Rene Caillie, a French traveller, bora at Mauze in 1799, died May 28, 1838. When only 16 years old he set out on a voyage to Senegal, and afterward accompanied a caravan to Bondoo, where he joined an English exploring expedition. This having been thwarted, he returned to France, and in 1824 set out again for Senegal, and made preparations to penetrate into the interior of Soodan. He left Kakondy April 19, 1827, and after many hardships and detention by illness of five months reached Jenne, on the Niger, March 11, 1828. A month's sail on the Niger brought him to Timbuctoo, where he spent 14 days, and then, joining a caravan, he made a journey across the desert to Fez and Morocco, returning to France in the latter part of 1828. The geographical society of Paris awarded him a prize of 10,000 francs, which had been offered to the first traveller who should visit Timbuctoo, and the annual prize of 1,000 francs for the most important discovery. He also received a pension and the order of the legion of honor.

His Journal d'un voyage d Tombouctou et d Yenne, dans VAfrique centrale, with geographical notes by M. Jomard, was published at the cost of the French government (3 vols. 8vo, Paris, 1830). He retired to a small estate which he had purchased in the department of Cha-rente-Inferieure, and was projecting another journey in Africa at the time of his death.
