With the population of geese dealt with in this report, it is

of geese in Canada, because much of it is virtually necessary 
for the survival of the native Indians. 
In 1944 and 1945, when season limits were imposed for 
Alexander County, it was a relatively easy matter to limit the 
Fane Of geese in the Horseshoe Lake area to a predetermined fig- 
ure, due to the facility with which the day-to-day kill could 
be tallied. The season bag limit in the above instances was 
determined by the trend of the population in prior years, but, 
to be fully effective, management should anticipate future 
trends based upon the current composition of the population. 
With the data at net on the Canada goose in the Mississippi 
Flyway, it is possible to arrive at a pracviea” estimate of the © 
maximum kill that can be tolerated. 
Since the fall flicht in any year depends to a large 
extent on the production of young in the spring of that year, 
to predict the flock population with reasonable accuracy, it 
is necessary to know the trends in numbers of breeding females 
and to have some measure of the nesting success on the breeding © 
grounds. Inventory on the latter is not. easy because of the | 
nature of the terrain, but the use of planes aids tremendously 
in such work. For the present. and until more data are availabl
