Belgian Congo 79 PRODUCTS (OIL-PALM, ETC. ) Beans of many species are to be found in almost every native garden , and their cultivation could be extensively developed.

Bees -wax . — In the Kasai and other districts bees are kept for the sake of the honey. If the value of the wax and the best methods of its collection were ex plained to the natives, as was systematically done in the German African colonies before the war, a very profitable industry might be started .

Benniseed (Sesame, Simsim).—This is grown exten sively in the Welle basin , and yields an oil which is used chiefly for cooking, but also occasionally for light ing purposes . Mixed with kerosene it will burn in an ordinary European lamp.

Camwood .-- The red heartwood of at least two species of forest trees ( Pterocarpus and Baphia ) growing between Stanley Pool and the Western Rift. It pro duces a crimson dye used as a cosmetic by the natives.

The leaves and tubers contain prussic acid , which is got rid of by a process of washing and desiccation in the sun. The leaves are used as a spinach. Tapioca is made from the tubers, which could also be utilized for the produc tion of commercial starch, since they are almost pure starch .

Castor- seed . -A hardy perennial, seen in most dis tricts. The oil is not used by the natives as a purgative, but only as a lubricant for the skin.

Cocoa.—In the Mayumbe district there are several fairly successful cocoa plantations. The Equator dis trict is also suitable for cocoa, and successful experi ments have been carried out in the upper Congo (Aruwimi district) . The plant was introduced from San Thomé. There is no reason why its cultivation
