 quantity of aqueous particles enter into 

 thofe parts of the trees where the amputa- 

 tions are made. In February there are 

 yifible proofs of the fap becoming more li- 

 quid than it was in January, by the buds 

 being increafed in bulk. This ihews that 

 the vefiels are more extended than when 

 the buds were lefs, as at the time their 

 leaves were newly flied. It is obferved by 

 many praflitioners, to cut the ftrongeft 

 trees lateft in the fpring, in order to abate 

 tiieir vigour; but it is an unprofitable cuf- 

 1pm, efpecially when the trees are young 

 and the walls covered but in part, for thea 

 trees of thofe kinds cannot be too ftrong, 

 if rightly ordered by dilbudding in fpring, 

 and properly difplaying their branches at 

 all times of nailingj then the new-made 

 branches will bloffom the next year, from 

 trees that are the moft vigorous. A great 

 difacJ vantage attends the cutting of trees too 

 late in the fpring, or when their bloffom- 

 buds are either open or near it ; for then 

 they are in danger of being difplaced more 

 than when they are lefs. Upon a ftrong 

 tree there cannot be too many buds -, for,
