FOURTEENTH ANNUAL REPORT 29 



Islands, and will be the basis for further industries in the Phil- 

 ippine Islands. One year ago Doctor Brill began work on gar- 

 denia, but owing to the lack of material it was discontinued. It 

 is expected that sufficient flowers will be available this year to 

 carry on the work. At present all perfumes sold as gardenia 

 are artificially prepared, and there may be an excellent opportun- 

 ity for the cultivation of the flowers in these Islands. There are 

 many other flowers that are available for cultivation for per- 

 fumery in the Archipelago. These will receive study by the 

 Bureau whenever quantities large enough to justify an invest- 

 igation can be obtained. 



Beriberi has been extensively studied by the Bureau of Science 

 in the past, and many contributions with regard to the etiology 

 of this disease have been published in the Philippine Journal 

 of Science. Active study of this disease is not now in progress 

 owing to lack of men. However, quantities of tiqui-tiqui extract 

 for free distribution through the Bureau of Health under Act 

 No. 2376 for the alleviation of infantile beriberi are now being 

 prepared, as pointed out on page 10. 



An article on papain shows conclusively that gum made in the 

 Philippines is equal, if not superior, both regarding color and 

 activity, to any now on the world's market. It is a good com- 

 mercial proposition, provided a limited market is not flooded. 



As material for paper becomes scarcer and more difficult to 

 procure, it is increasingly apparent that the Philippine Islands 

 are to play a larger part in furnishing a supply of the raw 

 material. The Bureau of Science has investigated the suitability 

 of the waste from abaca, or Manila hemp, cogon grass, and 

 various other substances for paper pulp. Investigations by the 

 Bureau have demonstrated that bamboo can be made into a high- 

 grade pulp and that it will help to overcome the scarcity of the 

 raw material for paper. So much interest has been shown that 

 sales of the number of the Philippine Journal of Science contain- 

 ing information on this subject have exhausted the stock. A re- 

 print of the article on Philippine fibers and fibrous substances 

 and their suitability for paper making with regard to bamboo 

 pulp has been made. 



The Bureau of Science will very soon publish a preliminary 

 article on the destructive distillation of waste woods of various 

 kinds and the products obtained as a result of this distillation. 

 This investigation should assure the utilization of the waste 

 wood of the Islands. The resins and resinous woods have been 

 investigated, and it has been shown that these are very similar 

 to those from the same types of trees in the United States and
