The ratio of adults to juveniles for all species for each year of the 
census is as follows: 


1937 1938 1939 1940 1941 1947 1948 
1:3.9 1:2.2 1:3.4 1:1.5 1:2.7 S22 1:4.0 
1949 1950 1951 1952 1953 1954 1955 
- 1:2.7 1:2.8 1:3.4 1:1.6 1:2.9 1:2.8 


The ratio of juveniles to adults was about averape. Compared to the 
previous year the adult population was down for all species except mallard and 
baldpate. 
Summary 
There was a tremendous growth of vegetation in all areas this year as 
compared to the last three years. Vegetation in Mud Lake and the Third River 
‘area account for an inaccurate census. Low water levels last fall and gradual 
raising of water levels this spring probably account for the growth of vegetation. 
From the data, we had a decrease of 58 percent compared with 1939 to 
1940 census which was considered as par for the area and a six percent decrease 
over last year; considering the inaccurate census of the Third River and Mud Lake 
areas, itis believed that the population should show an increase over last year.
