THE first International Congress of Tropical Agriculture was held in Paris in 1905, and was organised by a number of French men of science interested in this subject. At its close the Association Scientifique Internationale d'Agronomie Coloniale et Tropicale was founded, to promote in every possible way scientific work in tropical agriculture. Branches of this association were gradually founded in Belgium, France, Germany, Great Britain, Italy, Portugal, and elsewhere, until at present practically every country interested, either on its own account or through its colonies, in tropical agriculture, is represented on the Central Bureau of the association, which has its headquarters in Paris. In 1910 a very successful second Congress of Tropical Agriculture was held in Brussels. At the close of that congress M. de Lanessan, formerly Governor-General of Indo-China, who had up till that time been president of the association, retired, and was succeeded by Prof. Wyndham Dunstan, C.M.G., F.R.S., director of the Imperial Institute.
