Works readily, but contains quite a large amount of salt and, conse- 
quently, is said to cause nails or spikes to rust quickly. Shavings salty 
to the taste. Air-dry wood sometimes contains as much as 1 per cent 
of its weight of salt. In some parts of Borneo the natives secure salt 
from the ashes of the wood. Used for house building, planking for 
boats, wall plates, bridges and all parts of structures which come in 
contact with metal work ; used also for telegraph and telephone poles. It 
should be tried for railroad ties. The air-roots of this tree are very corky 
and light. They are commonly known in the Philippines by the name 
of daluru and are used as razor hones. (See p. 427.)
