The “Green seed,” “Volta,” and “Kidney” cottons, which are grown in the Gold Coast, are different in habit from the American and Indian plants, although in form they are similar to Sea Island and Egyptian, having, perhaps, arisen from the same original stock. The forms mentioned as cultivated locally attain the height of from seven to ten feet in nine months from the time of planting, and the stem near the base is often thicker than a man’s wrist. The cotton bolls continue to open for three months or more, and often as many as two hundred bolls are produced on a single plant in one season. If left for a second year the bolls are generally diminished in size. The soil which appears most favourable for growth is a sandy loam containing much humus. From January to April the bolls ripen continuously, and the cotton is placed in the sun as soon as it is picked, in order that the “Seed bugs” may be driven out. In native markets small quantities are usually exposed for sale in an unginned form throughout the harvesting season. No gin seems to be in use in the Gold Coast for native work, and the lint is pulled off the seeds by hand when a supply is required for spinning. The greatest damage is done by “Seed bugs” of three species—_Oxycarenus hyalinipennis_, _O. Dudgeoni_, and _O. gossipinus_—that infest the lint as soon as the bolls open, and undergo their complete and rapid metamorphoses during the period between the opening and the throwing out of the cotton, feeding meanwhile upon the juices which they suck from the seeds. The injury caused by the puncturing of the seed often renders it unfertile. A “cotton stainer” is also common on the plants, and damages the unopened bolls by puncturing, and the lint by a yellowish stain which it makes. This insect is known as _Dysdercus nigrofasciatus_, and it is at least four times as large as any of the species of _Oxycarenus_, on which it may possibly feed to some extent. An attempt was evidently made, in the middle of the last century, to establish the cultivation of cotton for export, and Cruickshank mentions that an association had taken the matter up, and that several of the native chiefs were beginning to give it their attention about that time. Very little success seems to have attended these efforts.
