       When Abraham Lincoln was just a boy, he had to help his father to look after their farm. It was hard work and there wasn't anything interesting for him. Abraham wanted to go to school, but there was no

school there. He was sad most of the time.

       Mrs. Lincoln loved the boy very much. She tried her best to make Abraham happy. One morning

she got up early and went to the town. It was a long way so it took her a long time to get there. She
