George Wentworth closed his door when he was alone, drew the mass of papers, which Kenyon had left, towards him on his desk, and proceeded systematically to find a flaw in them if possible. He said to himself: 'I must attack this thing without enthusiasm, and treat Kenyon as if he were a thief. I must find an error in the reasoning or something shaky about the facts.' He perused the papers earnestly, making pencil-marks on the margin here and there. At first he said to himself: 'It is quite evident that the mining of the mica will pay for the working of the mine. We can look upon the demand for mica as being in a certain sense settled. It has paid for the working of the mine so far, also a small dividend, and there is no reason to think it should not go on doing so. Now, the uncertain quantity is this other stuff, and the uncertain thing about this uncertain quantity is the demand for it in the markets of the world, also how much the carriage of it is going to cost.' Wentworth had a theory that all things were possible if you only knew a man who knew _the_ man. There is always _the_ man in everything--the man who is the authority on iron; the man who is the authority on mines; the man who is the authority on the currency, and the man who knows all about the printing trade. If you want any information on any particular subject, it was not necessary to know _the_ man, but it was very essential to know a man who can put his finger on _the_ man. Get a note of introduction from a man who knows _the_ man, and there you are! Wentworth touched his bell, and a boy answered his summons. 'Ask Mr. Close to step in here for a moment, will you, please?' The boy disappeared, and shortly after an oldish man with a very deferential look, who was perpetually engaged in smoothing one hand over the other, came in, and, in a timid manner, closed the door softly behind him. 'Close,' said Wentworth, 'who is it that knows everything about the china trade?' 'About the china trade, sir?' 'Yes, about the china trade.' 'Wholesale or retail, sir?' 'I want to get at somebody who knows all about the manufacture of china.' 'Ah, the manufacture, sir,' said Close, in a tone that indicated this was another matter altogether; 'the manufacture, sir; yes, sir, I really do not know who could tell everything about the manufacture of china, sir, but I know of a man who could put you on the right track.' 'Very well; that is quite as good.' 'I would see Mr. Melville, if I were you, sir--Mr. Melville, of the great Scranton China Company.' 'And what is his address?' 'His address is----' And here the old man stooped over and wrote it on a card. 'That will find him, sir. If you can drop a note to Mr. Melville, sir, and say you want to learn who knows all about the production of china, he will be able to tell you just the man, sir. He is in the wholesale china trade himself, sir.' 'Would he be in at this hour, do you think?' 'Oh yes, sir, he is sure to be in his office now.'
