=RUBBER.=—Recently some species of _Landolphia_ were found growing in the district of Wa and elsewhere, and, upon examination, one of these proved to be _L. owariensis_, P. Beauv. This was at first thought to occur plentifully, and to assume the underground habits of _L. Thollonii_, one of the most important sources of root or rhizome rubber in the Congo. Specimens, which were found growing near the south bank of the Black Volta river, in grass land, exhibited a trailing form of growth owing to the absence of supporting trees, but, although the plants were probably dwarfed by the annual grass fires, no development of root growth was observed in excess of that ordinarily produced within the forests. The plant is now reported to occur rather rarely in the Northern Territories; another nearly allied, though useless, species having been mistaken for it. =DYES.=—For dyeing the yarn made from the native cotton, indigo is made from a species of _Indigofera_, or from the young leaves of _Lonchocarpus cyanescens_, but the process of preparation employed in this country has not been carefully observed. It is, however, probably similar to that in common use in Sierra Leone, Northern Nigeria, and the Gambia. =BEESWAX.=—Bees are attracted to hive in calabashes placed in trees, the honey and wax being taken from them and sold in the markets. The bee belongs to a small variety of _Apis mellifera_, known as var. _Adansonii_. A sample of beeswax obtained at Tamale was examined at the Imperial Institute, and proved to be of excellent quality and worth £6 15_s_. per cwt. (Dec. 1908). =LEATHER.=—Tanning of sheep and goats’ skins is done to a small extent, the same process as that described for the preparation of Kano leather in Northern Nigeria being followed. The _Acacia_ pods used for the purpose are obtained from trees often found planted in the middle of towns. =CATTLE AND POULTRY.=—A large breed of cattle with a dorsal hump exists in the Salaga district, and a straight-backed smaller kind throughout the country to the north. Although “tsetse” flies of three species are common on the stream banks, the cattle seem to be healthy for the most part, and often form part of a caravan travelling to the forest belt, where a good price is said to be obtained for them from the Ashantis. They are usually killed for food very soon after entering the forest, where they can no longer be kept free from the attacks of the three species of “tsetse” (_Glossina morsitans_, _G. palpalis_, and _G. pallidipes_), all of which seem to attack them. Horses are bred in some parts, but not to a large extent. Wire-haired sheep and goats are seen everywhere, and can be obtained in many places at a low price.
