The Government of the Philippine Islands, 



Department of the Interior, 

 Bureau of Science, 

 Manila, July 15, 1913. 



Sir: I have the honor to present a resume of the researches 

 of the Bureau of Science and of the work performed during the 

 fiscal year ending June 30, 1913, together with a few recom- 

 mendations regarding improvements which seem to me to be 

 necessary. 



The Bureau of Science was established as the Bureau of Gov- 

 ernment Laboratories on July 1, 1901, by Act No. 156 of the 

 Philippine Commission, although actual chemical and biological 

 work was first begun on September 25 of the same year when 

 it was started with 6 employees in a rented house on Calle Iris, 

 Manila. The photographic collection, which has developed rap- 

 idly and now includes some 15,000 negatives, and other photo- 

 graphic work were begun with the employment of an official 

 photographer on November 16, 1901. Entomological investiga- 

 tions began on December 9, 1902, and with them the foundation 

 of the present entomological collection of specimens. On Jan- 

 uary 1, 1903, the serum laboratory and the grounds at San 

 Lazaro were transferred to the Bureau from the Board of 

 Health. The section of botany which had been organized in the 

 Bureau of Agriculture and the nucleus of the herbarium were 

 added on July 1, 1903. On November 1, 1905, the Bureau of 

 Mines ceased to exist and became an integral part of the Bureau 

 of Science, and on November 1, 1906, the Ethnological Survey, 

 formerly the Bureau of Non-Christian Tribes, which before that 

 time had been incorporated with the Bureau of Education, was 

 transferred to the Bureau of Science, and, as the division of 

 ethnology, has undertaken the preliminary organization of the 

 Philippine museum and has secured sufficient material to fill 

 three-quarters of the space in the building assigned to it on Calle 

 Juan Luna, one-quarter being reserved for the exhibit of the 

 Bureau of Forestry. The collector of natural history specimens
