Deterioration of Grain. 

 Read August, 14th, 1810. 



Permit me to mention what with me, has always 

 borne some analogy to my experience, with respect to 

 animals kept long on the same farm. I mention, in our 

 1 vol. pages 214, 15. the Mandane corn, I had it, for 

 two seasons, on my table in perfection on the 4th and 

 5th, days of July. It is now a large, though at first, a 

 dwarf plant. It is just setting to ear, and not so forward 

 as e/^ier early corn. I pursued, in every particular, Mr. 

 Cooper'^ s directions, as to my seed and planting dis- 

 tant from other corn. But it turns out exactly as I pre- 

 dicted, page 215. ^' This corn will, in a course of time, 

 change its nature, and assimilate with our own. I never 

 had any seed that did not change, with all the care I 

 could take." Mr. Cooper has great luck, as well as 

 great judgment, in his more successful practice. I am 

 mortified under the truth of my prediction ; though 

 such mortifications are not new to me. This change in 

 my corn has occurred sooner than usual in such cases. 



Mr. George Bickham informs me, that he had the 

 same kind of corn fit for the table in June. He brought 

 a few grains from the southward, and planted them 

 last year. His time for change is not yet come. The 

 distance from whence the seed came (and possibly a 

 change of soil) has favoured him.
