SYSTEM OF CROPPING. 151

 crops be so arranged that the pea may be only once 

 in four years on the same ground ; and as often as 

 you accomplish the trenching of any interior plot, 

 lay a little lime on the surface and sow peas. They 

 will not suffer by their worst enemy, the snail;

By this attention to the system of cropping a ,

 ground at the same time will be kept in better con- /

 quently afforded, it loses something of its effect by ( 

 every repetition. By this method too you make 

 sure of a rotation of crops, having no difficulty in 

 remembering what portion of your garden has been 

 last manured, and consequently of knowing what 

 ought not to be sown or planted. The whole 

 ground should be dug with a deep rough furrow, 

 and the dung well covered in before the winter.

 have more garden ground than is requisite for the 

 supply of vegetables, it is of excellent use to lay 

 some part down in grass, to remain a few years.

 is usual in the fields, with the ordinary proportion
