I could list many cases of wasted or ill directed 
effort that could have been prevented and also many 
unsolved problems. A scientific study of Douglas Lake, 
Wisconsin, showed that during August there was insuf- 
ficient oxygen below the thermocline at about thirty feet 
to support fish life but thousands of deep water fish had 
been planted there in an attempt to establish such species. 
In fact very few attempts have been made to gather data 
that can be used in planning for the future of our wild 
life and most measures have been taken in a haphazard 
way. 
The scientific man has an immense amount of impor- 
tant work ahead of him in this line, in investigations, 
experiments and education. Why does one game bird 
respond to protection while another increases scarcely at 
all under absolute protection? To what point may we 
allow the killing of the males of our big game animals? 
How can we save losing millions of ducks by alkali 
poison? In some waters trout thrive wonderfully while 
in others they do not. What governs this and how can 
we increase the productivity of our fish waters? There 
are many such questions and thousands of dollars will 
be wasted until we can make such investigations as will 
enable us to answer them. 
When the scientific man takes an active interest in 
such problems and can cooperate with the sportsmen to 
enact laws and undertake plans of management based 
on correct biological principles, a great step in advance 
will be made in providing the opportunity for our sons 
to enjoy the rich heritage of wild life which has been 
ours.
