The supposition, mentioned in the text (p. lxviii), that the Niger terminates in the River Congo, or, as it is sometimes called, the Zaire, is entirely a recent conjecture, adopted by Park in consequence of the information and suggestions of Mr. Maxwell, an experienced African trader, who appears from his letters to have been a man of observation and intelligence. The principal arguments in support of the opinion are shortly and clearly given in the memoir addressed by Park to Lord Camden; but the subject will receive additional elucidation from Mr. Maxwell's own statement, and especially from his striking description of the river Congo, the vast magnitude of which is little known, and has not sufficiently attracted the attention of geographical writers. The following passage is extracted from a letter, dated Prior's Lynn, near Longtown, July 20, 1804, addressed by Mr. Maxwell to William Keir, of Milnholm, Esq., a friend of Park, to whom the letter was communicated by Mr. Maxwell's desire. "Before ever the Niger came to be the topic of conversation, it struck me, that the Congo drew its source far to the northward, from the floods commencing long before any rains take place south of the equator; since it begins to swell perceptibly about the latter end of October, and no heavy rains set in before December: and about the end of January the river must be supposed at its highest. At no time, however, can the rains to the southward of the Line be compared with those in the Bight of Guinea, where ships are obliged to have a house erected over them during these months.
