Jan.~\ TRENCHING, &C. 14! 



up a part of the fubfoil in order to gain depth, it 

 is proper to fallow the land for fome months pre- 

 vious to planting. The time, therefore, for fuch 

 digging or ploughing, fuppofmg it were intended 

 to plant in February or March, is rather Novem- 

 ber than January. But we have no hefitation in 

 faying, that if the ground be broke up at this 

 time or in February, by taking a fallow crop of 

 potatoes or turnip, and planting a year hence, 

 there would, with refpeft to the growth of the 

 trees, be no time loft. If the foil be fliff, and in 

 grafs, it may be proper to take firft a crop of oats, 

 and then a fecond of potatoes, dunged, previous 

 to planting the trees. 



In cafes where the ground is to be prepared by 

 the plough alone, and where the foil is deeper 

 than one of the improved Dalkeith ploughs can 

 reach, it would be very proper to make one plough 

 follow another in the fame furrow; by which 

 means the foil may be ftirred fully a foot in 

 depth. This operation, it muft be remarked, can- 

 not, however, be fo well done in the breaking of ley 

 ground, as in flubble or open furface. If the ley 

 were reduced by a crop of oats or potatoes, the 

 land might be effectually prepared in this manner 

 in autumn and winter. In all cafes, it is obvi- 

 ous, that where the foil is only fo deep as that 

 the plough can, in this manner, command it, this 

 inuft be the cheapeft mode of preparation. The
