92 SALMONID.E. 



" A small space will receive a great quantity of spawn, yet 

 they must not lie too thick, otherwise when many touch each 

 other too closely, they will get in a few clays into putrefac- 

 tion, and have the appearance as if a fine downy wool was 

 spread over them ; if they remain in this state they are unfit. 

 To prevent this, take a thin slice of wood, or a paddle about 

 the breadth of a hand, and paddle with it backwards and 

 forwards on the spot where the spawn lies too thick, to spread 

 by this motion the spawn asunder. 



"3. It will be necessary to repeat this manoeuvre twice a 

 week, or at least once a week, and by paddling with your 

 wooden slice in all parts, you will bring the water upon the 

 eggs in motion ; for let the water be ever so clear, there will 

 adhere to the eggs in a few days a subtle filth, which lays the 

 foundation of their corruption, even when the young fish is 

 already alive in the egg ; therefore it is necessary to clean 

 them by this gentle means. 



" 4. After the eggs have been about three weeks in this 

 state, one may perceive through the hard skin a divided black 

 spot, which are the eyes of the young fish ; the body is too 

 transparent to be seen with the naked eye, but after four 

 weeks, if you squeeze one of the eggs between your fingers, 

 you will see the fish make a motion and turn within, then 

 you perceive his form. 



" At last, after lying five weeks in this state, and under a 

 continual current of running water, the young fishes will bore 

 their heads through the shell of the egg, and under motion 

 with their bodies will, in about half an hour, free themselves 

 entirely from the shell, with the yolk of the mother egg 

 hanging to their bellies like a small bag ; so soon as they are 

 out of the egg, they will still be in the cavities between the 

 gravel, and have then the appearance as if the head of a pin 

 was fastened to a reddish field pea, on account of these hang- 

 ing bags. For three or four weeks they receive their nou-
