be grown more widely in the British Isles for posts, ke. Trees up 
to 40 or 50 years of age would probably be more useful than 
older trees. See also A.B. 1911, p. 219. 
Persimmon (Diospyros virginiana, L.). 
Forr1cn.—Eastern N. America. 
The wood is used extensively for weaving shuttles and bobbins, 
and is said to make a good substitute for box. 
Greenheart (Nectandra Rodivei, Schk.). 
Britisn.—British Guiana. Forrzan.—Brazil. 
The timber is very hard and durable. It is highly esteemed 
for use in brackish water, and is perhaps the most widely used 
timber for piles for wharves, dock gates, kc. It is also a favourite 
wood for fishing rods. The wood of the Bullet Tree (J/¢musops 
globosa, Gaertn.) is said to be sometimes used as a substitute, also 
the wood of Quebracho Colorado (Quebrachia Lorentz, Griseb.). 
Satin Walnut (Liquidambar styraciflua, L.). 
Foreicn.— United States of America. 
_This wood is used extensively in the manufacture of the cheaper 
kinds of bedroom furniture. It has also been used for paving 
blocks, but warps badly in seasoning, and is worthless for the 
purpose, 
Quebracho (Quebrachia Lorentzii, Griseb.). 
Forercn.—Argentine Republic. 
The wood is very strong and durable. It is used for heavy 
building work, sleepers, piles, dock timber, and can be substituted

Mahogany (Swietenia Mahagoni, L., S. macrophylla, King, 
and Khaya spp.). 
Britisu.—West Coast of Africa. Forrrgn.—U.S. America, 
Cuba, Hayti, San Domingo. In 1913, 80,995 tons of mahogany, 
valued at £666,297, were imported from the following foreign 
countries: Germany, German West Africa, French West Africa, 
United States of America, Cuba, Hayti, and San Domingo. From 
the following British Possessions 60,806 tons, valued at £559,582, 
were imported: British West Africa, Gold Coast, Southern 
Nigeria, British West Indies, British Honduras. The mahogany 
from West Africa is usually the timber of species of Khaya, and 
although it is generally inferior in beauty and value to the wood 
of Swietenia Mahagoni, it makes handsome furniture and shop 
fittings, and is valuable for panelling, &c. There appears to be 
room for an increase in the trade of West African aide generally.
