The trees measured in Table XII were cut by six laborers, 


each working three hours a day for four days; those in Table 
XIII by four laborers working two to three hours a day for 
four days; and those in Table XIV by four laborers working 
half a day for three days. 
The results in Tables XII and XIV were obtained from planta- 
tions 7 years old. The total volume in each on 0.1 hectare was 
9.2 cubic meters. The trees recorded in Table XIII were 8 
years old and showed a volume of 14.7 cubic meters on 0.1 
hectare. The volume of stacked rajitas was in every case much 
greater than the volume obtained by measuring the trees. 
This 
difference was caused by the space occupied by air spaces. 
MARKETING OF BAKAUAN 
Manila is the market place for most of the bakauan grown 
around Manila Bay, and transportation is naturally by water. 
The firewood is loaded into cascoes which are towed to Manila 
by launches. The charcoal is loaded on the regular steamer and 
pays a freight charge of 5 centavos per sack.
