The bulk of the oil is exported to England (£1,191,000 value in 1909), but nearly the entire kernel crop goes to Germany, where it is treated by the big crushing mills. It is possible that this state of affairs may undergo considerable change within the next decade, and the reason for it is, incidentally, of considerable economic interest, as it is of moment to Nigeria. Up to within three or four years ago palm kernels were crushed and the oil almost entirely used by the soap trade, but chemistry has now found a process of refining and making palm-kernel oil edible, as it may, perhaps, do some day for palm oil itself, as a base for margarine, for which coprah and ground-nut oil were formerly employed. This has had as a consequence an enormous widening of the home market, and the soap trade has now to contend with keen competition for the supply of one of its staples. The resultant effect is the initiative of Lever Brothers (Limited), who, finding the need of enlarging and giving increased security to their supplies of the raw material, are, with commendable enterprise, erecting three large crushing mills in Southern Nigeria, the one at Lagos being already in a fair way to completion. If the numerous difficulties they will have to face are successfully negotiated, the ultimate result can hardly fail to be that of transferring the considerable palm kernel crushing industry from the banks of the Rhine to those of the Niger, besides creating a new export trade in oil cake from the Niger to England and the Continent.

CHAPTER III
THE FOREST BELT
Beyond the deltaic region proper lies the vast belt of primeval and secondary forest of luxurious growth, giant trees, tangled vines and creepers, glorious flowering bushes, gaudy butterflies, moist atmosphere, and suffocating heat. Beyond the forest belt again lies, with recurrent stretches of forest, the more open hilly country, the beginning of the uplands of the North. When an authority on forestry recently wrote that “British Columbia is the last great forest reserve left,” he forgot West Africa. That is what West Africa has continually suffered from—forgetfulness. The resources of the Nigerian forest belt are as yet far from being fully determined, but sufficient is now known of them to show that they are enormously rich. Besides the oil palm and the wine palm (which produces the piassava of commerce) the forest belt contains large quantities of valuable mahoganies, together with ebony, walnut, satin, rose, and pear woods, barwood, and other dye-woods, several species of rubber, African oak, gums (copal), kola, and numerous trees suitable to the manufacture of wood-pulp. Oil-bearing plants abound in great quantities, as do also fibres, several of which have been favourably reported upon by the Imperial Institute. The shea-butter tree, to which I shall have occasion again to refer, is an inhabitant of the dry zone.
