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. 1 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 other 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 cages. 
Mr. George Bickham informs me, that he had the 
same kind of corn fit for the table in June. He brought 
afew 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.
