In poor land, in Pennsylvania, clover is generally 

 ploughed in when in full bloom, the second Summer^ 

 as preparatory to a crop of wheat or Winter barley, 

 by which a very large portion of vegetable manure 

 Is added to the soil, and its strength kept up ; but 

 when the land has been enriched by a repetition of 

 this process, and it is wished to lay down the field to 

 grass, the clover is permitted to remain, and annu- 

 ally top-dressed by compost; gypsum is sown the se- 

 cond year of the clover, and occasionally afterwards 

 in the proportion of one, or one and a half bushels to 

 the acre. 



Some late experiments induce a belief, that, the 

 use of gypsum in October has a better effect on the 

 grass, causing it to grow more rapidly, and to sprout 

 more early, in the following year, than when sown 

 in the Spring, according to the common prac- 

 tice. 



Two varieties of clover are cultivated in the U. 

 States, one of which grows to a much greater height 

 than the other, and is more early by three weeks ; 

 thus affording a succession of green food either for 

 soiling or pasture.
