Dahome, and Benin, with the tribes who, from a distance of twenty-five days, bring gold to Tinbuktu (the Tungubutu of De Barros, i. 220). Thus the lakes of Wangara would be the lagoons of the Slave-coast, in which the Niger may truly be said to lose itself. At length M. Reichard, of Lobenstein ("Ephémerides Géographiques," Weimar, 1802), theoretically discovered the mouth of the Niger, by throwing it into the Bight of Benin. He was right in essentials and wrong in details; for instance, he supposed the Rio Formoso or Benin River and the Rio del Rey to join in one great stream beyond the flat alluvial delta: whereas the former is indirectly connected through the Wari with the Niger, and the latter has no connection with it at all. The truth was received with scant courtesy, and the hypothesis was pronounced to be "worthy of very little attention." There were, however, honourable exceptions. In 1813, the learned Malte-Brun ("Précis de la Géographie Universelle," vol. iv. 635) sanctioned the theory hinted at by Mungo Park, and in 1828 the well-abused Caillié, a Frenchman who had dared to excel Bruce and Mungo Park, wrote these remarkable words: "If I may be permitted to hazard an opinion as to the course of the River Dhioliba, I should say that it empties itself by several mouths into the Bight of Benin." In 1829, fortified by Clapperton's opinion, my late friend, James Macqueen, who to immense industry added many qualifications of a comparative geographer, recommended a careful examination of the estuaries between the Rio Formoso and Old Calabar. The question was not finally set at rest till 1830 (November 15th), when Richard and John Lander entered Yoruba viâ Badagry and, triumphantly descending the lower Niger, made the sea by the "Nun" and Brass embouchures. Meanwhile, Mr. George Maxwell, a Scotchman who had long traded in the Congo, and who subsequently published a chart of the lower river proposed, at the end of the last century, to take from England six supernumerary boats for rowing and sailing, which could be carried by thirty people and portaged round the cataracts. This gave rise to Captain Tuckey's first error, depending upon labour and provisions, which were not to be had "for love or money" anywhere on the Congo above the Yellala. With thirty or forty black rowers, probably Cabinda men, Maxwell advised navigating the river about May, when the Cacimbo or dry season begins; and with arms, provisions, and merchandize he expected to reach the sources in six weeks. The scheme, which was rendered abortive by the continental war of 1793, had two remarkable results. It caused Mungo Park's fatal second journey, and it led to the twin expeditions of Tuckey and Peddie.
