The Little New Year

One morning Maurice heard a knock at his window. He opened the window and asked, “Who is there?”

“I am the little New Year. And I bring presents to everyone. But I am very little and I need somebody to help me. Please come out and help!

It was cold, but Maurice put on his clothes and went out. In the yard, he found a little boy smaller than himself. The little boy was pulling a large cart with gifts.

The New Year said, “Please help me to pull this cart,” and they went up and down the hill. Soon they came to an old house.

“Here lives an old man and he hasn’t any children!” said Maurice.

“He needs my help,” said the New Year. He took out of his cart warm clothes and a New Year’s dinner and said, “I am the little New Year. Ho! Ho! Here I come. Open your door and let me in.”

Old Joe was happy when he saw all the nice gifts.

Then they went to other places and left gifts behind them.

“What a wonderful cart you have,” said Maurice, “you have taken so much out, but there are many gifts in it.”

“You are right, Maurice. There is no end to love and kindness, and I will always find people to love and be kind to. There are gifts for everyone in my cart. Come with me and you will see how happy you will be all the year round.”

“A happy New year!” called someone and Maurice found himself in bed. His sister smiled at him. “Have you had a good dream?” she asked.

“Why, where is the little New Year?” said Maurice.
“Come into Mamma’s room and see what he has brought you,” answered his sister. There he found a baby brother, the gift of the New year. Now happy Maurice was then!
