In the midst of these occupations Park's thoughts were still turned upon Africa. Soon after the signature of the Preliminary Articles of Peace with France, in October, 1801, he received a letter from Sir Joseph Banks, acquainting him, "that in consequence of the Peace, the Association would certainly revive their project of sending a mission to Africa; in order to penetrate to, and navigate, the Niger; and he added, that in case Government should enter into the plan, Park would certainly be recommended as the person proper to be employed for carrying it into execution." But the business remained for a considerable time in suspense; nor did any specific proposal follow this communication till the autumn of the year 1803; when he received a letter addressed to him from the Office of the Colonial Secretary of State, desiring his attendance without delay. On his arrival in London he had an interview with the present Earl of Buckinghamshire, then Lord Hobart, and Secretary of State for the Colonial department, who acquainted him with the nature of an expedition to Africa, which was about to take place, and in which it was proposed, that Park should bear a principal part. To this offer he declined giving an immediate answer, requesting a short time to deliberate and consult with his friends. He returned home for this purpose about ten days afterwards. On his return to Scotland he formally consulted a few of his friends; but, in his own mind, the point was already decided. From the time of his interview with Lord Hobart, his determination was in fact taken. His imagination had been indulging itself for some years past upon the visions of discoveries which he was destined to make in the Interior of Africa; and the object of his ambition was now within his grasp. He hastily announced to Lord Hobart his acceptance of the proposal; employed a few days in settling his affairs and taking leave of his friends; and left Scotland in December, 1803, with the confident expectation of embarking in a very short time for the coast of Africa. But many delays were yet to take place previously to his final departure.
