 as compared with 2,061 drawings in the preceding year, the bulk of 

 the work being accomplished by four draftsmen. The increase of

The commodious and easily accessible quarters into which the 

 Section of Illustrations recently moved have greatly contributed to 

 the increased efficiency and output of work. 



In the photographic laboratory a total of 138,832 pieces were 

 prepared, as compared with 112,272 pieces during the preceding 

 year. Over 2,000 negatives were made in the field for various 

 offices and the results obtained in technically correct photographs 

 fully justified the expenditure.
