Daily Notes from Field Agent Bairos' Report 



April I, 1910. Went over the situation near the 

 Lava Bed Dredgers demonstrating the use of the spray 

 pump and left one out there for future use. The 

 Company took up the work. Later had the ponds 

 along the river near the bridge oiled. 



April 2, 1910. Inspected the ground above bridge 

 and toward East Side schoolhouse. Found many 

 old mining shafts in the field near the schoolhouse, 

 flagged one in particular for the purpose of demon- 

 strating the methods of destroying mosquito breeding 

 places to the school children ; oiled remainder. 



April 4, 1910. Prepared bottle exhibits of wrigglers 

 for the schoolroom demonstration. Gave chalk talk 

 lecture to school children at East Side and had them 

 visit pond outside of school yard. Took some photos. 

 Continued the oiling of that field in the afternoon. 

 Some school children were found in the field interested 

 in the mosquito ponds.
