The action taken by salmon in the prepara- 

 tion of spawning-beds, and the care of their 

 young is remarkable; after passing from the 

 sea the female deposits her eggs in shallow 

 furrows in the gravel, to which they adhere by 

 a thin coating of glutinous matter. The 

 trenches in the sand are made by the female 

 throwing herself at intervals of a few minutes 

 upon her side, and while in that position, by a 

 rapid action of her tail, she digs a receptacle 

 for her eggs a portion of which she deposits, 

 and turning on her side she covers them over 

 with sand. The male seems to take no part in 

 this work, but after it is completed he acts as 

 a sentry over the eggs, for which he has at 

 times to fight fiercely, for other male fish are 

 anxious to appropriate his charge. He is thus 

 kept incessantly on the alert until the eggs are 

 hatched, and the fry able to take care of them-
