by placing: a narrow strip across the trough upon One of 

 the two inch strips dividing the nests. Then sink the 

 pan gently to the edge in the water of the trough, at the 

 same time tipping the pan, so that the water in the trough 

 and in the pan shall come together with as little current 

 as possible. Then the edge of the pan may be sunk into 

 the water, and by tipping the paii a little more, the eggs 

 will flow out without injury. By moving the pan while 

 the eggs are running out, they may be spread uniformly 

 over the bottom. If they fall in a heap, take the bearded 

 end of a feather, and move the water with it in the direc- 

 tion you wish the eggs to go, and they will follow the 

 current thus created. This may be done without touch- 

 ing the eggs with the feather. Distribute the eggs as 

 evenly as possible over the surface of the nest. Where they 

 are placed upon wire sieves, these may be moved and 

 shaken under water so as to distribute the eggs evenly. 



The strip which was placed across the trough to raise 

 the water should then be removed. Care must be taken 

 that it be not removed so suddenly as to cause a rush of 

 water, which would carry most of the eggs away with it. 

 Raise the strip a little way from the bottom so as to let 

 ihe water run out gradually, and when it is very nearly or 

 altogether at the proper level, the strip may be removed 

 entirely. Those who have a nursery attached to the 

 troughs place the earliest eggs in the lower end of the 

 trough, and keep placing them toward the top, so that 

 the fish which are first hatched can run first into the 

 nursery without disturbing the others. We practice pla- 

 cing the eggs in the highest end of the trough first, be- 

 cause the eggs earliest placed, hatch out first, and the 

 water should be raised over them, as they i-equiie more 

 oxygen thali the egg. . If these first should be placed at 

 the lower end of the trough, in order to do this the water
