African Mahogany includes several species of widely different 

 origin to those already mentioned under Meliaceae. There is 

 little doubt, however, that it was the wood of this species which 

 first found its way into commerce as West African Mahogany. 

 The Liverpool trade in the wood originated on the Gambia, from 

 which colony specimens were first sent to Kew and proved to be 

 Khaya senegalensis. According to Mr. James Irvine the export 

 began in the autumn of 1886 with about 250 tons (Kew Bull. 1894, 

 p. 8) ; by 1895 the trade had increased to such an extent that the 

 important mahogany industries of British Honduras and neigh- 

 bouring countries were seriously affected ; shipments were also 

 then being made to the United States (Kew Ball. 1895, p. 80). In 

 1904 the trade in the West African wood was on such a scale that 

 it could be stated (Timber Trades Journal, 1904, p. 571), " It has 

 made this country largely independent of the production of the 

 West Indies, and it is in this direction that we now and in the 

 future will have to rely for our importations of mahogany." Of 

 a total import (in 1903) from all sources of about 20,000,000 feet, 

 nearly 18,000,0 JO feet was received from West Africa (Chaloner's 

 Report, Liverpool, Jan. 2nd, 1905). The development of the 

 trade with Southern Nigeria and the United Kingdom is shown 

 in the accompanying chart, compiled from Annual Statements of 

 the Trade of the United Kingdom prepared at the Custom House. 

 The figures are given under Lagos and Niger Protectorates 

 throughout for the 14 years represented. 



In 1908 the exports from N. and S. Nigeria amounted to 

 28,750 tons, value £260,994 (Trade of the United Kingdom, 

 i. 1909, p. 281). 



The proportion in which the total exports from S. Nigeria are 

 distributed to various countries is shewn in the following figures 

 taken from S. Nigeria Govt. Gaz. Extraordinary, July 3rd, 1908,
