building and other parts of the hospital throughout that period, but none have 

 been discovered within. The numbers recovered outside of the building 

 have diminished. 



During the last year, work has been in progress on still another wing south 

 of the men's pavilion and connected to it by corridors. This new wing is 

 located where the frame house and barn stood. Thorough precautions 

 were taken to avoid permitting termites to get a start in the new wing. It 

 will be noted that this wing is built in part where large numbers were found 

 in the barn cellars. 



The basement of the new wing was constructed with special care to render 

 it proof against entrance by termites. While the building was being construct- 

 ed, an attempt was made to keep boards, beams and other structural material 

 elevated on skids and protected by tanglefoot or by Phinotas oil. The new 

 building is now practically completed and no termite has been discovered 

 within it.
