Abstract
TO students of African rubber, the volume (i) by Dr. Cuthbert Christy, will prove of considerable value. Dr. Christy was for a considerable time connected with the Mabira Forest Rubber Company, Uganda, and had many opportunities of obtaining first-hand information regarding the environment most suitable for Funtumia, the yields of rubber obtainable, and the chemical and physical problems associated with the coagulation of the latex. The author first gives a general account of the African rubber industry, and shows the fluctuation in exports of raw rubber from the Gold Coast, Sierra Leone, Southern Nigeria, Liberia, the French Ivory Coast, Togoland, the Kameruns, the Belgian Congo, and East Africa. There is, however, nothing which would lead one to expect that Africa will henceforth increase its crop of raw rubber, despite the large number of vines and trees which have seen planted during the last few years.
