 it may be necessary to protect the plants Avith vine

Rotation of Crops. — There are a few vegetables that 

 are produced in perfection upon the same soil year 

 after year, but they are exceptions to the general rute. 

 The onion tril^e is an instance of this. Most plants, 

 how^ever, require a change of soil to prevent their de- 

 generating and becoming liable to the attack of insects 

 and various diseases. ^'When one particular element 

 of aveo^etable is removed from the soil, the ve2:etable 

 cannot again be raised there, nntil that element be re- 

 stored. It is, therefore, advisable to alternate the crops, 

 by wdiich means the land will have an opportiuiity to 

 regain its original strength and fertilit}^ If old pastures* 

 were to be attentively observed, it would be found 

 that the grasses giadupJly change from season to. sea- 

 son; and in w^oodiand, it would be discovered, that an 

 entirely different kind of tree takes the place of such 

 as have decayed, or have been cut down." 



Yegetables, therefore, of the same species should 

 not follow each other, but return- at as distant inter- 

 vals as the case wdll allows "Tuberous or tap roots 

 should be succeeded b}^ those of a fibrous character; 

 perennials by annuals, and plants of a dry, solid text- 

 ure, or those left for seed, by such as are succulent 

 and juicy." 



, If every gardener should pursue this course, thor- 

 oughly spading and manuring his grounds, we should 

 hear less of varieties degenerating.
