The _sources_ of great rivers have often been the object of popular and even of scientific curiosity; but it is peculiar to the Niger to be interesting on account of its _termination_. Those who recollect the emotions which Park describes himself to have experienced during his former journey, on the first view of that mighty river, [Footnote: "While we were riding together, and I was anxiously looking around for the river, one of the Negroes called out, _Geo affilli_ (see the water); and looking forwards, I saw with infinite pleasure, the great object of my mission, the long sought for, majestic Niger, glittering to the morning sun, as broad as the Thames at Westminster, and flowing slowly _to the eastward_. I hastened to the brink and having drank of the water, lifted up my fervent thanks in prayer to the great Ruler of all things for having thus far crowned my endeavours with success." Park's Travels, p. 194.] will be enabled to form some idea of the enthusiasm on this subject which he intimates at the close of the foregoing Memoir, and which was now become his ruling passion. Nor can we be surprised that the question, respecting the termination of the Niger, associated as it was, with so many personal feelings, had such entire possession of Park's mind; since the subject itself, considered as a matter of geographical enquiry, is one of the most interesting that can easily be conceived. The idea of a great river, rising in the western mountains of Africa and flowing towards the centre of that vast continent; whose course in that direction is ascertained for a considerable distance, beyond which information is silent, and speculation is left at large to indulge in the wildest conjectures--has something of the _unbounded_ and _mysterious_, which powerfully attracts curiosity and takes a strong hold of the imagination. [Footnote: See Appendix, No. IV.] * * * * * A short time after Park had delivered his Memoir at the Colonial Office, he had an audience of Lord Camden, who expressed his general approbation of its contents and acquainted him with the plan of the expedition, so far as it was then determined upon. The amount of the compensation which he was to receive for this service, was likewise agreed upon and settled about the same time, with a commendable liberality on the part of Government, and entirely to Park's satisfaction; and it was also very properly stipulated that, in the event either of his dying before the completion of the service, or of his not being heard of within a given period after his setting out on the journey, a certain sum should be paid by Government as a provision for his wife and family.
