and ice-floes of successive springs will cause the river 

 to deviate from the path it has used for a number of 

 years ; thus a good pool may be rendered useless,

 suit the requirements of fish. 



Loose stones or boulders resting upon gravel have 

 as insecure foundation as the house that is built upon 

 sand ; thus pools become bare wastes, robbed of charms 

 which, if they could remain, would ofter infallible induce- 

 ments for fish. 



Fish hurry through these stretches, and seek more 

 congenial quarters where they can find shelters against 

 the stream. 



Notwithstanding the small accommodation for rest 

 extended by these gravelly pools, exhausted nature 

 compels the fish to take an easy now and again, to recruit
