PREFACE 



This bulletin is the first of a series to deal with minor forest 

 products. By minor forest products are meant all the products 

 of the forest other than timber, the latter being regarded as 

 the principal product. In the Philippines, as in other tropical 

 forests, the minor products, while of less importance than the 

 timber, are very varied and of great economic value. For this 

 reason, it has been deemed advisable to prepare a series of 

 bulletins dealing with them; particularly as at the present time 

 it is especially desirable to have, in an available form, informa- 

 tion concerning our resources. In preparing a work of this 

 kind there are always points concerning which further informa- 

 tion would be desirable and in the Philippines there is a great 

 lack of data which would be necessary to make the treatment 

 of the minor forest products reasonably thorough. It is believed, 

 however, that the presentation of such data as we have is advis- 

 able particularly as it can then serve as a better starting point 

 for obtaining further information. 



The writers are greatly indebted to Mr. E. D. Merrill, of the 

 Bureau of Science, for valuable assistance and suggestions and 

 to Dr. F. W. Foxworthy, formerly chief of the Division of 

 Investigation, Bureau of Forestry, for extensive records left 

 with the Bureau and for helpful criticisms of the present paper. 

 Without the information obtained from Mr. Merrill and from the 

 records left by Dr. Foxworthy, the preparation of the present 

 bulletin would have been impracticable. The authors are in- 

 debted to Mr. R. C. McGregor for assistance in preparing this 

 manuscript for the printer. 



All plates except VI, VIII, IX, and XXIX are from pho- 

 tographs taken for the writers through the courtesy of the 

 Bureau of Science, Manila, by their official photographer, Mr. 

 E. Cortes.
