pends on their cellular tissue being in an en¬ 
tire and healthy state. Thus, it is quite evident 
that if the spongiole of any fibril be crushed, 
or even the cellular tissue injured, it can no 
longer act as a mouth and throat to convey 
food to the plant. When this is the case, 
the injured part should be instantly re¬ 
moved; as its elasticity can never be re¬ 
stored, and it is much better for the plant to 
be forced to throw out a new fibril, than to 
be obliged to carry on its circulation weakly 
and imperfectly with a diseased one. When¬ 
ever a plant is taken up for transplanting, its 
roots should therefore be carefully examined, 
and all their injured parts cut off, before it is 
replaced in the ground. Deciduous plants, 
and particularly trees and shrubs, are gene¬ 
rally transplanted when they are without 
their leaves; because at that season they are 
in no danger of suffering from the effects of 
evaporation. 
Shading is necessary after transplanting 
all plants that retain their leaves; as the eva¬ 
poration from the leaves, if exposed to the 
full action of the light, would be greater than 
the plant could support with a diminished
