eral pails full of water which when poured into the box cleared 

 up the water, they were all right, and showed no signs of dis- 

 tress. 



Mr. Lydell : You ought to have that little stream from Mill 

 Creek running into these boxes, (Laughter). 



Mr. Clark : I would like to ask if your screen was all around 

 this box, why you did not keep the screen clean, then you will 

 have your circulation of water all right. 



Mr. Beeman : I used the common wire mosquito netting for 

 a screen, and yet the little bass would go through it; it is not 

 fine enough, and the moment I cleaned up the screen some of 

 the bass would escape. 



Mr. Nevin : Cheesecloth will answer the purpose. 



Mr. Beeman: I used that on the front. An improvement 

 suggested itself to me in this manner. On the side opposite the 

 open side I would suggest someone try leaving an opening there 

 of a foot in width extending from the top to the bottom of the 

 box, or down to the gravel, and during the time that the eggs 

 are deposited and the parent fish caring for them, I would slide 

 a board in that place instead of a screen, and just before the fry 

 rise I would remove the board and put in a screen there. Also 

 the screen in front of the box. This would give a little circula- 

 tion of water through the box. 



Mr. Clark : That is a good idea, but I cannot conceive why 

 your wire around here, being put there for the purpose of giv- 

 ing you a circulation of water, .should not be kept clean. 



Mr. Beeman : That would be all right if the wire netting is 

 fine enough. Another point : this wire was placed from the sur- 

 face of water down about four inches. The rest of the way down 

 it was enclosed with boards perfectly tight. So, while the water 

 might circulate a little at the top of the box it remained some- 

 what stagnant at the bottom. 



Mr. jSTevins : Put your wire netting down within a foot of 

 the bottom. 



Mr. Beeman : The idea in constructing a box on three side? 

 is, to give the fish ample protection, and furthermore to handle 

 the fry after they rise, because the school quickly scatter and it 

 is hard to capture them. So that you have got it in a nutshell ; 

 if you have the boxes so that you can screen them in. You have
