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 j it will be more just to compare the pro- 

 duce of the crops of the same season.
