ami many other useful species. The Aberdare forests (about 750 square miles) contain abundance of similar trees. The Mau forest (about 1,200 square miles) is incompletely surveyed, but is known to contain many ex- cellent timber trees. The forest on Mount Elgon (about 50 square miles) is little known.
The mineral resources are not yet fully explored, but do not appear to be very extensive. There are large deposits of natrou in the Rift Valley, particu- larly at Lake Magadi. Diatomite also occurs in large quant. ties in the same region. Gold has been discovered in S. Kavirondo, but not in sufficient quantities to warrant mining. Graphite and marble are found in the metamorphic rocks in various localities, and limestone is worke<l at various places for building purposes. Manganese is found in the sandstones near the coa*t ; opals have been found in some of the streams on the west side of the Rift Valley, but up to now have not been considered of commerr ial importance.
