68 WEST AFRICAN FORESTS AND FORESTRY 
13. Brachystegia spiceformis, which yields a light-brown hardish 
timber with very pretty grain. (See illustration No. 104, which shows 
a very large specimen of this tree in Nigeria.) It is very prevalent, 
in fact one of the commonest trees in the Gola Forest, so that large 
quantities of timber could be obtained. 
14. Wismah (Sierra Leone name) is also found, and apparently 
grows up very quickly in old farms. : 
15. The Red Oak (Berlinia auriculata) is quite prevalent, especially 
near the banks of streams. It attains a large size, and the timber 
has been sold as oak in the European market. Here it has not yet 
been cut. 
In addition to the trees which can be felled for conversion into 
export timbers, there are others which may be cut for sale locally, 
such as: 
16. The Brimstone (Morinda citrifolia?), one of the most suitable 
trees for the purpose. One of the largest trees was 5 feet in diameter, 
and had also a clear bole of 50 feet. On the whole it grows to a 
larger size in the Gola Forest than in Sierra Leone. I[llustration 
No. 10 shows one of these trees from which a timber specimen had 
been cut. 
17. The Hamon, which is apparently a species of Sterculiacee, 
although not of enormous size, has a straight bole, which divides up 
into four or five very large and thin root flanges. It is one of the 
most prevalent trees in the forest. Illustration No. 14 shows the 
peculiar formation of the roots of this tree. 
18. Piptadenia africana, a very large tree with small and fine 
pinnate leaves. It is frequently met with, in fact one of the commonest 
of the trees in the forest. It yields a hard brown wood which is 
durable. 
19. The so-called Mountain Mahogany, probably a species of 
Leguminoseez. It attains a large size, and yields a timber not unlike 
that of Red Pine. 
Up to the present no local or other sawyers have worked in this 
forest. Although only a few trees have been mentioned which could 
be cut for use locally, there are many others out of approximately 
a hundred different kinds which are found in the forest. 
There are other products, such as oil beans, obtained from Penta- 
clethra macrophylla, a large forest tree; gum copal, obtained from 
Daniellia Ogea, one of the largest forest trees; palm oil and kernels 
from the Oil Palm (Hlesis guineensis), which is found in all the 
clearings. Piassava, obtained from Raphia vinifera, is found on the 
banks of the two rivers, Morro and Mano. Rubber could be obtained 
from the African Rubber Tree (Funtumia elastica) and various rubber 
vines, such as Landolphia Owariensis, and others. Dika nuts could 
be procured, as the tree which bears them, Irvingia Barteri, is com-
