Analysis of School bell

Nine-o'clock Bell!
Nine-o'clock Bell!
All the small children and big ones as well,
Pulling their stockings up, snatching their hats,
Cheeking and grumbling and giving back-chats,
Laughing and quarreling, dropping their things,
These at a snail's pace and those upon wings,
Lagging behind a bit, running ahead,
Waiting at corners for lights to turn red,
Some of them scurrying,
Others not worrying,
Carelessly trudging or anxiously hurrying,
All through the streets they are coming pell-mell
At the Nine-o'clock
Nine-o'clock
Nine-o'clock
