MR. A. D. HALL in his opening address to the Agricultural Sub-section of the British Association at Sheffield mentioned “a process of heating the soil before sowing” and “a process of firing the soil preparatory to sowing the crop”, both of which seem very similar to “burning bush” as practised in the West Indies. On reading Russel and Hutchinson's paper on “Partial Sterilisation of Soil” in Journ. Agric. Sci. for October, 1909, it struck me that their work afforded a probable explanation of “burning bush”, and I now make the suggestion in the hopes of obtaining some evidence. The process seems to be similar to that known as chena in Ceylon, ladang in Malaya, and jhuming in India (see J. C. Willis, “Agriculture in the Tropics”, pp. 1 and 2), and perhaps someone with experience of the East could throw further light on the question.
