wasted, can soon he annihilated. Their reproductive power can 

 only maintain a certain equilibrium ; incline that towards destruc- 

 tion, and the entire class will quickly disappear. Treat them like 

 wild animals, and they will inevitably be exterminated ; domesti- 

 cate them, as it were, encourage their growth by putting them 

 under healthful influences, protect them from unseasonable dis- 

 turbance, let them breed in peace, guard the young from injury, 

 assist them by artificial aid, select the best varieties for appropri- 

 ate waters, and we will soon augment the supply as greatly as 

 we do with either land animals or vegetables. 



[It may be added here, that an appropriation of §15,000 was 

 made by Congress ; and notwithstanding the late date at which it 

 became available, in the few months which have elapsed since, 

 large numbers of shad have been introduced into the Allegheny 

 river; into the White river in Indiana; into the upper Mississippi 

 at St. Paul, and into the Platte at Denver, Colorado. Arrange- 

 ments have also been made for securing salmon eggs on a large 

 scale, some from the Penobscot in our own State, some from the 

 Sacramento, California, some from the Rhine, etc. These are in- 

 tended for introduction into New England waters, the Hudson, 

 the Delaware, the Susquehanna, the Potomac, and into the great 

 lakes. Nov. 72.]
