I have left a wide field of discovery for those who come after me, especially in the geography and natural history of this country. What I have suffered should not discourage future enquirers. Their attempts will doubtless be attended with hardships and danger; but an enterprise conducted with prudence would triumph over obstacles. To ensure success, the traveller should, I think, make no sort of display; he should externally adopt the worship of Mahomet, and pass himself off for an Arab. A pretended convert would not enjoy so much liberty, and would be an object of suspicion to such distrustful people. Besides, I am of opinion that a converted christian would not be tolerated among the negro tribes. The best plan would be, I think to cross the great desert of Sahara in the character of an Arab, provided with adequate but concealed resources. After remaining for some time in the Musulman town selected by the traveller as his starting point, where he might give himself out as a merchant, to avoid suspicion, he might purchase some merchandise in that town, under the pretence of going to trade further on, carefully abstaining from all mention of the city of Timbuctoo. Let us suppose Tangiers or Arbate to be the place chosen as the point of departure; mercantile business at Fez might be alleged as an excuse for setting off. Still adopting the same pretence, the traveller might proceed from Fez to Tafilet, and thence to Timbuctoo. At Tafilet there would be no danger of speaking of Timbuctoo, for there a journey to the Soudan is an affair of frequent occurrence and it excites no attention. It would be advisable to purchase merchandise at Tafilet for the purpose of exportation. On reaching Timbuctoo, the traveller should settle there, establish a mercantile house; but he should above all things avoid appearing rich, and must make himself familiar with the customs of the country, and be very circumspect in every thing connected with religion. After remaining at Timbuctoo seventeen or eighteen months, and purchasing some Mandingo or Bambara slaves speaking the Kissour and Tooarik languages, he might procure a middle-sized well built canoe, for the conveyance of merchandise and provisions. It would be necessary to take a supply of the latter, on account of the uncertainty of being able to procure them from the people who dwell on the banks of the river. By promising the slaves their liberty, they might be easily prevailed upon to undertake the voyage, the pretended object of which would be to trade in the lower part of the river, and to purchase gum, ivory, &c. It would not be necessary to adopt all these precautions for the passage of the river above Cabra. To lull suspicion, it would be advisable to leave at Timbuctoo a certain quantity of merchandise, under the care of a confidential slave, who might have orders to dispose of it under the direction of a Moorish merchant, during his master’s absence.
