 dark reddish brown in color. Liusin is one of the woods which 

 has only recently come into use for this purpose. It is very hard 

 and heavy, and pale red to red in color. Luisin piles, placed be- 

 side dungon, seem to last better than the latter. The part above 

 water is more readily subject to fungous attacks. Piagao is said 

 to resist the teredo well, but there is as yet no direct evidence to 

 confirm this statement. None of the above woods are plentiful, 

 especially in sizes suitable for piling.
