"I am sorry to part with you, Harry," said Professor Henderson. "You have been a very satisfactory and efficient assistant, and I shall miss you." "Thank you, sir," said Harry. "I have tried to be faithful to your interests." "You have been so," said the Professor emphatically. "I have had perfect confidence in you, and this has relieved me of a great deal of anxiety. It would have been very easy for one in your position to cheat me out of a considerable sum of money."
