=Small Export of Oil compared with Kernels.=—The proportionately larger weight of kernel than of palm oil capable of extraction, accounts for the large quantities of kernels exported compared with palm oil. As an example of this, it may be mentioned that in the year 1906 Sierra Leone exported only 12½ gallons of palm oil to each ton of kernels, whereas Southern Nigeria figures for the same year showed 142 gallons of oil per ton of kernels. Since this date, up to the beginning of the war, a comparison of the annual exports of oil and kernels shows a fluctuation between about 12 and 19 gallons of pericarp oil for every ton of kernels; the latter still remaining disproportionately high. =Proposal to introduce New Varieties.=—Since it has begun to be realised that the local variety of palm is probably constantly inferior as an oil producer to some of the varieties found farther to the south, it has been suggested that some of the forms, with a thicker fibrous pericarp and a thin-shelled kernel, should be introduced and planted upon an extensive scale. It is assumed that by doing so, a better type would become established. Experiments made in the Kamerun show, however, that the progeny of palms having a thin-shelled fruit (Lisombe) do not necessarily retain their important characters. Dr. Strunk has suggested that, in the variety mentioned, the characters are not fixed or susceptible of transmission, but the experiments are not considered as yielding conclusive evidence, and it is advisable that experimental plots should be planted with the more useful forms in Sierra Leone and elsewhere, the seed being obtained from artificially fertilised sources. =Improvements in the Local Manufacture.=—During recent years great efforts have been made by the Administration to increase the exports of both palm oil and kernels by opening up the previously rather inaccessible areas in which palm trees were found growing almost untouched. The first step in this direction was the extension of the Sierra Leone Railway line from Boia, a small village just beyond the Headquarters District boundary, to Mafokoyia, lying a short distance to the north. From here a road was made eastwards towards Yonnibannah, passing through country fairly well studded with oil palms. Later from Yonnibannah the objective of the railway became Baga, a town on the Maybole river, again to the north. At the present time this line has reached Kamabai, at the foot of the Koinadugu mountains and to the west of Bumban, passing the town of Makump on its way there. The whole of this route has been chosen in order to make the oil palm regions more accessible, and the increase in exports of both oil and kernels between 1907 and 1913 is almost entirely attributable to this development.
