In Aiiguft, I cut off the bark for an inch 

 round, of a young thriving Oak-branch, on 

 the North-Weft fide of the tree. The leaves 

 of this and another branch, which had the 

 bark cut at the fame time, fell early, viz. 

 about the latter end of OBober, when the 

 leaves of all the other branches of the fame 

 tree, except thofc at the very top of the 

 tree, continued on all the winter. 



This is a further proof, that lefs fap goes 

 to branches which have the bark cut off, 



than to others. 



The 19th of April following, the buds of 

 this branch were 5 or 7 day's forwarder than 

 thofc of other branches of the fame tree; 

 the region of which may probably be, be- 

 caufe lefs frelh crude fap coming to this 

 branch than the others, and the perfpirati- 

 ons in all branches being cateris paribus 

 nearly equal , the lefler quantity of fap in 

 this branch muft fooner be infpuTated into 

 a glutinous fubftance, fit for new produc- 

 tions, than the fap of other branches, that 



abounded
