 very soft in tlie natural stream. 1 noticed in the month of 

 March. California ti-out spawning- in the stream. 



President: Tlie pa])er has two points. 1st, that the raiuhow 

 ti'out were l)e<iinn!n_o- to s])awi) in (he fall in France, and the 

 otlu'i'. that they were having- a vai-iety of white trout. Have 

 you had any such experience of (he formation of varieties? 



]\lr. Carter: Isn't it true that the rainhow trout of Wylhe- 

 ville spawn in the falL 



Mr. Clark: Deeemher. 



Mr. Eoot: Deeemher and January. 



Mr. Clark: They commence in Decemljer. 



Mr. Carter: Naturally they spawn on the Pacific coast in 

 the spring. 



Mr. Fullerton: Mr. President, we in Minnesota raise rain- 

 bow trout. We have never found that they varied in their 

 spawning at all. We tried an experiment four years ago; it was 

 very funny to me; I never thought very much about it. Every 

 fish culturist knows he will find very dark and very light fish in 

 the same lot of fish. The superintendent at the St. Paul hatch- 

 ery conceived the idea that he would take the male and female 

 light and keep them separately, and the dark and keep them 

 separately, and he has produced ti'out of very dark and very light 

 color, and it occurred to me tliat if lie would keep on with the 

 experiment, separating the light and dark, he would get all light 

 and all dark specimens. We have them at St. Paul swimming in 

 the ])ond. through this experiment, taking the male and female 

 of very light colors and mating them. 



President: That is what one would expect. 



Mr. l\ilIerton : We have a lot of those trout, and we raised 

 them and sent a lot down to the Jamestown exposition this year. 

 The funny thing about that is, taking a black female and black 

 male, wi! have never been able to secure a single white one.
