Major Denham and Dr Oudney were anxious to visit Birnie, the old capital of Bornou, and the sheikh left one of his chief slaves, Omar Gana, to act as their guide. Thence they were to proceed to Kabshary, there to await his arrival. They set out with five camels and four servants, making two marches each day, from ten to fourteen miles, morning and evening. The country round Kouka is uninteresting and flat, thickly covered with acacias. The ruins of old Birnie, which they visited, convinced them of the power of its former sultan. The city, though now in ruins, covered a space of five or six square miles. The walls, in many places standing, consisted of large masses of red brickwork, three or four feet in thickness, and six to eight in height. Besides destroying the capital, the Felatahs had razed to the ground upwards of thirty large towns during their inroads. The whole country which they passed after proceeding some way had become a complete desert, having been abandoned since the Felatahs commenced their inroads, and wild animals of all descriptions abounded in great numbers. They heard that Kabshary had been attacked by the Munga people and burned; and news came that the Munga horse were reconnoitring all round them, and had murdered some men proceeding to join the sheikh. One of the means the people had taken to defend themselves against the invaders, had been to dig deep holes, at the bottom of which sharp-pointed stakes were fixed, the pits being then carefully covered over with branches and grass, so as completely to conceal them. Similar pitfalls are used in many parts of Africa for entrapping the giraffe and other wild animals. The major's servant, Columbus, and his mule not making their appearance, he was searching for him, when he found that the animal had fallen into one of these pits, the black having by a violent exertion of strength saved himself. The poor mule was found sticking on four stakes, with her knees dreadfully torn by struggling. She was, however, got out alive. Escaping from various dangers, they joined the sheikh on the banks of a large piece of water called Dummasak. Hearing that a caravan had arrived at Kouka from Fezzan, they were anxious to return to the capital. They sent word to the sheikh, but their communication was not delivered, and, before they could see him, he and his troops had moved off. They were, however, on their way to Kouka, when Omar Gana overtook them, entreating them to return to the sheikh, who, angry at their having gone, had struck him from his horse, and directed him to bring them to the army without delay. They had nothing to do but to obey.
