=TOBACCO.=—Tobacco is produced near Ibadan, and large quantities are sold in the King’s market of that town. It is probable that the curing of the leaf is done completely in the sun, as the prepared material is of a rather light colour and has a mild flavour. The leaves are apparently rather mixed, and old or immature examples are frequently included in the same grade. Experiments will be taken in hand with a view to the improvement of the quality, but at present the local demand is so great that there is little prospect of an export trade becoming established. Recent work in Nyasa-land has shown that good pipe smoking tobacco, suitable for consumption in England, can be produced in Africa. =SILK.=—The preparation of a silk yarn, carded and spun from the boiled cocoons of wild silkworms, is a common occupation of some of the women of Ibadan. The identity of the insects producing the silk has been determined to be _Anaphe infracta_ and _A. venata_, both of which form congregated masses of cocoons. The yarn is of a brown colour, and is woven with cotton into a cloth which is called locally “Saṉyaṉ.” It is much valued by the natives on account of its durability. The silkworms show some sign of becoming scarce owing to the utilisation of the pupæ as food. (See _Bulletin of the Imperial Institute_, 1910, p. 150; 1916, p. 168; and 1920, p. 319.) =COCONUTS.=—The preparation of copra is carried on at Badagri, where a large coconut plantation exists. Great alarm was recently caused to the proprietors through the attack of a scale insect (_Aspidiotus destructor_), which destroyed the leaves of a very large number of trees. The advent of this pest was, however, quickly followed by the vast multiplication of the numbers of a species of large ladybird beetle, which soon checked the spread of the scale. The directions issued by the Forestry Department with regard to the means of destroying the infected leaves also assisted in the extermination of the blight. =MAHOGANY AND EBONY.=—Among the valuable exported products from the country, mahogany and ebony must be regarded as occupying an important place. The largest proportion of the timbers exported to Europe and sold under the name of mahogany are obtained in the Central Province, and are cut from trees belonging to the genera _Khaya_, _Pseudocedrela_, and _Entandrophragma_, of the Natural Order _MELIACEÆ_. Mr. Thompson, Conservator of Forests, remarks that a fair number of logs cut from a species of _Guarea_, of the same Natural Order, have been shipped, and have obtained good prices in Europe. A red wood, called locally “Iroko” (_Chlorophora excelsa_), which is in good demand in the country for making furniture, etc., has been shipped to Europe, but at present there is little demand for it. A photograph of another timber tree (_Terminalia superba_) is given (Fig. 24).
