lo8 Modern Fishculture in Fresh and Salt Water. 



to destroy straight lines, and no natural stream ever 

 ran straight ; even if water is fond of making a short- 

 cut, it is still fonder of following the line of least re- 

 sistance, and will dig out soft banks and make curves. 

 If the baliks are equally soft in a straight ditch where 

 there is a good flow, the water will dig in at one side, 

 rebound to the other, and so go back and forth until, if 

 let alone, the stream will crook. See any natural 

 stream coming down a level meadow — it is crooked. 



A trout does not love a sweeping, continuous cur- 

 rent in a straight stream, but prefers pools, shallows, 

 rapids, and all the variations which occur in natural 

 streams, where it can exercise in the rapids or rest as 

 it chooses. The more difficult it is made to reach the 

 banks, through vines and alders, and the harder it is 

 made to cast the fly or to wade the stream, the better 

 the fishing will be to experts, and the more the angler 

 will enjoy the hard-earned trout he gets from it. 



Moderately still places for spawning should be pro- 

 vided, and if there is no gravel in the stream, dump in 

 several wagon loads at different shallow places, fcir if 

 there is no gravel in your stream the trout will leave it 

 in spawning time and seek gravel elsewhere, and your 

 stream will be barren. 



If it is a brawling mountain brook little can be done 

 unless to deepen pools and make places where there 

 will be eddies in times of freshets, so that the trout will 

 not be washed out of their homes. Their tendency is 

 to run up stream at such times, and they will do it if 

 they can. 



The following, translated for "The Literary Digest,"
