Project 3. "Weather observations with reference to frost 

 prediction." 



Professor Franklin. 



As in past years, the United States Weather Bureau has 

 telegraphed daily reports from the district forecaster in Boston. 

 Further study has been made as to correlation of certain 

 meteorological conditions and frost probability. Through the 

 co-operation of cranberry growers, and under financial support 

 from their association, frost warnings are now being sent out 

 whenever conditions necessitate.
