iv, and if anyone has had any other experience we would like 
to hear it, and also would like to hear from Mr. Stone, who has 
had considerable to do along this hne. 
Mr. Carter: I do not mean to infer by what I read that I 
doubted Mr. Stone’s statement that he separated his eggs. I 
know that he did succeed in separating them in jars at Swantan 
and West Milton also, but it was impossible for me to do so. 
Mr. Titcomb: I would hke to have Mr. Stone explain how 
he did it. He is our expert on sturgeon, I believe. 
Mr. Stone: The few sturgeon eggs that we took and suc- 
ceeded in hatching we treated the same way as we usually treat 
pike-perch eggs, by using mud, sand, muck, or something of that 
kind; we did not have any difficulty in separating them when we 
treated them in the way we did pike-perch eggs. In fact we 
had no trouble with them whatever. We put them in jars and 
they hatched out all right. 
I do not think there need be any trouble about hatching 
sturgeon eggs if you can get them impregnated. ‘The trouble is 
to find a female and male at the same time so that you can have 
milt to impregnate the eggs with. I have hunted sturgeon for 
many years in Lake Ontario, Lake Champlain, Missisquivi river 
and Lamoille river the Delaware river and Delaware Bay, and 
the only place that I know of anywhere in the country where you 
can get sturgeon eggs and impregnate them, is in the “Sturgeon 
Hole” of the Lamoille river, that Mr. Carter mentions. 
The sturgeon come up there at a certain time in large num- 
bers and continue spawning there for twenty-four to forty-eight 
hours; and if you can get them right there in the sturgeon hole 
while they are spawning you can get males and females that are 
both ripe, and if vou can do that you can impregnate the eggs 
and hatch them. 
Mr. Titcomb: Do you mean they come every year the same 
day? 
Mr. Stone: Pretty nearly. It depends upon the tempera- 
ture of the water—it must be at least 66 degrees. When the 
temperature of the water rises to 66 degrees the sturgeon will
