he managed to survive. As a boy, he causedmuch trouble for his parents. He use

d to play jokes on all of his friends and neighbors. He didn't like to go to sc

hool, and he constantly ran away from home. He always went in the direction of

the nearby Mississippi. He was nearly drowned nine times. After his father's d
