The whole process is beyond question most wasteful, particularly where the natives not only sever the vine, but dig up the roots, compelling these also to yield up their stores of latex. To-day as the traveller marches through the rubber forests of the Congo basin he meets every few yards little heaps of decaying vine from which the rubber has been taken. Frequently too, one sees overhead a tangled mass of dead vine which has withered away through the main stem having been severed. The natives were either in too great a hurry, or else unable to climb for those spreading vines which would often measure some hundreds of yards.
Another method is that adopted by the native tribes in the Kasai River of the Congo, and the Lunda province of Portuguese Angola. Whole families or tribes will make a temporary home in the forest, pitching their little huts on a piece of high ground near a stream. Every day the men will scatter in all directions cutting down and gathering the vines into bundles which they will convey to these little encampments.
The bark of the vines is then stripped off and laid out on blocks of wood, old canoes, boards, or trunks of trees, preparatory to beating it with heavy wooden mallets, which process gradually reduces the bark to a stringy mass not unlike shredded tobacco. It is then threshed with smaller mallets which in time gradually pulverize the wood element into fine powder, leaving “pancakes” of red rubber, about the size of a breakfast plate. These are then cut into thin strips, starting from the outer edge, and wound into balls, just as the manufacturers wind balls of knitting wool. This method though equally wasteful in collection, conserves the whole of the rubber latex.
Travellers in the Kasai territories of the Congo are generally first aware of their approach to human habitation by hearing the distant thud, thud, of the rubber mallets which is a feature of almost every village of that region.

Hand in hand with the rubber work of the Congo is that of cane basket making, which the busy women weave in all sizes for packing the rubber, thus avoiding the heavy cost of importing “shooks” or barrels from Europe. Every year some hundreds of thousands of these light but very strong hampers are made for conveying the rubber to the buying stations and thence to the European markets.
