"Oh, you can't have forgotten me, Mr. Ferguson," said Al. "My name is Allston; don't you remember the interesting conversation we had on the train this morning?"
"Ahem! I think I do recognize you now."
"I thought you would. Isn't this rather early for you to be out, Mr. Ferguson?"
"I have not yet returned to my home; I have been on an errand of mercy. And now I must ask you to excuse me, for I am greatly fatigued."
"Wait a minute."
"Well, what is it?"
"I suppose you have often heard it said that justice and mercy ought to go hand in hand."
"It is a very true saying, my lad."
"Well, you say you have just been on an errand of mercy; suppose you now perform an act of justice."
"What do you mean?" demanded Mr. Ferguson, uneasily.
