50 THE BUREAU OF SCIENCE 



plant for the Philippine General Hospital, the Bureau of Science, 

 and the College of Medicine and Surgery remain unchanged. 



Producer-gas plant. — The producer-gas generator and the gas 

 engine have proved their reliability and economy under intelligent 

 supervision and care. 



Boiler plant. — The two Dutch ovens installed last year in 

 front of the two old boiler units are satisfactory. The arrange- 

 ment produces complete combustion. The improved furnaces 

 produce such intense heat with the present baffling system that 

 no fire brick can stand it for a long time. The baffles have to 

 be repaired every few months to maintain smokeless operation. 

 With intelligent firing the smoke now emitted from the chimney 

 is negligible. The plan that we have used can be advantageously 

 followed elsewhere for the prevention of smoke. The boilers 

 can stand a higher overload now than before the modifications 

 were made. 



Costs. — The average cost per kilowatt hour of electric current 

 was slightly over 10 centavos. This was somewhat higher than 

 during the former year due to the increased cost of coal. The 

 cost of the production of electric current could be considerably 

 reduced by the addition of another producer-gas generator. 



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

 more than 700,000 cubic feet (19,824 cubic meters). The cost 

 of production has been considerably lowered by the use of naval 

 fuel oil in the retorts and dilution with producer gas. 



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

 ing table.

CLEKICAL DrVISION 



The clerical work of the Bureau of Science has progressed 

 and has been a satisfactory tool in the scientific work of 

 the institution. Chief Clerk A. E. Southard returned from 

 his detail as private secretary to the Honorable, the Secretary 

 of the Interior, on February 15 and on March 26 went on 

 leave to China and returned to duty in the Bureau of Science 

 on September 1, During his absence the duties of chief clerk 

 were performed by Mr. C. J. Stancliff, property officer, cashier, 

 and disbursing officer. Mr. Harold Evans was transferred in
