CONCLUSION. Here we must close our inquiries, sum up the results, see what experience teaches, draw the contrasts between these several classes of Missions, and determine the best mode of employing human instrumentalities for the extension of the Gospel in Africa. These Missions, as we have shown, had to be planted upon a broad field of barbarism; where the civil condition, the objects of worship, the social customs, the intellectual state of the people, were the antagonists of what prevail under a Christian civilization. The missionary’s task embraced much of toil, privation, danger, patience, perseverance. Wars were to be turned into peace, superstitions overthrown, polygamy abolished, ignorance dispelled, before civilization and Christianity could be established. This was the work to be accomplished. The results have been given in detail, and now they must only be recapitulated and contrasted. The Missions to the natives, beyond the protection of the colonies, have made the least progress. They are established upon the proper basis, but have fewer agencies employed than the other missions, and a corresponding inefficiency is the result. Common schools, Sabbath schools, and preaching, are means used for promoting the Gospel in all the African missions. Those to the natives, are limited chiefly to these three plans of operation, while the other missions possess many subordinate means that greatly facilitate their progress. Preaching to adults, though not altogether unsuccessful, has won but few converts, and done but little for the overthrow of superstition. Education lays the axe at the root of ignorance, but from the fewness of the teachers and schools, the small attendance of pupils, and the reaction of heathenism upon them, it has made very little impression on the surrounding barbarism. Less, still, has been done by these missions, in preventing native wars; while polygamy remains almost wholly unaffected by them. The greatest difficulty, however, is, that the missionaries, with very few exceptions, are white men, whose constitutions, generally, yield to the effects of the climate, and the missions are constantly liable to be weakened and broken up. This is true of the Gaboon and Mendi Missions, particularly, and can be remedied, only, by substituting colored missionaries, since they, alone, have constitutions adapted to the climate. The mission to the Zulus differs from these two, in having a climate better adapted to the Anglo-Saxon; but it has to contend with the additional obstacle of a hostile white immigration, which threatens its existence. As the customs and morals of Christianity become better understood, at these missions, the enmity of the natives continues to increase; and the missionary, after years of toil, feels, more and more, the indispensable necessity of multiplying the agencies for removing the barriers to the Gospel by which he is surrounded.
