The attention of Park was naturally drawn to this subject, in consequence of his connection with Sir Joseph Banks, who had received him with great kindness and cordiality on his return from the East Indies, and with whom he was now in habits of frequent intercourse. Sir Joseph Banks was one of the most active and leading members of the African Association, and with his accustomed zeal for the promotion of scientific discovery, was earnest in his endeavours to find out a proper person to undertake the mission in search of the Niger. There was nothing in Park's previous studies which had particularly led him towards geographical pursuits; but he had a general passion for travelling; he was in the full vigour of life; his constitution had been in some degree inured to hot climates; he saw the opportunities which a new country would afford of indulging his taste for Natural History: nor was he insensible to the distinction which was likely to result from any great discoveries in African geography. These considerations determined him. Having fully informed himself as to what was expected by the Association, he eagerly offered himself for the service; and after some previous enquiry into his qualifications, the offer was readily accepted. Between the time of Park's return from India in 1793, and his departure to Africa, an interval elapsed of about two years. During the whole of this period (with the exception of a short visit to Scotland in 1794), he appears to have resided in London or its neighbourhood; being engaged partly in his favourite studies, or in literary or scientific society; but principally in acquiring the knowledge and making the preparations, which were requisite for his great undertaking. Having received his final instructions from the African Association, he set sail from Portsmouth on the 22d of May, 1795, on board the Endeavour, an African trader, bound for the Gambia, where he arrived on the 21st of the following month. It is not the intention of this narrative to follow him through the details of this journey, a full account of which was afterwards published by Park, and is familiar to every reader. But it may be useful to mention the material dates and some of the principal transactions. Having landed on the 21st of June at Jillifree, a small town near the mouth of the River Gambia; he proceeded shortly afterwards to Pisania, a British factory about 200 miles up the same river, where he arrived on the 5th of July, and was most hospitably received by Dr. Laidley, a gentleman who had resided many years at that settlement. He remained at Dr. Laidley's house for several months, in order to learn the Mandingo language, which is in general use throughout that part of Africa, and also to collect information concerning the countries he intended to visit. During two of these months he was confined by a severe fever, caught by imprudently exposing himself during the rainy season.
