started, its importance presently became obvious, so 

 that thirty years have carried to great perfection the 

 precepts which practice has afforded in this branch of 

 rural economy. This subject will demand a principal 

 attention from our young farmer, who should well 

 consider the courses to which his soil is applicable. 



General Principle. It is now well known that some 

 crops exhaust land much more than others : that 

 some, notwithstanding they exhaust, return by being 

 consumed on the farm, as much, or more, than they 

 drew from the soil in their growth : that some ad- 

 mit profitable tillage and cleaning while growing ; and 

 consequently, clean, instead of rendering the land 

 foul with weeds ; while others, not admitting such 

 tillage, and being exhausters, if combined in succes- 

 sion, will deteriorate the land and fill it with weeds. 

 Practice tells us, that by a due arrangement of these 

 crops in courses, land of almost any description may 

 be kept perpetually clean and in heart.
