The great point of interest in this movement consists in the fact, that in promoting the production of cotton in Africa, Englishmen are giving direct encouragement to the employment of slave labor. It is an undeniable fact, that from eight-tenths to nine-tenths of the population of Africa are held as slaves by the petty kings and chiefs; and that, more especially, the women, under the prevailing system of polygamy, are doomed to out-doors' labor for the support of their indolent and sensual husbands. Hitherto the labor of the women has, in general, been comparatively light, as the preparation of food and clothing limited the extent of effort required of them; but now, the cotton mills of England must be supplied by them, and the hum of the spindles will sound the knell of their days of ease. That we are not alone in this view of the question, will appear from the opinions expressed by the _American Missionary_, when referring to this subject. It says: "An encouraging feature in this movement is, that the men engaged in it all feel that the suppression of the slave trade is absolutely essential to its success. The necessity of this is the great burden of all their arguments in its behalf. It thus acts with a double force. There can be no question that the development of the resources of Africa will be an effectual means, in itself, of discouraging the exportation of slaves, while at the same time those who would encourage this development are seeking the overthrow of that infamous traffic as the necessary removal of an obstacle to their success. "There is, however, one danger connected with all this that can not be obviated by any effort likely to be put forth under the stimulus of commerce, or the spirit of trade. This danger can be averted only by sending the missionaries of a pure gospel, a gospel of equal and impartial love, into Africa, in numbers commensurate with the increase of its agricultural resources and its spirit of general enterprise. "The danger to which we allude is not merely that of worldliness, such as in a community always accompanies an increase of wealth, but that the slavery now existing there may be strengthened and increased by the rapid rise in the value of labor, and thus become so firmly rooted that the toil of ages may be necessary for it removal. All this might have been prevented if the spirit of Christian enterprise had gone ahead of that of commerce, and thus prepared the way for putting commerce, under the influence of Christianity. For years Africa has been open to the missionary of the cross, to go everywhere preaching love to God and man, with nothing to hinder except the sickliness of the climate. This evil, and the dangers arising from it, business men are willing to risk, and within the next ten years there will be thousands, and tens of thousands, looking to Africa for the means of increasing their riches."
