106 Thirty-fourth Annual Meeting. 
Now where there have been new stations established, start in on 
the plan of following nature as near as.possible, otherwise the 
brook trout will pass away. 
Mr. Atkins: I want to second Mr. Clark’s suggestion, and 
add emphasis to it, that what we need above all things is to fol- 
low nature more closely, and try to get away from artificial 
methods as far as possible. 
Mr. Joslyn: It has been a sort of hobby with me for the 
last two or three years, that if we wanted to raise trout success- 
fully, (and for that matter, most all kinds of fish, but particu- 
larly trout) we must follow nature. Building a pond as large 
as this room with no live water flowing through it so far as I 
have observed, is not in accord with nature. When I was a boy 
living in the state of Vermont, I noticed that all the streams that 
I went fishing in had fresh water with here and there a pond, 
and an eddy, or a hole under the bank in which the big trout 
would, he. But except when they were quiet those trout were 
in the swift water, hunting for their food. It is my belief that 
if you are going to get rid of disease, you have got to give your 
brook trout fresh, running water to live in and swim in; and 
look after their food carefully. The remarks which Dr. Evermann 
made in regard to feeding, I believe are absolutely correct. I 
have seen ponds in which it would seem a mystery that fish could 
live, without the bottom being cleaned. | believe what we are 
after can be secured by a return to cleanliness, by a return to 
nature’s methods. 
Just think of the city of Havana. Year after year it was 
decimated with yellow fever. Now they have cleaned up the 
town, they have put sewers in, their refuse is carried out of the 
city, and there is no more yellow fever to speak of. Why should 
we not have these diseases in our ponds of stagnant water? 
Although you may run fresh water in, it is not the live water 
that you see in your mountain streams. Why should we not have 
disease from the filth lying on the bottom of ponds? These 
parasitic diseases are essentially filth diseases, and their preven- 
tion lies in a return to cleanliness and nature. 
Mr. Marsh: ‘There are one or two possible remedies for these 
big epidemics, which might work if the fish culturist was willing
