The merits of thi? vetchling, in point 'of pfpoduce and nutrient 

 qualities, appear, by the following comparison, to be much 

 inferior to those of the red oi: broad-leaved cultivated clover:

The red clover therefore exceeds in value that of the yellow 



• vetchling, in the proportion nearly of 7 to 3. The weight of hay 

 •'''afforded by the yellow vetchling is equal to that afforded by the 

 " red clover, which arises from the greater quantity of superfluous 

 ''moisture contained in the latter, and the greater proportion' of 

 '■ woody fibre in the produce of the former : hence one pound of 



the hay of red clover contains 40 dr. of nutritive matter, while 



an equal weight of the yellow vetchling hay contains only 17 dr. 



2 grains. 



This vetchling is not unfrequent in good pastures and in rich 

 •''meadows: it delights in moisture, and it attained to the greatest 

 ^^ perfection in a tenacious clayey soil. It is a late-springing plant, 



and the shoots come up thinly, but attain to a great length. It 

 '' appears to be eaten by oxen, cows, and sheep, but with less relish 

 ' ' than they seem to have for the Vicia sepium, (creeping vetch,) 

 «' or the red and white clovers. The nutritive matter it affords, 



• Contains a much greater proportion of insoluble and bitter ex- 

 •" tractive matters than the plants now mentioned. It affords little 



or no sugar. One hundred parts of the nutritive matter sub- 

 mitted to the action of cold and boiUng water, . and alcohol, 

 separately, afforded me —
