No less difficult were the natives themselves. Before the advent of the American engineers, industry was unknown in the Upper Kasai. The only organized activity was the harvesting of rubber and that was rather a haphazard performance. With the opening of the mines thousands of untrained blacks had to be drawn into organized service. They had never even seen the implements of labour employed by the whites. When they were given wheel-barrows and told to fill and transport the earth, they placed the barrows on their heads and carried them to the designated place. They repeated the same act with shovels.
The Yankees have thoroughly impressed the value and the nobility of labour. I asked one of the employes at a diamond mine what he thought of the Americans. His reply was, "Americans and work were born on the same day."
The labour of opening up the virgin land was only one phase. Every piece of machinery and every tin of food had to be transported thousands of miles and this condition still obtains. The motor road from Djoko Punda to Kabambaie was hacked by American engineers through the jungle. It is comparatively easy to get supplies to Djoko Punda although everything must be shifted from railway to boat several times. Between Djoko Punda and Tshikapa the material is hauled in motor trucks and ox-drawn wagons or conveyed on the heads of porters to Kabambaie. Some of it is transshipped to whale-boats and paddled up to Tshikapa, and the remainder continues in the wagons overland. During 1920 seven hundred and fifty tons of freight were hauled from Djoko Punda in this laborious way.
At the time of my visit there were twelve going mines in the Congo field, and three new ones were in various stages of advancement. The Forminiere engineers also operate the diamond concessions of the Kasai Company and the Bas Congo Katanga Railway which will run from the Katanga to Kinshassa.
More than twelve thousand natives are employed throughout the Congo area alone and nowhere have I seen a more contented lot of blacks. The Forminiere obtains this good-will by wisely keeping the price of trade goods such as salt and calico at the pre-war rate. It is an admirable investment. This merchandise is practically the legal tender of the jungle. With a cup of salt a black man can start an endless chain of trading that will net him a considerable assortment of articles in time.
The principal natives in the Upper Kasai are the Balubas, who bear the same relation to this area as the Bangalas do to the Upper Congo. The men are big, strong, and fairly intelligent. The principal tribal mark is the absence of the two upper central incisor teeth. These are usually knocked out in early boyhood. No Baluba can marry until he can show this gaping space in his mouth. Although the natives abuse their teeth by removing them or filing them down to points, they take excellent care of the remaining ivories. Many polish the teeth with a stick and wash their mouths several times a day. The same cannot be said of many civilized persons.
I observed that the families in the Upper Kasai were much more numerous than elsewhere in the Congo. A Bangala or Batetela woman usually has one child and then goes out of the baby business. In the region dominated by the Forminiere it is no infrequent thing to see three or four children in a household. A woman who bears twins is not only hailed as a real benefactress but the village looks upon the occasion as a good omen. This is in direct contrast with the state of mind in East Africa, for example, where one twin is invariably killed.
I encountered an interesting situation concerning twins when I visited the Mabonda Mine. This is one of the largest in the Congo field. Barclay, the big-boned American manager, formerly conducted engineering operations in the southern part of America. He therefore knows the Negro psychology and the result is that he conducts a sort of amiable and paternalistic little kingdom all his own. The natives all come to him with their troubles, and he is their friend, philosopher and guide.
After lunch one day he asked me if I would like to talk to a native who had a story. When I expressed assent he took me out to a shed nearby and there I saw a husky Baluba who was labouring under some excitement. The reason was droll. Four days before, his wife had given birth to twins and there was great excitement in the village. The natives, however, refused to have anything to do with him because, to use their phrase, "he was too strong." His wife did not come under this ban and was the center of jubilation and gesticulation. The poor husband was a sort of heroic outcast and had to come to Barclay to get some food and a drink of palm wine to revive his drooping spirits.
The output in the Congo diamond area has grown from a few thousand karats to hundreds of thousands of karats a year. The stones are small but clear and brilliant. This yield is an unsatisfactory evidence of the richness of the domain. The ore reserves are more than ten per cent of the yearly output and the surface of the concession has scarcely been scratched. Experienced diamond men say that a diamond in the ground is worth two in the market. It is this element of the unknown that gives the Congo field one of its principal potentialities.
