The Wesleyan Methodist Missionary Society was founded in 1813, and devoted its first efforts to South Africa, Namakwaland, and Kaffraria. The Primitive Methodist Society was started in 1843, and continued the evangelization of Fernando Pô, which had been carried on by the (British) Baptist mission from 1844 to 1859. They also went at the same time to South Africa. The prospects of this mission in Fernando Pô were affected by the resumption of the administration of that island by the Spanish Government, which at that time discountenanced Protestant missions in its territory. Some arrangement was come to, however, and the mission still continues to work there, and to work at the present time without any very marked restriction. The Society for the Propagation of the Gospel became a distinctly missionary body in 1821, and worked chiefly in South Africa. The British Baptists organized a missionary society early in the 19th century, and sent out missionaries as far back as 1840 to Fernando Pô. Owing to their expulsion from the island by the Spanish Government, they moved across to the Cameroons, where they established the flourishing settlement of Ambas Bay, and made English almost the second language of the Cameroons people. The splendid work of this mission in the Cameroons was chiefly done under the late Edward Saker, whose name is still venerated on the Cameroons river for the great good that he did to the country by spreading the knowledge of many useful arts and industries and educating the Duala people to a remarkable degree. From the Cameroons the mission, under the guidance of the Rev. Thomas Comber and the Rev. Holman Bentley, moved on to the Congo[138], where this Baptist mission now has numerous stations. One of its missionaries, the Rev. George Grenfell, made himself famous by discovering the great Mubangi river, the most important of the Congo tributaries, and known in its upper waters as the Wele, besides making a remarkable survey of the main Congo and several of its leading tributaries, thus earning the Gold Medal of the Royal Geographical Society and a number of other distinctions. Though several times offered posts of responsibility under the Congo Government he preferred remaining a missionary till his death in 1906. The linguistic work done by this Baptist mission was important, and included an illustration of the language of Fernando Pô by Mr John Clarke, a like service rendered to the Duala language of the Cameroons by Mr Saker, a valuable Congo dictionary and grammar by the Rev. Dr H. Bentley, and work of far-reaching interest and importance by the Rev. W. H. Stapleton.
