These figures show tlie hulk of dipterocarps to he not so high here as 

 in some other forests, yet the preponderance of that family is still too 

 apparent to he overlooked. 



The following, giving some idea of the composition of the forest, is 

 a list of the principal trees other than those mentioned in the yield and 

 stand tables :

i'OKESTS OF LEYTE, MIXDORO. AND VARIOUS PARTS OF LUZOX, AKD 

 MINDANAO. 



Eough estimates of timher made in the Davao District of Mindanao 

 show also the predominance of dipterocarps. On the Island of Samal 

 near Davao, at least 80 per cent of the volume of the forest is composed 

 of dipterocarps, mainly Pentacme contorta Merr. & Eolfe, Parashorea 

 plkata Brandis, and Shorea guiso Blume. Untouched forests on the 

 mainland at the head of Davao Gulf showed the dipterocarp forests reach- 

 ing to the tide-water in many places and even occupying all but the 

 frontal zones of the beaches. 



The above represent regions in which more or less detailed studies 

 have been made by the author. More hurried trips made in the Provinces 

 of Tayabas and Camarines on the Island of Luzon, in the District of 

 Zamboanga on the Island of Mindanao, and on the Island of Leyte, show 

 that the large bodies of forest are composed of dipterocarps in greater 

 or less proportion usually running over on an average 70 to 80 per cent 

 of the bulk. The published work of Merritt* for Mindoro and the 

 unpiiblished results of Curran, Hagger, Klenime, and other foresters in 

 the Bureau of Forestry for various parts of the Island of Luzon, of 

 Hutchinson for parts of Mindanao, and of Eosenbluth for northern Leyte, 

 give results in entire confirmation of those mentioned above.
