey constitutes the eastern, and the Rio Formoso, or Benin River, the western branch.
