of surface, a very important feature to be considered, as the bad 
eges if crowded, would cause the good ones to float by mingling 
with them. 
Quite an extensive use of this method has shown no deleter- 
ious effects, and where there are over a thousand dead eggs in the 
basket at the time the empties are turned the use of the salt solu- 
tion will result in a saving of labor. 
DISCUSSION. 
Mr. Whish: ‘This is an entirely new suggestion, so far as 
I am concerned, and if, as suggested by Mr. 'Titcomb, this meth- 
od can be apphed to brook trout eggs, we can save much time 
and labor in our hatcheries. If Mr. Clark has had any practical 
experience with it in handling lake trout eggs, I should like to 
hear from him, because we have been paying particular atten- 
tion to lake trout during the past two years, in our state, and 
will pay more attention hereafter. If we can save time and la- 
bor, it will be of great value. 
Mr. Clark: I am perfectly willing to give my experience 
with the salt solution, as far as | have gone. I have not how- 
ever, done enough to arrive at any positive, definite conclusion. 
I really think it is of no value whatever so far as lake trout 
and brook trout are concerned, and I will give you my reasons. 
But still, as I say, it may be that I might change my views after 
another season’s work with the lake trout. In order to be val- 
uable it must do the work before the eggs are at 450 temperature 
units development; because at that time it would take longer to 
pick the eggs out of the trays in the troughs or baskets, (if you 
hatch them that way), and prepare, put them in the solution 
and wash them up, than to handle the trays and pick the eggs 
out. But at that time there is not one per cent of bad or unfer- 
tized eggs in the tray. So unless this method can apply before 
what we call the eyed stage, with 400 and over temperature 
units, we cannot use it with lake trout. 
I know from the experiments that we could do nothing 
with this method in what we call green eggs—the bad eggs 
would not rise. That is why I say, as far as I have gone, it 
is of no value to us, because after the eyed stage it will take more
