112 Thirty-fourth Annual Meeting. 
trout clean may be a necessity since trout can not live in sewers. 
Until we begin getting closer to nature by the clearing out of our 
polluted streams it may be useless to expect to raise trout. 
Under the circumstances it seems to me the highest ambition 
of the modern fish culturist should be the evolution of a trout 
that would be able to live in the tail end of a tannery. 
Mr. Miller: Most of the ponds which I have seen are built 
very much like a window, square at the end, and occupy relative- 
ly the position of the lambrequin in this room. Your gate is in 
the middle of a square end, and there is a dead end across each 
corner. I think this hatchery of White Sulpher Springs has been 
built much in the shape of a coffin, and I think if we would 
build the ponds so the gate would occupy the whole end, and let 
the water come in so that the water would flow out freely, a great 
deal of refuse would be moved which does not now get washed 
out from the pond with the gate in the middle, but collects in the 
corners. 
President: I should like to refer to the plant of the 
American Fish Culture Company, at Carolina, Rhode Island. 
and explain how they manage to raise such a large quantity of 
trout. Their ponds are all lined up with boards, with gravel 
bottoms, all narrow, their widest pond not exceeding 12 feet. 
The ponds where they have the best success are only 7 feet wide, 
with a fall of three inches in 30 feet, and in a pond of that char- 
acter they will rear a thousand marketable trout, three to the 
pound, im a year. 
In other ponds with the ends like those of the United States 
hatchery, with boards across the corners, the water flows very 
rapidly, and there is a long series of those ponds, and they are 
reinforced almost the whole length by driven wells. They are 
very successful there with their driven wells. They have several 
4 inch driven pipes there that will flow six inches over the top 
of the pipe. It is remarkable on that account. They keep their 
breeding trout in these long narrow ponds, and have no trouble 
at all. There never has been any fungus there, no disease at all. 
Their trout are all fed regularly on hog’s plucks, ground up, 
hearts and everything all together. 
They had a man there who had an idea that these ponds were
