TROUT 



pletely out of the egg. Occasionally, however, 

 trout hatch out head first, and in these cases the 

 young fish generally dies before it can set itself 

 free from the coverings of the ovum. Buckland 

 observed that the alevins of the char very fre- 

 quently hatch out head first, and consequently 

 that many of them die before they can work 

 themselves free from the eggs. If it were pos- 

 sible to have some one constantly watching the 

 ova at the time that they are hatching out, it 

 would be possible to save a very large proportion 

 of them, as they may be very effectually helped 

 out of the egg with a feather or soft camel's-hair 

 brush ; but this is, of course, quite impracticable, 

 unless there is some one constantly watching the 

 ova, as the delay of even a few minutes will mean 

 the death of the fish. This peculiarity in the 

 hatching out of the char has also been observed 

 by Mr. J. J. Armistead, and I have been able to 

 verify it personally. 



The mortality which occurs in the actual 

 hatching out of the alevins does not, however, 

 by any means end the trouble which the fish 

 culturist has to encounter in the rearing of char. 

 They require much more persuasion and care 

 when they begin to feed and throughout the
