A previous series of thirteen years’ exports from the former showed an average of 60·9 gallons of oil to the ton of kernels; while for the latter a twelve-year period at the same time gave 219·6 gallons of oil to the ton of kernels. The mean for the whole was 140·25 gallons at that time, but during the last seven years it has fallen to 125·7 gallons. In 1912 the first shipments of kernel oil and cake were made from factories established under European control at Opobo and Lagos, the amounts exported being 500 tons of oil and 635 tons of cake. In the following year the value of both products turned out by these factories is given as £161,000, and in 1914 as £72,000, when, without any assigned reason, both factories were closed down. Articles on the African palm-oil industry in the Southern Provinces of Nigeria will be found in _Bulletin of the Imperial Institute_, 1909, 1911, 1912, 1913, 1914, 1915, 1919. An interesting article appears in the _Bulletin of the Imperial Institute_, vol. xviii., No. 2 (1920), entitled “The Cultivation of the African Oil Palm, with special reference to the East Indies.” From this it appears that the tree thrives and yields very satisfactorily, especially in Sumatra; the oil content of the fruit and kernels being both high. Attention is drawn in this article to the extension of the use of palm oil in Europe as an edible fat, in addition to its present uses. =Other Oil Seeds.=—Excluding the shea nut tree, which will be referred to later on, three trees have been considered of sufficient importance for their seeds to be shipped to Europe in order that their value may be determined. These are _Pentaclethra macrophylla_ (Cutlass bean), _Irvingia Barteri_ (African mango), and _Lophira alata_. Although the trials proved that the oils of all might be valuable for the manufacture of soap and candles, none of the trees occur in sufficient profusion to permit a large export trade in the seeds being established.
