PERSONALITY OF PLANTS 
for next year’s growth by putting forth minia- 
ture shoots and leaves folded up in warm brown 
overcoats. At spring’s urgent call, the buds 
have merely to cast aside their coverings and 
step out into the warm sunlight. These buds 
really make a tree a community of individuals, 
because each one is capable of reproducing 
everything that has occured on the plant up to 
that point. This is the principle on which 
grafting is carried on. 
The most wonderful thing in all plant struc- 
ture is the plant cell. There are anywhere 
from six thousand to twelve thousand of these 
living units to the square inch. In their rest- 
less, moving protoplasm lies the mystery of life 
—the directing energy which controls the 
plant’s activities and makes it a conscious, in- 
telligent organism.
