Coco-NUT oil derived from copra is by far the most important ultimate product of the coco-nut palm, and the future prospects of the industry are reviewed in a volume under this title, which appears as the second volume of a “Survey of Oil Seeds and Vegetable Oils” (London: H.M. Stationery Office, 2s. net). Within the last ten years there has been an increase of about thirty per cent in the world acreage under coco-nuts, bringing the total to 7,000,000 acres in 1931. Since 1921 the British Empire has accounted for slightly more than half this amount. The increase in production has been mainly due to the demand from the United States, but the needs of that country can be met by the production from the Philippines. Other producing countries, including those of the British Empire, must be chiefly dependent upon European consumption. Owing to the heavy production of whale oil, however, there is at present no sign of an increased demand in the European market. In this market the demand for coco-nut oil depends upon the expansion of the soap and margarine industries. The survey concludes that the output of copra will be on the increase for several years and that the bulk of this will appear on the world market, although local consumption accounts for a considerable proportion of the output of most producing countries, especially of India, the Dutch East Indies, and the South Sea Islands.
