Coral grows like a tree in the sea, and at first its color is green.
When it reaches the air it becomes hard and red. It is half a foot in
length. He who carries it will never be afraid of lightning or tempest.
The field in which it is placed will be very fertile, and rendered safe
from hail or any other kind of storm. It drives away evil spirits, and
gives a good beginning to all undertakings and brings them to a
good end.
