Conclusions 
According to the survey data collected it is anticipated 
that the fall flight from southern Manitoba will be considerably 
less than in 195% but just slightly below the average for the years 
1954 - 1958. The low number of broods and ponds is balanced by the 
fact that the hatch was continuing at the time of the survey. However, 
two factors should be borne in mind when appraising this forecast. 
The first is that broods and adults were more easily seen under the 
drying conditions than in former years. The second is that Manitota 
apparently has received a temporary increase in breeders as the result 
of intense drought in southern Saskatchewan. The increase received 
in 1958 apparently did not produce enough to sustain itself, and in 
all likelinood will not do so tnis year.
