(ii) The institution of a proper rotation of crops suitable for each district or locality. (iii) The demonstration to natives of the fact, that, by the proper employment of manuring and crop rotation, they would be able to farm the same piece of land for an indefinite number of years, during which time it should increase rather than diminish in fertility. By such demonstration it should be possible to put an end to the wasteful and permanently destructive methods at present employed of shifting cultivation. The Agricultural Department has a piece of land on the Experiment Farm at Njala, which has been under crops annually for the past eight years, and the condition of it at present is said to be a more fertile one, owing to the system of manuring and rotation employed, than it was at the commencement of work. This is mentioned here, as it is in contradiction to the well-worn native excuse for changing the site of farms annually, _i.e._, that it is essential for the maintenance of the fertility of land that after a few years’ cultivation the “bush” be allowed to become re-established so that, on burning, a sufficient amount of wood ash may be obtained to renovate it. (iv) To encourage the natives in the formation of permanent plantations of fruit and other economic trees. To these ends, in the first place, analyses of soils from various parts of the country have been made by the Imperial Institute. At the same time samples of the soil taken from localities where kola, cocoa, rice and groundnuts were grown, have been compared with that from uncleared “bush.” The result of the examination, in the latter case, showed the soil had a deficiency of lime and phosphoric acid. A special analysis was also made of the soil of the Banana Islands, which was found to have an adequate quantity of nitrogen but to be deficient in potash and phosphoric acid. With a view to producing a more satisfactory condition of soil in some parts, different leguminous crops have been cultivated and alternated with Sorghum millet (Guinea corn), maize and rice. Among the species tried by the Agricultural Department are: soya beans (_Glycine soja_), black gram (_Phaseolus mungo_), pigeon peas (_Cajanus indicus_), Java beans (_Phaseolus lunatus_), cowpeas (_Vigna catjang_), sword beans (_Canavalia ensiformis_) and horse-beans (_Dolichos lablab_). Yams and groundnuts have also been tried, and a yield of 6 tons 3 cwts. per acre of the former crop was obtained at the experimental farm at Njala in 1914.
