After a while the young man came to his father and said:
"I cannot do as you wish."
His father was so angry that he turned his son out of doors. Young Penn would have had a sad time if his mother had not sent him money to keep him from want.
He began to preach in the streets of the city. He hoped other people would listen to him and also become Quakers. It was not long before he was arrested again. He was put in the Tower of London for breaking the law. His cell in the Tower was a dark and dreadful place.
The king's brother was a great friend of William Penn. He tried hard to have the young man set free. At last he brought it about.
Penn's father died soon after his son came out of prison. William was now a rich man. He went again and again to the king, begging that Quakers should not be whipped or put in prison.
At last he spoke of money which the king had owed his father. He said:
"You need not pay this money back to me if you will give me land in America where the Quakers can have a free and happy home."
The king was willing to do this, for he owed a good deal of money and found it hard to pay his debts.
The poor Quakers were allowed to come out of prison and seek a home across the ocean. They called the country that the king had given Penn, Pennsylvania, which means Penn's woods.
