Islands is a careful application of scientific knowledge. We 

 should collect full information as to what variety of cane is most 

 desirable to plant. One variety is noted for its sweetness, an- 

 other for the size of the stalk, and so on. The results obtained 

 from different varieties in their home countries are often dif- 

 ferent from those in other lands. It frequently happens that a 

 given variety does well only in one kind of soil and in a given 

 climate. The various problems in cane culture can be solved 

 only by careful experimentation with chemical analyses of the 

 soil and of the cane, etc. The Government sugar laboratory is 

 appealed to in cases of dispute between sugar growers and mer- 

 chants as well as for ordinary polarizations. 



GEOLOGY AND MINES 



The larger part of the time of the geologists of the Bureau 

 of Science has been devoted to engineering geology, economic 

 geology of metallic and nonmetallic minerals, geologic recon- 

 noissance and topography, and geologic mapping. The geology, 

 field relations, and economic aspects of coal, asbestos, gold, sul- 

 phur, petroleum, artesian water, road metal, iron ore, building 

 stone, soils, raw minerals for clay products, Portland and na- 

 tural cement, and lime have been studied. Our geologic exam- 

 inations have assisted in the selections of sites for engineering 

 structures. Geologic examinations and the correlation of ar- 

 tesian well core samples have aided in the location of drill sites. 

 Statistics of metallic and nonmetallic minerals are regularly 

 collected. The work of the geologists is extremely practical and 

 the work in delimiting the economic resources could be greatly 

 extended advantageously. 



The information that the Bureau of Science now possesses 

 with regard to the industrial, economic, and sanitary develop- 

 ment of the Philippine Islands is not sufficiently used. The 

 facilities of the Bureau could be made more inclusive if in- 

 dividuals would submit to it more of their problems, and it has 

 been the aim of the Bureau in its communications to the press 

 to show that the greatest assistance can be rendered to manufac- 

 turers and others who bring their problems. In general, the 

 Bureau endeavors to be of the greatest possible assistance to 

 manufacturers, producers, miners, planters, and public-health 

 workers by making reports and giving expert advice on crops, 

 soils, fertilizers, plant diseases, insect pests, mining, etc., and in 

 performing analyses and examinations of sugar, soils, fertilizers, 

 waters, coal, metals and alloys, gums, resins, minerals, cement, 

 food products, biological and pathological specimens for practi-
