3?i The Conch/ion. 



the cafe of a few bleeding trees when cut in 

 that feafon, but muft arife from fome other 

 caufe ; for by Experiment 12. and 37. where 

 mercurial gages were fixt to the ftems of frefh- 

 cut trees, thofe wounds were conftantly in a 

 ftrongly imbibing ftate, except the Vine in 

 the bleeding feafon. 



When a weak tree is pruned early in the 

 beginning of the winter, the orifices of the 

 fap-veffels are clofed up long before the fpring, 

 as is evident from many Experiments in the 

 1 ft, 2d, and 3d chapters : and confequently, 

 when in the fpring and fummer the warm 

 weather advances, the attracting force of the 

 perfpiring leaves is not then weakened by 

 many inlets from frefh wounds, but is wholly 

 exerted in drawing fap from the root. Whereas 

 on the other hand, when a luxuriant tree is 

 pruned late in the fpring, the force of its leaves 

 to attraft fap from the root will be much fpent 

 and loft at the leveral frefli-cut inlets. 



Befides, the early pruned tree being eafed 

 of feveral of its twigs or branches, has thereby 

 the advantage of ftanding through the whole 

 winter, with a head better proportioned to its 

 weak root. And fince by Exper. 16. the fap 

 is found to afcend in the winter, lefs of that 

 i han cold etude juice is drawn thro' the roots
