OF ROTATION OF CROPS. 315 



near a great town, might riot be worth L 5 in a remote part 

 of the country .f 4 On the means of improvement by extra 

 manure, as lime, marie, sea-ware, town-dung, &c. The 

 celebrated Dunbar rotation, of, 1. Turnips; 2. Wheat; 3. 

 Clover ; and, 4-. Wheat, could not be possibly carried on, 

 without the command of sea-ware, which that neighbour- 

 hood possesses : and, 5. The rotation must also depend on 

 the state or condition of the soil, whether it be old cultivated 

 land, or a new improvement ; whether it be land which has 

 been cropped judiciously, or by exhausting management ; 

 whether it is in good heart, or the reverse; whether it is 

 foul or clean. No regular system of rotation can be adopt- 

 ed, until the land is regularly drained and cleaned, and put 

 into good condition. 



The maxims which have been recommended, as the best 

 calculated to lay the foundations of judicious systems of ro- 

 tation, shall now be stated. 



1. A farmer could not well carry on his business, unless he 

 had various kinds of crops upon his farm. For instance, 

 had he nothing but wheat and beans, he might not be able 

 to procure hay and oats for his horses, and so on. By ha- 

 ving various articles also, he does not run so much risk, 

 either in regard to the season, or to the sale of the produce 

 afterwards. If a farmer entirely depended upon the cul- 

 ture of two articles, he might often be materially injured by 



f That able reporter, Mr Kerr, in his account of the Berwickshire 

 husbandry, remarks, that unless near large towns, where potatoes are 

 substituted for fallow or turnips, they r.ever constitute a complete p^rt of 

 any rotation, because unsaleable, unless at prices inferior to the expence 

 of their cultivation, and if universal, or even but a little more extended, 

 they would be unsaleable almost at any price. Berwickshire Report, p.
