ABOUT THE TIME.
Many years ago people did not have clocks. They told the time by the sun and the shadows of the streets. At first, they used sticks placed in the ground instead of trees. They made marks on the ground, and the shadows from the sticks told the time of day.
Later, men began to use sundials. Some sundials were boxes with a stick to cast a shadow. Men were able to carry the sundials box with them. The mark for noon was very important. The sundial always had to face the same way or the time was wrong. Sundials were good only on sunny days, not on cloudy days. They were the first kind of clock.
