A sudden thought came to Dr. Graham. "Empty your pockets," he said.
"How lucky I put the bills in my stocking!" thought Sam.
He turned out his pockets, disclosing fifty cents. It was Friday, and to-morrow his weekly wages would come due.
"That's all I've got," he said.
"Twenty dollars is five weeks salary," said Dr. Graham. "You ought to work for me five weeks without pay."
"I'd starve to death," said Sam, in alarm. "I wouldn't be able to buy anything to eat."
"I can keep back part of your salary, then," said his employer. "It is only proper that you should suffer for your negligence."
At this moment a friend of the doctor's entered the office.
"What is the matter?" he asked.
