longer than 24 hours ; two large collecting tanks were used and 

 cleared alternately of the fry every 24 hours. 



The fry were admitted to the river through a large rubber 

 tube extending below the surface of the water and connecting 

 with a large iron tub on the deck of the tug; while the tug was 

 moving slowly the fry were poured into the iron tub and they of 

 course found their way through the rublier tube into the river, 

 care being taken to keep the tub full of water and fry until the 

 last of the fry were planted. 



From a practical stand.point, it appears to me that there is 

 but little opportunity for improvement in the present method of 

 try production. But if protected propagation is to provide also 

 for the development of tlie output, there is a vast unexplored 

 field before us. 



Countless millions of fry can be called into existence by 

 assisting nature to the mere extent of allowing her to assert her- 

 self unmolested, but v,^hen the fry, stage is reached a far graver 

 question stumps the student of modern fish-culture. The iiere 

 production of the fry, should the good work end there, availetli 

 nothing; it is the maintenance of the same and the maturity of 

 the living germs that really constitute the chief aim of our work. 



Where shall the fry be placed in order that they may be 

 subsisted and made to grow •: 



Truly they can be placed on natural spawning groimds and 

 thus given an equal opportunity with nature's fry to battle for 

 existence. 



But who knows positively that spawning grounds are :he 

 true feeding areas for the newly hatched fry? In the first stages 

 of reproduction the utter lack of solicitude, or even provident 

 instinct, in the parent specimens resulting in such desolate waste 

 (in nature's haunts) of the great reproductive possibilities so gen- 

 erously endovv'ed by nature warn us and our investigation lead 

 us to conclude it more than likely that not a single trace of 

 anxiety is manifest in the parent fish for the well-being of the 

 fry. When we consider the infinitely small percentage of fertili- 

 zation in the natural state, and the lavish, reckless, extravagant
