3- Clover ; 4. Drilled wheat. Being extremely anxious 

 to ascertain, not only the details of this system, but also 

 whether the plan, when persevered in, continued tobe pro- 

 ductive, I procured the following particulars regarding it, 

 from Mr-Hume of East Barns, and Mr Rennie of Ox well 

 Mains, two respectable farmers, by whom it is adopted. 

 They informed me, that some deviations were occasion- 

 ally made from the plan, (but not such as to alter the 

 general system), by cultivating, on rich spots, pease, 

 or beans, or potatoes, in lieu of turnips, and by having 

 three green crops in succession, when the soil is much 

 subjected to the growth of annual weeds, or requires to 

 be refreshed. It would appear, however, that without 

 a good climate, such as they enjoy in the lower part of 

 East-Lothian, and great quantities of sea-ware, or other 

 adventitious manure, it would be impossible to conti- 

 nue such a rotation. The quantity and sorts of dung 

 usually applied, is, to the amount of about thirty double 

 horse cart-loads per Scotch acre, to the land intended 

 for turnips. The turnips are always eaten on the ground 

 by sheep, which is, (where the situation will admit of 

 it), by far the best and cheapest method. The same 

 quantity of dung or sea-weed, is also applied on the 

 grass land before ploughing. It is found, that applying 

 the sea-weed early in spring, on the clover to be cut, if 

 laid on in dry weather, answers well for the succeeding 

 crop of wheat. 



The soil where this rotation prevails, is of a dry qua- 

 lity. If such a rotation were attempted on wet soils, it 

 would be advisable to sow oats after the grass, instead of 

 wheat *, (and that is in general the preferable system), 



* Upon the trial of a small piece of grass, partly wheat, 

 and partly oats, both close together, Mr Dudgeon of Prora 

 actually had thirteen, bolls of oats, and only seven of wheat
