Titcomb. — Some Fish-Cultural Notes 211 



Jersey, we can do very much more intelligent work and save a great 

 many fish now wasted. People are spawning and raising fish many of 

 which are thrown away when distributed. 



President Avery: Mr. Hayford is certainly taking advanced ground 

 in this matter. The information which he gives us is very welcome. 



Mr. Hayford: I wish to state further that a great deal of the 

 credit for this work is due to Dr. Embody and Professor Foster. 



Mr. Dwight Lydell, Comstock Park, Mich.: Reference has been 

 made to the bullhead. I may say that we have been propagating bull- 

 heads for a couple of seasons and it is our observation that they spawn 

 in practically the same temperature of water stated by Mr. Titcomb. 

 Their nests are about the same as those mentioned, and the bottom is 

 very rough. They spawn under the stumps, of which there are a 

 number.
