there is no occasion for this

  "You appear to have confidence in me."   "Yes, sir."   "Then it is only fair that I should have confidence in you."   Luke looked puzzled, for he didn't quite understand what was in the gentleman's mind.   "I will take both of your papers. Here is a five-dollar bill. You may bring me the change to-morrow, at my office, No. 155 La Salle Street. My name is Benjamin Afton."   "But, sir," objected Luke, "there is no occasion for this. It is much better that I should trust you for two cents than that you should trust me with five dollars."   "Probably the two cents are as important to you as five dollars to me. At any rate, it is a matter of confidence, and I am quite willing to trust you."   "Thank you, sir, but----"   "I shall have to leave you, or I shall be home late to dinner."   Before Luke had a chance to protest further, he found himself alone, his stock of papers exhausted, and a five-dollar bill in his hand.   While he stood on the corner in some perplexity, a newsboy crossed Randolph Street, and accosted him.
