THE first edition of this excellent handbook was reviewed in NATURE for February 25, 1915 (p. 695). In the new edition the subject-matter remains substantially the same, and the revision consists chiefly in recording the results of certain scientific work relating to the coco-nut industry carried out in the Philippines during the last six years. Reference is made to the investigations on copra and coco-nut oil by Messrs. Brill, Parker, and Yates in 1917, which dealt mainly with the conditions governing the production of a fine-quality copra of high oil-content. On the cultural side an account is given of the discovery, by Reinking in 1918, that the primary causative organism of bud-rot of the coco-nut palm in the Philippines is Phytophthora Faberi, Maub. It would have been useful to mention that a serious bud-rot of coco-nut palms in southern India (Malabar) was described by Shaw and Sundara-raman in 1914 as due to Pythium palmivorum, Butl. References are also made to interesting work on the growth and behaviour of young and ripening coco-nuts, and to the use of the nuts of young trees as seed. In the foreword the author refers to the impetus given during the war to the export of coco-nut oil from coco-nut-growing countries in place of copra. In his opinion the remarkable advance in this direction made in the Philippines during recent years would have been impossible but for the scientific and educational work on coco-nut cultivation organised by the Philippine Government.
