such streams and wish to stock them, is to dig deep holes in 
the smal] streams such as are convenient to their places. Dig 
a hole which.will have a curve in it, with no square shoulders 
in it. {f would put something in the stream where fish could 
hide—logs or brush—so that they could have some sort of 
cover. One great thing in stocking streams is to be careful 
not to put in too many fish. You must govern yourself in 
stocking streams as you would in putting cattle into a pas- 
ture, or more will die than live. The food that the fish live 
upon must also be taken into consideration in stocking the 
stream. In putting spawn into a pond and allowing them to 
hatch there soon after impregnation, these spawn would not 
hatch unless there was a spring directly under them. If there 
was a spring and they were placed in carefully, the spawn 
would hatch, but if there was no spring to carry off the sedi- 
ment as it came up through the gravel the sediment would 
kill the spawn. 
As to percentage of loss mentioned in Mr. Porter’s paper, 
it was not larger than was generally supposed. In old times 
such a loss was possible. I kept this year only one thousand 
young trout, and I raised 75 per cent. until they were a year 
old. The great thing is to have cleanliness in the apparatus 
you raise the fish in. All food thrown in for the fish to eat 
that is not consumed goes to the bottom, and there it becomes 
foul, and the fish soon sicken, and when they sicken they 
die. The way to prevent this is to keep your troughs clean. 
My troughs are cleaned every day perfectly clean, and. during 
the last few years we have made a great success in raising 
our fish. 
_ Tue Prestpent: Mr. Green, Mr. Porter states that only 80 
to 85 per cent. of all the eggs will be impregnated. 
Mr. Green: I think we can do better than that. We
