36 THE BUREAU OF SCIENCE 



Reserve stock of the Philippine Journal of Science. — Collation 

 of 75 reserve sets of the Philippine Journal of Science has been 

 completed. Additions to this stock are now examined before 

 reaching the library, so we can be reasonably certain that 

 volumes of this publication sold or sent in exchange are complete. 



Exchanges. — On account of the necessity for the strictest 

 economy, little effort has been made to increase the exchange 

 list of the Philippine Journal of Science. Valuable gifts and 

 exchanges sent in return for the Annual Report of the Director 

 of the Bureau and for Mineral Resources have added important 

 publications to the library. 



Library training. — During the college year 1913-14, two or 

 three recitation periods were given to the five-year students in 

 the College of Medicine and Surgery of the University of the 

 Philippines to familiarize them with the Index Medicus. This 

 work has been extended during 1914-15 to include from 8 to 

 10 recitation periods and, in addition, elementary work has been 

 given in the use of the library shelf list, dictionary catalogue, 

 and union catalogue, and in the use of reference books. Twenty- 

 three students, each receiving one lesson per week, are enrolled 

 in this course. The librarian of the Bureau of Science also 

 cooperates in a course in library training offered by the College 

 of Liberal Arts of the University of the Philippines. 



ENGINEERING DIVISION 



Since September 10, 1908, the engineering division has been 

 entirely Filipinized. There have been no important changes in 

 the direct supervision of the power plant during the period 

 covered by this report. Mr. Jose Guerrero y Reyes remains as 

 chief power engineer and Mr. Felix V. Valencia was appointed an 

 assistant engineer on April 1, 1914, to relieve Mr. F. R. Ycasiano, 

 who has drawn the plans and supervised the reconstruction of 

 the Bureau of Science boiler units and is taking up the more 

 important work of the mechanical and testing engineering which 

 has been planned for several years. 



Power plant. — The function of the central power plant for 

 the Philippine General Hospital, the Bureau of Science, and the 

 College of Medicine and Surgery, which is under the direction 

 of this Bureau, was fully described on page 91 of my Twelfth 

 Annual Report. The addition of a Dutch-oven furnace to the 

 new boiler installed in 1913 has been a great success, and with 

 this system we have obtained a saving of 2.82 per cent in the 

 consumption of fuel. Under ordinary load it produces prac-
