324 Modern Fishculture in Fresh and Salt Water. 



be, as, like gregarious mammals and birds, they flock 

 together, following the leadership of whichever for the 

 time takes it. The idea is suggested that the senses 

 may be the guiding agent, that a fish goes nosing along 

 the coast, or tasting the streams, until it recognizes its 

 own. The convexity of the cornea must afford the 

 fishes a very limited range of vision. The supposed 

 dullness of the sense of smell and of taste in fishes 

 might alone dispose of the suggestion that these are em- 

 ployed. The following occurrence, however, would 

 seem to decide to the contrary : The Russian River, 

 emptying into the Pacific, north of San Francisco, had 

 its mouth entirely closed by the waves during the 

 storm. The colony of salmon made their yearly mi- 

 gration from the deep waters toward the mouth of the 

 river, and many of them raced through the surf and 

 landed higli and dry on the sand that walled them out 

 from their native river. The migration of the salmon 

 into some of the Pacific rivers is a frenzied advance 

 over shoals, rapids and cascades, far into thin streams 

 and brooks, where the}- arrive battered and wearv. to 

 accomplish their exhaustive reproductive labors and 

 drop back, the sport of the current, dead and dying, 

 toward the sea,"
