Mr. Park has not only designated the route of _country_ but of _men_. He hath marked the districts of population covering the great belt of land intersecting Africa from west to east, and at the same time hath noted the distinctions of Moor and Negro, in manners, prejudices, and government. He hath thereby given to the Society information of the _viaticum_ of character and accomplishments proper and necessary to ensure the success of _their future agents_: he hath pointed out the roads to districts and cities of the greatest interest, and at the same time hath shewn the means of securing entrance and hospitable reception. The Society hath availed itself of the intelligence; and a new emissary, Mr. Horneman, hath given his lesson full effect in an expedition which is the subject of the present Volume. Of the further progress of this accomplished traveller, the Editor forbears to intimate design or suggestion. The season of mere expectation and conjecture is gone by. It were idle indeed at this period of actual discovery, to hazard surmise for future correction on experiment. At outset of the Society instituted for the purpose of exploring the Interior of Africa, it might have been proper to set forth, in glowing colours, all that was rumoured, and all that might be expected; well were general reports and ingenious inferences suited to rouze curiosity, to excite adventurous spirit, and to give a spring to the first movements and purposes of the Institution. Such incentives are no longer necessary; and knowledge actually acquired, demands, in the future display, merely accuracy and precision, as the guides to further success. The Society is confirmed in its purpose, and assured of its objects and of the means of attainment. Its travellers will not in future rush on with zealous but unadvised curiosity; or hesitate as in the dark, and on unfounded apprehensions; but, disciplined and educated, proceed with a spirit corrected and confirmed by knowledge and precaution, towards certain purposes and ends. An adventurer may yet fail; but it is presumed the adventure cannot, unless from failure of the funds and resources of the Society; which, in this great and opulent country, it would be a calumny on the generosity and patriotism of its people, for one moment to anticipate as possible. Yet let it be remembered, that the extent of our undertakings can only be commensurate with our means. Expense and charge attend our present inquiries; and even a more advantageous extension of our researches apart, demands of much beyond what our actual numbers and contributions can furnish, will be necessary to ensure the effect of national advantage, and turn to public account the successful experiment of an enlightened and patriotic, but not numerous, Association.
