follows in tlie mournful train. Then the lumberman hlls the 

 little brook with logs, the spring freshets come with the 

 melting of the snow and the warm rains, and the spawning- 

 beds of the doomed trout are rijjped up and ploughed out, 

 and the j ewelled trout disappears forever. True , if the water 

 is pure, the stream may be restocked from year to year 

 with yearling trout, but never again will they breed natu- 

 rally, owing to the altered conditions and the lack of 

 food for the young at the heads of the brooks or breeding- 

 places. 



As I said before, the question of lish-food, and more 

 especially of the food for the newly-hatched fishes, is the 

 most vital one to be considered in the re-stocking of 

 waters. It is the food of the very young fishes — the 

 microscopic crustaceans — that is the first to succumb to 

 the pernicious effects of polluted waters, and it is to this 

 cause more than to over-lishing, or seining, or dynamite, 

 that we must impute the disappearance of the hshes from 

 our streams. 



It is important, then, that the fullest protection should 

 be given the iishes by a proper protection of the waters in 

 which they live. To do this every dam should have a lisli- 

 way, in order that migratory fishes can pass up the streams. 

 This would insure the right of way to their spawning- 

 grounds. Then, strict laws should be enacted by the legis- 

 lative bodies of every State in the Union to prevent the 

 offal and refuse of manufacturing establishments from 

 being discharged into the streams. 



No man, or company of men, have the moral or legal right 

 to pollute or poison the waters of any flowing stream, there- 

 by rendering the water unflt for the stock of the farmer or 

 for domestic uses, and poisonous to the Iishes or their food. 

 If it were a fact, and could be proved, that the smoke or 

 gases from the chimneys of factories when blown over the 

 tields and habitations of men were poisonous to animals
