Mr. Carter: I should like to ask Mr. Clark al)ont that tube. 

 Is that the one with the three little feet at the Ijottoui ? 



(Mr. Clark exhibits tulie with the three feet at the bottom.) 



Mr. Carter: I have used this at Swanton, Vermont, this 

 same tul)e with these three little feet at the bottom (speaking of 

 pike perch work). T always found that these feet checked the 

 current of water, and the eggs are very apt to settle in the jar 

 and not have very good movement. Have you ever had that 

 trouble? 



Mr. Clark: Caused on account of the feet? 



Mr. Carter: Yes. 



Mr. Clark: Xo sir, never heard of it. 



Mr. Carter: Have you Mr. Downing? 



Mr. Downing: My tube sits in a jar and a rul)l)er tidx^ goes 

 down into it a sufficient distance, and the rul)l)er tuljo is small 

 enough so that there is a small circulation of air. And the busi- 

 ness of the fish culturist is to move that tube a little, so that if 

 any thing should catch on the teeth, it is iil)erated. 



Mr. Carter: The reason I ask is, that in our jars at Swan- 

 ton, we had those same tubes, Avith pike perch eggs. We had a 

 great deal of trouble with the tube checking the flow of water, 

 and the movement of the eggs in the jar. I had a new tube 

 made, by taking off the little legs of the old ones and soldering 

 a funnel on the opposite end. The tube was then self-centering ; 

 if the top of the jar was perfectly true, these tubes Avould cen- 

 ter — we had no trouble at all — just dropped them in place and 

 the funnel would center in the top of the jar. ^\e used the 

 McDonald jar, and we had no troul)le. By driving a tapering 

 piece of wood into the lower end of the tul;)e. the latter was 

 flared, giving the bottom tTd)e a slightly l)ell shape and we had 

 a very much better flow of water. This tul>e was always in the 

 center ; while I found with the others that the tube was not al- 

 ways in the center, that it sometimes hnng one way and some- 

 times another. The only trouljle with the funnel was we could 

 not get the siphon down into the jar very easily — would have to
