cloth trays — I do not think it makes much difference what they 

 are moved on, whether flannel, cheese cloth or wire trays. If 

 you do not have any dead water around them and you have the 

 temperature right I do not think it makes a particle of differ- 

 ence — I would just as soon move them on a board, if that board 

 did not have anything about it that would contaminate or injure 

 the eggs. 



Mr. Titcomb: I think Mr. Hubbard's experiments are very 

 interesting; but to carry them to a conclusion, in other words, to 

 determine whether the transportation of the green eggs b}' the 

 jar method, when they are from one to twelve days old is en- 

 tirely without injur}^, we have got at the same time to eye some 

 eggs right at the collecting station, and not only eye them there, 

 but follow the results through to the young fish. I think that 

 very frequently we get trout egg6 to the e^'cd stage, they look all 

 right, and they hatch all right, and tlicn we ha\e weak fry, and 

 we do not know what the trouble is, and in many instances, I be- 

 lieve, although I have never followed a control experiment to 

 prove it, the weakness in the fr}' and the mortality among the 

 young fish are caused by a wealcness in the egg, or possibly the 

 weakness goes back to the parent fish, but will not be noticeable 

 until the fish has begun to feed. 



I just want to bring out in connection with this matter the 

 point that many of the superintendents who are making experi- 

 ments (and I place myself in the same category when T was 

 superintendent), do not carry the experiments far enough: 

 they do not have a test in comparison Avith the ordinary method. 

 I simply bring that out for consideration, and in connection 

 with your work anotlici' ycni-. ihat you carry tlie cxperimcnttj 

 still further. There is no question but that you can take the 

 green trout eggs and carry them long distances with very littl*: 

 injury. You can carry them almost any way. You can take an 

 ordinary fish can and fill it half full of oggi^ and half full oi 

 water and put it on the cars and cany it all day, if you do nor 

 get your temperature too high. They get more or less aeration 

 from the motion of the cars, and will go through all riglit and 

 ]')roduce good fry. 



Mr. James Xevin, of Madison : We always ship our eggs on 

 wire travs. We fill the top of the tray full of crushed ice. and
