IN 1841 a short Treatise on Fish-ponds issued from

 the advantages which water-owners might easily de-

 and breeding of fresh-water fish, and the large amount 

 of good they might do to the community at large by 

 the great quantity of wholesome food they might biing 

 into the markets of both town and country.

 power of multiplying its own species ; but fresh waters 

 require care and protection : they must be managed 

 as well as protected, and they must be protected and 

 managed on sound principles, or all rivers and streams
