The produce at the time the seed is ripe, as above stated, was 

 taken the season preceding that in which the flowering crop was 

 submitted to experiment; and as the season of 1812, in which the 

 seed crop was ascertained, happened to be more favourable to the 

 growth of this grass than that of 1813, when the flowering crop 

 was experimented upon, and the seed crop likewise, according to 

 the following details of results, it will be more just to compare the 

 produce of the crops of the same season. 



At the time the seed is ripe, the produce of the season in which 

 the flowering crop was ascertained is
