In Kano, cotton is often grown in alternation with cassava, and is a manured crop. Large fields are not seen, as the land is chiefly required for food crops, especially in the vicinity of towns, where the population is dense. General improvements in cultivation, and the introduction of ploughing, would enable a much larger area to be put under cultivation, and would permit of the fertile tracts remote from the towns being employed largely for cotton-growing. The above account indicates the direction in which efforts should be made to ensure the most fertile tract of Northern Nigeria, where the population is also most industrious and dense, becoming an important cotton-growing locality. It may be safely said that the land, climate, and industrious population are existent and suitable, but the population is congested, leaving large fertile areas of land untouched. Transport difficulties have up to the present prevented cultivation of products useful for export, and the non-employment of cattle for ploughing has restricted cultivation to the growth of crops entirely absorbed by local necessity. =Improvement of Plant.=—In addition to these requirements, with regard to cultivation, a rather better class of cotton is necessary in the Northern Provinces. The local variety might perhaps be sufficiently improved under better cultivation and seed selection, but such a process would be gradual and require the undivided attention of an experienced European officer, working in the districts. It has previously been suggested that the introduction of one of the many Upland American kinds might be advantageous; the local variety approaching that class of plant more nearly than do the varieties occurring in the forest regions farther to the south, where the American varieties have been extensively planted with somewhat variable results. One variety only should be introduced, and this should possess cropping and lint records suitable for European requirements. Georgia or Texas quick-maturing kinds are indicated, but not the lowland kinds such as are grown in the Mississippi valley. The foregoing remarks apply to those regions only where it seems possible that the quality of cotton which is in most general demand in Lancashire can be extensively grown, but are not applicable to the Niger Valley. As will be seen by a reference to the table of valuations, a cotton exists in the Bassa and Nassarawa Provinces which is comparable with a higher standard grade than Middling American, the type to be produced in the north. Efforts should be made to keep this latter variety free from the possibility of admixture with exotic kinds, and it is therefore advisable that improvement in this class should be confined to seed selection. American cottons have already been introduced into Bassa, but the value of the lint is lower than that of the indigenous kind.
