BEE CULTURE. 
E. F. Pamtres, In Charge. 
E. F. Phillips attended a meeting of the farm demonstrators of North Carolina at Raleigh 
on August 21 and 23 for the purpose of arranging for a new line of work soon to be undertaken. 
It is planned to make a survey of the State for the purpose of determining the possibilities of 
building up beekeeping and to test out, in cooperation with the county agents, various lines of 
extension work. E. G. Carr, deputy State apiary inspector for New Jersey and a director of 
the National Beekeepers’ Association, has been appointed to do the field work on this project 
and will begin work on October 1. Mr. Carr has had extensive experience as a practical bee- 
keeper and has served as inspector for several years. 
In connection with the wintering investigations, tests are now being made of the thermal 
conductivity of various double-walled hives and of the coefficient of transmission of heat of the 
various parts of the hive to determine the best methods for constructing such hives,
