184 Thirty-fourth Annual Meeting. 
Dr. Evermann: Was any examination made of the stomach 
contents of the big fish? 
Mr. Clark: That is being done now, to see whether they 
have young bass in them. For fear you might think that some 
of these larger fish were small yearlings, I have brought along 
another specimen which is a small yearling, to show the dif- 
ference. 
(Specimen exhibited. ) 
Mr. Lydell: There is one part of your paper where you 
speak of your fish spawning in deep water, that is very interest- 
ing. I had some fish spawn in four feet of water, and the old 
bass stayed there and took care of those fry. They were scat- 
tered along the shore, a distance of probably thirty or forty 
feet, and the old bass patrolled his beat with great rezularity. 
Although at Mill Creek we took a screen and put it over our 
nests, over half of those were still watched by the old fish swim- 
ming around outside of the screen. 
Mr. Clark: Don’t misunderstand what I say here. I do not 
mean that the male bass does not guard them, for he certainly 
does, but not until they are an inch long. 
Mr. Lydell: I never saw him do that except where I made 
my earlier observations, there J have seen them guarding young 
bass when they were an inch and a quarter long. They would 
be scattered a long distance up the shore, but you could see the 
old bass would swim the length of the school and back and 
forth; so it was very positive that he was guarding that lot of 
fish. But I have not seen that in our ponds. In the absence of 
enemies probably he thinks it is not necessary. 
Dr. Greene: Mr. North and I have been talking about this 
matter to-day. The superintendent of our farm at London has 
been using the apparatus devised by Mr. Lydell. They used it 
two seasons and used it this year; and in conjunction with that 
he has gotten up a device of his own. He goes along the bank, 
puts down gravel for a bed, then he also drives a stick down 
there in which he puts in partitions with slots, that he can slide 
partitions in; and if the bass use that bed and the eggs are laid
