PHOTOGRAPHIC LABORATORY. 



Owing to lack of space at the quarters of the Bureau of Forestry, 

 the photographic laboratory remained, as alread}^ mentioned, until 

 recently, iu the building of the Bureau of Chemistry, through the 

 courtesj^ of the chief of that Bureau. With the acquisition of the 

 eighth floor of the Atlantic Building it was possible to assign sufiicient 

 quarters for the equipment of a photographic laboratory. The work 

 of installing the equipment is now completed. An enlarging and 

 reducing camera of large size was purchased, and the laboratory is 

 now thoroughly equipped in all branches of photographic work, includ- 

 ing map pliotograph}^ enlarging, reducing, and wet-plate work. 



The work of the laboratory during the j^ear was very satisfactory. 

 Five thousand three hundred and thirty-two films and plates were 

 developed, 9,(595 prints were made, and altogether 20,884 items of 

 work were performed. 



INSTRUMENTS AND SUPPLIES. 



Instruments. — The rapid extension of the work of the Bureau in the 

 field made heavy demands for additional instruments, while experience 

 in the woods suggested improvements in the construction of several 

 types. A very small percentage of field equipment was lost or dam- 

 aged beyond repair, for the members of the field parties were generally 

 careful in the handling and use of the instruments. The total expendi- 

 ture for instruments during the fiscal year was §7,245.61, or 3.9 per 

 cent of the total appropriation.
