100 Thirty-fourth Annual Meeting. 
Mr. Titcomb: I do not wish to intimate that all these fish 
diseases are beyond the possibilities of the scientist, but an ounce 
of prevention is worth a pound of cure; and in the Adirondack 
Lakes the prevention means to stop the deforestation and stop 
pollution. In the face of the evils resulting from deforestation 
and the pollution of waters, science is helpless. On the other 
hand, in connection with the hatcheries and all over this country, 
in connection with practical problems of fish culture, the scientist 
is needed. There is enough to do to keep all of the scientists 
of the country, including those who are traversing the country on 
less important missions, on practical problems of this character 
for years. 
Mr. Atkins has given an admirable paper on one of the 
problems, to-day. This question of suckers should be taken up. 
Who knows whether the sucker is really a detriment to the fish 
pond? Who is positive of it and can prove it? We may say 
that it is a case of the survival of the fittest. If the pond is 
better for trout than for suckers, the trout will survive. On the 
other hand, if, owing to deforestation or pollution, it is more 
suitable for the sucker, he survives the trout. 
Mr. Whish: I do not want this thing to stop here. There 
are men right in this room who know about this matter. I 
have had letters from some of them. The reason | presented 
that paper was not because | know more about the subject than 
others, but because I knew something about it in our own 
state. Weare in trouble there and we are here to confess it; and 
we want some other gentlemen, who have had trouble of the same 
or similar kind, to tell us about it. If we are going to have an 
experience meeting, let us give our experiences, and if we cannot 
do that, let us pray. (Applause. ) 
Mr. N. R. Buller: I would like to ask, what have you been 
accustomed to feeding your trout at your hatcheries ? 
A. Nothing but liver. 
Mr. Buller: I think that is one of the causes of the parasitic 
growth. 
Mr. Whish: So do I, but you cannot get our hatchery fore- 
men to think so.
