fap of other branches; efpecially when fo ' 

 months after the inoculation, the ftock t 

 the inoculated Jefiamine is cut off" a n t 

 tie above the Bud; whereby the ft 0c fc 

 which was the counter acting part to the 

 ftem, being taken way, the ftem attracts 

 more vigoroufly from the Bud. 



Another argument for the circulation of 

 the fap, is, that ibme forts of grafts will 

 infect and canker the (locks they are grafted 

 on : But by Exper. 1 2 and 3 7, where mer- 

 curial gages were fixed to frefh cut fterns of 

 trees, it is evident, that thofe fterns were 

 in a flrongly imbibing flate; and conic- 

 quently the cankered flocks might very like- 

 ly draw fap from the graff, as well as the 

 graff alternately from the fleck; juftinthe 

 fame manner as leaves and branches do 

 from each other, in the vicillitudes of day 

 and night. And this imbibing power of the 

 flock is fo great, where only fome of the 

 branches of a tree are grafted, that the re- 

 maining branches of the flock will, by their 

 ftrong attraction, flarve thofe grafts j for 

 which reafon it is ufual to cut off the great- 

 eft part of the branches of the flock, leaf.
