Every day the postman comes with mail in his mail bag.
He takes mail out of the mail bag and puts it in the letter box.
He rings the bell and then goes on to the next house.
When Bobby and Betty are at the front door, the postman hands them their mail.
When it is in the letter box, Mother lets them take the key.
They unlock the box and take out the mail.
Then one of them locks the box and the other one takes the mail in to Mother.
One day Bobby asked, “Where does the postman get the mail?”
“At the post office,” said Mother. “The postmaster has men to sort the mail and take it to the people.”
“Does the postmaster pay our postman?” asked Bobby.
“No, dear,” answered Mother. “Uncle Sam pays our postman.”
“Does Uncle Sam pay the postmaster?” asked Bobby.
“Yes, Bobby,” answered Mother. “Uncle Sam pays all the men who take care of the mail.”
“Where does Uncle Sam get his money?” asked Bobby.
“This is one way he gets money for the work,” answered Mother. “Uncle Sam sells postage stamps. Every time we buy a stamp we help Uncle Sam pay for carrying the mail.”
“I didn’t know that before,” said Betty.
“I didn’t know it,” said Bobby.
“Some day I’ll buy a postage stamp. I’ll send a letter and help Uncle Sam. I’ll help him pay his men who take care of the mail.”
