“By the way, boys, have any of you seen that illustrated classical dictionary of mine? I had it in school about ten days ago when I was showing you the prints of the dress and armor of the Romans, and I have not seen it since. I fancy I must have left it on my table, but I cannot be sure. I looked everywhere in my library for it last night and cannot find it. Perhaps if I left it on the desk one of you has taken it to look at the pictures.” There was a general silence. “I think it must be so,” Mr. Porson went on more gravely. “If the boy who has it will give it up I shall not be angry, as, if I left it on the desk, there would be no harm in taking it to look at the pictures.” Still there was silence. “I value the book,” Mr. Porson went on, “not only because it is an expensive work, but because it is a prize which I won at Durham.” He paused a moment, and then said in a stern voice: “Let every boy open his desk.” The desks were opened, and Mr. Porson walked round and glanced at each. “This is a serious matter now,” he said. “Ripon, will you come to the study with me and help me to search again. It is possible it may still be there and I may have overlooked it. The rest will remain in their places till I return.” There was a buzz of conversation while the master was absent. On his return he said: “The book is certainly not there. The bookshelves are all so full that it could only have been put in its own place or laid upon the table. Ripon and I have searched the room thoroughly and it is certainly not there. Now, boys, this is a serious business. In the first place, I will give a last chance to whoever may have taken it to rise in his place and confess it.” He paused, and still all were silent. “Now mind,” he said, “I do not say that any of you have taken it--I have no grounds for such an accusation. It may have been taken by a servant. A tramp may have come in at the back gate when you were all away and have carried it off. These things are possible. And even were I sure that it had been done by one of you I should not dream of punishing all; therefore for the present we will say no more about it. But in order to assure myself and you I must ask you for the keys of your boxes. The servants' boxes will also be searched, as well as every nook and corner of the house; and then, when we have ascertained for a certainty that the book is not within these four walls, I shall go on with a lighter heart.”
