old plans; and with that we have the attendant conditions that 
come from filth and uncleanliness. 
Now I have had an experience as a bass fisher, which may be 
interesting in connection with this subject. There is a slaughter 
house near our city, Dayton, the drain of which empties into one 
of our little streams. The water is cold and apparently pure, 
and teeming with minnows. Now we can go out into our clean 
running streams and catch our minnows free from disease, put 
them in a tank with running water and preserve them. I had in 
my dooryard a tank 12 x 4 x 6, into which I could put several 
thousand minnows, and if healthy when put in they always did 
well. But when we went up to the pool where the blood from 
the slaughter house drains, it was very easy to catch minnows, 
and on one occasion we caught two bushels apparently healthy 
minnows. But as soon as you would get them, if you would 
handle them the least bit they would develop a fungus disease. 
I have looked in vain through all our city hbraries and every- 
thing accessible to me to find any treatise on diseases of fish, and 
never found anything at all. 
Mr. Whish: ‘There isn’t anything. 
Dr. Greene: ‘These minnows were fat and sleek, looked nice, 
everything looked favorable,* but they had fed on the slaughter 
house, and they were diseased and infected, and developed this 
fungus disease. 
Whenever you touched one of them and took off the pro- 
teetive shime, fungus would appear, the fish would swell up, a 
blood blister would appear which would burst, an open sore 
would develop and the minnow would die. 
There is no doubt but that the disease Mr. Whish complains 
of, is the result of infection. 
Mr. Talbott: Mr. President, permit me to make a sugges- 
tion which if not practical is at least logical. 
There is in Paris a class of men who spend the greater part 
of their lives in the sewers and these men it is claimed are not 
only long lived but healthy beyond the average, yet 1t would seem 
wasted effort in training a child for such a career to insist on a 
degree of cleanliness that must needs be neglected in its after 
life. So the strenuous efforts of our fish culturists to raise the
