to the toes of that bird. The more proper English name has been derived from its being 
supposed to increase the quantity of ricii milk in cows feeding on it. It has the 
advantage of growing on the poorest soil, even on obdurate clays, where scarcely any other 
plant will vegetate. It will grow as tall as clover, and make exceedingly fine hay, though 
scarcely attaining perfection the first few years. When fully established, it produces 
annually a larger supply of fodder. It is peculiarly eligible in very poor lands ; but, 
advancing slowly after once cut, it is greatly inferior to clover. The sweetish taste of the 
leaves is said to change on the palate to a disagreeable bitter. Swine refuse it. E.)

*f* (Sir H. Davy has shown that the nutriment of Clover contains a greater proportion of 
bitter extractive and saline matter than the proper grasses; and that when pure Clover 
hay is to be mixed as fodder, it should be with summer hay rather than after-math hay.
