held up over the dish and stroked with the hand slowly 

 downwards, the spawn runs out of itself. When the spawn 

 is all out, take a milter that is ready at hand in a tub and 

 proceed in the same way with him. With the milter one 

 may give a severer pressure, for the milt does not run very 

 readily from a pike. 



When one has got enough milt he takes a feather and 

 very gently stirs the spawn a few minutes, lets it stand a 

 few minutes and then washes the eggs off, turns them with 

 a little water into the plate, stirs them slowly about with 

 the feather and then carefully pours the water off. This 

 is repeated eight or ten times and then the eggs are turned 

 into the hatching boxes standing ready: the best hatching 

 boxes are of wood with wire-cloth inner apparatus. The 

 water should fall into the box at one end with a drop of 

 about a foot, in such a way that the eggs shall not be dis- 

 turbed by the jet of water. At the other end of the box, 

 the water runs off through some holes bored in the box, 

 which must, however, be so located as to keep the eggs li/o- 

 inch under water. After putting them into the boxes the 

 eggs must be spread out evenly in the wire basket (or inner 

 box) with a feather. One who has not fall enough to use 

 hatching jars, must pick them after four or five days; for 

 the bad eggs must be removed, else the good eggs will be 

 infected by the bad ones and the whole thing become a 

 mass of fungus. The picking can be done with a pair of 

 long wooden pliers which one can make for himself. 



It is certainly easier if one can use hatching jars, which 

 can be bought of Koysi in Munich. If the eggs are to be 

 hatched in jars, fit a faucet to a trough or long box. To 

 the faucet attach a rubber hose of a length corresponding 

 to the available fall. The other end of the hose is to be 

 drawn on to a glass tube 40 or 50 centimeters (15 or 20 

 inches) long, taking care that the inner diameter of the hose 

 is greater than that of the tube : the glass tube is pushed 

 through a board with a hole of a size to secure a close fit. 

 The board is laid across the jar. Let the water run till
