The Agricultural and Forest Products of British West Africa. By
Gerald C. Dudgeon. (Murray. Is. 6d. net.)—Mr. Dudgeon's admirable handbook was first published in 1911. Much has happened since then, and the changes and developments in West Africa are well summarized in this new edition. Dr. Wyndham Dunstan remarks in his preface that the cultivation both of cotton and of plantation rubber has now been shown to be profitable in Nigeria. He warns us, however, that the Gold Coast cocoa industry, which has developed with surprising speed, will need careful attention if it is to maintain its supremacy. Moreover, the Dutch East Indies and the Malay States are beginning to compete with West Africa in its oldest trade— the supply of palm oil and palm kernels ; the cultivated palms in the Far East, it is-said, yield more oil than the wild palm in its original home.
