fible. The Walnut, although pufhing a very 

 flrong root downwards, fhould never, if poffible, 

 have the tap root fhortened ; for if it is, the up- 

 right dire&ion of the growth will be greatly pre- 

 vented, and probably the health of the plant much 

 impaired. Seedlings, not immediately planted out, 

 mud be shoughed with care. 



TRENCHING VACANT QUARTERS, 



Such quarters as have been feverely cropped 

 with trees for fome confiderable time, and are 

 now vacant, will require to be trenched. This 

 work fhould be performed with much care, not 

 to leave any fad or unmoved ground between the 

 trenches, and not to bring up much of the fub- 

 foil. It is highly improper to attempt the deep- 

 ening of the foil at once ; fubfequent trenchings 

 muft be looked forward to, for making the land 

 fufficiently deep. 



We have feveral times feen the bad effe&s of 

 too deep trenching, efpecially for raifing trees in 

 a nurfery j and ftiil more particularly for raifing 

 feedlings. Two, or at the moft three inches of 

 the fubfoil, is all that fhould be brought up in a 

 feafon, unlefs it be evidently of a fuperior or e* 

 qual quality with the furface, which is very rare- 

 ly the cafe. Even if the upper foil be ten or 

 twelve inches deep, it will be more fuitable for 



raifing
