SECTION V. 



ADHESIVE EGGS. 



With eggs which are free the fishculturist has plain 

 sailing, but his trouble begins when he tackles the 

 adhesive ones, for after all his care in separating them 

 he never knows when he may not find them "all balled 

 up" and the inner ones dying. Ten years ago it was 

 thought to-be good work to hatch 30 per cent, of ad- 

 hesive eggs, but they do better now. ' 



There seem to be two classes of adhesive eggs, as I 

 have observed them under the microscope. To my 

 astonishment, I read Mr. J. J. Strahahan's article on 

 the use of the microscope in the Report of the Ameri- 

 can Fisheries Society for 1898. I have not room to 

 quote it, nor the discussion following it. Mr. Strana- 

 han advocated the use of the instrument, and the fact 

 was developed that few hatcheries, State or Govern- 

 ment, possessed this necessary instrument of the fish- 

 culturist. How a fishculturist gets along without one 

 of low power high powers are of rto use to him I 

 don't know. At Cold Spring Harbor every one of 

 my men could adjust and use a low-pressure micro- 

 scope. The instrument was my private property, and 

 I don't know if there is one there now or not. 



This may seem to be a digression, but it is not.
