The dotted line represents a sample of 87 indi- viduals from the first group, tagged in November of 1947. The solid line represents 1,799 individuals from the second group, tagged during the 1949 1950 season. The third and final group was generally similar to the second in all respects, excepl for being tagged the following season. 1950-1951. H contained about 2,000 fish. Up to llic present time (January, 1952) tag returns from these three groups for which date and place of capture are known total roughly 400. Each return is plotted as an individual mark on one of the accompanying series of six charts | Figures 5 to 10) showing where tagged fish were caughl during successive calendar periods. The groups are represented by differenl symbols, as indicated in the legend in the first chart: group one by crosses, group two by circles, and group three by squares. The juveniles are shown by half-dark symbols in each case. The arbitrary selection of 20 inches as a dividing line between juveniles and adults is actually an oversimplification, because the males mature sexually at a much smaller size than this. However, it is entirely satis- factory for the purpose at hand. The first chart in the series of six shows recaptures during the winter and early spring soon after tagging. Numbers are small because fishing is always relatively poor at this season ; the bass do not bite well when the water is cold. Also, fewer tagged fish were available to the fishermen than later, for large numbers were released subsequently during April and May. There is little indication of any movement away from the tagging locality during the winter,
