In Table V, bakauan (Rhizophora spp.) is represented by the 
largest volume, but Bruguiera parviflora, by the greatest number 
of individuals. Langarai (Bruyuiera parviflora) ranks next to 
bakauan (Rhizophora spp.) in volume, these two trees composing 
86 per cent of the total volume. In this table the greatest 
percentage of volume is contained in the 20- and 25-centimeter 
diameter classes. 
Forester Rafael Medina has made a valuation survey of 3 
hectares between Catubig and Laoang in the mangrove swamps 
of Samar, to show how much merchantable saw timber over 40 
centimeters in diameter can be taken from the mangrove swamps 
in that region. The results are given in Table VI. There was
