Sir Humphry Davy has shewn likewise, that the plants most 

 liked by cattle have either a saline or subacid taste, as in the 

 instances of red and white clovers, and the superior grasses. 

 This plant, however, has a greater excess of the bitter extractive 

 and saline matters, in proportion to that contained in these plants, 

 when compared to the rest of the pasture grasses. It is nauseous 

 to the taste. From these facts and observations, it does not seem 

 to be a plant that possesses unequivocal merits for admission into 

 the composition of pasture. It attains to the greatest size on 

 tenacious clayey soils.
