Success of the Season 
Success of the season is presented in Tables II and VI inclusive. Broods per 
Square mile show a general decrease from previous highs, however, production 
was better distributed thorughout the season. The hatch was generally earlier and 
as birds were much more widely distributed than in past years we must interpret 
the data to indicate an increase of 10 to 20 percent in production for the current year. 
Goose broods show a modest decrease. Geese were more widely scattered 
and we believe the production to be the same as last year.
