 at prefent imagine to be obtainable. I mean to 

 profecute thefe experiments next feafon, if I am 

 not prevented by fome unforefeen accident, and 

 fhall not fail to communicate the refult to the pub- 

 lick in due time. But though my intention is to

 impofiible that a matter of fo much importance can 

 be too fully inveftigated.

 total produce per acre y is much greater than can

 derful, when he remarks, that the fize of the feeds 

 planted has never in any inftance been fufficiently
