As the trends indicated in Table II, are based on one mid-July 
count for each year, the uniform brood appearance for this season 
undoubtedly makes the 1954 count high on a comparative basis. Itis 
believed, however, that the production-breeding population ratios will 
be at least as good as those of 1953. 
Conclusions - 
<= 
It is estimated that the fall flight from Nebraska will be about 
the same as last year.
