improvement, and that those who carry into execution a 

 profitable system of management, bid fair to engage the 

 notice of the neighbourhood, in spite of the impression 

 of those habits which attach to unlettered farmers, and 

 thus may be the source of essential service, both to the 

 cause of agriculture and to their country. 



On this part of the subject it may be sufficient to add, 

 that almost the same crops, which, under one system, 

 would be extremely unprofitable to the farmer, and in- 

 jurious to his land, under another rotation, with an in- 

 tervening crop or fallow, might be not only profitable, 

 but might promote its fertility *. 



lu considering this important subject, it is proposed 

 shortly to discuss the following particulars: i. The 

 principles or maxims on which rotations ought to be ar- 

 ranged : 2. The various sorts of rotations which have 

 been adopted in Scotland, for various periods of two, 

 three, four, five, or for a longer period of years: 3. Of 

 double rotations, where two systems are in a manner 

 carried on at the same time : and, 4. Any miscellaneous 

 particulars connected with this branch of the inquiry. 



X. Of the principles on which Rotations ought to be ar~ 

 ranged. 



I have endeavoured, in the preceding section, to point 

 out the various articles which are principally cultivated 

 in Scotland. These articles must be raised, either con-

 Gowrie. i. Wheat. 2. Barley. 3. Oats. 4. Ptase and 

 beans, when the crops were trifling, with the new system, i. 

 Fallow. 2. Wheat. 3. Beans. 4. Barley. 5. Grass. 6. 

 Oats. Under the first course, the rent was only from 25 s. 

 to 30 s. per acre. Under the second, it has in many case* 

 risen to L. 5 or L.Gfer acre, and upwards.
