HOW THE SEEDS BEHAVE eS 
under glass near the beans, in position as shown in Fig. 
27. From day to day observe the growth in each case.

The oak seedling. The A Z 
young oak plant comes out <= 4 
of the acorn in a curious way. 
It is easy to get the acorns 
to see how they behave. — 
Visit an oak tree in late 
October several weeks after 
the acorns have been falling 

from the tree. If the tree is 
situated by the roadside, or .  *%%-* ater stage of Mig: 
in a field where there 1s some loose earth which is damp 
and shaded, many of the acorns will be partially buried 
in the soil. Or you may collect the acorns and half 
bury them in a cool, damp soil, which should be 
watered from time to time. 
The root is the first to appear, and it comes out of 
the small end of the acorn, splitting the short point on 
the end of the seed in a star-shaped fashion. The root 
immediately turns downward, so that if the acorn is 
not buried the root will soon reach the soil. This can 
be seen in Fig. 28.
