Botanical descriptions are founded chiefly on "A Flora 

 of Manila" ^ by Mr. Elmer D. Merrill, botanist, Bureau of 

 Science, Manila, P. I., and on a study of the plant specimens 

 in the industrial museum of the Bureau of Education. The 

 writer is also deeply indebted to Mr. Merrill for many 

 helpful suggestions. 



Drawings in this bulletin are by Mr. Juan Santos, a 

 student in the University of the Philippines. 



Acknowledgment is due for the review of this bulletin

 the Bureau of Education. In part, the information has

The uses of plants have been determined chiefly by ex-

 the Bureau of Education. 



It is not possible to mention the hundreds of persons 

 whose ideas on different phases of industrial work, as 

 expressed in correspondence with the General Office, Bureau
