 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 >all 

 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 lies. The air-roots of this tree are very corky 

 and light. They are commonly known in the Philippines by the name 

 of dalura and are used as razor hones. (See p. 427.)
