70 Breeding Salmon and Trout. 



tions of temperature were very slight, with the purest water 

 passiug- through up-to-date filters, made the work quite easy, and 

 one year we hatched out ninety per cent, of the eggs. There is 

 a very easy way of counting the eggs which may be of use to you 

 if you ever have to deal with them in large numbers, for beHeve 

 me the counting of even ten thousand eg-gs one by one is a very 

 tedious business. Take a square board of any size you Hke and 

 mark it off in square inches. Place as many eggs as you can in 

 one layer on one square inch, count them, then cover the whole 

 board with a layer of eggs and multiply by the number of squai'e 

 inches. 



In conclusion, let me say that when the little fish first comes 

 out of the egg he does not look anything like the little ones which 

 you may have seen swimming about in our burns. He has a head 

 and a tail, and a very thin body, but underneath where his 

 receptacle for food ought to be, he has a large sack hanging down, 

 the contents of which are gradually absorbed and upon which he 

 lives for some six weeks. Day by day the sack becomes smaller, 

 and at last when he has arrived at his proper shape he opens his 

 mouth and begins to feed. It would weary you to enter upon all 

 questions of feeding and the care of little fishes. They may be 

 fed in the boxes for a few weeks, and then turned out into care- 

 fully prepared ponds, and the next year when they have put on 

 their silvery dress as smoults should be turned into the burn or 

 river, and with all good wishes sent off on their journey to the sea. 



Should any of you wish to take up this subject there are text 

 books touching on the matter in all its branches, and you have 

 close to you, in the manager of the Solway Fisheries, one of the 

 best exponents of the art of rearing fish that I know. I wish 3'ou 

 large families and good success in rearing them, and trust that the 

 fish will show their gratitude for all your trouble by coming back 

 from the sea well fattened and of large size and allowing you to 

 catch them in great number.
