156 Thirty-ninth Annual Meeting 



Finding pitcher-mouth or hpped jars also unsuitable for 

 hatching, I bored in the McDonald jar, near the top and just 

 below the shoulder, a smooth, round hole, and inserted a six- 

 inch length of 7/16-inch rubber jar-tubing, tight fitting, a 

 little more than flush with the inner surface of the jar, and 

 when the fry emerged they passed into the fry tank through 

 this tube rather than through the ordinary glass and rubber 

 tubing from the top of the jar. This connecting tube was in 

 horizontal position, the outer end inserted into the side of the 

 fry tank by means of a %-inch bit hole, a water tight joint 

 being effected by the union of tubing and wood. Before 

 hatching commenced the end of the tubing at the tank was 

 closed with a bottle stopper of cork, whereby the jar was 

 kept full and overflowing at the customary discharge point at 

 the top, that being an open hole in consequence of the dis- 

 carding of the rubber and glass tube heretofore employed as 

 the exit for dead eggs and fry. When the eggs were ready to 

 hatch the cork stopper was withdrawn, affecting the dis- 

 charge of the jar through the horizontal rubber tube, water 

 no longer passing out at the top of the jar, and the level of 

 water in the jar dropping from the top down to the level of 

 the horizontal rubber exit. The head of water was so regu- 

 lated in the fry tank that the horizontal communicating tube 

 was at all times submerged, whereby it was impossible for 

 the fry to receive any shock or injury of any kind. The 

 hatching result was all that could be desired. 



It was long ago found that metal screens were totally in- 

 admissible in tanks for striped bass fry, and recourse is had 

 to fabric screens, cheese cloth or batiste made into carefully 

 sewed bags which are drawn over the strainer or siphon 

 cages and firmly tied. But these, until this year, were a part 

 of the siphon employed to carry away the water from the fry 

 tank. I have since discarded the siphon feature, as it was 

 (|uite impossible, in large work, to employ this without de- 

 stroying fry. The substitute consists of the same cage and 

 bag and the same kind of •'>4-inch stiff rubber hose, but dif- 

 ferently arranged. A piece of the hose about a foot long is
