DISCUSSION. 
Mr. Clark: The point in his paper is good, that when the 
bass get large, weighing four, five or six pounds, they do not be- 
in to do the damage in a pond containing fry that yearlings do.

Mr. Meehan: Our experience has been that we have to get 
them in in the fall and if we put them in in the spring we can- 
not do a thing with them. 
Mr. Lydell: One lot I put in this spring, did not do any- 
thing, and the second lot I put in in the evening and the next 
afternoon they spawned. We got such good results because they 
were so near spawning that they could not help themselves. 
Mr. Meehan: It is a curious thing, because I had the experi- 
ence with the small mouth bass that if we did not get them in in 
the fall we could not get anything out of them at all. 
Mr. Clark: We had small mouth bass at Northville that 
spawned six or seven days after they were put in, wild fish 
brought from the Saginaw River. 
Mr. Nevin: In regard to building bass ponds, are you build- 
ing large or small? 
Mr. Lydell: Ponds number three, five and one are my regu- 
lar breeding ponds. The large ponds are for large mouth bass 
and for rearing. I had to take them and transfer them to num- 
ber seven, where I left them for breeding this year. 
Mr. Titcomb: How many adults did you put in number 
three ? 
A. Fifteen or eighteen pairs. I have been reducing the num- 
ber of adults to the pond ever since I began propagation, and get 
better results all the time. 
Mr. Clark: If you had just the kind of place you wanted and 
could do just as you wanted, would you have large ponds for 
rearing bass? Would you prefer half an acre, three-quarter’s 
of an acre or ten acres? 
Mr. Lydell: I do not think I would have a pond larger than 
300 by 150 feet. I think for rearing exclusively, if your pond
