you can either let the fry develop in the box, and then go 

 free in the water you desire to stock, or you can carry the 

 fertilised spawn to some place, perhaps a hundred miles 

 away, and then place it in a similar box in the water you 

 desire to stock. In a week or ten days' time the fry will 

 hatch out in countless numbers, and must then be liberated 

 and allowed to begin their fight for life alone. In the 

 Swedish exhibit in the present Exhibition, you will see 

 some models of Lund's box. Here is one which the Swedish 

 Commissioner has very kindly lent me to show you to-day. 

 These models were exhibited in the Berlin International 

 Fisheries Exhibition, and are thus referred to, in the 

 German Official Report on that Exhibition, by Dr. Haack, 

 director of the great fish breeding establishment at 

 Huningen. In dealing with the Swedish exhibit he

 carry on the propagation of our summer-spawning fish to 

 any extent." He then describes the manner in which the 

 box is used, and refers to its advantages as follows : " As 

 will be evident to every one, the eggs which have been 

 deposited and impregnated in the box develop in a perfectly 

 natural manner . . . air, light, and sun are able to exert their 

 influences on the eggs in exactly the same way as if they 

 had been deposited on water-plants in the open water in 

 the ordinary way. Wind and waves can in like manner exert 

 their beneficial influence on the eggs, which at the same 

 time are protected from the violence of the storm, from 

 which cause alone millions of eggs are frequently destroyed 

 in the open water. The sides of the box and the branches
