Jenneh, two miles and a half in circumference, is surrounded by a mud wall ten feet high. The houses, built of bricks baked in the sun, are as large as those of European peasants. They have all terraces, but no outer windows. Numbers of foreigners frequent Jenneh. The inhabitants, as many as eight or ten thousand, are very industrious and intelligent. They hire out their slaves, and also employ them in various handicrafts. The Moors, however, monopolize the more important commerce. Not a day passes that they do not despatch huge boats laden with rice, millet, cotton, honey, vegetable butter, and other native products. In spite of this great commercial movement, the prosperity of Jenneh was threatened. Sego Ahmadou, chief of the country, impelled by bigoted zeal, made fierce war upon the Bambarras of Sego, whom he wished to rally round the standard of the Prophet. This struggle did a great deal of harm to the trade of Jenneh, for it interrupted intercourse with Yamina, Sansanding, Bamakou, and Boureh, which were the chief marts for its produce. The women of Jenneh would not be true to their sex if they did not show some marks of coquetry. Those who aim at fashion pass a ring or a glass ornament through the nostrils, whilst their poorer sisters content themselves with a bit of pink silk. During Caillie's long stay at Jenneh, he was loaded with kindness and attentions by the Moors, to whom he had told the fabulous tale about his birth in Egypt, and abduction by the army of occupation. On the 23rd March, the traveller embarked on the Niger for Timbuctoo, on which the sheriff, won over by the gift of an umbrella, had obtained a passage for him. He carried with him letters of introduction to the chief persons in Timbuctoo. Caillie now passed in succession the pretty villages of Kera, Taguetia, Sankha-Guibila, Diebeh, and Isaca, near to which the river is joined by an important branch, which makes a great bend beyond Sego, catching sight also of Wandacora, Wanga, Corocoila, and Cona, finally reaching, on the 2nd of April, the mouth of the important Lake Debo. "Land," says Caillie, "is visible on every side of this lake except on the west, where it widens out like a vast inland sea. Following its northern coast in a west-north-west direction for a distance of fifteen miles, you leave on the left a tongue of level ground, which runs several miles to the south, seeming to bar the passage of the lake, and form a kind of strait. Beyond this barrier the lake stretches away out of sight in the west. The barrier I have just described cuts Lake Debo into two parts, the upper and lower. That navigable to boats contains three islands, and is very wide; it stretches away a short distance on the east, and is supplemented by an immense number of huge marshes."
