     My grandfather was a teacher.He was the headmaster of a school for boys between the ages of thirteen and eighteen.I know that he was a kind and gentle man at heart,because when I was young (and he was

old),he gave me presents,and seated me on his knees,and told me stories,but I believe the boys at his

school were afraid of him.

     At school,when he walked into a room full of noisy boys,there was silence at once.When he looked at a boy with a certain look in his eyes,that boy went red in the face,and looked down at his shoes.If a boy

brought him poor,careless work,which was not the best that boy could do,my grandfather picked up the

boy's book and threw it across the room,shouting,"Do it all again,and bring it back early in the morning!" If the boy was late,or if he forgot to birng the work,he had to do it again and again,and yet again.My

grandfather never forgot.

     He was a very different man at school from the man I saw day by day in his own home.
