CHAPTER XI. 



DISTRIBUTION. 



HE object of this chapter is to consider 

 the tendencies of trout to work up or 

 down a stream, the motives under- 

 lying such tendencies, the seasons at which 

 they occur, and generally the policy to be 

 pursued in attempting to interfere with the 

 instincts of the fish by artificial removal from 

 one part of a stream to another. The natural 

 tendency of fish to shift their quarters is in 

 obedience to the universal law of nature, which 

 has implanted in all animals a desire to 

 preserve the individual and to perpetuate the 

 species. 



The first and most important part of this 

 work is evidently that of preserving the 

 individual, and hence it may be inferred that 

 the strongest instinct in the fish is that of self- 

 preservation. Among the conditions necessary 

 for success in this, the essential ones are, a 



Natural ten- 

 dencies of 

 trout to travel.
