6. To raise those crops the most likely to be produc- 

 tive of manure ; hence green crops are to be recom- 

 mended, and barley is to be avoided, producing, when 

 compared to other crops, the smallest quantity of 

 straw *. 



7. To arrange the crops so as to keep the land in good 

 condition, and increasing, rather than diminishing in 

 point of fertility f. This is best accomplished by the 

 convertible husbandry, (or white and green crops in suc- 

 cession), and giving every part of a farm the advantage 

 of being occasionally pastured. 



8. To commence a lease with a meliorating system, 

 but during the remainder of the term, to crop the land 

 in such a manner, as to reap, in moderation, the advantage 

 of the improvement that has been made. In forming a 

 rotation, therefore, those articles should be included, 

 which are the most likely to afford a profitable return to 

 the farmer. 



Keeping these maxims in view, we shall now proceed 

 to consider, the various rotations which have either been 

 adopted by, or recommended to, the attention of the far. 

 mers in Scotland. 



* A fair average of straw produced by the different crops, 

 according to Mr Brown of Markle's calculation, is, Wheat, 

 1 60 stone; Beans and pease, 130; Oats, 120$ and, Barley, 

 only 100, per Scotch acre. 



f Mr Andrew of Tillilumb justly remarks, that it ought 

 to be a leading maxim with all farmers, never to take a crop 

 but when their ground is in such situation that, if the season 

 favours, it may give us good a crop as such land will carry. 

 Hence their first care and chief study ought to be, how they 

 may bring their ground into, and keep it in the best order, 

 and not what they can draw or take ; for if they are kind and 

 generous, the grateful earth certainly w\}\ give.
