Uses 
The figured material is usually converted into veneer for use in decorative 
work, such as cabinet work, paneling, interiors of railway coaches, ships' 
fittings (cabins on the Queen Mary), and lighter types of furniture. The 
plain stock may go into lumber or ordinary plywood and joinery. There is less 
demand for the wood as lumber because of the cross breaks and irregularities 
of growth (1, Ik, 16, 22, Zk) . 
Pulp from the light-colored avodire yields paper that compares well with paper 
obtained from the ordinary commercial hardwoods (7). 
Supplies 
In the past, the Ivory Coast has been one of the main sources of log supply, 
especially of figured material, because logs are conveniently transported to 
seaports from this region. Overland transportation of logs has been poorly 
developed. More recently, the Gold Coast has become another of the main sources 
of log supply (1, 16, 2j?). Avodire is not available in large amounts, but logs 
were imported before TV or Id War II with average girths of 5 to 6 feet and lengths 
up to 15 feet (16). The logs first entered the French markets soon after World 
War I, and not until 1923 was much shipped into German markets. Several years 
later, it attracted notice in England and America (22).
