State they contain 1.17 per ct. Nitrogen, and 

 1.60 water; in the dry state, 2.89 per ct. Ni- 

 trogen. 



In some mountainous countries, the leaved 

 pine twigs are used for the same purpose. 



Meadows. Meadows require to be, from 

 time to time, cleared up, for the nature of the 

 soil sometimes prevents their indefinite preser- 

 vation in a proper state. In a field bearing 

 33,750 lbs. of grass, per 2\ acres, the crop 

 furnishes a manure equal to 1,500 lbs. Nitro- 

 gen for a like surface, and yields three crops 

 of wheat, amounting in all to 205 bushels. 



Lupine. The Lupine used in France, as a 

 green manure, is not sown until March, and 

 must be turned under as soon as it is in flowers. 

 This plant has not been analyzed; but its 

 powerful effects allow the inference that it is 

 very rich in Nitrogen. Lupine seeds, as ana- 

 lyzed by Payen, contain, in a normal state, 

 3.49 Nitrogen, in a dry state, 4.35. This, 

 then, is a rich manure. 



Beans. Bean-stalks, in flower, may be con- 

 sidered as a demi manure; they are used 

 chiefly in fertilizing lands for the growth of 

 hemp. 



Vetch, An expensive green manure.
