498 WEST AFRICAN FORESTS AND FORESTRY 
The Agricultural and Forest Products of British West Africa, by 
G. C. Dudgeon, Director-General of Agriculture in Egypt, 1911, gives 
a short description of the main forest and agricultural products of 
the country, which is more useful to the trader than the forester or 
timber merchant. The illustrations showing the making of palm 
oil and other country products are very interesting, but Fig. 21, 
p. 112, supposed to be of an Iroko tree, is in reality that of Terminalia 
superba. : 
For reference purposes Dr. Adolf Engler’s Syllabus der Pflanzen- 
familien, 1904, which takes special account of the medicinal and use- 
ful plants, is most valuable. 
For a proper introduction to Botany, Strasburger’s Text Book 
of Botany is hard to beat. 
Kulturgewdchse der Deutschen Kolonien, by R. Sadebeck, 1899, 
gives a very good account of most of the useful West African forest 
products; the very clear illustrations add immensely to its value, 
although the book is now somewhat out of date. 
3. TIMBERS. 
In The Timbers of Commerce and their Identification, by Herbert 
Stone, F.L.S., F.R.C.1., 1904, a few of the West African timber trees 
are mentioned, but only very cursorily, with but few illustrations. 
In Timber, by J. R. Baterden, A.M.I.C., a few of the West African 
timber trees are described, and a few photographs show how the 
timber is worked. Their inclusion amongst the South African timbers 
does not exactly enhance their value or give a true view of their place 
in the economy of the timber trade. 
Wood, by G. S. Boulger, gives an excellent system for classifying 
woods by using al] their various characteristics, such as taste, smell, 
hardness, structure of the timber, and the various pith rays and other 
peculiarities. A very complete list of all the various timbers used 
in commerce is given, together with the various synonyms of each, 
and the botanical names of each so far as they are known. The uses 
of the timber and the supplies of each country are given, and in this 
way it is a most important book of reference for any Forest Officer. 
4, Forestry GENERALLY. 
In Sylviculture in the Tropics, by A. F. Broun, Director of Woods 
and Forests, Soudan, 1912, some references are made to West African 
trees. Some very typical photographs of forest vegetation in various 
parts of the Tropics are very useful, and demonstrate several forest 
theories far better than pages of words. 
A Dictionary of the World’s Commercial Products, by J. A. Slater, 
B.A., LL.B., 1907, is very useful for looking up the lesser known 
forest products. The descriptions have to be used with discrimina-
