74 PRACTICAL TROUT CULTURE. 



By the new way every egg is saved. 



6th. By the old method every fish is driven out 

 of the race when the eggs are taken. Some of 

 them will not return, but will seek a spawning 

 place in the pond, and many eggs will be unavoid- 

 ably lost. 



By the new way the fish are not driven from the 

 race. And as the boxes are always covered dur- 

 ing the season, the fish will not even be disturbed. 

 In fact, they may spawn while the eggs are 'being 

 taken, and yet not a single egg be lost. 



This race has been tested with the greatest care, 

 and the results have been favorable in every case. 

 In many establishments where the Ainsworth race 

 had been used, it has been superseded by the 

 Collins, and tales marvelous even to the piscicul- 

 turist, whose ears are well accustomed to "fish 

 stories," have been told of its merits. By it the 

 greatest difficulties of fish culture are met and con- 

 quered, though many still remain to be contended 

 against. Yet, with us, we still hold to artificial 

 impregnation, believing that by it we can obtain 

 the best results. By long (and sometimes sad) ex- 

 perience we have gained a delicacy of touch and 

 facility of manipulation which, with us, needs 

 nothing more to be desired. During the first sea- 

 son we have hatched from eggs impregnated by 

 hand over ninety-five per cent, of the spawn taken,
