Sketch shovnng the proposed geographical region* and allUvuiinal sectimi»for the study of 

 the foreM flora of the Philijrpine Archipelago. 



Northern or Luzon 

 region. 



Central or Samar- 

 Paragua region. 



Southern or Mindanao 

 region. 



In applying this plan of work to the Philippine conditions, it is only 

 necessary to use the combination of the type area letter and the tree num- 

 ber, as illustrated above in the detailed report on Dr. Koorders's method 

 of work in Java. This method of studying tropical forests is, I believe, 

 the most practicable, productive of the best results both from an economic 

 and a scientific standpoint, and in the long run probably the most econ- 

 omical which can be adopted in the Philippines. It has been found en- 

 tirely satisfactory after fourteen years of application in the Island of 

 Java, where the forest conditions are very similar to those of the Phil- 

 ippines. 



In closing, I strongly urge that this system be given a thorough trial 

 in the Philippines, by establishing several of these type areas in the near 

 future. Preferably, the first type area should be near the city of Manila, 

 in such a location that it can be easily reached from the city, and for this 

 first type area I believe no better location can be selected than Mariveles, 

 in the Province of Bataan, as here a type area can be readily established, 

 extending from the sea level to an altitude of about 1,000 meters. A 

 type area so established will not only serve to give use accurate informa- 

 tion concerning the forest flora of the vicinity of Mariveles, which is typ- 

 ical of the whole Province of Bataan, but, in the absence of a proper bot- 

 anical garden, will be of the greatest value in assisting employees of the 

 Forestry Bureau to become acquainted with the forest conditions in the 

 Philippines, the characteristics of the more valuable timber trees, etc., 

 and to identify these species in the forest.
