 should produce such crops as it actually does. 

 When the lieart of the land is supposed to be 

 gone or greatly deteriorated, the remedy is, 

 after taking a crop of wheat from it, to allow a 

 natural layer of clover and grass, which serves 

 as summer feed for cattle ; in the autumn it 

 receives a ploughing in the usual way, and in 

 the ensuing spring is again put under wheat or 

 oats. This plan is unprofitable and injudicious, 

 the stock derives but little advantage from the 

 herbage, while with a little more care the 

 grounds might be turned to much better ac- 

 count. The introduction of different kinds of 

 grasses and other succulents, regulated by a 

 moderate degree of skill, could not fail being 

 attended with complete success; among the 

 various sorts, the English red and Dutch 

 white clover are worthy of notice, being cal- 

 culated as well for summer feed as excellent 

 winter store ; to these might be added the yel- 

 low Swedish turnip, a species perhaps superior 

 to any other of its class, as it will endure the 

 most violent frost, and maintains its goodness 

 until the springs as well as in autumn : that the 

 acquisition of such a plant to a country always 

 subject to a long winter would soon become
