How to obtain it. 



until all the eggs are clean. Ova packed on layers of linen fabric 

 may on unpacking be similarly treated. Take up the cloth by the 

 four corners with the eggs upon it. Immerse in a bowl of water, 

 let one side go, and gently withdraw it, and the eggs will float off. 

 Should a few adhere to the cloth feather them off. 



Even on the grilles the moss may be washed off. I have 

 seen a lot of eggs successfully laid down with much moss among 

 them. A strong current of water being turned through the 

 hatching boxes, the moss at once floats off, and is caught on the 

 screen near the outlet of the box. The work is quite easily done 

 with a little practice, but the beginner must not expect everything 

 to go just right at first without any trouble. I have seen 

 individuals who made great bungling at the work at first soon 

 acquire an amount of dexterity, which enabled them to manipulate 

 large quantities of ova successfully. 



Trout ova may be packed and sent anywhere in Britain, or 

 on to the Continent, immediately after impregnation, provided 

 the journney does not exceed forty-eight hours, and they are 

 travelled at a low temperature. The best time of their existence 

 for such journeys, however, is when the embryos are well 

 developed, and the eggs are in the stage called " fully eyed." 

 They are then near hatching, and in a mild temperature should 

 hatch in a few days after being received. When very close to the 

 hatching point they may sometimes be sent with safety by using 

 ice, and even later in water in bottles quite successfully. The 

 latter plan is not to be recommended, but may often be safely 

 adopted in an emergency.
