during the feafon of the Vine’s bleeding. But the fuperfluous’ 
wood may fafely be taken from any part, at the time of the 
Vine’s flowering, as they do not bleed at that feafon. 
I have already obferved, that the befl feafon for pruning 
Vines is at the time of the leaves falling ; becaufe when the 
pruning is deferred till the fpring, the Vines are liable to bleed 
on the rifing of the fap, and efpecially at large incifions, where 
flrong wood has been cut away ; but when Vines are pruned 
in the autumn, there will be time during the winter for the 
wounded parts to heal, and for the pores to clofe, before the 
riling of the fap in the fpring. As Vines are fometimes greatly 
injured by their bleeding, it may not be deemed improper here 
to fay a few words on that fubjedl.

Vines, pruned even in the winter months, will fometimes 
bleed a little, on the rifing of the fap in the fpring j but if a 
Vine gets wounded at that feafon, it will, like the birch, bleed 
copioufly from the wounded part. “ It is adonifhing,” fays 
Mr. Evelyn, “ that fome trees fhould, in a few hours, weep 
more than they will weigh.” 
The difcharge from the wounded part is, in a great meafure,
