DISCUSSION OF MR. THOMI'SON's I'AIF.K. 



Mr. Thompson: I might say that these zincs arc not a fair 

 sample; the reguhir zmcs are perforatetl. In connectimi with 

 the sahnon liatching l)asket and the retaining liaskct, I miglit 

 say that the llarringion tK; i\ing I'erforaliiig Co., of Chicago, can 

 make them entirely out of zinc. The price 1 hclieve is twelve 

 cents a s(|uare foot. 



Mr. llurll)ut: It would be a good deal of work lo take care 

 of a box fitted up that way. 



Mr. Thompson; Oh. I don't know, ^'ou understand. Mr. 

 Hurlbut, the use of these conijiartments is only during the sac 

 stage. We carried 65,000 in a trough twelve feet long and we 

 could ha\e raised the amount to 80.000 if we had had two more 

 boxes in use. 



yir. Hurll)ut : I was down to C'old Si)ring hatchery this 

 si)ring and I saw something there I never saw l:)efore. I saw a 

 trough full of fry. and on top of the water were a number of 

 floating boxes, also filled with fry. The superintendent told me 

 they had over six million brook trout fry in the hatchery, besides 

 some thousands of lake trout fr\'. That was all verv well for 

 them but of no use to the commercial hatcheries. 



]\lr. Thompson: T believe I heard Mr. Handy remark that 

 there was a great deal of troul)le to keep the fry from suffocat- 

 ing; this will prevent that. I might say in further explanation, 

 those that are suffocated are always imderneath, the others 

 crowding over them and shutting olT all the water, but it doesn't 

 matter how deep the}- crowd on this, the under ones are abso- 

 lutely safe. You can carry more in your trough if you use these 

 baskets, even if you don't use the bottom at all. In other v.ords, 

 you can carry more in your baskets than in your trough proper. 

 The President : You get a circulation underneath ? 

 'Sir. Thompson: Yes. 



The President: I want to ask a few (piestions about this. 

 I like this fixture for using the screen without a wooden frame 

 around it. is there any objection to that? 



Mr. Hurlbut: It is better this way than the old way. In
