158 Thirty-ninth Annual Meeting 



covered that the egi^s are overflowing- fi-om that jar into tlie 

 sewer. The additional water he had turned on soon pushed 

 the accumulated air out of the tube, and too much water was 

 now being delivered. The petcock was already opened far 

 enough, the obstruction being the air in the rubber tube, 

 which he did not and could not see. It can be seen only when 

 it accumulates sufficiently to reach down into the glass tube. 

 The rubber and glass tubing devised for the McDonald jar 

 contemplated the use of two quarts of water per minute and 

 are too large in bore for the one-c|uart flow in striped bass 

 hatching. By lowering the tank head I anticipate the using 

 of more water, and, while a^'oiding the blowing out of the 

 eggs from the jar, establish such an increase in volume and 

 movement of w^ater in the tubing as to minify the accumula- 

 tions of air. 



Before concluding this paper I wish to present an innova- 

 tion in the removal of dead eggs from jars in the stri])ed bass 

 opera'tions at Weldon, N. C, which may be more widely ap- 

 plicable. It has the advantages of speed, positive identifica- 

 tion of good or bad eggs in transit, and simplification of ap- 

 paratus. I discard the conventional discharge tubing of the 

 jar, both glass and rubber, allowing the water to escape at the 

 open hole at the top of the jar. When ready to remove dead 

 eggs I take a short glass tube and place upon it one of the 

 small rubl)er washers designed for the jar stuffing-lioxes, 

 placing the washer perhaps near the middle of the tul)e. In- 

 serting an end in the jar at the waste-hole, it is hardly seated 

 when the water overflows at its top. If the tube is not 

 inserted far enough in the jar to induce the exit of dead eggs 

 I press upon its upi)er end, wlien it slides smoothly down- 

 ward through the washer until it has reached the proper 

 depth and the outward passage of dead eggs may be ob- 

 served. To make sure that these are dead eggs, note the sin- 

 gle layer that gradually spreads over the metal plate which 

 covers the top of the jar, the eggs having slipped down the 

 outer surface of the glass tube to that point, where the out- 

 side ones are in turn pushed off by the succeeding ones.
