eggs in clusters collected this year in southeastern Massachusetts was 
smaller than the average for those collected in the 37 towns would in

kuvanae at least can be explained by the fact that the climatic conditions 
are more favorable for its increase in southeastern Massachusetts than in 
other parts of New England."
