Item Derris Agronomy an Annotated Bibliography and a Critical Review Part I(October, 1944) Moreau, R. E.; East African Agricultural Research Institute, AmaniWith the increasing appreciation of the rotenone-containing plants as insecticides, derris is a minor crop that was annually gaining importance up till the end of 1941. Then within the space of a few months, almost the whole of the world sources fell to the Japanese, The American (United States) market, which was the largest consumer, had been mainly supplied from Malaya, the United Kingdom from the same source, Holland and the other continental users from Java and Sumatra. Practically the only other exporting country, on an altogether smaller scale, was the Philippines. Japan had developed an industry, for her own requirements in Formosa.Item On Writing for this Journal(1947) Moreau, R. E.It is perhaps appropriate that after nearly ten years' close association with the editorship of this Journal I should, on my departure, record some of the ideas that have guided me and some of the things that it has taught me. I do not write from an altogether one sided point of view, because I have had a good deal of my own writing published in scientific journals. There is nothing new in any of my cautions or recommendations, but it is certain that they need repeating. On some points I am pernickety: you are at liberty to ascribe the strength of my prejudices to senile obstinacy that seems like mellow wisdom to its possessor.Item The Utilization of Grassland in East Africa(1938) Moreau, R. E.; Gould, J. B.; East African Agricultural Research Station, AmaniIn the article on fodder conservation attention is rightly directed to the wastage involved in the prevalent practice of leaving portions of the rainy season growth to mature in situ. Analyses are quoted showing the detrioration in composition which sets in towards maturity,and reference is made to the losses from fire, dessication and seed production which occur in 'practice. These statements may be read in conjunction with "A Note on Butter Production and Prices" published in this Journal, March 1938 (page 381) in which attention is called to the strongly marked seasonal variation in production of butter in Kenya. "The seasonal range of production is very considerable. exports in the lowest month falling to one-third of the level in the highest month. A large amount of potential production must be lost in the dry seasons." As the author points out, management practices are determined largely by the value of land, by which is meant the real value rather than the commercial value put upon it by speculative activity. This value tends to increase with increase of population and rising standards of living. It is in any case often underestimated and a useful purpose is served by studies which show the way along which live stock husbandry must travel if solid progress is to be achieved
