GRAYLING OVA. 103 



fifteen and twenty thousand, and though 

 several of these have died, the remainder 

 promise to do well ; they are much more 

 delicate than trout ova, both in appearance 

 and hatching, and seem to die at the least 

 provocation ; they are beautifully transparent, 

 and when viewed in the sun of a lovely 

 opalescent hue. He has discovered about 

 these a most interesting and I believe a 

 novel fact. The body of the fish is perfectly 

 visible in nine days, and the fish will actually 

 hatch out of the egg in fourteen days. 



I have some young grayling now at " The 

 Field " office, and most beautiful little things 

 they are. If they get into the boxes with 

 the trout and salmon, these fish will attack 

 and devour them.
