The seeds of this grass, when sown on a heath soil, and on a 

 clayey loam of equal space, afforded of grass, from the time they 

 were sown. May 10, till the time the produce was collected, on 

 the 20th of August following — 



Heath soil, produce of grass - - 2 oz

On comparing the properties of this grass with those of the 

 common bent {Agrostis vulgaris), it will be found inferior in the 

 proportion nearly of 5 to 3. It appears to be a very scarce grass : 

 I have only seen it twice in a wild state, and then but in very 

 small quantities. It grows on the east side of Aspley Wood, and 

 by the side of a field near Wavendon. 



From these facts and observations, the snowy-bent will appear 

 to be unfit for the purposes of the Agriculturist. It is apparently 

 too scarce a plant to be at all formidable as a weed.
