Here, guided by some Gallas, he worked his way up the Blue Nile to the three fountains, which he declared to be the true sources of the Nile, and identified with the three mysterious lakes in the old maps. From there he worked his way down the Nile, reaching Cairo in 1773. Of course what he had discovered was merely the source of the Blue Nile, and even this had been previously visited by a Portuguese traveller named Payz. But the interesting adventures which he experienced, and the interesting style in which he told them, aroused universal attention, which was perhaps increased by the fact that his journey was undertaken purely from love of adventure and discovery. The year 1768 is distinguished by the two journeys of James Cook and James Bruce, both of them expressly for purposes of geographical discovery, and thus inaugurating the era of what may be called scientific exploration. Ten years later an association was formed named the African Association, expressly intended to explore the unknown parts of Africa, and the first geographical society called into existence. In 1795 MUNGO PARK was despatched by the Association to the west coast. He started from the Gambia, and after many adventures, in which he was captured by the Moors, arrived at the banks of the Niger, which he traced along its middle course, but failed to reach as far as Timbuctoo. He made a second attempt in 1805, hoping by sailing down the Niger to prove its identity with the river known at its mouth as the Congo; but he was forced to return, and died at Boussa, without having determined the remaining course of the Niger.
Attention was thus drawn to the existence of the mysterious city of Timbuctoo, of which Mungo Park had brought back curious rumours on his return from his first journey. This was visited in 1811 by a British seaman named Adams, who had been wrecked on the Moorish coast, and taken as a slave by the Moors across to Timbuctoo. He was ultimately ransomed by the British consul at Mogador, and his account revived interest in West African exploration. Attempts were made to penetrate the secret of the Niger, both from Senegambia and from the Congo, but both were failures, and a fresh method was adopted, possibly owing to Adams’ experience in the attempt to reach the Niger by the caravan routes across the Sahara. In 1822 Major Denham and Lieutenant Clapperton left Murzouk, the capital of Fezzan, and made their way to Lake Chad and thence to Bornu. Clapperton,
