The grass of the T. pratense, therefore, exceeds in value 
that of the T. repens , by a proportion, as 8 to 10 ; but it is 
of equal proportional value with the brown variety.

matter - - - - 2.2 dr. 
LII. Brunias orientalis (a newly introduced plant)

The proportional value of these two last, and of the 
T, pratense, and the brown-leaved variety of T. repens , are 
equal : they exceed the T. repens as 8 to 10. 
The comparative produce of these four last-mentioned 
species, per acre, has not been ascertained.

The root of this species of clover is biennial ; it pene- 
trates to a great depth in the ground, and is in consequence 
little affected by the extremes of wet or dry weather. It 
requires good shelter, and a deep soil. The produce, 
when compared to that of others that are allied to it in 
habit, and place of growth, proves greatly superior. The 
following particulars, some of which refer to results stated 
in the next two pages, will make this manifest.
