GRAFTING. 53 

Fig. 23.—Adhesion of two roots of carrot. ‘Gard. Chron.,’ 1851, p. 67. 
A not uncommon malformation in mushrooms arises 
from the confluence of their stalks (fig. 24), and when 
the union takes place by means of the pilei, it sometimes 
happens, during growth, that the one fungus is detached 
from its attachment to the ground, and is borne up 
with the other, sometimes, even, being found in an in- 
verted position on the top of its fellow." 
The garden operations of budding, grafting and 
inarching have already been alluded to as furnishing 
illustrations of adhesion, but it may be well to refer _ 
briefly to certain other interesting examples of adhesion
