=Importance of Correct Climatic Conditions.=—Cocoa plantations, in order to be successful, require atmospheric moisture fairly constantly throughout the year, and will not thrive if exposed to excessive and prolonged drought, or too much rain. Meteorological records taken at Bo, a place not far distant from that where cocoa experiments were made, show that the conditions in respect to distribution of rainfall, humidity and temperature are unfavourable there. Many attempts have been made in other localities, but only in Northern Sherbro has there been any appreciable success. The soil in this locality is deep and is kept in good tilth by the Gallinas. The price obtained locally for their cocoa beans was, in 1913, from 3_d_. to 4_d_. per lb.; in 1914 there was an increase in the number of plants put out, as the price rose in that year to 6_d_. per lb. A sample of native cocoa was submitted to the Imperial Institute for examination and report in 1916, and was found to be incompletely fermented with a rather harsh flavour. The trade valuation, however, was equal to the standard price ruling for Accra beans at the same time (cf. _Bull. Imp. Inst._, 1916, p. 589). Although the outlook for Northern Sherbro is promising, cocoa cannot attain much success in the country generally, on account of unsuitable climatic conditions and general ineptitude of most of the native tribes. =COFFEE.=—A few years ago coffee was grown in the Colony for export, the indigenous variety, _Coffea stenophylla_ as well as _C. Liberica_ being planted. The former bears a very small berry and yields an excellent, strong-flavoured beverage. The latter is better known and has a large berry. Throughout the hill villages of the Colony a great number of trees are seen, but, owing to a fall in the price of the product, most of the crop remains unpicked, although it should not prove unremunerative even at the present prices to continue the export. =INDIGO.=—Species of Indigofera and a scandent shrub, _Lonchocarpus cyanescens_, or “Gara” (Mendi), are used for the extraction of the blue dyes commonly employed in the country. The leaves of the latter plant are said to be in such demand that a quantity is annually imported from Southern Nigeria. A description of the method of dyeing with “Gara,” and an explanation of the process, are given in the _Bulletin of the Imperial Institute_, vol. v. (1907), p. 129. =FRUIT.=—Some parts of the Colony seem favourable for the cultivation of various tropical fruits, such as bananas, oranges, mangoes, and pineapples, and it is possible that the proximity of Sierra Leone to European ports might enable some of these to be grown for export.
