Those communications were, at the time, most interesting and useful; they afforded at once the incentive and the direction to farther inquiry; they opened new objects to commercial enterprize, and new matter for scientific speculation, on the productions of nature, and the manners and conditions of society, in a quarter of the globe hitherto unexplored: further, they pointed out the road, and facilitated the means, of ascertaining the truth of each account, and of estimating its importance and advantages by actual visitation and experiment. Be it allowed, that the narrators spoke of what they had heard, as well as of what they had seen; let it be granted that they were mostly ignorant, credulous, or partially informed; and that, distinctively and in detail, the accuracy of their representations was little to be depended on; yet on points wherein their accounts agreed, they merited attention and regard; they _together_ opened a general view of the society, and of the country; and afforded matter of such reasonable conjecture and inference, as might warrant and direct the course of further investigation. Reflecting on these and other relations made by unenlightened men, it appears, that as the great continent of Africa, amidst its seas of sand, occasionally shews its Oasis, or fertile isle, rising in each desert; so, in analogy to the face of the country, does the blank and torpid mind of its people, display occasionally notes of intelligence and philanthropy; rich spots of genius, and partial scenes of improved social establishment. Having passed whole regions sterilized by apathy and ignorance, the result of superstitions, prejudice, and oppression, the enlightened traveller comes to a sudden view of some rich field of character, and contemplates with delight the free-born spirit and sagacity of the Tuarick of Hagara, and the ingenuity and benevolence of the Houssan. To unfold and disseminate these germs of civilization, is surely a noble task! What description of men and country can be more interesting? whither could the refinement of arts? whither could enlightened philosophy better tend, to humanize and improve? whither could the spirit of trade better direct its course? As we speculate on the projected intercourse, the noblest views open to the mind, anticipating reciprocal advantages: in the dispensation of intelligence and the arts of peace, carrying therewith complacent manners to rude and ferocious nations; and in a full compensation to the enlightened adventurers, from new materials of ingenuity and of commerce, and from new subjects of scientific inference, extending the advancement of human knowledge in all its branches.
