Everywhere in West Africa the cry goes up, “Give us more labour.” The British, German, Portuguese and French merchants all declare that if only they could get the labour, they might put a different face on the whole of the problems of production in West Africa. The principal reason for this shortage is unquestionably the fact that West Africa is sparsely populated, but this one fact does not, by any means, explain the situation. In Liberia alone does there appear to be any appreciable quantity of surplus labour, and upon its resources considerable demands are made by other colonies. This surplus obviously arises from the fact that Liberia is completely undeveloped, but if in the near future some energetic power should take charge of that territory, a period would certainly be put to indiscriminate recruiting amongst the native tribes. It is true that in some territories in West Africa there is an increase in the population, but taking the whole areas into review, the labour force has seriously decreased within recent years. Statistics, though at present little more than estimates, go to prove that in several colonies this falling off is becoming a grave question. Recently the religious denominations in Lagos have been holding “intercessions” with reference to the high rate of mortality. If this intercession should lead the natives from faith to works, we may still hope to see the abandonment of those European customs which are doing untold harm to the physique of the native women and children. The causes of decrease in the population, generally speaking, are beyond human ken and one can only express opinions which someone else will promptly contradict. For example, almost every traveller wrecks his reputation on that old-time rock of controversy—polygamy. Sir Harry Johnston mentions in one of his books the case of a polygamist with 700 children, but the greatest polygamist I have ever met in Africa possessed 1000 wives, yet he had no children! Argument based upon two such instances, however, is profoundly unsatisfactory, because with so large a company of wives in one case, and children in the other, it is obvious that many other considerations repose beneath the surface. There is one outstanding fact which everyone knows, but few speak about except in whispers; human nature is pretty positive in West Africa, no matter of what hue the skin, and scientists may argue until eternity upon the relative effects of polygamy and monogamy on the birth rate, but all their deductions are wide of the mark whilst they have so little actual monogamy anywhere in West Africa.
