I sailed from Pointe-à-Pitre for Bordeaux, and thence returned to the Senegal. Arriving at St. Louis, at the conclusion of 1818, with scanty resources, for I had exceedingly diminished them by useless voyages, I was not to be deterred by any consideration: every thing seemed possible to my adventurous spirit, and chance seemed to second my designs. M. Adrien Partarrieu, who had been sent by Major Gray to purchase at St. Louis the goods required by the King of Bondou, was preparing to rejoin the expedition. I called upon M. Partarrieu, and proposed to accompany him without salary or engagement of any kind for the moment. He replied that he could not promise me any thing for the future, but that I was at liberty to join him if I pleased. I had soon decided—happy to seize so favourable an opportunity of visiting unknown countries and participating in an expedition of discovery. M. Partarrieu’s caravan was composed of sixty or seventy men both white and black, and thirty-two camels richly laden. We set out, on the sixth of February, 1819, from Gandiolle, a village in the kingdom of Cayor, situated at a short distance from the Senegal. The damel, or king, whom our presents had rendered favourable to us, issued orders that we should be well treated; we met every where with an hospitable reception, and in several places the people carried their generosity so far as to subsist our whole company without accepting any remuneration. On reaching the frontiers of Cayor, we came to a desert which separates it from the country of the Yolofs. It is well known that formerly these two countries belonged to the same sovereign, who governed them with the title of _boor_, or emperor, and that the damel is only an independent vassal: we experienced the same kind reception from the subjects of the boor of Yolof. It was not long before we had to regret the generous hospitality of the Yolofs. On quitting their country we entered a desert, where, for five days’ journey, we were exposed to a thousand hardships. I hope to be forgiven for entering into these details, the only ones which could have fixed themselves in the memory of a mere youth, travelling rather in quest of adventures than for the purpose of making observations.
