Sixth Annual Meeting. 55 



Government last year to determine what had been the result of 

 artificial propagation of salmon in this identical stream, and 

 they gave a license to a few individuals to put out a trap-net in 

 order to ascertain the result, and in the course of the fortnight 

 there were some three hundred of these salmon taken within 

 half a mile of the outlet of this stream. This is one of them. 

 That fish, when taken from the water, was seventeen pounds in 

 weight, and I kept it as a vara avis, because I found it had two 

 marks upon it which I had put upon it in previous years. For 

 some time I pursued the custom of marking the grilse, or small 

 fish, when they came into our enclosure, after taking the milt 

 from them ; then we would take a punch and perforate the large 

 adipose fin the first year, and the second year we would put a 

 a similar hole in the tail-fin. You will see there both of these 

 holes, so that that fish must have passed through my hands, or 

 those of my assistants, for two years in succession, and this 

 would have been the third year. I claim, then, that that is a 

 fish produced in that very building where I am now rearing fish, 

 and it would have come back again this time if it had not been 

 caught in the net, making three years that that fish would have 

 migrated back to the stream in which it was bred. I brought 

 it here not only to show the result of the few years in which we 

 have been engaged in producing fish, but particularly to show 

 that the fish return to the spot where they are bred. 



It was my intention to make Prof. Baird a present of the 

 fish as a sort of record of the fish culture. I also brought it for 

 the purpose of comparing the modes of preserving specimens 

 of fish, expecting to find here similar specimens of fish stuffed 

 or preserved, and also plaster casts of fishes, which are said by 

 professional persons to be better adapted for showing the 

 description of fish than the stuffed fish itself. On that point I 

 take issue with them, and say that if properlv stuffed they will
