Change oj' seed not necessary to prevent degeneracy ; 

 naturalization of plants ; important caution to secure per- 

 manent good quality of plants. By Joseph Cooper of 

 Gloucester county^ New Jersey. 



[The following paper on. several important agricultu- 

 ral subjects, has already been published in the United 

 States^ and in Europe; and has deservedly excited very 

 general attention. The writer is entitled to every de- 

 gree of respect, both for his practical knowledge, and 

 integrity of relation. His experience and opinions dif- 

 fer widely from those generally received. The results 

 produced, require the care and attention which few will 

 give. The merit of Mr. Cooper is therefore the great- 

 er. That both sides of a question, in which agricultu- 

 rists are highly interested, might fairly appear ; the so- 

 ciety have thought it right to add to their memoirs, this 

 important developement of the practice and success of 

 the writer. And this, not with a view to promote con- 

 troversy, but to encourage and invite candid enquu*y.]
