32 HISTORY [10.99 900,000 square miles of territory, prepared to define the limits of his African kingdom . On the north the Convention of 1885, supplemented by that of 1891 with Portugal , determined the boundary of the Cabinda enclave, and, on the south, settled the frontier on the Lower Congo from its mouth to Noki, and from that point to the Kwango ; thence the line follows the course of that river as far as the 8th parallel, and, dividing the Lunda country ( otherwise known as the territory of Muato Yanvo) , ascends the Kasai to the watershed of the Congo and the Zambezi, which it follows to the 24th meridian east .

(7 ) FRONTIER CONVENTIONS WITH FRANCE The frontier with the French Congo was the subject of lengthy negotiations. It was finally laid down by the Convention of 1885, under which France acknow ledged the right of the Association - now the Congo Free State—to the course of the Lower Congo below Manyanga as the boundary between her possessions and those of the Congo Free State. A further con vention, signed in 1887, defined the frontier from Manyanga to the confluence of the Ubanghi with the Congo, and thence to the intersection of the Ubanghi, with the 4th parallel, which was declared the northern limit of the Congo Free State. The Free State was . thus excluded from the Niadi valley, and, within certain limits, from the right bank of the Ubanghi. In return , King Leopold obtained from France a statement that the French right of pre -emption to the territories of the Congo Free State was not intended to prejudice that of Belgium , should the King declare that country his successor ; he was further allowed to have quoted on the French Bourse 80,000,000 francs of the loạn ( 150,000,000 francs) which , in 1888, he decided to float.
