Branch be not fo fmall as to deprive the oppo- 
fite Branch but of little of its Nourifiimcnr. 
2. I have (everal times fcen inftances of this 
in a large Catharine Pear Tree in my Garden, 
which having on feveral of its Arms a young 
thriving Shoot, grown to about two Inches 
Diameter, this Shoot attraded Nouriflimenc 
fo vigoroufly, as not only to deprive of due 
Nourifliment and kill the diredly ftraic Branch 
above it, but alfo the lateral Branches within 
eighteen Inches below it, whether on the fame 
or on the oppofite Side. 
5. And I fufped, that the blafling of here 
and there a Branch of a Tree, may fomecimes 
be owing to the fame Caufe, the depriv- 
ing them of Nourifliment by the too ftrong 
Attradion of the other Boughs. This may 
fometimes alfo be owing to a Defed in the 
particular Root which leads more diredly to a 
dead Branch, as well as fometimes to blafling 
Qualities in the outward Air, which may be 
often fufficient to kill Branches that are weak- 
ened by thefe or other internal Caufes, and 
yet at the fame time not be able to hurt the 
more vigorous Branches of the fame Tree, 
4. And that fome Degree of Defed in 
Nourifliment greatly fubjeds Fruit Trees to 
S 4 blafling^
