extent during the continuance of hostilities. However, even since 

 the war began, individuals have done work for the Bureau of 

 Science when the^ were on furlough from the firing line. The 

 Bureau of Science has been particularly fortunate in being able 

 to derive much aid from the world science program, and any 

 interruption of it affects this institution, for less general work 

 applicable to the Philippine Islands is carried on. It is gratify- 

 ing that during these disturbed times the Philippine Journal 

 of Science has been so fortunate as to have a slight increase in 

 its paid subscription list. 



POWER PLANT 



There has been no change in the personnel or in the func- 

 tions of the central power plant for the Philippine General Hospi- 

 tal, the Bureau of Science, and the College of Medicine and 

 Surgery. 



• Costs. — The electric current generated and delivered at the 

 switchboard is 240,701 kilowatt hours, at an average cost per 

 kilowatt hour of 1*=0.077, which is considerably less than for last 

 year. This is due to the fact that the producer-gas plant and 

 gas engine were operated almost continuously during the greater 

 part of the year. During the last month the gas engine was 

 operated for one week only, on account of the lack of suitable 

 coal. Had it not been for this, the average cost per kilowatt hour 

 would have been still lower. The total amount of steam gen- 

 erated in the boilers is 6,934,840 kilograms, at an average cost 

 of ^=0.00303 per kilogram. 



Mansfield gas-generating plant. — The total gas generated was 

 nearly 750,000 cubic feet (21,098 cubic meters). 



Shop. — The number of shop requests is shown by the fol- 

 lowing table :
