APPENDIX 10 

 Report on the Canal Zone Biological Area 



Sir : It gives me pleasure to present herewith the annual report of 

 the Canal Zone Biological Area for the fiscal year ended June 30, 1952. 



BUILDINGS AND EQUIPMENT 



Construction of the new 2-story laboratory begun last year was 

 completed. The entire ground floor is now of reinforced concrete, 

 extending 5 feet beyond the building on all four sides. The ground 

 under the concrete was treated with sodium arsenite, as a protection 

 against termites ; all four sides were walled in with terra-cotta blocks 

 faced with cement; and the building was surrounded by a concrete 

 ditch. The lower windows are in aluminum frames, and all windows 

 are provided with plastic screens. A photographic dark room, 15 x 11 

 feet, is included. Two laboratory rooms, 15 x 23 feet, were built, each 

 to accommodate two to four scientists. These rooms will be provided 

 with beds and dressers, and it is hoped to install dry closets in each. 

 Funds to install sinks, work tables, and shelves will need to be supplied 

 later. 



The ground behind the building was leveled and a pit dug for an 

 additional concrete water tank to store the runoff from the roof of the 

 building. Since this reservoir is urgently needed, it is hoped that 

 it can be completed during the next fiscal year. 



The ground floor of the zinc-meta-arsenite building, just below the 

 main laboratory building, was covered with reinforced concrete and 

 will be available for laboratory use. The building has two rooms, 

 each with a separate entrance, which will comfortably accommodate 

 two persons in each room. The lower floor of the main laboratory 

 has been cleared of miscellaneous storage material, and this has 

 about doubled the available working space for scientists. 



The library and herbarium now in the Haskins building are being 

 transferred to rooms on the upper floor of the new building. When 

 this change is completed, the kitchen equipment will be moved into 

 the larger, fireproof Haskins building. The toilets and showers, 

 now in the main laboratory building, will then be moved into the 

 old kitchen building. 



The large main building, which accommodates six persons, is in 

 satisfactory general condition but will soon need repairs to screening
