of half the evil which would follow such poor proof of so 
important a fact to be determined in the work of a Com- 
mission which seeks to do its work effectively. Then, too, 
why should not the fisheculturist know more nearly and ex- 
actly by sight the whitefish and other commercial fish of 
our great lakes at every stage of their growth, from the fry 
age to that time when their identity can be easily estab- 
lished by the most casual observer? With such knowl- 
edge, we might know with greater certainty the rate of 
erowth of these fish, and we might also be able to definitely 
determine their movements in the great lakes through- 
out the entire year. It would be of interest and a valuable 
addition to our knowledge, to know how long the young 
fish remain upon the spawning beds, and at what period 
they leave them, where they go in search of food, and upon 
what they live after leaving them. These and other mat- 
ters of equal importance challenge the attention of thought- 
ful fisheulturists, who keep in view a successful result of 
their work; and it is clearly not only within the province 
of the fishculturists and of Fish Commissions to settle these 
questions, but it is their clear duty. The successful solu- 
tion of these matters will serve to equip us with valuable 
information that will aid largely in arriving at the best 
practical results at which we aim. 
Greater attention should also be given to the planting or 
stocking of our inland waters, and the manner in which 
this work shall be performed. Systematic and comprehen- 
sive examinations should be made of the lakes and streams, 
to determine their character, temperature, depth and the 
character of the fish food which they sustain. Too much 
stress cannot be laid upon the value of such examination. 
Only by this method of inquiry can intelligent stocking of 
waters be done. The fishculturist who wishes to act for 
the best interests of his work must act intelligently in 
making his distributions. The character of the work in 
which he is engaged and its results depend upon his care
