PREHISTORIC MAN

PREHISTORIC MAN BEGINS TO MAKE
THINGS FOR HIMSELF.


EARLY man did not know what time meant. He kept
no records of birthdays or wedding anniversaries or the hour
of death. He had no idea of days or weeks or even years.
But in a general way he kept track of the seasons for he had
noticed that the cold winter was invariably followed by the mild
spring--that spring grew into the hot summer when fruits
ripened and the wild ears of corn were ready to be eaten and
that summer ended when sudden gusts of wind swept the leaves
from the trees and a number of animals were getting ready
for the long hibernal sleep.

But now, something unusual and rather frightening had
happened. Something was the matter with the weather. The
warm days of summer had come very late. The fruits had
not ripened. The tops of the mountains which used to be covered
with grass now lay deeply hidden underneath a heavy
burden of snow.
