On the 25th of November, 1852, all arrangements being made, Dr Barth set out on his venturesome expedition to Timbuctoo, intending to proceed first to the town of Say, on the banks of the Niger. He had parted on friendly terms with the sheikh, who sent him two fine camels as a present. He had as head servant his faithful Gatroni, who had gone to Fezzan and had lately returned, five other freemen, and two slaves, besides another personage, who acted as his broker, well accustomed to travel in Negroland; but, being an Arab, the doctor only put confidence in him as long as circumstances were propitious. He encamped, as was his custom on commencing a journey, only two miles from the city. It was the coldest night he had experienced in Negroland, the thermometer being only nine degrees above the freezing-point. On the 25th of December he arrived at Zinder, the frontier town of Bornou, built round and about masses of rock, which rose out of the ground, the picturesqueness of the place being increased by groups of date-palms. Water, which collects at short depths below the surface, fertilises a number of tobacco-fields, and gives to the vegetation around a very rich character. On the 5th of February, 1853, the party entered the town of Katseena, where he laid in a supply of articles. Here they were detained for a considerable time, as an expedition was setting out against the Fulbe, and it would have been dangerous to proceed until it was known what direction the hostile army would take. By the 25th of March, however, he was ready to continue his journey, the governor himself having arranged to accompany him for some days, as the whole country was exposed to imminent danger, and, further on, a numerous escort was to attend them.
